What amount niacin should i take?

None: You're 38. What is your indication for taking niacin? If you have high cholesterol, change your diet and life style.

Dr Munshower agreed

Niacin.: Supplementing with 2000-3000mg of flush free Niacin daily can help to control your cholesterol levels quite nicely, even increasing your HDL and converting your LDL to a less harmful subtype. As a negative, Niacin can cause facial flushing and redness so get the flush free variety. And have your liver enzyme values monitored, as they can be affected by Niacin use.
