Why Collagen Peptides for Hair
Collagen Peptides is a supporting nutrient for hair support. 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. Branded bioactive peptides are optimized for specific outcomes: Verisol (2.5 g/day, clinically studied for skin elasticity and wrinkle reduction), Fortigel (5–10 g/day, targeted at cartilage and joint health), and Peptan (general-purpose, broad clinical data across skin, joints, and bones). In clinical studies, collagen peptides supports nail strength and hair health.
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.
