Plant sources do not provide collagen itself — collagen is by definition of animal origin. A 'vegan collagen booster' consists of the building blocks and co-factors the body needs to make collagen itself: amino acids (proline, glycine, lysine — sometimes from pea or rice), vitamin C (essential co-factor), zinc, biotin, copper and sometimes silicon or hyaluronic acid. For those who are consistently vegan.

Why does the body need co-factors?

Collagen synthesis requires specific enzymes that only work with co-factors. Vitamin C is essential for the hydroxylation of proline and lysine — without vitamin C the body cannot make stable collagen. Zinc, copper and silicon play supporting roles. EFSA claim: vitamin C contributes to normal collagen formation for the normal function of skin.

What is in a good vegan collagen booster?

(1) A high vitamin C dose (200-500 mg or more); (2) zinc (8-15 mg); (3) the amino acids proline, glycine and lysine (from plant hydrolysates); (4) optional: biotin (skin), silicon from bamboo extract (connective tissue), hyaluronic acid, coenzyme Q10.

Frequently asked questions

Is a vegan collagen booster as effective as 'real' collagen?

The mechanisms differ. Real collagen provides specific peptides that are measured directly in skin and joints (Iwai 2005). A booster supports the body's own production via co-factors. For consistent vegans the booster approach makes sense; clinical effectiveness at equal dosage is an open question in the literature.

Which vitamins and minerals do I need for collagen synthesis?

Vitamin C (essential), zinc (skin and tissue repair), copper (elastin and collagen cross-linking), silicon (connective tissue). A balanced vegan diet often provides a lot, but targeted supplementation can help.

Do biotin and silicon help hair and nails?

Biotin has a demonstrable effect in genuine deficiency; in people without a deficiency it is less clear. Silicon from bamboo extract has limited but positive studies for hair/nails.

Can I take vitamin C in high doses (>500 mg)?

Safe for most people. Above 1,000 mg, absorption decreases and diarrhoea can occur. Buffered or liposomal forms reduce complaints.
