Timing
Together, with or without food.
How it works
Ascorbic acid is the essential cofactor for prolyl and lysyl hydroxylase, the enzymes that cross-link collagen into functional fibres.
Scurvy — the extreme consequence of Vitamin C deficiency — is fundamentally a collagen synthesis failure. Even mild insufficiency impairs collagen production. As little as 50 mg Vitamin C is sufficient to support the enzymatic reaction.
What to do
Take 50–200 mg Vitamin C with your collagen supplement. More is not necessary for this purpose. Can be taken with or without food.
