Why People Avoid Calcium Stearate

People on corn-free diets may avoid calcium stearate because it can be manufactured using stearic acid or processing aids derived from corn. Since the source of stearic acid is not always disclosed on labels, individuals with corn sensitivities or allergies are advised to contact manufacturers to ensure the product is safe for their dietary needs.

Potential Reactions
