Collagen peptides are bioactive. That is, once absorbed into the bloodstream, they can affect the activity of cells in the body in a variety of ways. For example, collagen peptides can stimulate fibroblasts in the skin to produce more hyaluronic acid, which is essential for skin moisture.

Bioactive collagen peptides can help the body repair damaged tissue. It can provide structural support to the skin, contribute to healthy hair and maintain bone density. Because of this, collagen peptides are used for a range of beauty and fitness needs.

For example, various scientific studies have shown that collagen peptides can help improve joint health by protecting cartilage from degradation and reducing inflammation around the joint. This has beneficial effects for people with joint disorders as it can improve mobility and reduce pain.

Sports & Recreation

Collagen peptides are used by athletes, bodybuilders and sports enthusiasts to reduce their recovery time after intense exercise. Strenuous activity puts a strain on muscle fibers and the connective tissue covering, so the body needs time to heal before exercising more.

Collagen peptides can support recovery by reducing recovery time, meaning athletes can maximize their training schedule and improve performance.

In addition to reducing recovery times, taking collagen peptides can also reduce muscle soreness.

Bones & Health

Collagen peptides can support bone health. Bones consist mainly of collagen and calcium salts. Throughout a person's life, bones are constantly repairing and regenerating in a process known as bone remodeling.

As a dietary supplement, collagen peptides can be used to speed up the bone remodeling process and maintain bone health. In one study, researchers found that collagen peptide supplementation can affect the metabolism of bone cells at multiple levels, promoting the remodeling process and helping the body maintain the strength of its bones.

Beauty & Skincare

Collagen peptides are also used with the aim of slowing down visible signs of aging such as wrinkles. There are several scientific studies that demonstrate the ability of collagen peptides to support skin beauty. In 2015, the results of two clinical studies showed that collagen supplementation improved skin appearance and hydration in Caucasian and Japanese women, respectively. Another 2019 study confirmed that collagen peptide supplementation had beneficial effects on the skin in participants of different skin types.
