Query: What Were They Thinking?

This product is normally used to help reduce LDL cholesterol and triglycerides; however, one of the ingredients listed on the label is Hydrogenated Vegetable Oil, a known cause of cardiovascular disease!What were they thinking?!This product may be more beneficial than harmful, but why use a product that contains small quantities of trans-fats? There has to be a better source of Niacin.Also, don't overdo this or any form of Niacin (Nicotinic Acid). In large doses, it can cause liver damage.
