Is Calcium Stearate Vegetarian?

Caution

Sometimes. Calcium stearate used to be derived from cows or pigs, but is now more likely to come from a vegetable. If you want to be sure, we recommend calling the manufacturer.

Calcium Stearate and the Vegetarian Diet

Calcium stearate is a calcium salt derived from stearic acid, commonly used in the food industry as an anti-caking agent, emulsifier, or stabilizer. It appears as a white, wax-like powder and is often incorporated into powdered foods, spices, and confections to prevent clumping. Historically, calcium stearate was sourced from animal fats, but modern production is primarily from vegetable oils, making it suitable for vegetarians. However, to ensure its vegetarian status, consumers may need to verify the source with manufacturers.
