97% of dieters just want a product that’s effective. Yeah, we don’t understand the remaining 3%, either.

Then, we refined and summarized to give you the info you need.

What is Stacker 3?

To start, Stacker 3 is a fat-burner containing:

Other ingredients also include chitosan and caffeine 250mg. The recommended dose is one capsule, three times per day. Supposedly, it increases energy levels and weight-loss. The small size of the pill makes it easy to take on-the-go.

The supplement was introduced by NVE Pharmaceuticals Inc in 2003. You can purchase the supplement at your local retail stores by the bottle or in blister packs. We do like that the cost is reasonable and that a few Stacker 3 ingredients are natural, but read on…

Stacker 3 Side Effects – “Out of Body Experience?”

The first concern regarding the Stacker 3 side effects was stomach pains[3]. “When you take thermogenic supplements, you will notice changes like increased energy,” said our Research Editor. “But, dieters don’t expect adverse reactions.”

“I used stacker 3 xplc to improve my energy at work. I thought everything was ok at first but after a year of one pill a day it affected my kidneys. No stars only pain and regret,” commented a dieter.

“I took these once a day for five days with meals. On the fifth day I started experiencing serious side effects like dizziness, numbness in my fingers, and rapid heartbeat,” stated a user.

According to some Stacker 3 reviews, side effects are rare.

“After about a week or so I noticed that my energy level was higher and my workout intensity was slightly improved,” stated a user.

Stacker 3 Customer Testimonials

FDA Advisory – “A Major Concern?”

On several occasions, NVE Pharmaceuticals Inc. has been contacted by the FDA due to mislabeling supplements[4]. In April of 2004, the company received a letter warning of undisclosed ephedra in products. In September of 2012, the business received additional correspondence highlighting formulas with claims that were misleading[5].

Ineffectiveness – “Doesn’t Work?”

After researching, we found multiple cases where customers said Stacker 3 ingredients were ineffective. “I started this 1 month ago, using it as directed with normal diet & regular exercise, & I’ve gained 8 pounds!,” states a consumer.

“When I was taking it I didn’t lose any weight, I actually started gaining it!,” said a dieter.

We found that some users did notice changes while using Stacker 3.

The product has not helped me lose weight, but it does give me enough energy to exercise and work around the house for a few hours,” said a user.

It has the caffeine equivalent of around 2 large cups of coffee and I feel it keeps me going through a long days work,” reported another.

According to our research, if there is one issue, like ineffectiveness, chances of long-term success could be reduced. If Stacker 3 doesn’t produce results, we have concerns.

The Science – “Valid?”

There’s limited information relating to the scientific research supporting weight-loss claims. The caffeine in Stacker 3 may boost metabolism[6], but there’s no science showing the effects relate to this formula. For us at DietSpotlight, having published clinical data backing information is critical. If there’s no science-based information, what’s to keep the dieter around?

What Users Are Saying

“I can fall asleep after drinking caffinated coffee. For the past several months I have been taking Stacker 3 off and on as needed for the pick me up to help get through a tough work day, and these do the trick. Negative side effect are jitters but this does subside when I take them consecutively for a few days. Product even arrived a day earlier than expected! Will definitely purchase again.”

“Just ok!!”

“Did nothing for me.”

The Bottom Line – Does Stacker 3 Work?

So, will you lose weight with Stacker 3? Well, we like the longevity of the company and the inclusion of a few natural ingredients, but we have reservations about it because of the lack of published clinical research connecting it to weight-loss. We’re also concerned about the side effects and lack of results mentioned in customer reviews.

If you’d like to transform your body, we recommend going with a supplement that contains ingredients supported by published clinical studies with no reported harmful side effects.

Among the best products we’ve seen this year is one called Burn HD. The formula contains a four-ingredient, proprietary blend, shown in published scientific research to help enhance metabolism and spark fat loss. There are no comments about harmful side effects, but consumers are noticing amazing results.

Also, the makers of Burn HD are offering a 2-Week Sample. A good choice and a sign of confidence.

We really researched the Stacker 3 ingredients in order to give you the important facts and details you need.

Chromium Picolinate

Chromium picolinate is a mineral and chemical compound that’s found in a number of dietary supplements. It is an important mineral found in foods like tomatoes, broccoli, romaine lettuce, oats, green beans and barley. It’s imperative for overall health and wellness.

What is it Supposed to Do?

Often chromium picolinate[1] is a key ingredient found in weight-loss supplements. It’s intended to help regulate blood glucose levels and control food cravings. It also assists by converting carbohydrates, proteins and fats into energy.

Clinical Research

There is some research that ties chromium picolinate to weight reduction. For instance, “A study published in Diabetes Technology & Therapeutics in 2008 found that chromium picolinate supplementation helped overweight women who had carbohydrate cravings to better control their appetite and the amount of food that they ate, although it didn’t lead to a significant amount of weight-loss over the course of the 8-week study.”

Green Tea Leaves

Unlike oolong and black varieties, green tea is unfermented. It is widely consumed in Asia, and it’s well known for its health benefits. Also called camellia sinensis, these leaves are often said to help prevent cancer, boost immune system health, reduce cholesterol levels and even aid with weight reduction.

What is it Supposed to Do?

Green tea extract[2] is used in a number of herbal weight-loss supplements that are available over-the-counter. This ingredient is supposed to help boost metabolism and reduce unwanted body fat. It contains caffeine (a stimulant) and EGCG or catechins (antioxidants).

Clinical Research

According to the University of Maryland Medical Center, “Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight-loss and maintenance in people who were overweight and moderately obese.”


Taurine is essentially an amino sulfonic acid. Amino acids are the building blocks of protein. Some foods that contain this component include beef, sea algae, lamb, salmon and dungeness crab. It’s also found in significant portions in the human heart and brain.

What is it Supposed to Do?

There are many energy drinks, workout supplements and weight-loss products that contain taurine. This amino acid is supposed to help boost energy levels, burn off fat, prevent lean muscle loss and provide antioxidant protection from free radicals.

Clinical Research

There does not appear to be a direct correlation between taurine and weight reduction. However, according to WebMD, “Taking 2-3 grams of taurine by mouth one to two times daily for 6-8 weeks seems to improve heart function and symptoms in patients with moderate heart failure (New York Heart Association (NYHA) functional class II) to severe heart failure (New York Heart Association (NYHA) functional class IV). Some patients with severe heart failure rapidly improve from NYHA class IV to II after 4-8 weeks of treatment. Improvement seems to continue for as long as taurine treatment is continued, up to one year.”

We’ve found that side effects are rare when is comes to dietary supplements. That’s why one that’s caught our attention is Dietspotlight Burn. There’s no mention of adverse reactions and customers are seeing great results. Click above to learn more.

Stacker 3 Scientific Abstracts

Green Tea Extract

There had been significant weight-loss from 76.8 ± 11.3 kg to 75.7 ± 11.5 kg (p = 0.025), in addition to a reduction in body mass index (p = 0.018) as well as waist circumference (p = 0.023) following 12 weeks of a high-dose green tea extract treatment. The study had also shown examples of a constant trend of reduced total cholesterol, up to 5.33%, as well as reduced LDL plasma levels. In conclusion, it had been shown that 12 weeks of treatment with high-doses of green tea extract had led to substantial weight-loss, decreased waist circumference and a steady reduction in total cholesterol as well as LDL plasma lipids without any adverse side effects. [1]

Garcinia Cambogia Extract

Upon examination of the meta-analysis, it had been revealed that a statistically minor difference in weight-loss favoring hydroxycitric acid over placebo (mean difference: −0.88 kg; 95% confidence interval: −1.75, −0.00). In one study, there were twice as many negative gastrointestinal events recorded in the hydroxycitric acid group in comparison to placebo. It was concluded that randomized clinical trials indicate that Garcinia extracts can trigger weight-loss in the short-term. The magnitude of these activities is small and the clinical importance remains to be concrete. There need to be future trials with a more in-depth report. [2]


Mean alterations in body weight were-1.78 ± 1.37kg and -3.10 ± 1.95kg on the 45th day and at 90 days respectively within the chitosan group, which had been substantially different (p < 0.0001) in comparison to placebo. Body mass index had been reduced by 10.91 fold in comparison to placebo following administration for 90 days. Along with these findings there was also a decrease in anthropometric parameters and body composition combined for an improved QoL score. Chitosan had also been able to decrease HbA1C levels (below 6 %) in participants whose values were initially higher. Mean caloric intake displayed that there had been no differences in dietary habits of participants in either group. The lipid levels had not been affected and the adverse effects reported were minor and unrelated to the treatment in the study. Chitosan (from fungal origin) was successful in decreasing mean body weight up to 3kg throughout the 90 day period of the study. In addition to this, there had been an improvement in anthropometric parameters, body composition and HbA1C, showcasing the overall benefits for overweight consumers. There had also been an improvement in QoL score and was found to be safe and very well tolerated by all participants. [3]

What You Should Know about Stacker 3

Stacker 3 is a dietary supplement that is marketed toward men and women who desire assistance with weight loss. This supplement is manufactured by NVE Pharmaceuticals Inc. and sells in common drugstores, supermarkets and nutritional stores. Stacker 3 claims to burn away unwanted fat and boost energy levels. It sells in the form of a capsule and is directed to be taken daily with water. There are no customer testimonials for Stacker 3 offered on the official website. There are no free trial samples of Stacker 3 available. There doesn't appear to be a 100% money-back/satisfaction guarantee posted on the website for Stacker 3. Aside from this product, you may want to take a closer look at TruBio Trim as it is a probiotic supplement that is used to reduce excess fat, boost the metabolism by enhancing digestive support and induce rapid weight loss. The primary active ingredient offered in Stacker 3 supplements is Chitosan, which metabolizes fat. Similar to many other weight loss drugs, Stacker 3 is intended to be taken in conjunction with a healthy diet plan and regular exercise. No one under the age of 18 years old should consider taking Stacker 3 supplements. This dietary drug is not available via the official website. The website does not claim that Stacker 3 suppresses appetite. A full product ingredient list is not found on the website. NVE Pharmaceuticals Inc. additionally manufactures supplements like Stacker 2, 7-Phenyl Stack, Yellow Hornet and Swarm Energy. As it comes right to it, Fat Magnet promotes weight-loss by blocking the absorption of fat with few natural ingredients.

Product Features

Stacker 3 is a weight loss supplement that is claimed to help women and men reduce body fat. Similar products that claim to help burn fat are Vintage Burn and Quadralean. This dietary drug comes in capsule form and aims to increase energy as well. The key active ingredient found in Stacker 3 is Chitosan, which is a marine animal extract. Although this weight reduction product does not sell via the official website, it can be acquired in drugstores, supermarkets and nutritional stores. There doesn't appear to be any real clinical evidence provided on the official website to support the claimed effectiveness of Stacker 3 supplements. Warnings for this product are not offered on the website.

Advantages of Stacker 3

  • Stacker 3 comes in an easy-to-manage capsule form.
  • Stacker 3 can be easily purchased in most common supermarkets and drugstores.
  • Stacker 3 is suitable for both women and men, but not for individuals under the age of 18.

Disadvantages of Stacker 3

  • A full product ingredient list for Stacker 3 is absent from the official website.
  • There are no customer testimonials provided on the official website for Stacker 3 supplements.
  • There isn't any clinical evidence presented on the official website to support the overall effectiveness of Stacker 3 capsules.
  • Stacker 3 doesn't appear to be offered with a 100% money-back guarantee.
  • Some ingredients found in Stacker 3 may not be suitable for some individuals.
  • No free trial samples of Stacker 3 are offered via the official website.


When all is said and done, Stacker 3 is presented like many weight loss supplements. While it's claimed to boost energy levels and burn away fat, there is no clinical evidence to support this on the official website. What we like about this product is its intake of caffeine which has been known to help block adenosine receptors, a chemical found in the brain that causes you to feel fatigued or less energized. Furthermore, it would be nice to see some customer testimonials, a money-back guarantee, a full product ingredient list and free trial samples of Stacker 3 offered on the official website. When a manufacturer goes to the trouble of supporting their products this way, it shows that they really believe in what's being sold. It's probably prudent to consult your physician prior to taking Stacker 3 supplements.

  • Question about possible side effects

    does stacker 3 give irregular periods?

    • Cameron (Editor)

      We haven’t heard of this happening to dieters. Better have your doctor take a look Kim. In the mean time you might want to stop taking it.

      Hi Angel, because this product contains caffeine, its best to consult with your physician.

  • Would it cause side effect?
    jessica deem

    can this product cause me to be very mean and edgy? some other products do that.

    • Your Name


      • Your Name

        Yes. I only take Stacker 3 in the morning with breakfast and never after 10am or I can’t sleep at bedtime, which is 9pm. As long as I take it early, I’m fine.

    • Montana (Editor)

      Hello Jessica. From our research, we could not find any connection between Stacker 3 and mood changes. However, if you’re worried about using this product, you may want to consider using one that has clinically researched ingredients, like Dietspotlight Burn.

  • Will it mess with birth control ?

    I’m trying to lose weight so I’m giving slacker3 a try. will it mess with birth control? I just started the depo shot

    • Stephen (Editor)

      Please ask your doctor to look over the formula for you. What may be most affected with taking a diet supplement is possible reduction of your birth control’s efficacy. Green tea and Glucomanan, for example, may reduce the absorption of the birth control’s ingredients.

  • Guillermo Aguilera

    Back when I was in High school I was about 250 pounds. I was tired of being the biggest kid in my class and a friend recommended me to use stackers. I started them in May of 2009 and by September I dropped down to 170 pounds. I worked out for a hour daily, cut fast food, pop and candy and I was amazed at the results I got. I just started back taking them after a weight gain I experienced in college after fracturing my knee and I’m hoping for the same outcome!



  • Richard

    On Jan 1st I weighed 220. Two years ago and with the help of a six month prescription of diet med I went from 260 to 220 but had stayed at 220 for almost a year. I started Stacker 3 in Jan and today 9/8 I am 174. It increases the metabolism, makes you less hungry, and I have had 0 side effects with the exception of some mild high blood pressure. Hard to tell if it’s related or not because it’s always been slightly elevated. This loss is without hardly any physical exercise. I walk occasionally, do some stretches, some yoga stuff here and there (beginner’s stuff) so in my opinion it works. The year prior I ttoj a number if over the counter stuff that has zero impact. I’m a male, 53 years old

    • Montana (Editor)

      Hi Richard! Congrats on the weight loss success! If you’re looking to continue your weight loss journey, you might want to consider Dietspotlight Burn.

  • Maria

    I had one for my very first time. Made sure I had a good breakfast and had enough water with it. I work fast food so I wanted a little boost in the morning. An hour later I started having some really uncontrollable shaking throughout my whole body, very rapid heartbeat, dizziness. I couldn’t even hold anything in my hands, it was hard to stand as if my knees were bubbling and weakening at the same time. I was sweating all over everywhere and could barely hold a conversation. (I had to leave work) Wasn’t emotionally stable and had to get taken to the ER. NEVER trying again.

  •  kevin j (Verified User)

    Stacker 3 with chitosan– great product for me at 63 yrs old; lost 12 lbs and much more energy;
    i take one before i eat in morning; then my desire to eat is very low–no side effects except if i don’t take it= then im like a sleepy bear..

  • Rae

    My friend has been doing stacker 3 for 18 months now and has lost 60 lbs. I myself have been using it for just a little while and have had no side affects and some weight lose. I feel it works for some people who have the metabolism that works with it.
    Everyone is different. I maintain a ridged diet and exercise program and do not eat sweets or eat out. If you can do this, weight lose will happen. Good luck to all no matter what you take. Just remember it will only work if you can maintain a strong conviction to do so properly.

    • kendal

      • Tammie

        I have fibromyalgia myself and when I took the Stacker 3, three times a day it had no effect in my fibromyalgia symptoms.

  • Jamie

    So you would recommend this? I’ve taken it in the past just for the caffeine and it definitely work for that. And no issues with it wver, for me.But I’m thinking about trying it for weight loss. So you still take it?

    • Tammie

      I would. I just started taking it 2 days ago. I feel the energy but so far not liking the crash that follows several hours later.

  • bad stomach pains
    Morgan (Verified User)

    I took some yesterday and got real bad stomach pains. I work maintenance so I’m very physically active all day and needed a boost. I’m going to try them again today to see if maybe I just didn’t eat enough before I took them. But so far it’s terrible. I didn’t even get the energy I wanted from it.

    • Tina

      You are right you didn’t eat enough food you have to remember it’s a fat burner and it does work when you have pain you need to eat.

  • Stacker 3
    TRACEY (Verified User)

    I can’t seem to get any sleep

    • Tammie

      Try not to take it after 6pm. I don’t eat after 6 pm so that’s when I took my last dose of Stacker 3.

  •  improve energy at work
    Thomas Cook (Verified User)

    I used stacker 3 xplc to improve my energy at work. I thought everything was ok at first but after a year of one pill a day it affected my kidneys. I read the label and found meny warnings about my symptoms. I have no family history of kidney stones but I did develop a 13 mm kidney stone during the use of this product. I wish I would have been more aware of what harm stacker products can do yo my body. No stars only pain and regret.

  • Your Name

    • Karen.blair1989@gmail.com

      I used to have a big problem with 3 different types of drugs and thank God I was able to quit before my children came along. I now use stacker 3 XPLC and it makes me feel like I’m back to my old ways. But I take only 2 a day instead of 3 and I feel like I’m back doing what I used to do. I cook, clean, talk alot, and 8 have been asked the same thing by my family, but I went to take a drug test for them and all of them watching so they knew I was telling the truth. Clean as a whistle… but yes it will make her seem as 8f she is back on what she used to be doing. Hope that eases your mind a little bit God bless and may her sobriety Stay strong

  • I needed extra energy

    Trying the S3 XPLC, Been on it for less than a week. I have tried S2 before and did not really notice any weight decrease, but no jitter or negative impact on me. I have also tried the prescribed Phentermine, but that gives me bad dreams, and makes me edgy, short tempered so I stoppped it. It does provide great energy but that another story.

    For taking the stackers, if it is your first time around, I do recommend eating first. For this time, I needed extra energy to get pass the afternoons at work, it does provide good energy for about 2-3 hours, but then after you get so hungry. I just supplement it with eating fruits or drinking more water. So far so good. I have 3 of these bottles and hope to help me supplement weightloss plan with my strict diet – no rice & no red meat + more fruits and veggies.

    I used Stacker 3 for weight loss and all it did was make me nauseous, bloated and irritable.

  •  Some Peoples May be Allergic
    Tiffany (Verified User)

    Stackers are awesome!! Some people may be allergic to them and that is unfortunate, but still not a reason to not recommend them because obviously not everyone is going to have an allergic reaction. And the two MAIN things you need to know before taking this product is to drink plenty of water and get moving!!! Do not take this and then sit around all day because it will make you feel crappy. If you are up and moving you feel just fine! Love it love it love it (:

    • Your Name

      Did you lose weight?

  •  Didn't loose weight but gained much energy
    Jonathan (Verified User)

    I first used Stacker 3 for weight loss, and I did not notice any weight loss, but I did get a lot of energy. I now use it to pull al nighters for school. I think it really helps. I also lose the hunger for like 2-4 hours and then I get very hungry afterwards. I am just very satisfied with the amount of energy it gives me to stay awake and alert, and to workout even longer and more intensive. I think this may be better than the 5 Hour Power Energy shot.

  •  little extra energy
    Lindsey (Verified User)

    I take Stacker 3 to help increase the results of exercise and to get a little extra energy. If I take it without eating about 20 mins after I do get jittery, but if I do something active like a workout or cleaning the house or playing with the kids I do not get jittery. I like them just for the extra energy but apparently have not taken them long enough (less than 1 week) to see weight loss results. Overall, thumbs up!

  •  The New Stacker 3 xplc is potent
    MaureenE (Verified User)

    Years ago,I tried Stacker 2 then 3.. It was taken off the market,sadly. The New Stacker 3 xplc is potent.I ate first then took the pill.1st use and I was really jittery but had tons of energy(IM 41)
