Collagen peptides
Collagen peptides

Background

Collagen peptides are very small pieces of protein from animal collagen. Collagen is one of the materials that makes up cartilage, bone, and skin.

Collagen peptides are made by breaking down whole collagen proteins into smaller pieces. When taken by mouth, collagen peptides seem to build up in the skin and cartilage. This might help improve some skin and joint conditions.

Collagen peptides are used for aging skin and osteoarthritis. They are also used for osteoporosis, brittle nails, muscle strength, and many other purposes, 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.
When taken by mouth: Collagen peptides are possibly safe. Collagen peptides have been safely used in doses up to 10 grams daily for up to 5 months. Side effects are rare.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if collagen peptides are safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Effectiveness

Natural Medicines rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Likely effective Effectiveness definitions
Possibly effective Effectiveness definitions
  • Aging skin. Taking collagen peptides by mouth seems to improve skin hydration and skin elasticity in older people. It might also help reduce wrinkles, but it's not clear if it helps enough to be noticeable.
  • Osteoarthritis. Taking collagen peptides by mouth might slightly relieve pain and improve joint function in people with knee osteoarthritis. But it might take about 3-5 months of daily treatment before it helps.
There is interest in using collagen peptides for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.
