Is there vegan collagen?
There’s no such a thing as vegan collagen. All collagen peptide powders are made from animal connective tissues such as skins, cartilages and fish scales. While you can replace your whey protein powder with vegan alternatives, you can’t replace collagen with vegetable proteins, as they don’t have enough glycine and proline, the collagen’s signature amino acids.
‘Vegan collagen’ supplements on the market contain co-factors of collagen synthesis, not the actual collagen. As we age, the less collagen we make and the more we break down, so taking collagen synthesis co-factors will not be as effective as taking collagen peptides according to the current research.
