Research indicates that bioactive peptides may:
Lower high blood pressure
Prevent the formation of blood clots
Improve immune function
Act as antioxidants
People often use peptides to try to achieve the following effects:
Slow down the aging process
Collagen is a protein in the skin, hair, and nails. Collagen peptides are broken down collagen proteins that the body can absorb more easily. Taking collagen peptides may improve skin health and slow the aging process.
Some studies indicate that dietary food supplements that contain collagen peptides can treat skin wrinkles. Other research indicates that these supplements may also improve skin elasticity and hydration.
Peptides may stimulate the production of melanin, a skin pigment, which may improve the skin’s protection against sun damage.
Topical anti-aging cosmetics can also contain peptides, which manufacturers claim can reduce wrinkles, help skin firming, and increase blood flow.
Improve wound healing
As collagen is a vital component of healthy skin, collagen peptides may facilitate faster wound healing.
Bioactive peptides can also reduce inflammation and act as antioxidants, which can improve the body’s ability to heal.
Research is currently ongoing into antimicrobial peptides, which may also improve wound healing. Having very high or very low levels of some antimicrobial peptides may contribute to skin disorders, such as psoriasis, rosacea, and eczema.
Prevent age-related bone loss
Animal research links a moderate intake of collagen peptides with an increase in bone mass in growing rats who also did running exercise.
The study may point to collagen peptides being a useful way to counteract age-related bone loss. However, more research is necessary, especially on humans.
Build strength and muscle mass
Some research on older adults indicates that collagen peptide supplements can increase muscle mass and strength. In the study, participants combined supplement use with resistance training.
Creatine peptides may also improve strength and help to build muscle.
While fitness enthusiasts have been using creatine protein powders for many years, creatine peptides are increasing in popularity.
These particular peptides may be easier for the body to digest, which means they may cause fewer digestive problems than creatine proteins.
