Collagen and Vitamin C: Why They Work Together

By the Vitamynx team · Reviewed June 2026 · 3 min read

Short answer: your body can’t build collagen without vitamin C. That’s why “collagen with vitamin C” products pair the two, and it’s also why a vegan vitamin-C gummy is a smart way to support collagen without any animal collagen at all.

Why vitamin C matters for collagen

Vitamin C is a required cofactor in normal collagen formation, which is one of the few EU-authorised nutrient claims in this area. In plain terms: collagen powders give your body collagen; vitamin C helps your body make and use its own. Take a collagen supplement without enough vitamin C and you’re missing the cofactor that makes collagen work.

The vegan way: vitamin C + biotin, no animal collagen

Collagen itself is animal-derived, so it’s never vegan. A plant-based route supplies the building blocks instead. Our Biotin Plus gummy pairs vitamin C (for normal collagen formation) with biotin and selenium for hair, skin and nails, in a 100% vegan, Halal-certified, plant-pectin gummy.

These are authorised nutrient claims. No supplement “builds collagen” as a medical claim.

FAQs

Does collagen need vitamin C to work?

Vitamin C is a required cofactor for normal collagen formation, so pairing the two makes sense. A vitamin-C supplement supports your body’s own collagen even without an animal collagen product.

Can I take collagen and vitamin C together?

Yes, they’re commonly combined. If you’re vegan, skip the animal collagen and use a vitamin-C and biotin gummy instead.

Is there a vegan collagen-and-vitamin-C gummy?

Yes. Biotin Plus combines vitamin C, biotin and selenium in a 100% vegan, Halal-certified gummy, with no gelatine and no animal collagen.
