Niacin, fatty fish like salmon or tuna, omega 3 or flaxseed oil capsules, mono unstaturated sources of oils like olive or canola, nuts such as almonds, walnuts and pistachios and small amounts of alcohol have been confirmed to raise HDL. Excercise may help also but the jury's is out on this. Take your your pick.

I manage to do all the above, keep my weight in bounds and HDL around 65- hot damn.
