Today, it seems like there’s one fat burner out there per every pound people need to lose…in other words, a boatload of fat burners and weight management supplements!

And for the most part, they all contain generally the same ingredients: green tea, cayenne, caffeine, etc. But there are a few supplements that stand out from the rest due to their unique ingredients and optimal dosages.

And in this review, we’ll go over one such product called Phenocal to see if it’s one of the better fat-loss supplements out there. 

Ready to learn more about this weight control supplement? Let’s jump into this Phenocal review!


About Phenocal 

Phenocal is supposedly the #1 rated all-natural weight loss product (at least that’s what they say). 

It is featured by what they call “thermokinetic weight loss technology”, helping users to lose weight in a safe, natural, and healthy manner. 

In fact, Phenocal is specifically designed to complement your diet and exercise regimen to jumpstart the fat-loss process and help you lose weight steadily over time. 

Sure, it includes key ingredients like green tea, chromium, and B-complex vitamins, but it also has unique ingredients such as Umbrella arum root powder, mate leaf extract, and evodiamine.

Altogether, these ingredients are supposed to rev up your fat loss so you can get that rocking beach body you’ve always wanted (or maybe even had when you were younger? Oh, the days…)

Phenocal Benefits

Phenocal hoists up some pretty bold claims regarding Phenocal. 

Specifically, Phenocal is advertised to:

  • Promote Rapid Weight Loss
  • Rev up Metabolism
  • Increase Energy Levels
  • Suppress Appetite
  • Support Healthy Insulin Levels
  • Target Stubborn Body Fat

And they say that noticeable results are GUARANTEED for anyone who tries it.

Rapid Weight Loss

Phenocal is designed to work with your body to help shed off the pounds naturally, so you can experience much greater weight loss compared to diet and exercise only. 

Rev Up Metabolism

One of the ways Phenocal is designed to work is by revving up your metabolism and kicking thermogenesis into high gear with ingredients such as green tea extract and hoodia gordonni extract.

Increase Energy Levels

Phenocal is also advertised to increase energy levels, mainly with their whopping dose of B-complex vitamins and chocolate bean extract. In turn, you can have more energy while dieting, and to help you get through your workouts for more intense results.

Suppress Appetite

Diet is likely the main factor in weight loss, and Phenocal aims to capitalize on this by suppressing your appetite and curbing cravings with ingredients like fucoidan, so you have a better chance of staying in a deficit.

Support Healthy Insulin Levels

Phenocal is also promoted to support healthy insulin levels thanks to ingredients such as chromium picolinate. What this may mean is a more balanced metabolic profile and an easier time losing weight. 

Target Stubborn Body Fat

When people want to lose weight, there are often a few key stubborn areas (mainly the belly, hips, and chest). And Phenocal is advertised to target these stubborn areas so you can start looking better, quicker.

These claims are all mouth-watering for anyone looking to drop the pounds. But is Phenocal actually a phenomenal fat-loss supplement? Read on to find out!

Phenocal Proprietary Blend

As mentioned, the PHenocal Proprietary Blend contains many different ingredients. 

Green Tea Leaf

Phenocal has green tea leaf extract and green tea leaf powder, but we’ll group them together since they have the same effects. 

Green tea is most known for its rich catechin content (such as EGCG). And it may be able to slightly increase thermogenesis, fat metabolism, and energy expenditure. 

You can find it in many other fat burners too, such as Triple-Tea Fat Burner.

Recommended Dose: 200 to 400mg

Umbrella Arum Root

Umbrealla arum root is known for its glucomannan content, which is a type of soluble fiber. Glucomannan may increase feelings of fullness by creating a gel-like substance in the stomach. This also delays the absorption of fats and sugars too. 

Some research shows glucomannan is associated with modest weight/fat loss.


Tyrosine is an amino acid known for its ability to boost serotonin, dopamine, and norepinephrine. And these stimulatory effects may make it effective for reducing appetite and increasing weight loss. But there’s not much research, other than a study showing tyrosine alongside other ingredients led to a slight reduction in fat loss. 

Chocolate Bean

Chocolate (cocoa/cacao) bean extract is rich in polyphenols, which have an influence on many bodily processes, including metabolism. Some research suggests that cocoa bean extract has favorable effects on fat metabolism, and it may help with blood pressure, cholesterol, and other metabolic markers, but more research is needed. 

Hoodia Gordonii

Hoodia gordonii is a plant known for its compound pregnane glycoside P57, which has been shown to suppress appetite and may aid weight loss. However, current evidence shows that it may have some serious adverse effects when taken at high doses.


Garcinia fruit has been around in supplements ever since fat-loss products were made. Extracts from this fruit are said to improve weight loss in a number of ways. 

Hydroxycitric acid in garcinia may be able to inhibit enzymes involved in fat and carbohydrate metabolism. Plus, garcinia may be able to increase serotonin in the brain, leading to appetite suppression. 

Recommended Dose: 1,500 to 3,000mg

Tryptophan and 5-HTP

Also included in Phenocal are tryptophan and 5-HTP. Tryptophan in the diet is needed to make 5-HTP, which then is converted into serotonin. And it’s speculated that increased serotonin would lead to greater feelings of fullness and reduced appetite. However, this combo doesn’t appear to really do much for weight loss.

Mate Leaf

Mate (yerba mate) leaf extract is another widely studied fat-loss ingredient. Certain compounds in mate have been shown to have antioxidant effects, while also increasing energy expenditure and decreasing blood lipids (fats). It may also have a blood sugar-lowering effect, especially in people with type 2 diabetes. Plus, it can decrease some hunger hormones and delay stomach emptying. Overall, mate appears decently effective for fat loss and weight loss. 

Coleus forskohlii

Coleus forskohlii is an Indian Ayurvedic plant known for its forskolin content, which can ultimately influence cAMP production, which in turn has an effect on many metabolic processes. Some research shows that Coleus forskohlii can trigger thermogenesis, reduce food intake, and reduce fat accumulation, which makes it pretty solid as an anti-obesity compound.


CLA is a type of fatty acid that may be able to reduce energy intake by increasing feelings of fullness. And it also may be able to increase lipolysis (fat breakdown), but more evidence is needed.

3,000 to 6,000mg


Evodiamine is thought to work somewhat similarly to capsaicin, mainly by increasing thermogenesis and reducing the number of triglycerides, cholesterol, and fatty acids. Small amounts of research show that it might be helpful for triggering fat loss. 

B-Phenylethylamine HCl

Phenylethylamine is a stimulant ingredient that can increase energy expenditure and enhance lipolysis, largely due to its effects on the beta-adrenergic receptors. 

Now, let’s get to the other ingredients. 

Vitamin D

Vitamin D is basically a hormone involved in brain, heart, and bone health, as well as mood and energy levels. However, vitamin D supplementation is unproven to offer any weight loss benefits.

B-Complex Vitamins

Phenocal includes really high doses of the B-complex vitamins, including a notable 2,000% DV of B12 and over 800% DV of thiamine. 

B-complex vitamins are most known for helping to convert food into energy and similar metabolic processes. They also are important for brain health and function. 

So, taking in more B vitamins could potentially increase metabolism, but it’s unclear if it’ll really lead to weight loss. 

Chromium Picolinate

Chromium picolinate is involved in carbohydrate, fat, and protein metabolism. Plus, it also improves insulin sensitivity and can help reduce blood glucose. Some research shows that chromium supplementation can help maintain lean body mass while losing weight, but the effects aren’t anything huge. 

Recommended Dose: 200 to 400mcg


Fucoxanthin extract comes from brown seaweeds. Some research shows that fucoxanthin supplementation can reduce triglycerides and cholesterol, while improving fat metabolism and even increasing satiety. 


The last ingredient in Phenocal is BioPerine, which is mostly known for its ability to enhance the absorption and bioavailability of other ingredients, helping to increase their effectiveness. 

Recommended Dose: 5 to 15mg

Does Phenocal Work?

Phenocal should likely be an effective fat-loss supplement. 

phenocal does it work

It contains many well-researched ingredients known to positively affect weight and fat loss in a number of ways. 

The ingredients in Phenocal have been shown to improve lipolysis; increase thermogenesis, reduce triglycerides, cholesterol, and fatty acids; increase feelings of fullness; and suppress appetite. 

As a result, Phenocal may work on many different mechanisms to help you lose weight and fat. 

However, most of the ingredients are included in a blend, so it’s unclear how much of each ingredient is in there; this really limits the overall effectiveness that can be claimed. 

That’s why it may be better to get a fat burner that lists out all of its ingredients, such as Hunter Burn.

Also, it’s important to remember that most of the studies that showed benefits still didn’t have that crazy of results (more on that below). 

Claims vs. Reality

When looking at any supplement, it’s important to be realistic. So, while Phenocal probably works, I wouldn’t expect any massive weight loss or huge drops in body fat. 

Most of the ingredients in here, even the really well-known ones (green tea, garcinia, mate, chromium, etc.) usually don’t lead to more than a few extra pounds lost over several weeks compared to a placebo. 

So, Phenocal likely still will help you with metabolism, weight loss, hunger, and fat reduction, but just be realistic about the effects. 

And most likely, it’ll take at least several weeks before you notice anything significant. 

Who is Phenocal Best For?

Phenocal is best for people who want a boost alongside diet and exercise to help them lose a few extra pounds and aid overall metabolism.

  • Nausea, bloating, upset stomach, and other digestive symptoms
  • Headache

  • Possible liver damage

Phenocal is made in an FDA-inspected facility and produced under GMP standards. Plus, it’s laboratory tested for purity and potency.

Final Verdict: Phenocal Review

Phenocal for the most part has well-researched ingredients, although we don’t like that most of them are included in a proprietary blend. With that being said, given the overall ingredient quality, and fair price, Phenocal is a decent fat burner worth looking into if you want to try to shed a few extra pounds. It’s no miracle worker, but could be that little boost you need.
