What it is
A B-vitamin essential for hair, skin and nail health.
Why depends
Most commercial biotin is synthetic or fermentation-derived. A handful of 'whole-food' supplements list 'egg yolk biotin' — avoid those.
What a “Depends” verdict means
A 'depends' verdict means the same ingredient name covers both plant and animal sources, and the label alone cannot tell you which one is in the tub. Certification, an allergen statement, or a direct answer from the manufacturer is the only reliable way to settle it.
Where you'll find it
- Hair-and-nails supplements
- Multivitamins
- Fortified foods

How to read the label
Biotin (B7) belongs to the vitamins and supplements family. These are the terms worth scanning for on any ingredient list in this category:
- Cholecalciferol
- Vitamin D3
- Lanolin
- Gelatine capsule
- Fish oil
- Omega-3
- Shellac coating
- Stearic acid
- Prefer D2 (ergocalciferol) or D3 explicitly labelled 'from lichen'.
- Look for 'vegetarian capsule', 'HPMC' or 'pullulan' on the shell.
- Choose algal oil for EPA and DHA rather than fish or krill.
- Check tablet coatings — shellac and carnauba are both used, only carnauba is vegan.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| Fortified plant milk | The added D can still be lanolin D3. Brands that use lichen say so prominently. |
| Multivitamin gummies | Gelatine base plus beeswax polish is the standard formulation. |
| Magnesium stearate | Usually vegetable but can be tallow-derived; ask if it matters to you. |
Vitamins and supplements in context
Fortification quietly reintroduces animal ingredients into otherwise plant-based food. Vitamin D3 is conventionally made from lanolin in sheep's wool, omega-3 from fish oil, and some vitamin A and E preparations use animal-derived carriers.
Plant-based routes exist for nearly all of them: lichen-derived D3, algal DHA and EPA, and synthetic or vegetable-sourced tocopherols. They cost more, so the default in cheap fortified products is the animal route.
Capsule shells matter as much as the contents — most soft-gel and many hard capsules are gelatine, while vegan supplements use HPMC (hydroxypropyl methylcellulose) or pullulan.
Does certification help? Supplements are a category where vegan certification genuinely pays: it covers both the active ingredient source and the capsule shell, which the ingredient panel often obscures.

FAQ
- Do vegans need extra biotin?
- Rarely — peanuts, almonds, sweet potato and seeds all provide it.
- Is vitamin D3 always non-vegan?
- No. Lichen-derived D3 is chemically identical and fully plant-based; it is labelled explicitly because it costs more.
- Do vegans need B12 supplements?
- Yes. Reliable B12 comes from fortified foods or supplements, and cyanocobalamin is produced by bacterial fermentation, so it is vegan.
