Collagen Peptides


Collagen peptides are small proteins from animal products.

Collagen peptides are used for aging skin, osteoporosis, brittle nails, muscle strength, and many other conditions, but there is no good scientific evidence to support most of these uses.

Don't confuse collagen peptides with collagen type I (native), collagen type II (native), or gelatin.


Is a Form of:


Primary Functions:

Aging skin, osteoporosis, brittle nails

Also Known As:

Collagen Hydrolysate, Collagen Peptidesi, Collagène Dénaturé, Collagène Hydrolysé

How Does It Work?

Collagen peptides are very small pieces of collagen. Collagen is one of the materials that make up cartilage, bone, and skin. When taken by mouth, collagen peptides seems to build up in the skin and cartilage. This may help improve some skin and joint conditions.


  • Aging skin. Taking collagen peptides by mouth seems to improve skin hydration and skin elasticity in older people. Taking collagen peptides might also lessen wrinkles, but this benefit is probably only modest.
  • Osteoarthritis. Taking collagen peptides by mouth may slightly relieve pain and improve joint function in people with knee osteoarthritis. It may take about 3-5 months of daily treatment before benefit is seen.

Recommended Dosing

The following doses have been studied in scientific research:


  • For aging skin: Usually, 2.5-10 grams of collagen peptides have been taken by mouth daily for 8-12 weeks. Specific products that have shown some benefit in clinical research include Peptan-F or Peptan-P by Rousselot, Wellnex by Nitta Gelatin, and VERISOL by Gelita AG. Combination products containing collagen peptides and other ingredients that have shown some benefit include Gold Collagen Active by Minerva Research Labs and BioCell Collagen by BioCell Technology.
  • For osteoarthritis: 10 grams of collagen peptides taken daily in one or two divided doses has been used for 3-5 months. A specific combination product containing collagen peptides and other ingredients (BioCell Collagen by BioCell Technology) has been used in a dose of 1 gram twice daily for up to 10 weeks.
