The Benefits and Applications of Peptide Supplements
Introduction to Peptide Supplements
Peptide supplements have garnered significant attention in recent years due to their potential health benefits. These short chains of amino acids, derived from various protein sources, are known for their bioactive properties, which can influence numerous physiological processes. This article explores the diverse applications and benefits of peptide supplements, drawing insights from recent research.
Collagen Peptides for Skin Health
Enhanced Skin Elasticity and Collagen Synthesis
Collagen peptides, particularly those enriched with X-Hyp or X-Hyp-Gly, have shown promising results in improving skin health. A clinical study demonstrated that oral supplementation with these peptides significantly increased skin elasticity and collagen synthesis in the dermis. Participants who consumed collagen peptides exhibited a notable improvement in skin elasticity and a substantial increase in collagen synthesis compared to those who consumed normal collagen hydrolysates. This suggests that collagen peptides could be a valuable addition to skincare regimens.
Milk Protein-Derived Peptides
Multifunctional Bioactivities
Milk protein-derived peptides are recognized for their multifunctional bioactivities. These peptides can modulate various regulatory processes in the body, including opioid receptor activity, antihypertensive effects, immunomodulation, antimicrobial properties, and antithrombotic activities . Their ability to reach target sites in the body, either at the luminal side of the intestinal tract or in peripheral organs after absorption, makes them versatile components in both dietary supplements and pharmaceutical preparations.
Cardiovascular Health
Milk-derived bioactive peptides have also been linked to cardiovascular health benefits. They can promote lipid-lowering, antihypertensive, immunomodulating, anti-inflammatory, and antithrombotic effects, which are crucial in preventing atherosclerosis and other cardiovascular diseases . These peptides are increasingly being incorporated into functional foods and dietary supplements to leverage their health-promoting properties.
Plant Protein-Derived Peptides
Antioxidant Properties
Plant protein-derived peptides have gained attention for their antioxidant capacities. These peptides can help in treating oxidation-related diseases and delaying food oxidation, thereby improving the quality of life. Recent advances in the preparation, purification, and identification of these peptides have facilitated their commercial production and application in functional foods and nutritional supplements .
Peptides for Metabolic Health
Glucose Homeostasis and Insulin Sensitivity
Peptides derived from soy-fermented douchi, such as VY (Val-Tyr) and SFLLR (Ser-Phe-Leu-Leu-Arg), have shown potential in improving glucose metabolism and insulin sensitivity. Studies on high-fat diet-induced insulin-resistant mice revealed that these peptides could reduce body weight gain, insulin resistance, hyperglycemia, inflammation, liver injury, and lipid accumulation. They also positively influenced gut microbiota, enhancing the abundance of beneficial bacteria. These findings suggest that such peptides could be used as a dietary strategy for preventing type 2 diabetes.
Peptides in Poultry Nutrition
Egg Quality Enhancement
Peptide supplementation in poultry diets has been investigated for its effects on egg production and quality. Research indicates that incorporating peptides from enzymatic hydrolysis of soybean protein into laying hens' diets can maintain body weight and improve internal egg quality during storage. Although there were no significant effects on egg production, peptide supplementation enhanced yolk color and albumen height, contributing to better egg quality.
Conclusion
Peptide supplements offer a wide range of health benefits, from improving skin elasticity and cardiovascular health to enhancing metabolic functions and egg quality in poultry. The diverse bioactivities of peptides derived from collagen, milk, and plant proteins make them valuable components in functional foods, dietary supplements, and pharmaceuticals. As research continues to uncover their potential, peptide supplements are poised to play a significant role in promoting health and well-being.
