PEPDOO® Seaweed Peptide
Bioactive marine peptide manufactured through fermentation + enzymatic hydrolysis. Ideal for beauty, immunity, and functional food applications.
What Is Seaweed Peptide?
PEPDOO® Seaweed Peptide is a highly bioavailable marine protein hydrolysate derived from Porphyra haitanensis, a red algae species rich in essential amino acids. Through our patented process combining lactic acid fermentation and papain enzymatic hydrolysis, we produce a water-soluble, taste-optimized antioxidant peptide.
As a trusted peptide manufacturer and raw ingredient supplier, PEPDOO® delivers scalable bulk solutions for functional nutrition brands, OEM formulators, and R&D-driven enterprises.
