came upon some information and didn't really understand what it meant?:

coenzyme Q10 shares a common biosynthetic pathway with cholesterol. The synthesis of an intermediary precursor of Coenzyme Q10, mevalonate, is inhibited by some beta blockers, blood pressure-lowering medication,[20] and statins, a class of cholesterol-lowering drugs.[21] Statins can reduce serum levels of coenzyme Q10 by up to 40%.[22] Some research suggests the logical option of supplementation with coenzyme Q10 as a routine adjunct to any treatment that may reduce endogenous production of coenzyme Q10, based on a balance of likely benefit against very small risk.

does this mean that coq10 affects efficacy of beta blockers, or beta blockers affects absorption of coq10?
