There’s quite a buzz about Phentabz reviews, so we dug deep into the ingredients, side effects, scientific research and customer service. Additionally, we jumped into hundreds of consumer comments and reviews. We then condensed and summarized to give you the info you need.
What is Phentabz?
First off, Phentabz is a fat burner containing:
- DMAA 
The recommended dose is one capsule per day, not to exceed two capsules. The supplement supposedly assists with burning fat and weight-loss. One benefit of the capsule is ease of use.
The product was introduced in 2001 by Gentech Pharmaceuticals. The company also sells the supplement under the banner of Lexium International. You can purchase it on the official website. We do like that the company has been in business for more than 10 years but read on…

Ingredients Unsafe – “FDA Says Yes”
The first concern for us was Phentabz ingredients. “Caffeine  is considered a safe and efficient weight-loss supplement,” said our Research Editor. “But, when a diet pill contains a banned substance like DMAA, there could be an issue.”
According to the FDA, “DMAA, especially in combination with other ingredients such as caffeine, can be a health risk to consumers. Ingestion of DMAA can elevate blood pressure and lead to cardiovascular problems ranging from shortness of breath and tightening in the chest.”
It’s also important to note, “DMAA-containing dietary supplements are illegal , and their marketing violates the law. Based on the scientific information reviewed by FDA, DMAA is not a dietary ingredient.”
Phentabz Side Effects – “A Major Concern”
Based upon some customer comments, the adverse reactions with Phentabz RX can be severe. “I have not experienced weight loss yet, but there are side effects like feeling edgy and jittery and going to sleep at night has been difficult,” said a consumer.
“The only side effect was that it was making me jittery,” offered a dieter.
“I get these hot sweaty episodes with a heavy weight feeling on my chest, and it gets hard to breathe,” reported a user.
Our research shows that if an issue arises, like side effects, this could hinder long-term success. If Phentabz side effects does, in fact, cause adverse reactions, there is a problem.
The Science – “Is There Any Proof?”
While the official Phentabz customer reviews website makes the case that the supplement is an effective weight-loss pill, we can’t find any clinical studies speaking directly to the benefits of the ingredients, other than caffeine. We did locate several cases where the Food and Drug Administration has banned DMAA  from products. At DietSpotlight, finding science to back claims is critical. If there is no research, dieters should probably walk away .
What Users Are Saying
“I know you should try phentabz (it works better, but without all the jittery feelings I get from phentermine) … not cheap but I guess you get what you pay for… I tell all my friends to do serious research like I did”

“It has been three months since I stopped taking Phentemine and it seems that my weight has stabilized at only a few pounds more than what I weighed when I stopped taking it.”
The Bottom Line – Does Phentabz RX Work?
So here’s our final take. You might be thinking what’s the better option, Phentabz vs Phentermine, but we have some news for you. There are some favorable aspects of the product, like the longevity of the parent company and some positive customer comments, but we can’t get past our reservations because of the lack of clinical research supporting weight-loss claims. Plus, we’re concerned about the combination of ingredients, the potential for Phentabz side effects and the “F” Better Business Bureau rating.
If you’d like to see real results, we recommend going with a product that contains ingredients backed by published clinical research, with no warnings from the FDA and no side effects mentioned in any dieter review.
Among the best products we’ve seen this year is our product called Burn HD. The formula contains a four-ingredient proprietary blend. All clinically-tested with results commonly found in journals such as Obesity and The American Journal of Clinical Nutrition.
