Listed as a nutrient supplement by the US.
Listed as nutrient supplements (US)
- United States: Nutrient supplement — FDA, Substances Added to Food: VITAMIN A
- United States: Nutrient supplements — 21 CFR 184.1930, citing 21 CFR 170.3(o)(20)
Vitamin A is added to margarine, milk, and infant and fortified foods. As an additive it is usually retinyl palmitate or acetate rather than retinol itself, because the esters keep better.

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 |
|---|---|---|
| United States | — | 1 no quantity stated |
No regulator sets a figure for Vitamin A. 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.
What it is made from
Made by chemical synthesis for fortification use, though vitamin A also occurs naturally in fish liver oils and dairy fat. Preparations are commonly stabilised in a gelatin matrix, which is a dietary question about the preparation rather than the vitamin.

This is not an omission. What this additive is made from is not fixed — depending on the manufacturer it may be plant, animal or microbial in origin, nobody is required to say which, and the same product can change source between production runs. Ask the manufacturer if it matters to you; a label cannot answer it.

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 Vitamin A?
- Vitamin A is added to margarine, milk, and infant and fortified foods. As an additive it is usually retinyl palmitate or acetate rather than retinol itself, because the esters keep better.
- What is Vitamin A used for in food?
- It is listed as a nutrient supplement — the role the US assigns it. This page shows every function each regulator records, with the citation for each.
- Is Vitamin A banned in Europe?
- No. Vitamin A is not on the EU's list of authorised food additives, but it would not be expected to be: every role regulators give it — nutrient supplement — the EU regulates under separate law. Its absence from the additives list says nothing about whether it is permitted in Europe.
- Where is Vitamin A permitted?
- Of the seven regulators this site reads, Japan 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 Vitamin A vegan?
- It depends on the source, and a label will not tell you. Vitamin A can be made from plant or animal material, manufacturers are not obliged to say which, and the same product can change between production runs. Anyone who needs to know has to ask the manufacturer.
