Published Jan 10, 2017.

There are positives and negatives to Legion Phoenix. On the one hand, there is a good money-back guarantee, and there are some rave reviews from people who have tried it. But on the other hand, there is the potential for some serious side effects, particularly from the bitter orange extract. The company actually look pretty reputable, but we would still recommend extreme caution with this product.


  • Full ingredient quantities released
  • Excellent money-back guarantee
  • Overwhelmingly positive reviews


  • Contains bitter orange extracts
  • Claims there are no side effects; the ingredients list disagrees
  • Possible serious side effects
Legion Phoenix
Whilst Phoenix, by Legion Supplements, does not name any other products expressly by their title, they claim that other companies are using technical and complex marketing terms to dazzle customers into buying their products without any research, whereas they don’t.

We take a look to see if Legion Phoenix is really better than other diet pills available.

Legion Phoenix Overview

What you need to know about Legion Phoenix

This is a difficult one. On the one hand, the product has excellent reviews from customers, and a great money-back guarantee. However, customers are being told that this product contains no stimulants and causes no side effects, which are both incorrect.

The individual ingredients can cause serious side effects, although the incidence of these varies from person to person. There is also an extensive list of people who should avoid the product for health reasons, making it unsuitable for a large group of the target market, i.e. people who are trying to lose weight.

Whilst the ingredients list is generally promising, with significant amounts of clinically proven weight loss ingredients such as Naringin, Green Tea Extract, and 5-HTP, there are some of the ingredients that we are more concerned about. Synephrine and Hordenine are stimulant ingredients, which are associated with numerous side effects, although this has been overlooked because they are linked strongly with significant boosts to weight loss. Some of the other ingredients such as Hesperidin and Forskohlin have zero or limited potential for weight loss, with the supporting clinical studies being mediocre at best.

What are the side effects of Legion Phoenix?

There are numerous, and potentially dangerous, side effects associated with the ingredients of Legion Phoenix. For a full list, please see the Side Effects tab below.

How much does Legion Phoenix cost?

One bottle costs $34.95 plus delivery, and contains 120 capsules, enough for 30 servings. There is also a discounted offer for those buying the triple pack, which costs $93.95 instead of $104.95.

Legion Phoenix Key Features

Legion supplements are the manufacturers behind the relatively new product, Phoenix, which is a fat burner. Legion Supplements was created by Mike Matthews, a health and fitness author who has released numerous successful titles and has a huge and devoted fan base. The about page of the website details how Mike Matthews hates ‘the exaggeration, lies, overblown advertising, and confusing pseudoscience of the industry’ as much as his customers. Whilst this is refreshing, as there are certainly a lot of fraudulent claims and scams being run within the diet pill industry, we do have some issues with this claim.

Mike has told customers via his official Facebook page that Legion Phoenix contains no stimulants, when in reality hordenine and synephrine are stimulant ingredients that are known to stimulate the metabolism. Whilst this is a minor point, we feel that this could be misleading to customers who put a great deal of faith in Mr Matthews.

Legion Phoenix Key Points

  • Manufactured by Legion Supplements
  • 120 capsules per bottle – 30 servings
  • Fat Burner containing stimulant ingredients

Mr Matthews has also claimed on numerous sites (Amazon, Facebook, and his own website), that the product has no side effects. Looking at the individual ingredients used, there are a whole host of possible side effects which could occur, as detailed below. In line with the idea that this product supposedly has no side effects, only the positive aspects of each ingredients are discussed on the product website.

The contact page has a full set of contact details, including a contact box, email addresses and a phone number, complete with opening times. Mike (or perhaps one of his employees) is also active on his Facebook page, replying to customer comments regularly. The company is based in Clearwater, Florida, and a full address is provided on the official website.

How to Take Legion Phoenix

Two capsules are to be taken, twice daily, with meals.

Some of these ingredients look incredibly specialist and technical, until their source is considered; for example Epigallocatechin gallate is extracted from Green Tea, which is an incredibly common ingredient in diet pills. Similarly, Hordenine and Synephrine are both from Bitter Orange, another incredibly common ingredient used in diet pills.

Legion Phoenix Concerns:

  • Contains bitter orange extracts
  • Claims there are no side effects – when ingredients list disagrees
  • Possible serious side effects

There is clinical evidence to support the majority of these ingredients being a valid weight loss aid, but there are a few ingredients that have inconclusive evidence about weight loss. For example, Forskohlin may decrease fat mass, but it did not contribute to any weight loss in the relevant studies.

In general, the ingredients here are present in significant doses, similar to the doses used in clinical trials.

What does Legion Phoenix claim to do?

After a long introduction describing how many other fat burners are inferior products using small quantities of cheap stimulants and other under-dosed, unproven or ineffective ingredients, the official Phoenix webpage eventually gets around to describing how their own product supposedly does work. They state:

PHOENIX’s formulation is the result of an extensive scientific review of a wide variety of natural molecules known to favorably affect fat loss, and we carefully chose a handful that work synergistically to safely deliver consistent results on all three points described above. The result is the most powerful combination of safe, natural fat-burning agents on the market. Every ingredient is backed by sound clinical research and is included at clinically effective dosages.

The ‘three points described above’, are the three ways of increasing the rate of weight loss, i.e. increasing your basal metabolic rate, reducing hunger, and making the ‘overall experience of dieting more enjoyable’.

The website then describes how the product works in detail, by going through each individual ingredient and its properties.

Does Legion Phoenix work?

Although the formula is not perfect, containing some ingredients that have less clinical support than we deem necessary (e.g. Forskohlin), in general this diet pill does seem to boost weight loss consistently. The customer reviews certainly support this, being overwhelmingly positive.

The reviews also demonstrate that this fat burner works best when used in conjunction with an active lifestyle, regular exercise and a calorie balanced diet.

Legion Phoenix Ingredients

The ingredients list provided on the official website is detailed, providing not only the ingredients, but also including the quantity of each ingredient used. The quantities provided below are per serving of 4 capsules, which is the total and maximum dose per day. Two capsules are to be taken, twice daily, with meals.

The websites recommends that for maximum results, customers should combine the product with caffeine. Caffeine not only boosts the metabolism, but also interacts with several of the ingredients found in this diet pill, primarily synephrine, to increase the potency of the diet pill further. Customers may want to reintroduce caffeine into their diet slowly to minimize the chances of side effects from occurring.

  • Synephrine (50 mg): A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it.
  • Naringin (600 mg): A compound found in grapefruits that accounts for its bitter taste, it is known to extend the amount of time that caffeine remains in the body. This would make the effects of caffeine also last longer. Research also suggests that Naringin enhances lipid (fat) metabolism in the body, which again could have positive implications for dieters.
  • Hesperidin (100 mg): Usually found in citrus fruits, this bioflavinoid is typically used to treat problems with circulation and blood vessels. Whilst many sources claim there is little to link this ingredient with weight loss, the official product website suggests that hesperidin works synergistically with synephrine and Naringin to increase the body’s metabolic rate significantly.
  • Epigallocatechin gallate (from green tea extract) (400 mg): Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins, especially one called Epigallocatechin gallate (EGCG) increase energy expenditure by boosting the metabolism temporarily. However, the metabolic increase caused by green tea is limited. One study found that the use of green tea was not enough to counteract weight gain following a very low calorie diet. The extract of green tea used in this diet pill contains no caffeine, and consists only of the EGCG antioxidant.
  • Salicin (White Willow Bark Extract) (120 mg): Willow bark contains salicin, which acts a painkiller, and is thought to be as effective as aspirin. There is some evidence that when taken in conjunction with kola nut and ephedra, it can cause weight loss. It does not seem to have been tested on its own for weight loss properties.
  • L-Tyrosine (150 mg): An amino acid that is a building block of protein, this ingredient is found naturally in many foods including meat and dairy products. Some people use it as an appetite suppressant, but there is little evidence that it is effective for this use. Large doses of tyrosine may be useful for increasing alertness, especially in people who are sleep deprived.
  • Forskolin (50 mg): This is extracted from a plant belonging to the mint family that is thought to boost the metabolism, called Coleus Forskohlii. However, the clinical trials performed using this ingredient have shown no weight loss, even when the participants’ lean muscle mass increased and fat mass decreased.
  • 5-HTP 150 mg: 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood.

Legion Phoenix Side Effects

5HTP has been associated with numerous side effects; it is unknown whether these side effects were caused by a compromised product, a contaminant, or by the product itself.

Web MD states,

There is concern that it can cause a serious side effect called eosinophilia myalgia syndrome. Some people think this side effect is only caused by a contaminant in some 5-HTP products; however, there is not enough scientific evidence to know if it is caused by 5-HTP, a contaminant, or some other factor. Until more is known, 5-HTP should be used cautiously.

Other potential side effects of 5-HTP include nausea, nightmares, heartburn, stomach pain, nausea, vomiting, diarrhoea, drowsiness, sexual problems, and muscle problems.

Hesperidin supplements cause only occasional adverse effects, including nausea, vomiting, diarrhoea and allergic reactions.

Synephrine and Hordenine are both extracted from Bitter Orange, and side effects associated with these stimulants include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of Bitter Orange extracts because in their opinion, the risk of using the product is not worth the pay-off of some weight loss that could be achieved using other means.

Customers should remember that the effects of synephrine are enhanced when combined with caffeine. Those who find this diet pill to be strong without caffeine, should avoid caffeine use in general whilst using the product, as consuming caffeine does increase the chances of side effects.


Not intended for use by persons under age 18.

Do not exceed recommended dose.

Do not consume synephrine from other sources while taking PHOENIX.

Consult your physician prior to use if you are pregnant or nursing, or if you are taking medication, including but not limited to MAOIs, SSRIs, or other antidepressants or antipsychotics.

Individuals with a known medical condition should consult a healthcare professional before using any dietary supplement.

Exert caution when using PHOENIX alongside other stimulatory and neurologically acting dietary supplements.

Legion Phoenix Customer Feedback

Despite there being a testimonials and reviews section on the official website, there are no reviews or testimonials from customers posted here.

Elsewhere on the internet, we have been able to find several reviews, primarily on Amazon. The product only started being shipped on August 13th 2014, but there are a surprisingly large number of reviews that have been left in only 2 months. Many of the customers seem to have purchased other Legion products or books written by Mike Matthews, the founder of the company. All of the reviews are positive, and many of the reviewers are following strict diet and exercise regimes, many of which are designed by Mike Matthews.

2.1 lbs down from the first week of use — and i didn’t even do cardio this week (next week I will).

I’ve been following Mike’s workouts & reading his books for the last year or so Tried most of the Legion products as well. So far I’m impressed with the Phoenix Fat Burner. Cravings are lower. I’ve dropped a lb or two. I like the fact it has no caffeine so it doesn’t interfere with my pre-workout or a cup of coffee before my 4am gym time.

Simply amazing! Associated with a proper diet, this product really helps to keep under control the appetite. The results I am getting are amazing, and I will continue buying it. Thanks Mike once again for helping many people in reaching their goal!

Simply put, this product works great.

I wish I could post my MyFitnessPal weight loss chart over the last 3 months as it clearly shows a significant increase in weight loss since I started taking my first bottle of Phoenix on August 12th. I follow my diet and exercise plan very close and I typically lose about 0.8lbs per week.

Since taking Phoenix the 0.8lbs per week jumped up to about 1.3lbs per week. I didn’t change my diet plan so I could isolate the effects of Phoenix. I was pretty shocked at how good the product actually worked. I had taken other fat burners in the past, and never really noticed much for results (but to be fair my diet was not as accurate as it is now)

I finished my first bottle a few days ago and am extremely pleased with the results. Looking forward to my next bottle.

I would recommend this product to anyone!

Legion Phoenix Money-Back Guarantee

The money-back guarantee on this product is actually pretty good. Customers are offered a three month guarantee, minus shipping.

However, for fraud protection, we require the return of product for any refunds beyond the first bottle. This guarantee is valid for all Legion formulas, with the exception of WHEY+, which is required to be returned to qualify for a refund.

Where To Buy Legion Phoenix

Legion Phoenix can be purchased from the official Legion Athletics website. One bottle costs $34.95 plus delivery, and contains 120 capsules, enough for 30 servings. There is also a discounted offer for those buying the triple pack, which costs $93.95 instead of $104.95.

It is also available from amazon, although at the time of writing, it was out of stock, and so no price was available.

Watchdog Verdict

Legion Phoenix is hard to rate, for it has numerous good points, but a few bad points that we cannot just ignore.

Phoenix may be a good potential diet pill for some, especially if they are willing to overlook the potential of side effects from occurring. However, we would recommend consumers avoiding products that have ingredients that have caused heart attacks, coma and even death in healthy patients before.

We reject Legion Phoenix.

Have Your Say

14 comments on 'Legion Phoenix'

  1. This product definitely keeps me awake at night when I take my second dose as early as 11am, and gives me HORRIBLE gas. Bummer because I really do believe in Mike M and have many of his books. I wish this stuff worked for me but I will have to stop taking it.

  2. Does anyone know what the interaction is between the active ingredients and SSRIs that precludes the taking of both?

  3. Being a logical and research driven person, I have to say that this review of Legion is “REJECTED” for 2 reasons
    1) You did not actually use the product in a case study and prove any results whatsoever.

    2) None of your claims for bitter orange extracts or 5-HTB were backed up by any proof whatsoever.

    I do use Mikes’s products for a few reasons.

    1)Clear and concise labeling of ingredients, even though the print is WAY to small.
    2)Natural supplements
    3)After 2 months of use, I can say that this product does help with loosing stubborn fat.
    4)There are no miracle weight loss products, but at least Mike is trying to be an “honest” promoter of his products and using ingredients that have been proven to help in loosing FAT.

    If his product was not helping me after 2 months, I would have stopped using it, their customer service is excellent and so is the warranty. They have been very helpful and appear to be honest in their efforts to make a quality product and back it up on their website. As with any product like this, you should always consult your doctor (not Web MD) if you have any concerns.

  4. I have not used this supplement but from what I can see this seems to at least be more above board than the usual fare because there is actual specific information on the ingredients and doses.

    That said the issue with all supplements of this sort (aside from the scant evidence compared to pharmaceutical drugs) is the inability to be sure that the contents are as stated. It would be more useful (though also costly) to actually test different supplements and see if they contain what they purport to contain in the quantity they state.

    Only then does it actually become relevant what the scientific evidence is regarding effectiveness and I don’t believe it is possible to recommend or review any supplement unless you know exactly what it contains.

    Drugs have to contain what they state by law and are very tightly regulated, supplements on the other hand have virtually no oversight.

    BTW as far as I am aware eosinophilia myalgia syndrome was associated with contaminated batches of pharmaceutical L-Tryptophan (from a Japanese lab in the 1980s) not 5-HTP – if you have some information relating to 5-HTP and EMS please link to it or reference it. Otherwise the statement is inaccurate.

  5. Mike Matthews is not a doctor, nor a nutritionist, nor a scientist yet he comes out with his own “better and more efficient and safer” products and at the same time says that most of the products on the market are junk. Fat loss is a by-product of healthy eating and exercise, not from a pill, powder or liquid.

    His website is consumed with talking about his philosophies yet scattered throughout each page are links to purchase his products (books, suppliments and such). This is a tactic used by numerous “self-help” gurus, that are not in it to actually help people but to make money for themselves. The reason I state this, is because I have created many websites for such people in the past and their main focus was to promote their products not to have the viewer actually read what they were trying to say. I am not saying that Mike Matthews is attempting this tactic, but is highly appears to be in the same line as those others.

    1. I can tell you that Mike is not using this approach. Yes, he is selling his products on his site, but I’ve been following him since before he had his own supplement line and he has always had the same philosophies and outlook on the industry.

      The guy is a top dude. Always interacting with his audience and eager to help. it’s a breath of fresh air to have someone sincere and down to earth like Mike around.

    2. So after years in his field he shouldn’t want to bring products out that are better than what other companies have out there? That’s ridiculous.

    3. It’s pretty clear Matthew has never really researched any of Mike Matthew’s material. There is science behind all of Mike Matthews recommendations. Yes, if you take a .001 second glance at it you might think he’s pushing his supplements, but before he had his own line he put out supplement recommendations for other products that were straightforward and backed by science. Even now with his own supplement line, he still provides guidance on those other supplements. He doesn’t only push his own products.

      Do your research before posting utterly false comments, Matthew.

  6. I have went through about 3 bottles of this product so far and have found it to be very effective with diet and exercise. I’m not sure what
    product description was used for the review but I can say that whenever Mike Matthews talks about this product on his podcast he does mention that is is a mild stimulant.

    I’d be interested to know in the ingredients that are said by the reviewers to cause heart attack and coma, are those side affects based on the dosage that is in this product, or did those affects come from people abusing the ingredients? Would you consider any product containing caffeine to be too risky because it may cause heart attack?

  7. I agree with the man himself Mike Matthews himself, those were some very weak points you made. If a “fat burner” increases the rate that fat is burned with no side-effects for 99% of the population, I find it a bit disappointing that you “rejected” the product. I think it’s definitely worth another look. Personally, I have used it and enjoyed good results.

  8. I am now officially afraid to try this after reading all about it. I have high blood pressure and now im afraid to take it.

    1. Great product, I like that Mike takes the time to further explain his thoughts which are based on researched facts. But I’m not sure of many things out there that don’t warn of potential side effects. Heck my Vitamin D and Fish Oil contain possible side effects. Lets not get all wrapped up in this fact.

  9. Thanks for the review on my product! I appreciate it.

    I just wanted to address a few points if I may:

    1. If I said anywhere that Phoenix is stim-free, that was a mistake. I do say that synephrine is a mild stimulant–much milder than caffeine–and, in my experience working with thousands of people, is very well tolerated.

    Which brings me to…

    2. While there is definitely a chance of people experiencing non-optimum side effects from taking bitter orange extracts, I’ve yet to hear about it. That is, I’ve yet to have a single person contact me or Legion complaining about stimulant side effects.

    The only complaint I’ve heard from a handful of people is Phoenix made them gassy, but this was resolved by having them take it with a meal containing some soluble fiber.

    3. I’m a little confused by your critique of forskolin. Decreasing fat mass is exactly what we want. Losing WEIGHT isn’t the goal, really–losing FAT is.

    That said, I do anxiously await further research on this molecule and will adjust Phoenix accordingly depending on the findings.

    4. Remember that Web MD is often a bit over the top in their side effect warnings. If you took them at face value you’d think a cup of coffee per day is going to explode your heart, haha.

    Again if customers were complaining about non-optimum side effects associated with the bitter orange extracts, I would definitely remove them.

    Hope this helps to clarify! Thanks again for the review!

    1. Thanks for commenting Mike! Once again your honest approach to business, your knowledge of your field, and your friendly replies get me to purchase another one of your products! Will definitely be trying Phoenix in the coming week!
