    Skin flushing has been reported above 35 mg of Niacin or Nicotinic acid. However, there is no toxicity below 2000 mg of Niacinamide. People with a history of liver disease, diabetes, peptic ulcers, gout, inflammatory bowel disease, migraine headaches or alcoholism are more susceptible to the adverse effects of excessive nicotinic acid intake.
