Collagen Peptides and Vitamin C Liposomal, a synergy.

Q: Can I take Collagen Peptides and Vitamin C Liposomal together?

Yes. The combination of Collagen Peptides and Vitamin C Liposomal produces a measurable benefit. Vitamin C Liposomal is essential for collagen synthesis. It's a required cofactor for prolyl and lysyl hydroxylase enzymes that stabilize the collagen triple helix.

Q: How does this affect a NutriStack Stack Score?

+2 to your Stack Score per scored synergy row.

Synergy

What is happening. Vitamin C Liposomal is essential for collagen synthesis. It's a required cofactor for prolyl and lysyl hydroxylase enzymes that stabilize the collagen triple helix.

Mechanism. Ascorbate is the electron donor for prolyl-4-hydroxylase and lysyl hydroxylase, which hydroxylate proline and lysine residues essential for collagen triple helix stability.

Recommendation. Always take vitamin C with collagen supplements. Without adequate C, collagen cannot properly cross-link.
