My dear friend Niacin was administered orally and Nicotinic acid as Injectable too in the years before 1960 (approx) to reduce cholesterols and triglycerides ie. before the introduction of Clofibrate , and later on statins. Because of the side effects you hv mentioned Niacin was discontinued by the Medical profession. However i take lots of Garlic along with cooked food and green tea extract capsules being marketed online by Protivea.com and i keep my cholesterol levels normal
I am now 71 you too can follow mine. wish you good health
Any
