How much is permitted
A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.
| Japan | — | 1 no quantity stated |
|---|---|---|
| South Korea | — | 1 no quantity stated |
| United States | — | 1 no quantity stated |
No regulator sets a figure for Biotin. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.

Common questions
Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.
- What is Biotin?
- Biotin is vitamin B7, added to infant formula, drinks and fortified foods.
- What is Biotin used for in food?
- It is listed as a sequestrant and a nutrient supplement — the role the US assigns it. This page shows every function each regulator records, with the citation for each.
- Is Biotin banned in Europe?
- No. Biotin does not appear on the EU's list of authorised food additives, which is not the same as being banned: the EU permits an additive only where it has authorised it, and usually the reason for an absence is that no one applied. The EU has made no finding against this substance. It does mean it may not be used as a food additive in the EU today.
- Where is Biotin permitted?
- Of the seven regulators this site reads, Japan, South Korea and the US permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
- Is Biotin vegan?
- Yes. Biotin is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
