Niacin
Niacin is a B vitamin found in foods and multivitamin supplements. In high doses (available by prescription), niacin lowers triglycerides and raises HDL. Niacin can be offered to people with a high triglyceride level.
High doses of niacin can cause flushing (when your skin turns red), but more recent medications significantly reduce this side effect. Avoiding spicy foods also helps to reduce flushing.
Niacin is not used in people with current indigestion, stomach ache, stomach ulcers, or those at risk of developing these symptoms.
You may also be advised to have periodic blood tests to ensure your liver is functioning well.
