Losing weight has become more than just a fitness goal. More than a new year’s resolution and an item on your bucket list, weight loss itself has produced an industry on its own, with many companies mass-producing popular fat burners left and right.

With just about every bottle describing itself as the best and most effective when it comes to weight loss, how can you tell which one is real and which one is just there to make a quick buck?

The people at Wolfson Berg Limited claim to simplify the choice by introducing PhenQ.

The company claims PhenQ not only suppresses appetite, but also sparks your fat-burning processes. They say this allows you to have a holistic fat-burning experience.

Is PhenQ the fat burner for you? Let’s find out.

Who Makes It?

Wolfson Berg Limited is the company behind PhenQ. They have over a decade of experience in the industry and have become a trusted name in the supplement niche (1).

They’re proud to say each supplement is produced in an FDA-approved facility, and each formula makes use of ingredients that have been shown to work for weight loss.

Marketing Claims Made

Wolfson Berg Limited has made the following claims about PhenQ:

  • Burn stored fat: PhenQ is a fat burner, so to not have this claim would be ludicrous. However, each product has different ways of defining what fat burning really is. Judging with how PhenQ is formulated, the formula seems to rely on offering a thermogenic boost paired with appetite suppressing benefits.
  • Suppress your appetite: The ingredients known to suppress appetite in PhenQ are chromium picolinate and nopal. The dosages for both ingredients are lower than expected, so we’re not sure just how much suppressing PhenQ is capable of.
  • Block fat production: Only one ingredient has fat-binding properties and that’s nopal. We already discussed how low dosed it is, so we’re almost sure it won’t have any major effects on blocking fat storage.
  • Improve mood and energy levels: Caffeine’s known to have a great effect on energy and mood levels, but we also have to acknowledge that the effects are offered in spikes and makes you prone to something called a caffeine crash or simply a crash. When you crash, it’s when your energy plummets all too suddenly, causing you to feel suddenly tired.

What’s in it?

Let’s take a look at what’s inside PhenQ:

  • Calcium Carbonate: Calcium carbonate is an ingredient you don’t see in many fat burners. We were completely surprised when we saw it too. However, as it happens there is actual evidence suggesting this chalk ingredient and a common bulking agent is capable of promoting a bit of weight loss. However, the effects seem to be minimal though there is potential for better weight loss if taken for longer than 24 weeks (2). The 625 mg dosage is really good considering studies made use of 1 gram in a single-ingredient formula. We also think this is quite a strategic move given how cheap calcium carbonate is compared to the rest of the ingredients in this formula.
  • Caffeine Anhydrous: We have 150 mg per serving of the world’s most consumed drug. Being a stimulant, caffeine anhydrous functions on both energy and fat burning mechanism (3). The dosage is equivalent to about one and a half cup of coffee.
  • L-Carnitine Fumarate: We all recognize L-Carnitine as one of the most popular fat burners in the early 2000s. It has been added in just about every beverage and weight loss powder and it’s still relevant in today’s fat-burning formulas. This amino acid funnels fatty acids across the cellular membrane of the mitochondria and converts those fatty acids into cellular energy. Scientists do note that on its own, L-Carnitine is ineffective and must be paired with exercise (4). The dose we have L-Carnitine is too small for it to work, as studies, as well as many fat-burning formulas, add at least 250 mg for some fat burning function.
  • a-Lacys Reset: This is a rare addition and the first time we’ve encountered it. After doing some research, we found that a-Lacys Reset is a branded and patented combination of alpha-lipoic acid and cysteine. The combination promotes absorption as well as focus on alpha-lipoic acid’s small, short-term weight loss benefits (5).
  • Nopal: Nopal is a fiber derived from the nopal cactus. As with all types of fiber, nopal helps with weight loss by suppressing our appetite which helps delay the onset of hunger. One study notes cactus fiber also helps bind fat to feces excretion as well as reduce dietary fat absorption (6).
  • Capsicum Extract: Capsicum is the one compound that gives you that hot sensation when eating peppers. That hot and sweaty feeling is actually the body burning fat to raise the temperature and produce sweat aka an attempt to cool you down. This process is called thermogenesis and is the core of many fat burning ingredients in the supplement industry (7).
  • Piperine Extract: Piperine extract works as a bioavailability booster, allowing each ingredient to be absorbed at a more efficient rate. The addition of piperine to any supplement is essential, as studies note it exerts absorption benefits to every ingredient in the blend it’s mixed with (8).
  • Chromium Picolinate: Chromium is a mineral that provides an appetite suppressant benefit. It mainly works on balancing blood sugar levels which help regulate our appetite, as blood sugar spikes and crashes are one of the factors involved in feeling hungry (9). Being so low in the formula ladder is normal for this ingredient. It works in small doses of up to 200 mcg or micrograms. For context, 1 mg is equal to 1000 mcg.

PhenQ Supplement Facts Label

Phenq Supplement Facts


For the most part, PhenQ’s benefits on weight loss seem to stem from its thermogenic and appetite suppressing properties.

Calcium Carbonate is the wild card in this formula, but we think it’s a bit weak to be the driving force of Phen Q’s fat-burning formula. The combination of caffeine, L-Carnitine, and capsicum should provide a good thermogenic boost.

Piperine’s bioavailability boosting properties should also exert an effect on nopal and chromium for the appetite suppressing benefit.


While the formula is quite weak overall in terms of dosing, and with it the chances of having side effects minimal, we’re not yet sure about the effects of taking calcium carbonate in capsule form. So, it would be wise to closely follow the serving suggestions before trying to increase the dosage.

We always recommend you speak with a doctor before taking any supplements.

How to Take It

The label is quite straightforward when it comes to directions for use. All you have to do is take one capsule with breakfast and one more capsule with lunch, making PhenQ a two-capsules-a-day supplement. This makes the 60-capsule bottle last 30 days.


As capsules, it shouldn’t have any real taste or flavor at all. The label we saw also didn’t specify any ingredients that could impart taste.

Number of Servings

One container provides 60 servings which, if taken twice a day, lasts for 30 days.

PhenQ vs Phen375

PhenQ’s rival in the industry is a similarly named fat burner called Phen375.

Both supplements contain calcium carbonate, chromium, L-Carnitine, caffeine, and cayenne in their formula. The difference is Phen375 contains more recognized fat burners than PhenQ. These are coleus forskohlii and citrus aurantium which contains synephrine.

From the context of an overall metabolic boost, Phen375 has the upper hand given the potency of the ingredients in the formula as well as the addition of synephrine which just so happens to be synergistic with caffeine. However, PhenQ has relatively better dosing than Phen375 on a per capsule basis.

So, you can choose whether to go for the overall metabolic boost or the combination of a decent metabolic boost paired with some appetite suppressing benefits.

Customer Feedback

Most online reviews on PhenQ seem to fall on the positive side. Many review sites recommend PhenQ, with many rating it at least 4 stars out of 5.

Some consumers do note that PhenQ didn’t work for them with regards to energy boosting as well as appetite. We can’t blame them since the dosing for the ingredients meant to do those aren’t exactly in their most potent.

Bottom Line

We dug deep into PhenQ and analyzed each ingredient as well as how they work together. We have to conclude that PhenQ is an “okay” fat burner.

Given the small serving size, it’s not hard to see why PhenQ isn’t as potent as it wants you to think. And when it comes to capsules, you have to make sure you have room for each ingredient you add.

PhenQ’s biggest error is including so many ingredients in a small serving size that resulted to less than stellar potency across the entire formula. Even with the help of piperine, we’re not entirely confident about its fat-burning potential unless the user takes it upon themselves to double the recommended serving.

We also think the pricing for PhenQ is absurdly high. Half the formula is mostly chalk, and the remaining ingredients aren’t exactly dosed appropriately.

We hope this review helps you make an informed decision, whichever route you take.
