A study examined the effect of garlic on blood cholesterol levels. A total of 192 subjects with starting low-density lipoprotein (LDL) cholesterol ("bad cholesterol") levels between 130 and 190 mg/dl were randomly assigned to one of four treatments for six months: raw garlic eaten daily, a powdered garlic supplement taken daily (Garlicin brand), an aged-garlic extract taken daily (Kyolic brand), or a placebo pill taken daily. The study found no significant or clinical differences in blood cholesterol levels between the four groups at the end of the study.
