Is Magnesium Lactate (E329) Halal?

MUIS lists E329 (Magnesium Lactate) 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.

Magnesium lactate is the magnesium salt of lactic acid, used as a magnesium source and acidity regulator. The doubtful classification reflects lactic acid's typical whey origin.

• supplements
• limited food applications

• 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.
