I’m here to cut through the noise and get you the bottom line on Zantrex. Here at DietSpotlight we created an in-depth review, examining the side effects, ingredients, clinical research and level of customer service. Plus we scrutinized dozens of customer comments that are posted on the internet. Lastly, we summarized and condensed this information to provide you with the important facts.
What is Zantrex?
To start things off, Zantrex-3 is a dietary supplement that is made by Zoller Laboratories. This product is supposed to provide extreme energy, while encouraging rapid weight-loss. For maximum results, you must take two capsules 15-30 minutes before breakfast, lunch and dinner. Be sure to drink a full glass of water with each serving. This diet pill contains Niacin (30mg), Yerba Mate, Guarana Seed Extract, Trimethylxanthine, Damiana, Panax Ginseng, Kola Seed Extract, Black Tea Leaf Extract, Schizonepeta Flower Extract, Black Pepper Fruit Extract, Rhodiola Crenulata Extract, Green Tea Leaf Extract, Maca Root Extract and Cacao Seed Extract.
We are unsure when Zantrex was first released, but this supplement has been available since at least 2013. It is manufactured in the USA, and can be purchased online. A 30-day satisfaction guarantee is provided. This diet product is also available on dealer websites, but read on…
Side Effects – “Is it Safe?”
First of all, we are a little concerned with the possibility of Zantrex side effects. According to our Research Editor, “After reading some customer reviews pertaining to Zantrex-3, it’s clear that some people experience unwanted reactions. Naturally this is very concerning.”
One person stated, “I’ve been on it 3 days and I feel dreadful, so nauseous and a headache from the pills. I don’t think it’s worth the side effects. I’ve spent all of the 3rd day in bed.”
“Haven’t lost any weight and I am nauseous and have been in and out of the bathroom. I feel dreadful,” commented another user.
Negative User Reviews – “Another Big Concern”
We did see quite a few negative customer comments posted online for Zantrex. In fact, one person revealed, “Feel like I’ve wasted my money and feel sick no matter if I take 1 or 2, with or without food, I feel horrible.”
“I am just trying to finish the bottle so I don’t feel like I completely wasted my money! No energy boost, no appetite deterrent at all. I would never recommend this to anyone!,” said another customer.
The extensive research we’ve conducted has shown that if there is one aspect of a diet pill or weight-loss program that is quite concerning or difficult (side effects, negative user reviews, low Amazon rating) the likelihood of real results for the long run is minimal. So, if Zantrex does in fact result in a high number of unhappy users, this could be problematic.
What About Actual Science?
The official website for Zantrex-3 does not present any actual science to support this formula. While this supplement does contain some Green Tea and Caffeine to help boost metabolism, it’s unclear how much of these ingredients is actually used. For us at DietSpotlight, we like to see some real clinical evidence that supports the diet product and its weight-loss claims.
The Bottom Line – Does Zantrex Work?
Now the moment you’ve been waiting for: our bottom line on Zantrex. Well, we like that this diet pill contains some natural herbs and that it’s sold with a satisfaction guarantee. On the downside, we have some doubts because it’s not actually backed by any clinical studies or research. Furthermore, we’re concerned about the customer complaints regarding side effects.
If you’d like to drop more weight, then we encourage you to choose a product that does not cause any harsh side effects, is backed by solid science, is easy to use anywhere and comes with great customer service.
Among the best products we’ve seen this year is one called Dietspotlight Burn. This product contains a blend of four key ingredients, which have been shown in documented clinical research to help kick-start metabolism and speed up fat loss. Moreover, we can’t find any complaints of harmful side effects and customer feedback around the web shows people are seeing significant results.
The makers of Dietspotlight Burn are so satisfied with their product they’re offering a Special Trial Offer, which is a good sign.
Previous Zantrex Review (Updated August 14, 2014):
What You Should KnowZantrex-3 is a weight loss supplement that endeavors to assist with weight reduction, increase energy levels and aid the user's metabolism. This diet product sells through the official manufacturer website. However, little information is provided on the supplement via this site. Compared to other sites that we've reviewed, the official Zantrex-3 site is laid out like an infomercial or massive ad. Zantrex-3 is marketed toward both men and women and, similar to GNC Burn 60, Zantrex-3 is intended to be used in conjunction with a proper diet and a regular fitness regimen. Zantrex-3 is claimed to be Ephedra-free and is also sold in common nutrition stores. The official Zantrex-3 website does not appear to disclose how long the diet product has been on the market, nor does it offer any customer testimonials. Overall Zantrex-3 is claimed to assist with the dieter's energy levels, while boosting the immune system and curbing hunger cravings. No specific diet or exercise program is recommended. Although Zantrex-3 can be purchased online, no free trial samples are offered when ordering Zantrex-3. The official website does give a video clip advertising the dietary supplement as an energy boosting product, which we thought was an innovative form of testimonial.
List of IngredientsThere are a few primary active components found in Zantrex-3. These are Kola Nut Extract (stimulant), Yerba mate (a stimulant for the nervous system), Green Tea (helps the immune system and metabolic rates), Caffeine (stimulant) and Panax Ginseng (assists with proper blood flow).
Product FeaturesZantrex-3 is a diet supplement geared toward both men and women. This product incorporates active ingredients such as Caffeine (stimulant), Panax Ginseng (assists with proper blood flow), Kola Nut Extract (stimulant), Yerba mate (a stimulant for the nervous system) and Green Tea (helps the immune system and metabolic rates). Zantrex-3 is commonly available in nutrition stores and online. Like many other modern weight loss products, Zantrex-3 is recommended for daily use. This product is not offered with a money-back guarantee.

- There doesn't appear to be much clinical evidence offered supporting the effectiveness of Zantrex-3.
- Zantrex-3 does not appear to be sold with a money-back guarantee.
- The official Zantrex-3 website lacks convincing customer testimonials.
- No trial sample of Zantrex-3 is provided through the official website.
- In our opinion The website comes across like an infomercial, with little actual product info supplied.
ConclusionAlthough Zantrex-3 makes claims to effectively aid in the weight loss process, the primary ingredients listed for this supplement appear to be mostly stimulants. Unfortunately components like caffeine are known for pulling water from the user's body, which ultimately exhausts your metabolic system. On the bright side, Zantrex-3 can be easily purchased online and in stores. However, since this particular supplement does not come with a money-back guarantee, and no free trial samples are offered online, some consumers may turn the other cheek. Considering the wide array of dietary supplements currently available these days, it's wise to consult a physician before simply choosing one like Zantrex-3.
Zantrex Ingredients and Supplement Facts
Serving Per Container:
|Amount per Serving||% DV|
Other Ingredients: None
We researched Zantrex ingredients in order to give you the information you need.
Niacin, also known as vitamin B3, is important to overall health. It is one of the eight B vitamins needed for general health.
What Is It Supposed To Do?
Niacin, like all B vitamins, plays an important role in converting food to energy. Specifically, it can help create sex related hormones and can aid in the suppression of inflammation.
According to the University of Maryland Medical Center, niacin may play a role in the treatment of diabetes. In the article, they wrote, “Researchers have also looked at whether high-dose niacinamide might reduce the risk of type 1 diabetes in children at risk for the disease. One study found that it did. But another, larger study found it did not protect against developing type 1 diabetes. More research is needed.” However, later on, they also mentioned, “…niacin may also raise blood sugar levels, which is particularly dangerous for someone with diabetes.”
You may want to try Dietspotlight Burn, a weight-loss supplement that has four clinically tested ingredients, plus user reviews that show amazing results.
Yerba mate can be found in many weight-loss supplements. It is particularly popular in Brazil, Paraguay, and Argentina. It is also consumed as a tea.
What Is It Supposed To Do?
Yerba mate is usually consumed to treat fatigue, heart failure, low blood pressure, urinary tract infections, kidney stones, and obesity, based on ancient and current medicine.
According to a study published in Korean Association for Laboratory Animal Science: Laboratory Animal Research, “This study found that Yerba Mate extract has potent anti-obesity activity in vivo [in animals].” These tests were performed on mice, so effects on humans may be different. More research needs to be performed.
Guarana Seed Extract
Guarana is a plant that became popular after it became known that the Guarani tribe in the Amazon brewed it for a weight-loss drink. It can now be found in many supplements and medicines.
What Is It Supposed To Do?
Guarana seed extract is thought to help treat fatigue, obesity, low blood pressure, diarrhea, heart problems, fevers, headaches, and joint pain.
According to a study published in the Journal of Dietary Supplements, “We concluded that the weight stabilization and increased appetite that we observed in this study justify further studies of guarana in this [anorexic] patient population.” In this case, guarana was used, successfully, to increase weight and heighten appetite.

Zantrex Side Effects:
Zantrex Black has mixed feedback from users. Many people report side effects, which should raise red flags. Because you never know how your body may respond to a new supplement, you should take all risks into consideration.
Rapid heart rate
A number of users indicate that their heart started beating rapidly upon using this product. Rapid heart rate, or tachycardia, is problematic because it keeps blood from flowing properly throughout your body. Without this blood, your tissues and organs won’t function right. Signs of rapid heart rate include dizziness, shortness of breath, and chest pain.
What causes rapid heart rate?
High blood pressure, hyperthyroidism, tissue damage, and excessive alcohol use are common causes of rapid heart rate. 
Headaches can be very discomforting and make it hard to go about your day. Some headaches are mild. They create a sensation of tightness or pressure in your head. Others are more intense, like a stabbing or piercing. Serious headaches can even provoke dizziness and loss of balance. You may simultaneously experience sweating and malaise.
What causes headaches?
Conditions like concussion, glaucoma, and high blood pressure are known to cause headaches. Most headaches, however, are not serious. It may be that you haven’t been drinking enough water, getting enough sleep, or eating enough.
It’s not uncommon for you to become nauseous and bloated when you have stomach pain. In some cases, you can physically feel your stomach tighten up. You may also be suffering from fever and sweating. You get light-headed and physically weak.
What causes stomach pain?
Indigestion and pelvic inflammatory disease are among the top causes of stomach pain.  You may also have a food intolerance or allergy. Always check whether your food is spoiled. And be sure to wash fruits, vegetables, and meats. This reduces the chances of getting a stomach virus or bacteria.
Diarrhea can be very painful and uncomfortable. It makes you run to the bathroom every few minutes. Your stool is watery and liquid. Because of the constant bathroom trips, your rectum gets sore. The constant expulsion of liquid leaves you vulnerable to dehydration. Also, you might get weak because your body eliminates its nutrients.
What causes diarrhea?
Diarrhea may stem from a case of irritable bowel syndrome or food poisoning. It can also be a symptom of fever. Many stomach viruses and bacteria provoke diarrhea. Parasites can also cause diarrhea, but they’re less common in developed countries.
Not everyone who uses Zantrex Black experiences side effects. To be safe, you may want to consult with your doctor about the risks of using this product.
