Collagen peptides are small pieces of protein from animal collagen, which is one of the materials that makes up cartilage, bone, and skin. They are made by breaking down whole collagen proteins into smaller pieces, which can be easily absorbed by the body. Collagen peptides are used for various purposes, including aging skin, osteoarthritis, osteoporosis, brittle nails, and muscle strength. However, there is no good scientific evidence to support most of these uses. When taken by mouth, collagen peptides seem to build up in the skin and cartilage, which might help improve some skin and joint conditions. Collagen supplementation may help address the body’s natural decline in collagen production as we age. Some potential benefits of collagen peptides include:

• Better skin health and appearance: Collagen plays a vital role in skin hydration and elasticity. Taking a collagen peptide supplement may slow skin aging, including promoting the production of other vital proteins like fibrillin and elastin.

• Reduced joint pain: Collagen is crucial to maintaining cartilage, which is a strong, flexible tissue that provides cushioning in joints. Collagen peptide supplementation may slow this process.

Collagen peptides come in both pill and powdered forms and are typically made from bovine (beef) or porcine (pork) sources. Marine collagen supplements, made from fish skin or scales, are also available. However, there is no real risk associated with taking collagen peptides, and more research is needed on the overall benefits of collagen.
