I have read that fasting has no effect on Lp(a). I know that it doesn't help mine which was 125 mg/dl. I am 52, and the doctors who have checked my neck and heart seem to think that they sound OK. In any event, I have been taking 2000 mg of C for at least 26 years. A dentist who later committed suicide put me on it. I have also read about the Linus Pauling Protocol of taking 3000 mg of Vitamin C and 3000 mg of L-lysine which I am taking spaced out. Sadly, I didn't even know about the Lp(a) until this year. I have also taken Vitamin D at 5000 iu for several years and high dose fish oil. I have tried to stay fit. I was able to reverse pre-diabetes for several years although it has been creeping up slightly with Statin use.
