What it is

Manganese sulfate is a salt that contains manganese, a naturally occurring mineral. It is typically produced industrially by reacting manganese dioxide or manganese carbonate with sulfuric acid. It appears as a white or pale pink crystalline powder.

Why it's used

Manganese sulfate is added to foods as a nutrient to fortify them with manganese. It is commonly found in dietary supplements, infant formulas, and fortified cereals. It helps manufacturers ensure that consumers receive adequate amounts of this essential mineral.

Health notes

In the US, manganese sulfate is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The National Academies of Sciences, Engineering, and Medicine have established a tolerable upper intake level (UL) for manganese. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated manganese and its compounds. While manganese is essential for health, excessive intake can lead to neurological issues, though this is rare from food sources alone.

Allergen info

Manganese sulfate is not derived from any of the nine FDA major allergens and does not contain gluten.
