The supplement claims to have ingredients which help to perform two essential functions: help you increase the mobility of fats while boosting the metabolism and reduces appetite while controlling the craving and motivation.

To confirm or deny the manufacturer claims about the product, we asked our research to have a deeper look into the ingredients and provide all the essential details about them. Additionally, we read out multiple customers reviews and feedbacks to see how it worked for them and thereby we shortened all other findings to give you a scientific overview of the product so you'd make a better decision if this product is suitable for you or not.

Let's discuss what we discovered…

What is PhenTabz?

PhenTabz is a dietary supplement that claims to help you shed down unwanted fats while promoting an increased metabolic rate. According to the company, the supplement contains ingredients which are supposed to aid in suppressing appetite so you can control your hunger pangs and promote effective weight loss.

According to the official website, PhenTabz should be taken only if your health care expert approves it for you. However, the supplement isn't a prescription based supplement and you can purchase it directly from the official website.

The supplement comes in the form of capsules and suitable both for men and women.

PhenTabz Ingredients Analysis

PhenTabz ingredients include:

  • Caffeine anhydrous
  • Synephrine HCL
  • Octopamine HCL

Other ingredients include microcrystalline cellulose, stearic acid, dicalcium phosphate, croscarmellose sodium, sugar, magnesium stearate, silicon dioxide, pharmaceutical glaze, com starch and FD&C blue #1.


Caffeine is one of the most commonly consumed psychoactive substance around the world – and for a good reason. It helps in boosting your metabolism that makes it easier for you to lose weight so you can eat more with minimum chances for further weight gain.

Studies have shown that caffeine can increase the RMR (resting metabolic rate) by 3% to 11% with larger dosages (1, 2).

However, the effect of caffeine is short-term. After a while, people become tolerant to its effect and it doesn't work further.

According to Katherine Zeratsky, R.D., L.D. from MayoClinic, there's no sound evidence that could prove that increased consumption of caffeine promotes significant or permanent weight loss.


Also known as “bitter orange” has been shown to cause modest weight loss when paired with a sensible diet and effective exercise regimen. However, it's probably doesn't worth the risk to use bitter orange due to its potentially dangerous side effects.

Bitter orange contains synephrine that is very similar to the substance (ephedra), banned by the FDA after reported for various serious health problems. That said, people suffered from a stroke and heart attack when used bitter orange alone or in combination with other stimulants such as caffeine.

Brent A. Bauer, M.D from MayoClinic advised checking with your doctor before taking any herbal supplements.

Unfortunately, PhenTabz supplement contains both of these substances (bitter orange and caffeine) as main ingredients so there are risks of experiencing potentially dangerous side effects.


Octopamine is a metabolite of synephrine which is thought have minor fat-burning properties. However, there is no human study found about this substance that could this support its direct fat burning claim, states

Octopamine is banned by WADA (World Anti-Doping Agency) due to its stimulatory properties.

Customers Reviews

We found many customers reviews and testimonials about this product. Here is what real customers saying about PhenTabz:

I've taken this for several days and it has not decreased my appetite so far. I've not experienced weight loss yet but there're side effects like feeling edgy and jittery and going to sleep at night has been difficult.
I've been taking PhenTabz RX and have had increased energy and moderate weight loss. I only take one tablet early in the morning because I can’t sleep at night when I take two. My question is, has anyone developed kidney stones while taking it?

“I had that chocolate shake almost every morning for breakfast and still dropped 3 dress sizes.”
