Roll Call does not check drug interactions or assess personal safety.
A waxy, fat-like substance the body makes on its own and also gets from animal foods such as eggs, meat, and dairy. As a supplement ingredient it is typically animal-derived (sometimes from wool grease or egg yolk) and appears in only a small number of specialty products, rather than as a standalone pill most people would recognize.
Why it’s used
Cholesterol is a building block for cell membranes, hormones, and vitamin D synthesis in the body, but it is rarely added to supplements as something people take to get more of — most diets already supply it, and the body also manufactures its own. When it does show up in a supplement formula, it is usually incidental to another ingredient (such as a lipid extract) rather than the intended active.
What the evidence says
There is no mainstream body of evidence for supplemental cholesterol as something taken for a health effect, because it is not typically marketed or studied that way. NIH ODS does not maintain a fact sheet on cholesterol as a dietary supplement; the large evidence base on cholesterol concerns blood cholesterol levels and cardiovascular risk, which is a different question from an ingredient listed on a Supplement Facts panel.

Context
Where cholesterol appears on a label, it is worth checking whether it is the stated ingredient itself or simply a natural component of another listed ingredient, such as a lecithin or animal-fat-derived extract.
