Collagen Peptides and muscle
For muscle support, Collagen Peptides is a supporting ingredient backed by research. Collagen is the most abundant structural protein in the body, supporting skin, joints, bones, and connective tissue. Hydrolyzed collagen peptides are broken down for better absorption — low-molecular-weight peptides (2–5 kDa) are best absorbed.
Effective dosing
Most evidence supports 5–20 g of collagen peptides daily. Most clinical studies use 5–15 g/day of hydrolyzed collagen peptides. Benefits for skin typically seen at 2.5–10 g/day, joint support at 10–15 g/day. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid hydrolyzed collagen — hydrolyzed peptides, but source not specified. Avoid gelatin — unhydrolyzed — larger molecules, lower absorption. Look for bovine or marine collagen peptides for better absorption.
