Zantrex-3 is a thermogenic weight loss pill that claims to be 546% more effective than Americans leading ephedra based pill. The company adds that caffeine plays a big role in making sure effects are felt.
The brand also suggests it can provide a high amount of energy. Diet and exercise are required, and they do mention that results may vary. There isn’t much information provided by the manufactures as far as what can be gained. They do add that people taking this brand lost around 11.2 pounds without having to include diet and exercise. So is there actually any proof to all this? What kind of an effect does this stimulant heavy brand have? To determine what the truth is, you can read this comprehensive review of Zantrene-3.

Trimethylxanthine: The chemical name for caffeine. Zantrex-3 has 300 mg worth per serving. It’s recommended by medical sites to get just 400 mg a day for the average person to avoid potential extreme side effects. Caffeine in any amount can cause side effects in certain people that include:
Damiana Leaf: Leaves used as an aphrodisiac and physical aid. There’s not enough evidence to suggest if it’s actually useful. It can cause serious side effects such as convulsions and symptoms similar to rabies.
No long term studies have gone into showing what kind of an effect is possible.
Yerba Mate Leaf: Plant brewed into a tea. It contains caffeine and other compounds. It has the same kind of side effects that come from caffeine since it has a high amount, more so than other teas.
Schizonepeta Flower Extract: Herb used in Asian medicine as an anti-inflammatory. It’s only been studied in vitro instead of in humans. It’s unknown if there’s any effect on humans.
Rhodiola Crenulata Root Extract: A plant used to improve learning and to protect cells from damage. It’s not been well studied and Web MD mentions there:
“isn’t enough scientific evidence”
It has also not been tested in long term studies, so it’s unknown what kind of an effect it may have.
American Ginseng: Herb that is considered an endangered species in America. It’s claimed to help regulate blood sugar. Its only been tested for short periods, it may have long term negative health effects. Possible side effects can include:
Maca: Plant grown in Peru that has many claimed effects such as being an aphrodisiac, providing energy, improving immune function, and much more. Due to it being a cash crop in Peru, many studies come from that region. Not enough studies have been performed to show if there’s any effect.
Some argue there’s a bias in these studies since they’re often published in Peru where it’s a large source of money.
FD&C Blue #1: Synthetic dye that has no nutritional value. It’s known to cause allergic reactions similar to asthma in certain people. The FDA sent a warning which mentioned that people who ate this dye suffered from side effects. According to them, there have been:
“several reports of toxicity, including death”
They also reported symptoms of discoloration in the stool and urine, ill patients and metabolic disorders. People were hospitalized causing the FDA to take notice and send warning letters.
6 of the ingredients are caffeine sources, some of which are teas that can be purchased for cheaper such as Yerba Mate, Green tea, and Black tea.
The other additives have either been poorly tested, or they are known to cause potential side effects.
Overall, the nutritional value is lacking. 7 other ingredients are only added to provide texture, color, or to make the pill easier to swallow. They offer no weight loss benefits. This brand has a lot of caffeine added to it which is known to produce unwanted side effects.
It relies heavily on caffeine which is where the thermogenic response and increase in energy are meant to come from. However, there are cheaper forms to get caffeine. Caffeine is also not long lasting; the body adapts and reduces any of the possible weight loss benefits.
An 84 capsule bottle is sold by the manufacturer for $29.99, and it’s advised to limit oneself to 6 capsules a day. Therefore the daily price provided in one bottle is:
$29.99/14= $2.14 for a daily serving.
It’s expensive for what’s essentially a mixture of different caffeine heavy ingredients with added unproven additives such as Maca, American Ginseng, and Schinozepeta. These ingredients either fail to have any long term studies, they’ve not been tested in humans, or they have conflicting reports.
The company mentions that it outperforms the number 1 selling Ephedra based pill. Ephedra is banned in the US, although extracts are available which aren’t as powerful.
They mention that in 6 weeks people who took Zantrex-3 lost 11.2 pounds more than the placebo group. They also mention that this occurred:
“without having to follow and prescribed diet plan”
However, the link to this study is never published. It’s unknown exactly what went into this clinical review. Sometimes studies will be biased and it’s important to be able to look over this reported proof.
Without seeing the exact details of these studies its unknown if what they are saying is true. It’s also not known if the company funded this study, this can also lead to a bias in positive claims.
Also, the high amount of caffeine included in Zantrex-3 is known to cause a possible change in metabolism. However, caffeine only lasts for a short period, and then it loses any of its positive effects except sleep deprivation. So it’s unknown what would happen with long term use of this brand.
Overall, since they fail to provide their clinical study, it cannot be trusted that it was unbiased or under ideal circumstances.
Clinical Study on Zantrex-3
A study published on the US National Library of Medicine was performed on a once healthy 38 year old woman.
She never had a history of seizures or past illnesses. Suddenly while taking this supplement she started experienced blurred vision, seizures, and other symptoms in just a month long intake of Zantrex-3.
After she stopped taking this pill she no longer had any seizures. She also had regular results on her MRI and EEG.
The study concluded that there was a:
“Potential toxicity of caffeine”
This all came through use of Zantrene-3. Similarly, customer opinions of this brand have been largely negative with some having to be hospitalized.

The company fails to provide much information about itself. There is an ongoing lawsuit from a person claiming to have suffered injuries from their supplements. The details of the case aren’t known however.
Most of the reviews available online are negative. Here’s what the average customer has to say:
“felt like my heart was going to explode”
“I had trouble with nausea and stomach discomfort”
“Didn’t lose any weight but it helped me poop a lot”
“this garbage has done nothing but put me in the hospital”
Overwhelmingly people have complained about serious side effects. A few people report being hospitalized as well as experiencing crippling anxiety and rapid heart rate.
Many mention they took just one pill and they still had difficult symptoms. People who were never sensitive to caffeine also reported that they couldn’t handle the rapid heart rate and feelings of anxiety.
Some key details that were discovered about Zantrex-3 include:
The vast majority of customers mention that they couldn’t deal with the tremendous side effects. Many warn customers to avoid this brand since it hospitalized some and caused other extreme issues.
The brand is also heavily featuring caffeine laden ingredients, many of which can be bought for much cheaper on their own. The brand also advises a limit of 6 pills which offers 900 mg of caffeine; this is more than double the advised daily limit.
