what does collagen peptides do

Collagen peptides are small pieces of protein from animal collagen that are made by breaking down whole collagen proteins into smaller pieces. Collagen is a key component in bones, skin, muscles, and other body parts, and taking collagen peptides as a supplement may provide several health benefits. When taken by mouth, collagen peptides seem to build up in the skin and cartilage, which might help improve some skin and joint conditions. Some of the benefits of taking collagen peptides include improved skin health and appearance, reduced joint pain, better gut health, healthier hair and nails, increased metabolism, and weight loss. Collagen peptides 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. However, collagen peptides have been shown to be generally safe and well-tolerated, and there is no real risk in taking them in proper doses.
