Is steroid vegan?

A steroid is an organic compound with a specific four-ring carbon molecular structure, commonly appearing on ingredient lists in dietary supplements, fitness formulations, and certain fortified foods. When listed on retail food or supplement products, the term usually refers to sterols, hormones, or related lipid derivatives that have been isolated from natural biological materials or synthesized in a laboratory.

This ingredient is classified as possibly vegan because it can be derived from either animal or plant origins, and labels rarely specify the starting material. Plant-derived steroids are typically extracted from vegetable oils, soy, pine wood pulp, or grains. Animal-derived varieties can be sourced from cholesterol extracted from lanolin found in sheep wool, slaughterhouse tissues, or animal bile. Synthetic versions may also rely on chemical precursors from either source. Because the chemical structure can be identical regardless of origin, consumers must look for a certified vegan label or contact the manufacturer to verify the source.
