Hydrolysed marine collagen powder in its purest form The study-tested marine collagen NATICOL® is obtained from fish skins and supplies collagen in hydrolysed form, i.e. in a further processing step the collagen peptides are broken down into smaller pieces (enzymatic cleavage). This means that it can be better absorbed and broken down by the body. The plus in Collagen Superior stands for the additional nutrient support with zinc, biotin and valuable plant extracts, which have positive effects on skin health and support the development of skin, hair and nails. Let your skin glow from within and try this delicious collagen drink!
