Yes, this is true. I was just pointing out a B3 vitamin straight Niacin Nicotinc Acid (Not Niacinamide.) Niacinamide is metabolized differently, and does not do anything with Cholesterol.
Also true high cholesterol indicates underlying problems within the body.
Dachise, clean up your diet. Cut out carbs, and sugar eat meat, fat, vegetables (organic preferred). Supplement with Vitamins and Minerals and your cholesterol will lower as your body repairs itself.
