Legion Recharge Ingredients (8 grams per serving)

Micronized Creatine Monohydrate (5 grams per serving)

Creatine is a compound made up of the amino acids L-arginine, glycine, and methionine. Our body can produce creatine naturally, but it can also absorb and store creatine found in various foods like meat, eggs, and fish.

Creatine monohydrate is creatine with one molecule of water attached to it. This form of creatine has been around (and studied) for decades and is a tried-and-true winner, whereas other forms have failed to produce better results.

The creatine monohydrate in Recharge has also been micronized, which is a process that produces very fine particles that are more water soluble and easier to digest. Thus, micronized creatine monohydrate mixes better with liquid than the non-micronized form and is less likely to upset sensitive stomachs.

Research shows that supplementation with creatine monohydrate . . .

  • Boosts muscle and strength gain[8][9][10][11]
  • Improves anaerobic endurance[12][13][14][15][16][17]
  • Reduces muscle damage and soreness from exercise[18][19]
  • Increases the amount of glycogen your muscles can store[20]
  • Helps preserve lean mass and strength while restricting calories[21]

And in case you’re worried that creatine is bad for your kidneys, these claims have been horribly overblown.[22][23] Creatine supplementation isn’t advised in cases of kidney disease treated by diuretics, but in healthy people, both short- and long-term usage of creatine has no harmful side effects.[24][25][26]

The clinically effective dose of creatine monohydrate is 3 to 5 grams.[27]

Micronized Creatine Monohydrate

myHMB® β-Hydroxy β-Methylbutyrate (2.5 grams per serving)

β-Hydroxy β-Methylbutyrate (HMB) is a compound produced when the body breaks down leucine, an amino acid that stimulates protein synthesis.[28]

myHMB® is a patented form of HMB and one of the most clinically proven forms on the market, with over 150 peer-reviewed studies supporting its safety and efficacy.

HMB reduces protein breakdown, strengthens muscle cell membranes, and activates muscle-building molecules like mTOR and IGF-1.[29][30]

Research shows that supplementation with myHMB® . . .

The clinically effective dose of HMB is between 2,000 and 3,000 milligrams.

myHMB® β-Hydroxy β-Methylbutyrate

VitaCherry® Sport Tart Cherry Powder (500 milligrams per serving)

Tart cherry powder is a powdered fruit extract made from sour cherries, which are naturally rich in anthocyanins—the pigments that give the fruit its deep red color.

VitaCherry® Sport is a standardized extract made from whole U.S.-grown Montmorency tart cherries. Compared to typical tart cherry powders made from skins, it’s about 15 times more concentrated in anthocyanins.

These anthocyanins help limit the production of compounds like prostaglandins that contribute to muscle soreness after exercise, supporting faster recovery from hard training.

Research shows that supplementation with tart cherry extract . . .

  • Helps reduce exercise-induced muscle damage[43][44][45]
  • Helps reduce post-exercise muscle soreness[46][47]
  • Supports recovery of strength and power after exercise[48][49]

While researchers are still working to establish a clinically effective dose of tart cherry extract, most studies showing a benefit use between 400 mg and 500 mg per day.

VitaCherry® Sport Tart Cherry Powder

Naturally Sweetened and Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[50][51][52][53][54][55]

That’s why we use natural sweeteners like stevia, erythritol, and monk fruit instead. Research shows that these ingredients are not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol and inflammation levels, and more.[56][57][58][59]

No Artificial Food Dyes or Other Chemical Junk

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[60][61][62][63][64]

That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.
