How Collagen Peptides supports skin
For skin support, Collagen Peptides is a key 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. In clinical studies, collagen peptides supports skin elasticity, hydration, and reduces wrinkle depth.
How much collagen peptides do you need
Research points to 5–20 g as the effective range for collagen peptides. 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. Lower doses may provide some benefit, but most studies showing clear results used this range.
Which form absorbs best
Avoid hydrolyzed collagen — hydrolyzed peptides, but source not specified. Avoid gelatin — unhydrolyzed — larger molecules, lower absorption. The most bioavailable options are bovine or marine collagen peptides.
