We’re hearing a lot of buzz about Zantrex 3, so we focused our attention on ingredients, side effects, customer service and scientific research. Furthermore, we scrutinized hundreds of consumer reviews and comments. We then detailed and summarized to give you the info you need.

Zantrex 3 Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Zantrex 3?

To begin with, Zantrex 3 fat burner is a supplement containing yerba mate, guarana, trimethylxanthine, damiana, green tea, kola, schizonepeta, black pepper, rhodiola crenulata, Asian ginseng, maca, cacao and black tea. The recommended serving size is two capsules prior to meals to supposedly assist with weight-loss. One of the benefits of the product is the ease of use.

The product, introduced more than 20 years ago by Zoller Laboratories/Basic Research, doesn’t appear to use synthetic ingredients, a good decision. You can buy the supplement on the official website and through trusted retailers. We do like the length of time the company has been in business and the money-back guarantee, but read on…

Zantrex 3 Side Effects – “Leaves You Shaky?”

The first concern we had was Zantrex 3 side effects. “Several fat burners contain caffeine-style ingredients,” said our Research Editor. “But when formulas contain additional thermogenics, there is a chance of adverse reactions.”

“After using Zantrex-3 the second day, within 15 minutes after taking this supplement, my face felt as though it was on fire and was getting more red by the minute. As I glanced at my arms and hands, they too were turning red,” said one user.

“I have been taking it for a week and have never felt so sick in my life. I started with one pill twice a day and bumped it up to two twice a day. Didn’t make a difference. I feel so sick every time I eat. Dizzy, nauseous, headaches,” offered a dieter.

FDA Judgments – “A Concern?”

In January of 2005, Basic Research was contacted by the Food and Drug Administration about the mislabeling of supplements. According to the complaint, products were claimed to affect “the structure or function of the body.” This is not allowed under current laws. The statements have since been removed.

Ineffectiveness – “Just Doesn’t Work”

In our review, the consensus was the Zantrex 3 ingredients were ineffective. “Unfortunately, this did energize me, but didn’t help me lose anything. 1 bottle down and drum roll please…..I have gained 3lbs,” reported one customer.

“Used this with no results a few years back. Very disappointing! I exercised faithfully as well,” said a consumer.

“This product didn’t do anything for me. I eat a lean diet and exercise 6 days a week. I noticed no difference,” offered a user.

Our research has shown that if a portion of a weight-loss system is a concern, such as effectiveness, there’s a chance you will not notice success in the long-term. If Zantrex 3 is ineffective, that could be a problem.

The Science – “Legit Ingredients?”

The official Zantrex 3 website states user’s experienced “546% more weight loss,” but we can’t locate clinical trials to that effect. There’s no trouble finding research into green tea or caffeine, but you’ll also find supplements with these ingredients by the thousands. At DietSpotlight, finding science backing claims is critical. If a company can’t provide support, we have concerns.

The Bottom Line – Does Zantrex 3 Work?

So, we’ve reached the end of the road with this one and what’s the final take? There are positives, like a few favorable customer comments and the fact that the company has a strong foothold in the industry, but have reservations recommending it because of the lack of scientific research supporting weight-loss claims. Plus, we’re concerned about FDA judgments against the business and several complaints posted on ripoffreport.com.

If you’d like a complete body turnaround, we suggest going with a product that’s both cost effective and clinically proven that’s had no negative interaction with the Food and Drug Administration.

Among the best products we’ve seen this year is our supplement called Dietspotlight Burn. The formula contains a four-ingredient blend, clinically-tested with results often found in studies such as The American Journal of Clinical Nutrition.

Also, we’re so confident that you’ll love our supplement, that we’re offering a Special Trial Offer, which is a great sign.

Previous Zantrex 3 Review (Updated July 16, 2014):

What You Should Know

The Zantrex 3 product is manufactured by Zoller Laboratories. This company prides itself on the fact that the item does not contain Ephedrine. Unfortunately, the official website for the product does not have much information. A person may be able to rely on third party website for more facts about Zoller Laboratories. They do have an official website, however. An individual can explore the Zantrex 3 product as well as purchasing information. The site offers information about the product in a sales pitch format, but detailed information is not present. A potential customer can also view a video of the type of benefits that Zantrex 3 can offer an individual looking to lose weight. The company claims that both men and women can receive substantial benefits from this product.

List of Ingredients

The official website does not offer a list of ingredients for review. Nevertheless, a third party site listed all the ingredients in Zantrex 3. These are: Green Tea Extract, Damiana, Schizonepeta, Tibetan and Panax Ginseng, Maca Root, Kola Nut.

Product Features

The manufacturers of Zantrex 3 claim that their diet tablet is designed for large amounts of weight loss, extreme energy and increased stamina. They also state that their product is the best on the market because they go well beyond a fat burner stimulant. The manufacturers of Zantrex 3 insist that their merchandise will assist a person in gaining more energy for exercise as well as acting as a rapid weight loss tool. An individual can purchase this product directly from the official website, an online retailer or from a local store. The cost of the product for 84 capsules is around $50.


  • An individual can purchase the Zantrex 3 product from the official website.
  • A person can view some information about the item, watch a video and learn a little bit about the company.
  • Several locations are available for purchasing this item. A savvy shopper could find some cheaper prices this way.
  • The components found in Zantrex 3 are natural.


  • Detailed information about the product or the company cannot be found on their official website.
  • They do not have a list of ingredients presented on their official site either.
  • The product is fairly expensive.
  • A large amount of caffeine is found in the ingredients of the Zantrex 3 tablets.


The Zantrex 3 product sounds great in theory. Nevertheless, when a diet supplement contains large amounts of caffeine we always get a bit weary, since caffeine has been linked to various negative health effects. The Zantrex 3 Side Effects touches on this. The official Zantrex 3 website is designed more as a sales pitch and a purchasing tool than as an informative web presence. A person may need to locate a third party website for a complete guide to the Zantrex 3 product. An explanation of ingredients, testimonials or benefits may also be found at these locations, but we'd like to see more about Zantrex 3 from the manufacturer's themselves!

We dug deep into the Zantrex 3 ingredients in order to provide you with the important facts and details.

Yerba Mate

Yerba mate is a plant that grows in countries such as Argentina, Paraguay and Brazil. It has been used in medicine to treat constipation, diabetes, depression, urinary tract infections and fatigue. Furthermore, it’s found in a number of energy drinks and diet supplements for weight-loss.

What is it Supposed to Do?

Yerba mate contains caffeine, which is a stimulant that boosts energy levels, improves focus, reduces fatigue and may help increase metabolism. Therefore this herb may assist with calorie burning.

Clinical Research

While this herb does contain some caffeine to improve focus, according to the Mayo Clinic, “Proponents of yerba mate say that it can relieve fatigue, promote weight loss, ease depression, and help treat headaches and various other conditions. There’s no definitive evidence that these claims are valid.”

Clinical research is an important part of the equation when it comes to choosing a diet supplement. Therefore, we recommend that you take a look at a product like Dietspotlight Burn. It contains powerful ingredients that are backed by actual science.


This is a stimulant and mild diuretic that comes from natural sources such as tea leaves, coffee seeds, guarana and yerba mate plants. It’s commonly found in energy drinks, teas, coffee beverages, chocolate and many diet pills.

What is it Supposed to Do?

Caffeine is a stimulant that affects the central nervous system. It has been shown to boost energy levels, reduce fatigue, improve concentration and even stimulate metabolism. It’s often used in weight-loss supplements to reduce appetite and increase calorie burning.

Clinical Research

There is some research that supports the effects of caffeine for weight-loss. For instance, MedicinePlus.gov says, “Caffeine has many effects on the body’s metabolism, including stimulating the central nervous system. This can make you more alert and give you a boost of energy.”


Guarana is a plant that grows in regions like Brazil. It’s also known as Paullinia cupana or Brazilian cocoa. This plant is sometimes used to treat anxiety, headache, poor mental performance, malaria, diarrhea and joint pains.

What is it Supposed to Do?

Like kola nut, yerba mate and coffee seeds, guarana contains caffeine. This stimulant may help with weight reduction by elevating metabolism and reducing hunger. This is why it’s used in many over-the-counter diet products.

Clinical Research

According to WebMD, “There’s some evidence that guarana – when used along with other supplements – may promote weight-loss. It’s uncertain if the guarana specifically was responsible. Because caffeine is a stimulant that has been shown to improve mood and aid weight-loss, guarana may very well also have these effects.”

Is There Anything Out There That We Think TRULY Works?

We did find one supplement that hits the mark. Dietspotlight Burn is formulated with key ingredients that HAVE been clinically tested. Be aware that all customers can take advantage of a Special Trial Offer, currently available. Click here to give it a shot.

Zantrex 3 Side Effects:

After hearing numerous dieters asking about potential problems with Zantrex 3 we decided to take a close look at Zantrex 3 side effects. The ingredients and clinical research were part of our research. We read hundreds of experiences, picking through the comments for facts. Then, we took all that information and condensed it to give you the bottom line.

What You Need to Know

First off, Zantrex 3 is a fat burner with guarana seed, yerba mate, trimethylxanthine (caffeine), green tea leaf, kola seed and more. You are supposed to take two capsules 15 minutes before each meal. The company claims this will boost weight-loss. You can choose to take a couple with you or throw the whole bottle into your bag.

The product, offered up by Zoller Laboratories, is made from all-natural ingredients, always something to look up to. The supplement is available through various websites and in stores. We like that the company has been in the business for more than 10 years and there is a strong BBB rating, but read on…

Headaches – “Ouch!”

The first problem we found mentioned with Zantrex 3 side effects was headaches. “If there is a consistent report found multiple times from different dieters, you need to take that into consideration,” says our Research Editor. “In the case of Zantrex 3, pain appears to be an issue.”

“Dizzy, nauseous, headaches…this isn’t worth it. I feel like total garbage. And I tried to work out today and felt like I was going to pass out when I finished,” said a dieter.

“Ive noticed that its been giving me a really hard time to sleep and sum really bad headaches! is this normal?,” claims another.

The same issue came up time and again, “I had this ghosting headache and felt just odd in general (not to mention that I could never get to sleep).”

Increased Heart Rate

We also found multiple dieters talking about increased heart rate. “It made my heart rate so fast and rapid it was dangerously fast,” one user explains.

Another experiences the same, “Racing heart, vomiting, excessive energy. Not recommended.”

Somehow for some there was also fatigue, “Somehow the confluence of ‘extracts’ produced both heart-pounding jitteriness, as well as an ‘out of it,’ dazed sense of malaise.”

The Science

We looked for research into Zantrex 3 but the only study we found did not have a link so dieters can’t read the complete report. When we looked for clinical support, we found the opposite. A study published in the Journal of Dietary Supplements reported some rather bad side effects. Then, “after discontinuation of Zantrex – 3, the patient experienced no further [side effects].” We need science at DietSpotlight. Without that we can’t see a reason to give the product a try.

The Bottom Line

Our look at Zantrex 3 side effects was quite interesting. We found positives, like a strong BBB rating and some supportive customer reviews, but we can’t recommend a supplement that is not clinically proven. We’re also concerned by the headaches, jitters and increased heart rate reported by dieters using the formula.

If you’re at the point you want to lose more weight, our suggestion is to try out a supplement that’s backed by clinical research to help you lose more without the risk of side effects.

Among the best supplements we’ve encountered this year is Dietspotlight Burn. This product comes with a proprietary blend of four ingredients shown in published clinical research to help boost metabolism and spark fat loss. We searched high and low for reports of harmful side effects and found none. What we did locate were some dieter comments offering details about amazing results.

Plus, the company that makes Dietspotlight Burn is confident in the supplement, so they’re offering a Special Trial Offer, a good sign.

How old do you have to be to use this product. Sixteen? Thirteen? Twenty?

Victoria (Editor)

Hi! For detailed product information and age requirements, please refer to the Zantrex official website for more information.


I’ve read reviews that say side effects of Zantrex are skin turning red and itchy.
That sounds like side effects of taking Niacin, B-3.
If Zantrex has Niacin in a dose of 100mg or larger? You need to eat something first before taking the dose.

Maribel (Editor)

Hello J.D. All users are different and can experience different side effects; please make sure to consult with your physician before taking this product.

  take it 15-30 minutes before eating
Kitten (Verified User)

I take the capsule stuff. I was just curious do I have to take it 15-30 minutes before eating? There are times that I would get so busy doing something that I would forget that I didn’t eat anything all day. So, I just wanna know if that is safe or if I should make sure to take it and not forget only to remember like 6 hours later or something.

Victoria (Editor)

Hi Kitten, for detailed product instructions please refer to the official Zantrex 3 website.

  Only have the reaction
Sherry (Verified User)

Alice, I’ve been having the exact same issue and affect with it. I am allergic to sulfa and haven’t seen anything on the bottle telling me it had sulfa in it. I take it twice a day, but I only have the reaction maybe once every other day or so. So I thought maybe it was what I was eating with it, or like maybe I wasn’t eating enough with it. I’m a little lost and just looking for a good fat burner.

I’ve tried the blue bottle which did not work for me i actually became extremely sick from the blue bottle but use the red bootle which works amazing for me and gives me a great energy boost for a great work out but every one has different reactions to things i would find it odd that it would make you constipated because thats a way of losing the weight but maybe add some flax seed to your diet that should help loosen your stole

Jon (Verified User)

I took Zantrex 3 for the first time this afternoon. I took the recommended 2 capsules and about 3 hours later began having severe anxiety. In fact I still am, and am considering going to the ER if it doesn’t let up soon. I nearly fainted and became numb all over for a few moments. It’s like a panic attack that won’t go away!! This is awful!!


The same thing happend to me after having my third baby I felt like I needed to get rid of a few pounds. So took zantrax 3 the blue bottle for just about a lilttle over a week and I started having anxiety attacks. Having 3 lil babies and no one around 24 7 with me it was scary. It’s been almost a year and I still get the anxiety attacks my doctor said that it made have effected my hypothyroidism I guess that if you took this for a long a wail it can creat a goiter. Witch I think that’s my case. But if I were you just stop taking them.

Zantrex 3 official website

Hello Alice, for the exact ingredients please refer to the Zantrex 3 official website.

  Do diet and exercise with it.
Yuri (Verified User)

Took the Zantrex 3: Fat Burner (Red Bottle), which is completely different from the Blue Bottle. Red Bottle contains a formula that encourages more Fat Loss than the Blue Bottle.
Do as I do for maximum results:
I am 18 years old, and currently am preparing to join the Navy. To condition myself and shed off a few pounds, I bought a two 56-Capsule Red Bottle set for $20 (Sincere thanks to Walmart).
I consider myself someone of slightly smaller stature. I was 115 lbs 6 months ago, but due to neglected physical activity, I have gained at least 6 pounds since then, to 121 lbs. I haven’t exercised in 2 years due to my more than adequate metabolism and Asian diet. I also never was much of an athlete.
Anyway, the first day I took it, I did my first run in ages: a 3 mile jog without stopping. I highly recommend that to achieve the best results, you start off on the max, taking as many pills a day as the bottle recommends (2 in the morning, 2 with your main meal, for a TOTAL of 4 in one day.)
Because this was my first time exercising in what seemed like forever, I naturally began to feel lightheaded and woozy after my workout. I was guessing it had to do with the pills, but this feeling should be natural for someone who is exercising for the first time in a while. Anyway, after my run, I did some thigh workouts until my legs felt like jelly.
Before the exercise and the pills, I weighed myself to approximately 119.8 lbs. Directly AFTER the exercise, I weighed 117.8 lbs. I lost 2 whole pounds in 1 day (presumably a few hours.) While you may say that this may be a combination of water loss from sweat and fluids, I did in fact intake a lot more water after the exercise, compensating for the loss.
I will continue to use the Zantrex 3: Fat Burner formula, with a workout routine of 1.5 – 3.0 mile jog almost everyday of the week, and an adequate diet (Fruits, Veggies, and Fish). I recommend you follow my routine. Make sure to drink LOTS of water throughout the same day you take the pills. No joke: don’t take the water thing lightly; you MUST drink a LOT of water, maybe so much that you can’t anymore. Before your workout, I recommend Gatorade, or any sports drink that provides you with enough electrolytes to keep you hydrated throughout the day and prevent wooziness.


Raven here using the Skinnystix berry flavor so far purple bottle mix with 16 oz of water. Tastes good and didn’t need a nap today. Only had one today been sipping slowly throughout the day. Honestly I got it cause I wanted the purple bottle for other drink mixes at first. The shape of it fits my small hand perfectly. Then I read all the ingredients. Looked up more about caffeine contents in different drinks to remind myself because I have a known problem with caffeine so I have to be careful so I can sleep at night. Right now though I think I like this and I am giving it a try.

I have taken zantrex 3 (red bottle) and love it. Although I did stop because I wanted to try the hcg1234 diet which I have witness some family shred the weight from it. My question is can I take the hcg1234 drops and zantrex together? If so should how? also i only want to take this for a short period because I know it is not good for you but I tried the old fashion way and that did not work. Thank you.

I am 18 overweight for my height. I saw Zantrex 3 on tv, but I was skeptical. I just started taking it today. I only took one pill, just so I could see how it made me feel. It actually wasn’t bad, I didn’t feel jittery or anything. I felt like I had way more energy than normal, and I hardly had an appetite. I weighed myself when I got home from work, and I lost a pound. So far, I like it. I’m going to move up to two pills a day and see how it is. I really like it so far. Hope this helps 🙂

It’s true. I know it says not to take it under age 18, but I am almost 17 and I wanted to try it out. I work at sonic for about a year now, and am used to eating their food daily. I used to weigh around 120 lbs and am now up to 150 lbs. I am a cheerleader so I workout, but not as much as I should be. I am also addicted to junk food. Ive tried so many times to stop my addiction, but it never works. So I bought the blue zantrex 3 pill, and it’s the best choice I’ve ever made. (however, I can’t swallow pills so i just pour the powder in a water bottle instead) It gives me incredible energy and no appetite. The the junk food i once loved, looks discussing to me. Ive already noticed a huge difference in just one week. I defiantly recommend it. The only side effect is that I always feel constipated. Like I never have to poop. Is that a problem? well good luck!!!


Hey liana I Saw your post and I’m also 17 and I was wondering if you had any side affects when you took the pills because I’m also 150 and I really want to loose weight fast but I’m scared to take this pills


i am a mother of three teenagers and i am 40 i weighed 300 and i have been taking zantrex3 blue bottle since april and on my second bottle and i cheanged my diet and cut certain things out and water and excersising ,i hve lost 15 lbs and i feel great and i have alot more to loose but i have sleep apnea and chronic back pain and fibromyligia and since my life change i dnt have so many problems or and i have been riding 12 miles a couple times aweek and i feel great,, i have no side affects … i recomend to any one that need to loose weight ! thank u so much zantrex3


Hey Liana. Well, I am a 43 yr old mama of 5 and you remind me of my 20 yr old daughter she cannot swallow pills niether. I will give her your advice , that is one way to get an iron tablet down, lol In addition, I am trying to lose weight and bought the red bottle. You said you are constipated. No, that isn’t good I have to say. I have had many problems with that and started out with diet products. If you have trouble using the restroom, do not let it go. Seek professinal help. A doctor and give you advice on what to take to help that out. OR, take miralax everyday, every morning to get things moving along. That is all I have to say, I am just a little bit worried. Good luck with your weight loss!

Bear with me this may be a little lengthy. I hit my max weight of 167 (when typically averaged between 130-135) I was miserable. When I realized I was no longer able to keep up with my Marine husband I knew I had to do SOMETHING. During his third tour I proscrastinated. 7 weeks prior to his return I was desperate to lose something. I heard about Xantrex 3 (blue bottle) and figured I had nothing to lose. I consulted with my doctor and had the good to go. I simply cut my love for coffee, soda pop, and sweets. I went to the gym 3/4 times a week and did 20 minutes of inclined cardio on the treadmil, lifted free weights, and worked on my abs with a excercise ball for 40 minutes. I was taking one pill in the mid morning, one mid afternoon (prior to working out) and one before dinner (not later than 4/5pm)Hence I also portioned my food intake more caringly. As one diagnosed with insomnia and not medicated I only experienced a few restless nights the first week. I was sure to drink A LOT of water and not intake any other form of caffeine and IT WORKED (for me)7 weeks later I was at a healthy 134.. 33 pounds less than I was 7 weeks prior. Not to mention only because of a previous comment left. I had a follow up with my doctor along with numerous blood panels performed and my well womans exam and everything was normal. (Beside that my doctor still wants me to quit smoking.. I know I know!)However it worked! I am a normal mid twenties, unpaid, Marine wife that had nothing to lose. In conclusion, everyone is different. Consult your doctor, take in moderation according to how your body reacts, drink a lot of water, and don’t be ashamed to tell others that your taking a diet supplement- just incase you do have a reaction. Good luck! Rant over 😉

I have gone through 2 bottles and now on 3rd. I started b/c I wanted to lose the last 10 lbs. In my opinion if you follow the guide you will have all of the poss. side effects. What works for me is to take one in the morning and that is it. Sometimes I take one before lunch but usually not. I have lost 5 lbs w/o exercise and watching what I eat somewhat. I am able to enjoy all foods b/c of the one pill. If I really wanted to be strict on my eating and exercise I could lose that last 5 lbs. but how much fun is that really?

I have always been overweight. I bought Zantrex-3 on November 18th and took it until December 17th because I went home for the holidays and forgot them. During that time I lost 11 pounds with minimal exercise and no dieting. During the holidays I started Calorie counting and lost another 6 pounds on my own. Now, I am calorie counting along with Zantrex3 and have lost nearly 20lbs total. The first few days on this are tough, but almost every form of dieting has hard times. Figure out what amount is right for your body. For calorie counting assistance try MyFitnessPal.

  Is this safe for my age?

Are there any seniors who have tried this pill? I work out 3x a week and o a samba class once a week. I have read all comments. I bought this diet pill but am afraid I might have a heart attach or kidney and liver problems. I only want to loose 15 lbs but I do need to sleep. Any seniors comment?

I am also very excited about this X3. Today is my first time taking it. I took one pill after I ate a little oatmeal this morning and I took another one after I ate a bowl of soup for lunch and I have no jitter yet. I just had a baby and I need to get back.
I was a 172 before getting pregnant and now about a 191. My goal is to lose 41 pound, I hope to lose it in six months and this is a realistic goal. Even, though I hope to lose the weight fast but I don’t want to hurt my body in the process. Thanks to everyone for their opinions, because I feel very comfortable after reading all your posts. Good Luck everyone, taking charge of your body and health is a must!!

Took my first two pills yesterday 15 mins before my supper with a lot of water and the side effects were terrible. Took them at 6:30 by 8 I was dizzy and felt like i had morning sickness. I wanted to work out but was so sick i couldnt, so i went to bed at 9, woke up at 11 and couldnt fall back asleep till 3! A lot of caffeine for someone who never drinks coffee or tea! Today I lowered my dosage by only taking one before my breakfast at 9, post later to let know how the side effects are!

It wears off I promise, after a few days you won’t even have sympthoms. Eat with it though. I love it(: want to get down to 120!!! Good.luck

  Tips on taking Zantrex
Kelly H (Verified User)

I would like to suggest that people who would like to lose weight start taking fish oil in addition to their other diet supplements. It will speed up metabolism, help lose belly fat and good for your heart. It helps decrease the jitters that you can get with Zantrex so take them together. Also take milk thistle with Zantrex to protect liver and kidneys.

Right now I weigh 115 pounds. I know that is not a lot, but there is still some extra fat on my body that I would like to loose that I can’t seem to get off in the gym.

  Water retention while on product intake
Anonymous (Verified User)

I have a question for anyone who may have experienced water retension while taking Z3. I take 2 pills in the mid morn and my feet, ankles and calves swell, very uncomfortable expecially when I wear heels for work. anyone experience it ….does it go away?


Zantrex should actually have a diuretic effect because of the caffeine. I notice I get a little dehydrated and have to drink extra water. I’m a nurse and work in a cardiology unit. Fluid retention in the lower extremities is sometimes an indication of congestive heart failure. The Zantrex may be aggravating it by increasing your heart rate. Definitely head to your dr and have blood drawn to check your BNP just in case.

  It worked for me
TFM (Verified User)

I used Z3 a few years ago and was amazed at my energy level. I would take 1 in the am and go for a 20-30 min walk, eat a little breakfast – oatmeal or granola bar, take another pill 30 min before lunch, and a 3rd pill around 5pm – even if I didn’t ear din then. If I had time I would walk again in the evening – I had enough energy to walk 30-45 min even after working all day. I found once Z3 was established in my system the energy stayed constant. I still drank coffee, and if I still felt “wired” after the sun set I would take 1 nighttime acetamenaphin tablet to help slow me down. I found helpful to take a multivitamin at night before bed. I was 155 and am 5’9″, have since had a baby and am now in a position to use Z3 again (hoping for similar results – so far so good!).

I started taking this pill 5 days ago. I can tell a huge difference in my energy level. I had low thyroid as it was so I had NO energy at all. Now I am cleaning the house and clearing out the yard.

I have not really noticed a huge difference in my size, but I do not weigh myself so I can’t be sure.

well after reading all of the reveiws i was freaked out about getting headaches and feeling sic so i took my first 2 pills with food and lots of water…. there were times i took them and werent able to eat right away… and nothing. i havent had any bad side effcts. i also havent had any extreme energy. sometimes i feel like they keep me going but i dont feel a rush of energy. i started out taking 1-3 a day and a few days i took 6 but i mostly have only taken 4 per day. it has been one week since i started taking them and i have lost 4 lbs! when i first started eating healthy and dieting i was averaging 1.5 lbs per week. like i said i started taking them this week and because of my crazy schedule i havent been able to work out much this week although i m on my feet alot. and i also havent eaten as healthy as i have been eating. i think if i wouldve stuck with my exercise and diet i would have lost even more. either way 4 lbs in one week without much effort worked for me!

You have 2 types of cholesterol–HDL is the good cholesterol and LDL is the bad. If it was HDL you should have nothing to worry about.

I have taken Zantrex 3 for several years and have lost weight but recently in a routine blood test I was diagnosed with acute kidney failure. After a biopsy i was tld that my kidneys are 0% scar tissue and Zantrex may be the culprit. Has anyone else had this happen?


trish. i hate to hear about you kidney. but if you go get milk thristle and take 2x the amount it will heal your kidneys and liver. jo ann


It is possible that Zantrex 3 is the culprit though I’m not a doctor. I take anti-seizure meds and I have to drink additional fluids to prevent them from building up in my kidneys. One of the side effects is some weight loss. A friend of mine on a simuliar med with weight loss as a listed side effect had kidney failure as well. I noticed Zantrex 3 mentioned drinking a full 8-10 oz of additional water per pill. Perhaps, to pervent it from building up in the kidneys?
Of course this is nothing but speculation, but you might ask your doctor.

I only take two a day, one in the morning and one in the afternoon because it keeps me wide awake at night if i take one any later. For the price of this pill, it’s definitly worth every penny!


I’ve just started taking Zantrex-3. This will be my second day. I’ve been taking 2 a day in the morning and hour before a workout and I have been doing just fine. I have energy and I can sleep at night. I do feel a bit jittery but that usually happens to me if I haven’t ate the amount I’m used to. I’ll keep in mind all the comments and warnings from everyone… and let everyone know. But so far so good! 🙂

I just started Zantrex-3 today (11/13/2010). I took one capsule on a half empty stomach about 15 minutes. So far, I’m not experiencing anything. I’m about to eat some crackers just so that there’ll be a little something in my tummy. I was really scared by the negative reviews but I hope that stuff won’t happen to me. I currently weigh 155pounds and I’m 5’7. I’ll keep you updated on what happens in the next couple of days.


Rachel, I noticed that you posted on Nov 13th and no update. I really curious as to how your doing.

I had tried this, and it works great AS LONG AS YOU EAT FOOD WITH IT. I cannot stress enough how important it is to eat food then take it. A snack is not good enough, it has to be a legit meal. I took it at a half fulled stomach and my stomach completely turned. I cannot describe how painful it was. If that does happen to you immediately eat something for 5 mins and it will go away. Also NEVER take it right before you go to bed. The acid will enter your esophagus and irritate it. Hopefully this helps someone and good luck 🙂

  Just be careful to not take too much because it can make you sick and jittery.

I’ve taken this before, and it really does help me with energy, and especially my appetite. One of the reasons it’s always been hard to lose weight is because I’m ALWAYS hungry. This makes me not hungry all the time, and it makes me feel full faster. Combined with exercise and eating right, I think this is a really good tool to start losing weight. Just be careful to not take too much because it can make you sick and jittery. I only take 1 or sometimes 2 a day because I’m very sensitive to caffeine.

  Side effects while taking 2 capsules.

I have been taking 1 capsule at a time I moved up to two and headaches came I moved back down to 1 and good results no more headache.

   Zantrex 3 HAS worked.

My experience with Zantrex-3: I started off with one pill twice a day and moved on to two pills twice a day after a week, but that amount made me incredibly jittery and tense. When I was taking four pills a day, I had this ghosting headache and felt just odd in general (not to mention that I could never get to sleep), so I went back to one pill twice a day. While I had a relative boost in energy, I also had NO appetite, sometimes to the point that it made me nauseous just to think about or smell food. I had to force myself to eat (!). I’ve gone from 150lbs to 135lbs in the past three weeks. So altogether, I can say is that it HAS worked. But I’d recommend that everyone be very, very careful with it.


I do agree with them. I have been takeing it for awhile now and I have lost 55 lbs. I only take one in the morning before my breakfast and that last me all day. If I take more then that then i get the sick jittery feeling aswell. I thought since i have been taken them for awhile that i could try to take 2 a day lol dont do it just stick with one; you can go to sleep that way. I recommend it to anyone that wants to lose weight and have more energy. I even like taking it because i dont feel soo lazy in the mornings and actually get feel like dressing up and playing with my kids. I dont get so irritable with them either. but…. I do talk alot on them…I already had mine today lol


im wondering the samething as LESLEY!


Love it! I had a baby in December. Started taking Zantrex in February and I’m down 46 lbs now without exercise! It does make me feel nauseous at times, but the results far outweigh the side effects for me. I was losing about 5-7 lbs a wk when I first started taking it, it’s slowed down since then. Guess I’ll have to start exercising.




I just bought this and very excited to try it. One question though are you doing a workout with taking the pill too? If so what type of exercise are you doing?


I have been taken Zantrex-3 for almost a month now. with me working I never have time to work out but, I do walk a mile everyday after work. I have lost 15 pounds just by doing that.. I take 4 a day.. 2 before breakfast and 2 before dinner. I dont eat after 6pm. So yes working out plays a part but, Only if you want to see a big result in your weight loss.


I have taken Zantrex-3 for a week now and i have lost 5 pounds. I have several more pounds to lose, and i hope that my weight loss keeps up for me. I am only taking 2 pills a day right before my biggest meal of the day.


ya i really hope y all r telling the truth too cause i just had a baby and i really wanna lose wait… and im really close to ordering this product

  What happen when leave the product.
Farrann (Verified User)

After taking Zantrex 3 for a while and after losing the amount of weight one wants to lose, what happens when you quit taking it? Will you gain the weight back? Will you gain the fat back?

Common Sense

If you continue with a crappy, unhealthy lifestyle….duh.


Do u think a 13 year old girl should take it ?

No way!

No, a 13 year old should not take this. It does have side affects that can be difficult to handle. Vomiting, dizziness, and anxiety. It does give you lots of energy but, the bottle does say under 18 years of age to not use.

Victoria (Editor)

Hello Maggie, the majority of the Zantrex 3 product line is not intended for anyone under the age of 18. Please consult with a doctor before giving it to any minor.

Victoria (Editor)

Hello, as long as you maintain a healthy life style and exercise, you should be able to keep the weight off. You could always go back to it.




I bought Zantrex 3 and I had my doubts, but I swear on my kids’ life, I’ve lost 3 pounds in just one day! I am not kidding, no one is paying me to say this, I couldn’t sleep at all last night but I think I am just going to take 1 a day, I took one before breakfast and I took one before lunch, I was up until 4 am, but I am just going to take 1 a day. oh of course I dieted all day and walked a whole mile. Good luck, I am going to keep using zantrex 3.


there is nothing healthy in losing 3 pounds in one day. you are crazy to be excited about that. 3 pounds in a week, that should excite you because it would actually be a concrete result


If all you can do is put people down for there accomplishments then DONT comment!!!!! Your probably jealous. Congrats on the weight loss, hope I can be so successful with it


dont be hating on her let her have her joy prbably mad cause you fat


If you didn’t want to lose fast, you wouldn’t be looking into this product…. So hush!
