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?

Legion StimFree Fat Burner product sample

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 Benefits

According to their website, Phoenix contains all-natural ingredients that can help you lose an additional 1 to 2 lbs fat per month.

With a non-caffeinated weight loss formula, it appears to focus on promoting thermogenesis and enhancing appetite suppression to:

  • Speed up metabolism
  • Enhance fat burning
  • Reduce hunger and cravings

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 - KaempMax® Thai Ginseng

Also known as Thai ginseng, Kaempferia parviflora is a native herb from Thailand that has been traditionally used as an aphrodisiac. It is a good source of flavonoids found in different fruits and vegetables called methoxyflavones.

Recent studies show that it can speed up metabolism to increase calorie burning [1], boost sexual desire [2], enhance athletic performance [3], and support heart health.

Legion Phoenix contains 100 mg of Thai ginseng per serving, which is more than enough to cause effects since its clinically effective dose is around 90 and 180 mg 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 trimming 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 [4].

3 - Grains of Paradise

Commonly used as a spice, Grains of Paradise is an herb in the ginger family that contains antioxidants and functional ingredients like 6-gingerol and 6-paradol.

It is known to increase metabolic rate and energy expenditure (to about 100 calories), and stimulate fat burning within the body [5].

I commonly see this ingredient in fat burners, and our dietitian mentioned that it also works as a stimulant like caffeine.

So with that added effect, it can help burn more calories and give the boost you need for your workouts.

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 - Fucoxanthin

Fucoxanthin is a vitamin A-like molecule called carotenoid that’s naturally found in some types of seaweed. It has been shown to accelerate weight loss by producing an effect that increases the amount of energy burned by the mitochondria [6].

While there hasn’t been an established effective dose for fucoxanthin, studies have shown significant weight loss results with 2.4 to 8 mg per day. The creators of Legion Phoenix maxed up on this ingredient with 8 mg per serving.

5-HTP

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 - Caralluma fimbriata

This is an edible cactus that has been used in India for many decades to suppress appetite when there is a shortage of food.

It’s rare to see this ingredient in dietary supplements, but there have been ongoing scientific studies that it may indeed help reduce appetite [7], and regulate stress levels [8], which can make a difference in your desire to snack and overeat.

Most of my clients who tried the product for the first time had decent results in terms of curbing their appetite. But it was not as good as they hoped because there were still days when unwanted food cravings kick in.

7 - L-DOPA

As weird as it may sound, L-DOPA is a compound that stimulates the production of three popular neurotransmitters namely dopamine, noradrenaline, and adrenaline. These chemicals help you regulate focus, concentration, as well as your metabolic rate, which can instantly make you perform better during workouts.

There have been studies that associate impaired L-DOPA production with overweight and obese people, which may increase anxiety symptoms that make it harder to focus on exercising and dieting [9].

Legion Phoenix contains 150 mg of this ingredient per serving, which is enough to provide a cognitive boost without the side effects. Many studies have shown that a daily dose of 50 to 300 mg is effective in improving cognitive function.

8 - Iodine

This mineral is directly involved in the production of thyroid hormones which is known to control different metabolic functions. Although it’s uncommon to be deficient in iodine, people who restrict their caloric intake or avoid junk foods can have too little of this mineral to disrupt their metabolism.

Our dietician mentioned that it’s a good idea to boost your iodine intake of up to 500 mcg per day during calorie-restricted diets or cutting phases to have better results.

9 - B Vitamins

B vitamins are known to support your metabolism as their main function is to process the carbohydrates, fats, and protein from our diet to fuel the body. Most of these B vitamins are not stored by the body, so you naturally have to source them from your diet every day.

Legion Phoenix contains vitamin B12 which most vegans and vegetarians are deficient in. The manufacturers also added in vitamin B6 because during dieting or cutting phase, it’s quite common to be deficient in both vitamin B6 and B12, and this may hinder your efforts to lose weight.

*Update: The old formulation of Phoenix contains a mild stimulant called synephrine, and epigallocatechin gallate (EGCG), which can cause stomach problems in some people. Other ingredients removed were green tea extract, naringin, L-tyrosine, salicin, hesperidin, and hordenine.

Capsules vs. Powder

pills banner

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 to 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 the powdered products fall a bit short when it comes to taste.

Pros and Cons

Legion StimFree Fat Burner product sample

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 (more on this later).

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

Pros
  • As a caffeine-free option, it should be more suitable for taking later in the day.
  • Comes with a money-back guarantee
Cons
  • You’ll have to remember to swallow three 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 is 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.

There were also some reports on extreme headaches even when taken with food and just a third of the dose.

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 35 pills. You should take them all at once, first thing in the morning with food for optimal results.

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

Fat Burner Alternatives

PhenQ

phenq

PhenQ is one of the most effective fat burners on the market, which contains all-natural ingredients that are scientifically proven to boost your metabolism and suppress your appetite.

It has a patented weight loss formula as well as thermogenic ingredients like caffeine, turmeric, and L-carnitine to cause a significant weight reduction and lean muscle mass growth.

Compared to Phoenix which is stim-free, PhenQ does contain a small dose of caffeine, making it perfect for anyone looking to lose excess fat and suppress appetite with an extra boost.

LeanBean

Leanbean

LeanBean is an all-natural fat burner that has been specifically formulated for women.

Unlike Phoenix which uses unique ingredients like Thai ginseng and Caralluma fimbriata, this female fat burner has the common fat burning and appetite suppressing ingredients you see on supplements like green coffee bean extract, turmeric, and glucomannan.

LeanBean and Phoenix don’t seem to have common ingredients aside from some B vitamins. But they’re similar for two reasons: they don’t heavily rely on stimulants like caffeine and they tend to effectively suppress the appetite for many users.

However, LeanBean is designed for women’s specific needs and is also 100% vegan-friendly, which can explain the price difference.

Instant Knockout

Instant Knockout Box

Instant Knockout is one of the first vegan fat burners originally designed for bodybuilders and performance athletes.

It contains caffeine and glucomannan to boost the metabolism and suppress the appetite, other known thermogenics like L-theanine and black pepper extract, and several vitamins and minerals which you won’t see in Phoenix.

The main difference of Instant Knockout with Phoenix and other fat burners is the relatively high doses of its ingredients, which are proven to burn fat real quick.

It makes Instant Knockout suitable not only for professionals, but also for regular people who enjoy their gym time to lose excess weight and achieve visibly toned muscles.

FAQs

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!
