2 verifications about Cholesterol Cholesterol ×
“Red yeast rice lowers cholesterol levels in humans.”
Clinical evidence strongly supports that red yeast rice preparations containing meaningful amounts of monacolin K lower LDL and total cholesterol in humans, with meta-analyses of randomized controlled trials showing 15–25% LDL reductions. However, the claim requires an important caveat: monacolin K content varies widely across commercial products, and in the U.S., products with substantial monacolin K face FDA restrictions as unapproved drugs. Not all retail red yeast rice supplements will reliably produce cholesterol-lowering effects.
“Higher cholesterol levels in the body lead to higher testosterone production.”
While cholesterol is a necessary biochemical precursor for testosterone synthesis inside cells, the claim that "higher cholesterol levels in the body" lead to higher testosterone production is not supported by human evidence. Multiple population-level studies (including NHANES data) find no association—or even an inverse relationship—between circulating cholesterol and testosterone levels. The rate-limiting step is intracellular cholesterol transport into mitochondria, not the amount of cholesterol in the bloodstream. Research also shows that low testosterone can itself raise circulating cholesterol, reversing the claimed causal direction.
