Overview
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.
Uses & Effectiveness ?
Possibly Effective for
- 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.
