Legion Phoenix | Fat Burner Supplement

Q: How do I use Phoenix?

Take 3 capsules daily. For optimal results, take first thing in the morning with a meal.

Q: How quickly will I see results with Phoenix?

You'll see results fairly quickly with Phoenix. If you know what you’re doing with your diet and exercise, and you take Phoenix every day, you can expect to lose, on average, an additional ½-to-¾ pound of fat per week. One serving of Phoenix per day can help your body burn up to an additional 300 calories and benefit from several other mechanisms that accelerate fat loss.

Q: What’s the difference between caffeinated Phoenix and stim-free Phoenix?

The only difference between caffeinated Phoenix and stim-free Phoenix is the inclusion of caffeine in the caffeinated version of Phoenix. While caffeine can boost your metabolism and performance, you don’t want to take too much in a single day, which is why we created the stim-free version of Phoenix for people who get their caffeine from other sources.

Q: How does Phoenix differ from Forge? Can they be used together?

Although both Phoenix and Forge are fat burners, they work in slightly different ways. Phoenix helps you lose fat by boosting metabolic rate, improving the body’s ability to metabolize body fat, and reducing appetite and cravings (and carb cravings in particular), and you can get these benefits regardless of whether you’re in a fasted or fed state. Forge helps you lose fat by mobilizing “stubborn” body fat, which can then be burned for energy, but it’s only beneficial when taken before fasted training. (Forge also marginally boosts metabolic rate, but not enough to warrant taking it if you aren’t also fasted training.) As to whether they can be used together—absolutely! In fact, we created Phoenix to work synergistically with our fat burner Forge and pre-workout supplement Pulse . When taken together, these three supplements are a powerful fat loss “stack” that helps you lose fat as quickly, healthily, and enjoyably as possible.

Q: Even if Phoenix helps me lose weight, will I just gain it back when I stop taking it?

No. No, you won't just gain back the fat you lose while taking Phoenix. The only way you can regain the fat Phoenix helps you lose is by dramatically overeating after you’re done dieting, which is a common mistake many people make.

Q: Is Phoenix for men and women?

Yes, Phoenix is absolutely for both men and women!

Q: What’s the difference between the old and new formulation of Phoenix?

The difference between the old and new formulation of Phoenix is the new version of Phoenix significantly increases energy expenditure, is better at reducing hunger and cravings, and better supports mood and cognition while dieting. We also removed epigallocatechin gallate (EGCG) from the formula because it can cause stomach upset in some people when taken on an empty stomach.

Q: Are there any side effects I should know about?

You shouldn’t notice any. No jitters, nausea, or discomfort of any kind. That said, if you’re taking an SSRI or similar antidepressant, you should not take Phoenix without first consulting your doctor. This is because the 5-HTP in Phoenix can interact with these drugs, potentially causing your serotonin levels to get dangerously high.

Q: What does the Prop65 warning on the labels mean?

Our products include a Proposition 65 warning in compliance with California’s regulatory guidelines, which are among the most stringent and sweeping in the world. A Proposition 65 warning does not indicate whether a product is safe or unsafe. Rather, Proposition 65 is a consumer notification law in California that requires warnings to inform consumers about the presence of one or more of over 900 substances in various types of products. These substances include naturally occurring and ubiquitous compounds, even when present at levels below those known to cause harm.

Legion Phoenix Ingredients (1,690 milligrams per serving)

Caffeine (200 milligrams per serving)

Caffeine is a naturally occurring substance found in many plants native to Africa, East Asia, and South America, including various kinds of tea, cocoa, and coffee.

Caffeine’s primary effects in the body are to stimulate the central nervous system and block the activity of another chemical—adenosine—that causes tiredness.

Research shows that supplementation with caffeine . . .

Boosts mood and energy levels[10]
Improves focus, drive, and wakefulness[11][12][13]
Increases metabolic rate[14]
Enhances strength and power[15][16][17][18][19]
Boosts endurance[20][21][22]
Improves anaerobic performance[23][24][25][26][27]

The clinically effective dose of caffeine for enhancing energy, focus, and performance is between 1 and 6 milligrams per kilogram of body weight.[28][29][30]

Black Ginger (100 milligrams per serving)

Black ginger, also known as Kaempferia parviflora, is an herb native to Thailand that has traditionally been used to improve virility and physical performance and support weight management.

It contains several active compounds known as methoxyflavones, which appear to improve body composition in several ways, including . . .

Enhancing blood flow by inhibiting an enzyme called PDE5 that causes blood vessels to contract[31]
Increasing energy expenditure by causing an effect in fat cells known as uncoupling[32]
Decreasing fat storage by influencing a receptor known as PPARy[33]

That’s why research shows that supplementation with black ginger . . .

Significantly increases calorie burning[34]
Improves sexual wellbeing in men[35]
May improve physical performance and activity[36][37]

The clinically effective dose of black ginger is between 90 and 180 milligrams per day.

Grains of Paradise (30 milligrams per serving)

Grains of Paradise is the common name for the plant Aframomum melegueta, which is a herb in the ginger family that’s commonly used as a spice.

It contains various compounds like 6-gingerol and 6-paradol that can increase the metabolic rate by influencing receptors on fat cells involved in energy regulation and perception of temperature.

That’s why research shows that supplementation with Grains of Paradise increases energy expenditure (to the tune of about 100 calories) and reduces visceral fat levels.[38][39]

The clinically effective dose of Grains of Paradise is around 30 milligrams of an extract providing 3-to-4 milligrams of 6-paradol.

Forskolin (50 milligrams per serving)

Forskolin is a substance found in the Indian herb Coleus forskohlii, which has long been used in Ayurvedic medicine to treat heart and respiratory disorders.

Supplementation with forskolin increases blood plasma and intracellular levels of a molecule known as cAMP (cyclic adenosine monophosphate), which stimulates the production of cellular energy.[40][41]

This is why research shows that supplementation with forskolin accelerates fat loss and appears to increase testosterone levels as well.[42]

The clinically effective dose of forskolin hasn’t been established yet, but 25-to-50 milligrams of forskolin per day is known to be effective.

Fucoxanthin (8 milligrams per serving)

Fucoxanthin is a vitamin A-like molecule known as a carotenoid that’s found in seaweed.

It enters fat cells and produces an effect known as uncoupling, which increases the amount of energy that mitochondria burn.[43]

This is why research shows that supplementation with fucoxanthin can accelerate weight loss.[44]

Additionally, studies show that it can also hinder fat storage by inhibiting the absorption of glucose into fat cells and augmenting its uptake into muscle cells.[45][46]

The clinically effective dose of fucoxanthin hasn’t been established yet, but 2.4-to-8 milligrams per day is known to be effective.

Caralluma Fimbriata (1,000 milligrams per serving)

Caralluma fimbriata is an edible cactus found primarily in India that has long been used to suppress appetite when food is scarce.

Scientists are still investigating how it works, but research shows that supplementation with Caralluma fimbriata does indeed reduce appetite as well as stress and cortisol levels, which can further decrease the desire to overeat.[47][48]

The clinically effective dose of Caralluma fimbriata is 1,000 mg of a 14:1 extract (equivalent to 14 grams of the raw plant) per day.

5-HTP (150 milligrams per serving)

5-HTP is a compound produced by the metabolism of the amino acid tryptophan, which is found in foods like milk, meat, potatoes, pumpkin, and various greens.

It’s converted into serotonin in the brain, which is one of the principal neurotransmitters involved in feelings of happiness.

Research shows that supplementation with 5-HTP . . .

Supports mood[49]
Increases feelings of fullness and helps control food intake[50]
Reduces cravings for carbohydrates in particular[51]

The clinically effective dose of 5-HTP is between 150 and 500 milligrams.

L-DOPA (150 milligrams per serving)

L-DOPA is a compound involved in the production of the neurotransmitters dopamine, noradrenaline, and adrenaline—chemicals that help regulate focus, attention, and metabolic rate, among other things related to physical activity and cognition.

L-DOPA production tends to be impaired in overweight and obese people, and this can cause reduced focus and brain fog.[52] Although weight loss alone can normalize L-DOPA levels, supplementing with it during periods of dieting can help preserve mood and cognition.

The clinically effective dose of L-DOPA is between 50 and 500 milligrams, with lower doses used for subtle cognitive boosts.

Iodine (240 micrograms per serving)

Iodine is a mineral that’s involved in the production of thyroid hormones, which regulate metabolic rate. Thus, too much or too little iodine in one’s diet can hinder metabolic function.

Although iodine deficiency is rare among the general population, insufficient intake can occur during dieting through calorie restriction and the avoidance of salty prepackaged (“junk”) food.

Thus, it’s prudent to bolster iodine intake during a cutting phase, but not higher than 500 micrograms per day as this may suppress thyroid activity.[53][54]

Vitamins B6 (1.7 milligrams per serving) and B12 (2.4 micrograms per serving)

B vitamins, including B6 and B12, are involved in the production of cellular energy and the metabolism of food. They’re also commonly associated with focus and attention.

Although deficiencies of these vitamins are generally rare, B12 is commonly deficient in vegans and occasionally in vegetarians, and B6 is often insufficient in all diet types.[55][56]

Furthermore, the risk of B6 and B12 insufficiency rises when dieting, so supplementation with both is prudent during a cutting phase.

There is no clinically effective dose of vitamin B6 or B12, but 1 to 2 milligrams of B6 and 2 to 3 micrograms of B12 per day is enough to maintain sufficiency.

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

Many fat burners rely primarily on a heap of cheap stimulants to work, including chemicals that can be harmful to your health when consumed regularly.

Phoenix, on the other hand, comes in two versions:

Without any stimulants whatsoever
With a safe dose of just one well-tolerated stimulant: caffeine (200 mg per serving)

What’s more, Phoenix doesn’t contain any dubious artificial ingredients or unnecessary chemical additives like food dyes or artificial sweeteners.

No Artificial Food Dyes or Other Chemical Junk

Third-Party Lab Tested for Potency & Purity

Every bottle of Phoenix is analyzed in a state-of-the-art ISO 17025 accredited lab to verify what is and isn’t in it. That way, you know exactly what you’re getting and putting into your body.
