Yes. In Jainism, non-violence (ahimsa) extends to all animals. Beef and any products derived from cattle are considered harm to living beings, so consuming beef or taking pills containing beef-derived ingredients is generally against Jain teachings. Many Jains also prefer to avoid other animal-derived substances (like gelatin from beef or pork) in medicines and supplements.

Key idea: if a pill or supplement includes meat-derived (beef) components or other animal-derived ingredients, it goes against the Jain principle of ahimsa. Always check labels for animal-derived ingredients and, when in doubt, choose vegetarian or vegan equivalents.
