High Purity Ousei Peptide Qi Supplementing and Yin Nourishing Immune Function Support Material
Polygonatum Peptide / High-purity peptide ingredient derived from Ousei (supports energy, nourishes yin, supports kidney function, enhances immune function, antioxidant, antibacterial effects)
Highly absorbent low molecular weight peptides derived from Ousei. Ideal high-content ingredient for energy replenishment, nourishing yin, strengthening kidneys and lower back, supporting immune function, and for beauty, health foods, and functional beverages.
High-purity Ousei Peptide (Polygonatum Peptide) is a low-molecular peptide material obtained by enzymatically decomposing the main protein of Ousei (Polygonatum sibiricum), which is used in traditional Chinese medicine. This product maximizes the properties of Ousei, which has effects of tonifying Qi and nourishing Yin, strengthening the spleen, moisturizing the lungs, and benefiting the kidneys, and has been developed as a nutritional functional material with excellent absorption and bioavailability. Traditionally, Ousei has been used as a plant-based material for improving conditions such as Yin deficiency, lung dryness, dry cough, little phlegm, chronic cough due to kidney Yin deficiency, soreness of the lower back and knees, dizziness, and premature graying of hair. This peptide contains polysaccharides, low-molecular sugars, amino acids, and mucin-like components from Ousei, supporting a wide range of health functions including promoting DNA, RNA, and protein synthesis in the body, activating lymphocytes, enhancing immune function, regulating blood pressure, and exhibiting antibacterial effects. This product, which has been reduced to low molecular weight through enzymatic decomposition, is smoothly absorbed in the body and is suitable for incorporation into drinks, jellies, powdered beverages, and dietary supplements. It combines plant-derived, high purity, and high functionality, making it an ideal ingredient for the modern health-conscious and functional food market.
