My cardiologist and general practitioner both told me vitamin D helps either reduce bad cholesterol, increase good cholesterol or both, so I started taking it. I’d like to verify this info when I have time...
I believe that the same can be said for red wine! But I am absolutely positive that Vitamin B3, Niacin, in the form of nicotinic acid, the kind that causes flushing at first, will increase the good cholesterol, and reduce the bad, as well as reduce triglycerides, if taken at 2000 mg per day level. (I weigh 175 lb. 1500 mg did not quite work for me.) The flushing can be eliminated by taking a non-enteric coated aspirin for a while, then that can be discontinued after a few days.
