Statins to control the "normal" cholesterol levels (which weren't bad to begin with), and I've found that my Lp(a) number went down a little after I started CoQ10, which is something that's been found in experimentation as well - https://pubmed.ncbi.nlm.nih.gov/26836888/

I keep trying to get into one of the Cleveland Clinic trials for the drugs that rewrite your liver's instructions to prevent it from making Lp(a), but I haven't had much success with timing so far. If I do get into one of those trials, I want to get a tattoo with a "Genetically Modified Organism" logo :-D
