Legion Collagen+ Ingredients (15.06 grams per serving)

SOLUGEL® Grass-Fed Collagen Peptides (15 grams per serving)

Collagen is the most abundant protein in the human body and a key structural component of your skin, joints, and connective tissues.

Collagen peptides are smaller collagen fragments that dissolve and digest more easily while still providing the amino acids your body needs to build and maintain collagen-rich tissues.

SOLUGEL® is the only certified grass-fed collagen peptide powder in the world, with sourcing and production validated by LIAF Control, a member of the American Grassfed Association.

This means our collagen is sourced from cattle that are outdoors year-round and have continuous access to fresh grass, air, land, and water—just as nature intended.

Certification matters because there’s no legal definition for “grass-fed” collagen in the United States, so companies can make grass-fed claims without proving how the cattle were raised or fed.

In other words, without third-party certification, you’re taking a brand’s word for it—and in an industry infamous for “creative” marketing claims, that’s a bad bet.

Additionally, the cattle are never given synthetic hormones, anabolic steroids, or industrial feeds, and each lot is traceable to farms in Latin America with official origin certificates.

SOLUGEL® is highly bioavailable as well, thanks to a special manufacturing process that creates smaller peptides, and dissolves more easily in liquid than standard collagen powders.

Research shows that supplementation with collagen peptides . . .

  • Supports joint, tendon, ligament, and connective tissue health[7][8]
  • Improves recovery after exercise[9][10]
  • Supports strength gains when combined with resistance training[11][12]
  • May improve skin hydration, elasticity, and wrinkles[13][14]

The clinically effective dose of collagen peptides is 15 grams.

Vitamin C (60 milligrams per serving)

Vitamin C is a water-soluble vitamin that plays many important roles in the body, including supporting immune function, skin health, and tissue repair.[15]

In Collagen+, vitamin C has a more specific job: it helps your body produce collagen and stabilize the collagen fibers that give connective tissue its strength.[16][17][18]

That makes it a logical partner for collagen peptides, which provide the amino acids your body needs to build and maintain collagen-rich tissues.

The clinically effective dose of vitamin C for supporting collagen synthesis is 60 milligrams.

Naturally Sweetened and Flavored

While artificial sweeteners, food dyes, and fillers may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[19][20][21][22][23][24]

That’s why we use natural sweeteners like stevia, allulose, and monk fruit instead as well as natural coloring and flavoring derived from fruits and other foods. Research shows that these ingredients are not only safe but can also confer several health benefits, such as supporting weight management, antioxidant activity, digestive health, and more.[25][26][27][28]

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.[29][30][31][32][33]

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.

Third-Party Lab Tested for Purity and Accuracy

Collagen+ is third-party lab tested for purity and accuracy and certified to meet or exceed FDA safety guidelines.[34]

Made in the USA with Globally Sourced Ingredients

If you want to ensure the supplements you’re swallowing every day are safe and effective, you want to buy from a company that:

  1. Sources ingredients from premium suppliers around the world (great supplements require great raw materials)
  2. Tests all products for purity and accuracy in accredited laboratories (to conclusively verify safety and efficacy)
  3. Manufactures in America, which has some of the strictest regulations in the world

And that’s exactly what we do here at Legion.
