Is collagen vegan?
Why
collagen is made by boiling the skin, bones and connective tissue of pigs and cattle — a slaughterhouse by-product.
Commonly hides in
- custard
What to use instead
pea protein — It does exactly the same job in coffee, cooking and baking, with no change in method.
How to check a label
Ingredient lists are legally required to name allergens such as milk and egg in bold, which catches most hidden animal ingredients. E-numbers and processing aids are the gap: E120, E441, E542, E904 and E920 are animal-derived, and processing aids often go unlisted. When in doubt, look for a certified vegan mark or ask the manufacturer directly — most reply within a few days.
In depth
The longer answer
Collagen is a structural protein found in the connective tissues of animals, including skin, bones, tendons, and ligaments. It is commonly sourced from bovine hides, fish scales, and porcine skin, then hydrolyzed into a powder for supplements and food products. Because it is derived exclusively from animal parts, traditional collagen is not vegan and is often promoted for skin, joint, and bone health.
The vegan status of collagen is complicated by the existence of plant-based alternatives. Some products claim to be "vegan collagen" but are actually collagen boosters—ingredients like vitamin C, silica, and amino acids that support the body's own collagen production. True vegan collagen, produced via genetically engineered yeast or bacteria, is emerging but still rare and expensive. Most commercial collagen supplements remain animal-derived.
To verify if a collagen product is vegan, check the ingredient list for terms like "hydrolyzed collagen," "gelatin," or "bovine/porcine/fish collagen." Look for labels explicitly stating "vegan" or "plant-based." Alternatively, consider whole-food sources of collagen-supporting nutrients, such as citrus fruits for vitamin C, nuts for copper, and legumes for amino acids. These can help your body produce collagen naturally without animal ingredients.

In practice
What this means for you
- Check labels for "hydrolyzed collagen" or "gelatin"—both are animal-derived.
- Look for supplements labeled "vegan collagen builder" instead of just "collagen."
- Boost your own collagen with vitamin C-rich foods like bell peppers and strawberries.
- Avoid products with "bovine," "porcine," or "fish" in the ingredient list.
