E633: Calcium Inosinate
Main role: flavor enhancement
Also listed as: calcium 5'-inosinate
What is E633 (Calcium Inosinate)?
Calcium inosinate is a calcium salt of inosinic acid. Its principal additive role is enhancing savory flavor, often alongside other flavor ingredients.
What does it do in food?
Its main role is flavor enhancement. Flavor enhancement changes how a recipe tastes. It does not replace the food’s protein, vegetables, or other nutrients. Salt and other seasonings may still be present, so compare the complete label.

Label names and ingredient questions
Look for E633, E 633, or the ingredient name. Related names and label terms include calcium 5'-inosinate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Calcium inosinate is not a calcium supplement claim. The amount used for flavor does not provide a reliable estimate of calcium intake.
Is E633 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E633 as Calcium inosinate. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
