99% of the Niacin on the market no longer gives you the flush or hightened blood pressure. Besides if they did use that kind of Niacin it would make them liable if someone with high blood pressure took it and had a heart attack or stroke.
If you have high blood pressure, you should never take any stimulant like 5 hour. However, niacin does not increase blood pressure. It dilates the capillaries and that is what causes the flushing. Slo-niacin or the prescription niacin, niastat, are slow acting and reduce the flushing.
