I’ve been a big fan of Mike Matthews and the Legion Athletics range of dietary supplement products he has created.

But we’re not in the habit of just accepting fat burners at face value without putting them through our usual testing process.

We’ve done this for over 50 weight loss products, and unfortunately, most of them fall way short of the mark.

So, as part of this Legion Phoenix review, we’ll look at ingredients, how well it actually works, and the all-important side effects.

What Is Legion Phoenix?

Holding a Legion Phoenix fat burner product

Legion Phoenix is a caffeine-free fat burner that claims to have clinically effective ingredients.  And it’s this statement that we put under the watchful eye of our dietitian.

The way Phoenix aims to work is to help people eat less and burn more calories throughout the day. How is this achieved?

Apparently, the chosen ingredients in this product act as an appetite suppressant, as well as a booster for your basal metabolic rate.

In theory, the result should be a more effective fat loss program where you could get to your goals faster.

Now, I will say right here that these products only work when combined with a healthy diet and exercise routine. There simply isn’t a way to lose weight while sitting on the couch and stuffing your face with donuts.


The question is, though, do the ingredients live up to the great claims being made?

Let’s have a look.

Legion Phoenix Ingredients

Supplement Facts of Legion Phoenix

The first thing we wanted to do was verify the claims that all the Legion Phoenix ingredients were actually scientifically proven.

For this, we got some help from our dietitian friend Susan, who gave us some great insights. Not only did she look at the ingredients, but also if the dosage per serving might be effective.

1 - Synephrine

Synephrine is extracted mainly from citrus fruits. It’s commonly used in diet pills because of its reported thermogenic properties.

From a fat loss perspective, there is one study, in particular, that was able to tie synephrine to fat oxidation [1]. However, the same study was using doses that were four times higher than what this supplement provides per day.

2 - Coleus Forskohlii

This Indian herb, Coleus Forskohlii, has been used for centuries in traditional medicine. But some studies have also been able to show clinical effects on abdominal fat.

From our dietitian's feedback, this could be a good ingredient, but don’t expect miracles. The studies so far were mainly done with mildly overweight and obese people [2].

3 - Green Tea Extract

Green Tea Extract

Green tea extract contains a substance called epigallocatechin gallate (EGCG).

According to some studies, this is what might be giving green tea extract its fat burning properties by increasing your resting metabolic rate [3].

Aside from its ability to burn fat, the added bonus of green tea extract is that it could help you detox and remove some free radicals to improve your overall health as well.

Green tea extract is made from unoxidized leaves and is one of the least processed types of tea. It, therefore, contains the most antioxidants and beneficial polyphenols.

- Debra Rose Wilson, Associate Professor and Holistic Healthcare Practitioner.

4 - Naringenin

This is another extract from citrus fruits, which some researchers believe may impact fat oxidation thus leading to less body fat [4]. One thing I would note, though, is that there are some conflicting research and a few outstanding questions on how well it actually works.

Some scientists suggest that the potential to burn fat may be limited with more benefits coming from the antioxidants.

5 - 5-HTP


This is not the most common ingredient in diet supplements.

However, there is some evidence that it could help in making you feel full and avoid those hunger cravings.

Based on some online reviews, quite a few people did mention that taking Legion supplement does seem to suppress your appetite.

6 - L-Tyrosine

L-tyrosine seems to be more common in nootropics as it may be tied to releasing common neurotransmitters. By giving you a brain boost, it may help to keep you motivated in your diet and workout efforts.

Tyrosine supplies what your body needs to generate three important neurotransmitters: dopamine, norepinephrine, and adrenaline. Studies show tyrosine might also help with mood and help people enjoy life.

Capsules vs. Powder

Many dietary supplements, including fat burners come in powder form that you mix into food or water. However, for some folks, that’s not overly convenient.

Usually, those powder supplements are meant to be taken once a day. But that might mean that you won’t get the full benefits spread out over the day.

A more convenient way is the capsules that the Legion Phoenix product comes in. You could simply keep them in your bag and have them available throughout the day.

And you won’t have to worry about whether the flavor is nice, as some of these products fall a bit short when it comes to taste.

Pros and Cons

legion phoenix thumb

What we liked most about this product is that it doesn’t contain caffeine. While caffeine is a known thermogenic, it can make some people feel a bit jittery.

Quite a few folks mentioned that they found it worked well to suppress their appetite between meals to reduce their food intake.

And the money-back guarantee does give you peace of mind that if it doesn’t work for you, it won’t be a wasted investment.

We also found a few online reviews where people said they had some side effects on their stomach, like cramping.

if you don't mind having quite a bit of caffeine, you might want to check out our review of Burn XT.

  • As a caffeine free option, it should be more suitable for taking later in the day.
  • Comes with a money-back guarantee
  • You’ll have to remember to swallow five capsules daily
  • Some of the ingredients are not really proven to work
  • Mixed reports from users about the effects on stored body fat

The main downside is that our dietitian poked some holes in the claims made by the company. Some of the scientific research are inconclusive.

You’ll also need to set a reminder or get into the habit of taking Phoenix throughout the day for a total of three capsules per day to spread out the fat burning properties and effects.

Legion Phoenix Side Effects

side effects

One thing we’ve often encountered with fat burners is that folks tend to feel bloated and crampy.

This may be reduced by taking the capsules with food. But if you need a product to help you with longer fasting times, then that kind of defeats the purpose.

My own experience confirmed some of the feedback from our clients, as well.

When you take Phoenix, you could have a higher chance of feeling bloated and gassy. I would certainly not advise taking all three capsules in one go on an empty stomach.

Where Can You Buy Legion Phoenix?

buyers guide image

There are only two places I would recommend buying this product.

The first place is on the official website of Legion Athletics, which is generally the safest place. The other option is to order it from Amazon, as this also should give you a sense of security that you’ll get the real deal.

In recent years, there have been a lot more reports of counterfeit products available on different marketplaces online.

Not only would these likely have no effect at all, but you could also end up buying something that could do some harm.

Legion Phoenix Price

A bottle of Phoenix costs about $40, which is good for a month with the recommended daily dosage of 5 pills. You should take them twice throughout the day, with 3 pills before breakfast and 2 before lunch or dinner.

As ingredients of similar products vary, it's hard to compare if this is cheaper than others, but generally, taking Phoenix costs only $1.33 a day. I can say that it is reasonably priced, as one of the higher quality ones average at $2 a day.

Legion Phoenix Reviews

hands on phone

To give you an idea of why we’re not entirely convinced of it, let me summarize a few customer reviews.

After using it every day for 6 weeks, he found that a lot of his food cravings were gone. This helped him reduce calories from random snacks.


- Mike from NY

This is one of the customers who found that with the full serving, he had some side effects and felt quite bloated.


- Jason from Alberta

She has been using Legion supplements for a while and has adapted the dosage to her needs. The main attraction for her is that there are no caffeine jitters.


- Allison from Miami

She did note that her appetite was contained for longer fasting periods. But she didn’t find it boosted her metabolic rate enough to notice any changes in her weight.


- Gemma from San Diego


When Should You Take Legion Phoenix?

You should take Phoenix ideally first thing in the morning with breakfast. Like any other dietary supplement, you can take the remaining pills within the day to spread out the effects and reduce the chance of negative effects.

How Do You Take Legion Phoenix?

You take Legion Phoenix as three capsules first thing in the morning with breakfast. Because Phoenix doesn’t contain caffeine, it should be OK to time it later in the day and not have a sleepless night.

What’s the Recommended Legion Phoenix Dose?

The recommended Legion Phoenix dose is three capsules per day. However, you should spread these out and not swallow them all in one go.

Is Legion Phoenix legit?

Yes, Legion Phoenix is legit, but some of the ingredients are not in a strong enough dose to provide desirable effects. There are other products that have shown better results that are also formulated specifically for men and women.

See our recommended fat burners for females and for males.

How Do Fat Burners Work?

There are four main ways these pills burn body fat quickly. The most common way is suppressing appetite which you can experience with Phoenix. It basically controls your hunger better to help you "eat less" and avoid snacking, as it keeps you full and satiated longer.

Another way is by increasing thermogenesis to help your body burn more body fat and calories than expected by increasing the body's metabolic rate. Other ingredients in the pill, such as green tea extract, can also help increase fat oxidation to burn more body fat for energy, which you experience mostly during exercise.

Last and probably the most unpopular way is by decreasing calorie absorption, which can be a combined effect of both increased thermogenesis and fat oxidation.

Phoenix seems to work as an appetite suppressant, increased thermogenesis, and increased fat oxidation.

Should You Buy Legion Phoenix?

Based on all the Legion supplements reviews we read and our own experience, we would say that there are better options. In the battle of the best fat burners, Legion is not quite up there.

We just found too much evidence of side effects like bloating and cramps. It does seem to work well to suppress your appetite but not for actual fat reduction.

Instead, we would recommend you look at PhenQ

It's one of the most scientifically backed up weight loss formula, and you'll less likely experience any adverse reactions. It does contain caffeine but in a potent enough dose without the jitters or caffeine crash.

PhenQ is also a good workout supplement as it may boost your energy to help you achieve more during your exercise.

I hope this review answered your questions about Phoenix and helped you decide whether it’s worth a try or not.

Other users have also found it effective for fat loss. The images here speak for themselves:

  1. I used this for a month and faithfully counted my calories. I still see no difference as of today but hoping for the best in the next few months!

    1. Don’t lose faith and keep trying on other products if this doesn’t work, Marcelene. Good luck!
