Is Calcium Citrates (E333) Halal?

MUIS lists E333 (Calcium Citrates) as doubtful (mashbooh), which means the source cannot be confirmed from the E-number alone — not that it is haram. It is produced by fermentation, and the fermentation medium, nutrients and processing aids vary by manufacturer and can include animal-derived ingredients. The additive itself is not haram; its status depends on how the producer makes it. The reliable check is a recognised halal certification logo on the finished product, or a manufacturer statement of the source.

Calcium citrates are calcium salts of citric acid, used as firming agents, calcium fortifiers and acidity regulators. They are produced by reacting citric acid with calcium carbonate or hydroxide.

• infant formula
• supplements
• fresh-cut fruits

• Look for a recognised halal certification logo (MUIS, JAKIM, MUI, HMC or similar) on the packaging — certified products have had the source of this additive verified.
• Check whether the label states the origin, for example 'vegetable origin', 'plant-based' or 'soy'.
• If there is no certification and the origin is not stated, contact the manufacturer or choose a product with a halal alternative.
