Each eight tablets of this product contain 900mg of fish collagen peptide (the tripeptide content is above 15%). Nano Collagen & Hyaluronic acid Orihiro is a nutritional supplement, which contains low-molecular-weight collagen peptide. This is rich in low-molecular-weight tripeptides and dipeptides, which consist of three and two amino acids joined by peptide bonds. This product also contains low-molecular-weight hyaluronic acid and chondroitin extracted from shark cartilage. Compared to the commonly known collagen peptide, where the amino acid molecules are bonded in groups of 20–50, this product contains significant amounts of tripeptides and dipeptides, which have a low molecular size and are therefore easily absorbed.
