Why this is a critical point
Stearic acid and its derivative magnesium stearate act as a lubricant in tablet manufacturing and an anti-caking agent in powders. Their source can be palm oil (halal) or animal fat, including pork (needs verification), which is why they frequently appear on the critical-point list for pharmaceutical and supplement products.
Halal alternative
Halal-certified plant-based stearic acid/magnesium stearate, usually from palm oil.
