There’s quite a buzz about Phentabz, 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 caffeine, DMAA and synephrine. 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…
I…wasn’t hungry really at all. However!!!! I felt really edgy.
Ingredients Unsafe – “FDA Says Yes”
The first concern for us was Phentabz ingredients. “Caffeine is considered a safe and effective 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.”

Side Effects – “A Major Concern”
Based upon some customer comments, the adverse reactions with Phentabz 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 does in fact cause adverse reactions, there is a problem.
The Science – “Is There Any Proof?”
While the official Phentabz 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.

The Bottom Line – Does Phentabz Work?
So, what’s our final take on Phentabz? 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, 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 in 2016 is one called Leptigen. The formula contains a four-ingredient proprietary blend, shown in published scientific research to help enhance fat loss and ignite metabolism. There’s no talk of negative side effects and customer reviews state people are seeing exceptional results.
Also, the makers of Leptigen are confident in the supplement, so they’re offering a Special Trial Offer, which is an excellent choice.

What You Should Know

PhenTabz is a weight loss supplement that claims the only side effects from taking the supplement are increased energy and faster weight loss. The official website looks like a website for a prescription drug, which is exactly what the company is going for. According to the PhenTabz description, the supplement works like Phentermine, the prescription weight loss drug, but dieters don’t need a prescription. There are three products described on the website: PhenTabz, PhenTabz Teen and PhenTabz RX. None of these products lists ingredients used to promote weight loss.
List of Ingredients
We looked through every link on the PhenTabz website and not one ingredient is listed for any of the three formulas Gentech Pharmaceuticals wants dieters to trust. There is mention of a proprietary blend in the FAQs section of the website, but the ingredients present in that blend are not listed.
Weight loss supplement companies have a responsibility to list all ingredients so dieters can review ingredients and choose whether or not they want to try a product. Moreover, some natural ingredients are contra-indicated when prescription medications are taken. Gentech Pharmaceuticals expects the dieter to just choose PhenTabz on faith that none of the ingredients cause negative side effects and that’s not a responsible choice for dieters to make.
The blatant use of medical images and the extension “RX” is something we consistently tell dieters to avoid. Diet supplements are not medical supplements. Prescription medications are reviewed and approved by the Food and Drug Administration. The same cannot be said for weight loss supplements.
We are also concerned that Gentech Pharmaceuticals markets a diet supplement for teens. Ingredients commonly used in diet supplements are not tested on teens and thus should not be considered healthy or safe for teen consumption. Of course, we are assuming there are ingredients other than those found in common vitamin supplements because the company does not list ingredients.

- No ingredients are listed for any of the PhenTabz products.
- The marketing push is clearly toward dieters looking for phentermine without a prescription.
- There is a product aimed at teens.
The first thing we look for when reviewing a diet supplement is an ingredient list. If a company is not willing to reveal the ingredients used in the formula, they are not willing to earn the trust of the consumer. We can only assume Gentech Pharmaceuticals is hiding something by not publishing the complete list of ingredients for PhenTabz, PhenTabz RX and PhenTabz Teen.
