Can I Take collagen with vitamin c?

SUMMARY:

There are no known clinically significant interactions between typical oral collagen supplements and vitamin C; vitamin C is often taken together with collagen because it helps support collagen formation. For most people this combination is considered likely safe when used at common supplement doses.

ADDITIONAL NOTES:

Vitamin C is a cofactor in collagen synthesis and is commonly co-administered with collagen supplements. No direct pharmacologic interactions are reported between standard oral collagen products and vitamin C. Possible considerations: high-dose vitamin C (several grams/day) can cause gastrointestinal upset and may increase oxalate in susceptible individuals, and collagen supplements can occasionally cause mild GI symptoms or allergic reactions; people with kidney disease, a history of kidney stones, or taking prescription medications (especially high-risk drugs like anticoagulants) should check with a provider before starting new supplements.
