Vegan Collagen vs Real Collagen: Label Differences
By Glow Nutrition1 min read
Who this is for: UK buyers comparing vegan collagen-support products with marine or bovine collagen
The word collagen can mean two different things
Marine and bovine collagen products usually contain hydrolysed collagen peptides from animal sources. Vegan collagen products usually do not.
Instead, they tend to contain nutrients positioned around collagen formation or beauty support. That can be legitimate if the wording is precise, but it is not the same ingredient.
The label question
Ask: "Does this product contain collagen, or is it a collagen-support formula?"
Vitamin C has authorised wording for normal collagen formation for the normal function of skin. Biotin and zinc have authorised skin or hair wording. Zinc has authorised normal-nails wording. Those claims belong to the nutrients.
For claim wording, read Vitamin C and Collagen Formation.
Claims note
This article does not claim vegan collagen or animal collagen improves skin, hair, nails or joints. Collagen itself has no authorised GB health claim, and nutrient claims must stay attached to the authorised nutrient.

- Most products sold as vegan collagen are collagen-support formulas, not animal-derived collagen peptides. Check the label.
- Can vegan collagen make collagen claims?
- Any claims still need to comply with GB nutrition and health claims rules and should be attached to authorised nutrients where relevant.
