What the brand says

Cystine Collagen WHITE is a collagen supplement containing also vitamin C, L-cystine and zinc which help produce collagen. Easy to take and easy to carry. Strawberry flavor. For collagen, its compositional balance is very important. It is common to have adequate amounts of vitamin C when taking collagen, but that is not enough to support the formation of collagen. Adding L-cystine and zinc, Cystine Collagen WHITE has achieved the best balance for collagen.
