Product Overview 

Polygonatum sibiricum, commonly known as Huangjing in traditional Eastern wellness systems, has been treasured for centuries as both a medicinal and nutritional plant. It is native to the forest understories and shaded mountain slopes of northeastern Asia, including China (Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, Inner Mongolia, Ningxia, Gansu, Henan, Shandong, Anhui, Zhejiang), as well as Korea, Mongolia, and eastern Siberia.

Through advanced enzymatic hydrolysis technology, we have transformed the native proteins of Polygonatum sibiricum into low-molecular-weight bioactive peptides (<1000 Da), delivering the traditional tonic benefits of Huangjing in a modern, highly bioavailable peptide format. Unlike intact proteins or simple amino acid mixtures, these oligopeptides are rapidly absorbed through the intestinal epithelium, offering superior delivery efficiency and targeted biological activity.

Our Polygonatum Peptides are manufactured under strict food-grade conditions with ≥99% purity (UV method) , featuring a fine powder consistency (80–100 mesh) and good water solubility. The product retains the natural bioactive profile of Huangjing, making it an ideal ingredient for dietary supplements, functional foods, beverages, and sports nutrition formulations.

Key Specifications
