Peptides are short chains of amino acids that serve as building blocks for proteins and play crucial roles in many biological functions. They are naturally found in the body and can also be ingested through food and supplements. Peptides are used for a variety of purposes, including:
-
Medications: Peptides are used to create drugs to treat a variety of diseases, such as type 2 diabetes, multiple sclerosis, and high blood pressure.
-
Dietary supplements: Peptides are sold in dietary supplements, including pills or protein shakes, and claim to help build muscle, boost weight and fat loss, and help with muscle recovery. However, there is little direct evidence to back up most of these statements, and its not clear how well the body can absorb peptides from supplements.
-
Skin care: Peptides are found in many skin care products and may help reduce inflammation, even out skin tone, and reduce the appearance of wrinkles. They can penetrate the outer layer of the skin and send signals telling the cells to produce collagen and elastin.
-
Athletic performance: Some people take peptides and peptide hormones to enhance athletic activity. However, many of these, including follistatin, a peptide that increases muscle growth, have been banned by the World Anti-Doping Agency.
-
Other health benefits: Bioactive peptides may provide pro-aging support, anti-inflammatory, or muscle-building properties. They may also help lower high blood pressure, kill microbes, prevent oxidative stress, and prevent blood clot formation.
Its important to note that the FDA doesnt regulate cosmetics and supplements as strictly as drugs, so caution should be used when buying and using peptide products.
