Lowered my Cholesterol!
My numbers were in the mid-200s when I started this product. Now I'm 100 points lower. Originally, I was on regular niacin, but it caused my whole body to turn brilliant pink and the itching was unbearable, lasting for hours. I've been told this isn't an unusual reaction. I switched to this product and haven't had an issue, even taking it every day. The regular niacin was provided to me free by my insurance, so preferring to buy this is a testament to how well it works.

Great product
I got this product from EBay ( doesn't ship it to Mexico), the doctor prescribed it to me as part of a treatment to adult acné, so far so good, no flush, no secondary reactions, great!
