What it does: It supplies amino acids such as glycine, proline, and hydroxyproline, which the body uses to build and maintain collagen networks for healthy skin, flexible joints, and strong connective tissues.
How it is used: Grass-fed collagen is commonly used in supplements for joint support, skin health, hair and nail strength, and athletic recovery, often found as a hydrolyzed powder or in capsules.
Natural sources and supplement forms: Naturally present in connective tissues and bones of animals, collagen can also be consumed from bone broth or gelatin-rich foods. Supplement forms are usually hydrolyzed (broken down for better absorption) for easier digestion.
Why it appears in supplement formulas: Brands use grass-fed collagen to help replenish the body’s collagen stores, which decline with aging, aiming to support skin firmness, joint comfort, and overall tissue strength.
What to know before use: Individuals with allergies to beef or animal-derived ingredients should avoid grass-fed collagen. Some may experience mild digestive effects, especially when starting supplementation.
Grass-Fed Collagen: A Source of Natural Type I and III Collagen
Grass-fed collagen comes from the hides of pasture-raised cows and is a rich source of Type I and III collagen, the main types found in skin, tendons, and bones. Because collagen is a protein built from amino acids like glycine and proline, this supplement provides the same basic building blocks found in bone broth and other traditional dishes made with boiled animal bones and connective tissues.
