Vitamin D2 inactive bakers yeast
Vitamin D2 inactive bakers yeastVitamin D2 inactive baker's yeast is baker's yeast that has been exposed to ultraviolet light, which turns the ergosterol in its cells into vitamin D2, and then heat-killed. FDA listed it in September 2026 as a source of vitamin D2 in named foods, among them breakfast cereals, plant-based milk and yogurt alternatives, soy products, soups and yeast-leavened baked goods, at a stated maximum for each.
Where it is and isn’t permitted
| Jurisdiction | Status | Scope and limits | Citation |
|---|---|---|---|
| Australia and New Zealand | No listed food uses foundThis site has not matched this substance to any food use on this jurisdiction’s list of authorised food additives. A food additive may be used only in foods that list names. Flavourings, enzymes, processing aids and added nutrients are regulated separately and do not appear on it. | ||
| Canada | No listing matchedHealth Canada’s lists name additives without E or INS numbers, so this site matches them by exact name. A substance listed there under a name this site does not recognise has no row here. | ||
| European Union | No listed food uses foundThis site has not matched this substance to any food use on this jurisdiction’s list of authorised food additives. A food additive may be used only in foods that list names. Flavourings, enzymes, processing aids and added nutrients are regulated separately and do not appear on it. | ||

| Japan | No listing matchedThis site imports only Japan’s list of designated additives (Appended Table 1 to the Regulations for Enforcement of the Food Sanitation Act), matched by English name. Existing additives, natural flavouring agents and ordinary foods used as additives are permitted outside that list and are not imported, so an empty row does not show that Japan does not permit the substance. | ||
| South Korea | No listing matchedThis site imports Part III of South Korea’s Standards and Specifications for Food Additives, matched by CAS number, then INS number, then exact name. Mixed preparations and sanitisers are not imported, and an entry whose identifiers disagreed with a page’s is held for review, so an empty row does not show that South Korea does not permit the substance. | ||

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.

No regulator sets a figure for Vitamin D2 inactive bakers yeast. 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.
Regulatory changes
Dated acts affecting this additive, then anything the weekly comparison of the imported lists has seen move. The status panel above shows where the rules stand now; these are the decisions that got them there.
· United States
FDA lists vitamin D2 inactive baker's yeast as a source of vitamin D2 in named foods, effective 25 September 2026
The final order at 91 FR 60796 amends the food additive regulations, adding 21 CFR 172.383, in response to a petition from Lallemand Inc. (Docket FDA-2021-F-1157). It permits vitamin D2 inactive baker's yeast as a source of vitamin D2 in listed food categories, each with its own maximum level of vitamin D2, stated per 100 g, per serving or per 240 mL according to the food. The yeast must meet the specifications the section sets. The order took effect on publication, 25 September 2026. Objections and requests for a hearing are due by 26 October 2026.
Differences the refresh found
Each import is compared with the one before. These are the differences seen, dated by when the comparison ran — not by when they took legal effect, which the lists do not say. Nothing here is interpreted; the provisions and their citations are in the panel above.
· United States
United States status changed from not listed to permitted with conditions; 1 provision added.
- Added — no quantity stated
What it is made from
Baker's yeast, Saccharomyces cerevisiae, is irradiated with ultraviolet light, which converts the ergosterol it makes into vitamin D2 (ergocalciferol), and is then inactivated with heat. It can be used alone or alongside ordinary baker's yeast. The regulation sets limits for moisture, for several micro-organisms and for lead, arsenic, cadmium and mercury.

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 D2 inactive bakers yeast?
- Vitamin D2 inactive baker's yeast is baker's yeast that has been exposed to ultraviolet light, which turns the ergosterol in its cells into vitamin D2, and then heat-killed. FDA listed it in September 2026 as a source of vitamin D2 in named foods, among them breakfast cereals, plant-based milk and yogurt alternatives, soy products, soups and yeast-leavened baked goods, at a stated maximum for each.
- Is Vitamin D2 inactive bakers yeast banned in Europe?
- No. Vitamin D2 inactive bakers yeast 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 Vitamin D2 inactive bakers yeast permitted?
- Of the seven regulators this site reads, the US permits 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 D2 inactive bakers yeast vegan?
- Yes. Vitamin D2 inactive bakers yeast is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
