Many people assume that if a supplement contains vitamins, minerals or plant-based ingredients, it must be vegan. However, some supplements can contain animal-derived ingredients in the capsule, coating, flavouring or active ingredient itself.
If you're following a vegan lifestyle, understanding what to look for can help you make more informed choices.
Quick answer
No, not all supplements are vegan. Common non-vegan ingredients can include gelatin capsules, fish oil, lanolin-derived vitamin D3, collagen, shellfish-derived ingredients and beeswax. Checking the ingredient list and choosing clearly labelled vegan supplements can make shopping easier.
Common non-vegan ingredients found in supplements
You might be surprised to find animal-derived ingredients in:
- Capsule shells, such as gelatin
- Omega-3 supplements, such as fish oil
- Vitamin D3 supplements, such as lanolin from sheep's wool
- Collagen supplements
- Some coatings, flavourings and stabilisers
This is why checking labels or choosing clearly labelled vegan supplements can be helpful.
Why aren't all supplements vegan?
Gelatin capsules
Many capsules are made from gelatin, which is typically derived from animal collagen. Vegan supplements often use plant-based capsules instead.
Fish-derived omega-3
Traditional omega-3 supplements are commonly made from fish oil. Vegan omega-3 supplements are usually sourced from algae instead.
Animal-derived vitamin D
Many vitamin D3 supplements are derived from lanolin, which comes from sheep's wool. Vegan vitamin D options are often sourced from lichen.
Collagen supplements
Traditional collagen supplements are usually derived from animal sources such as bovine or marine collagen.
Vegan collagen products do not contain collagen itself. Instead, they typically contain nutrients and plant-based ingredients that support the body's natural collagen production pathways.
Beeswax and coatings
Some supplements use beeswax in coatings or as a processing aid. While not present in every supplement, it is another ingredient vegans may wish to check for when reviewing labels.

How do I know if a supplement is vegan?
Check the capsule material
Look for plant-based capsules rather than gelatin capsules.
Look beyond the active ingredient
Even when a vitamin or mineral itself is vegan, the capsule, coating, flavouring or added ingredients may not be.
Check for vegan certification or clear labelling
Some brands display vegan certification or clearly state that a product is suitable for vegans.
Review the ingredient list
The ingredient list is often the best place to identify animal-derived ingredients such as gelatin, fish oil, lanolin, collagen, beeswax or shellfish-derived ingredients.
