Likely Effective for...
- High cholesterol. Only niacin seems to lower cholesterol, not niacinamide. Some niacin products are FDA-approved prescription products for treating high cholesterol. These prescription niacin products typically come in high strengths of 500 mg or higher. Dietary supplement forms of niacin usually come in strengths of 250 mg or less. Since very high doses of niacin are required for high cholesterol, dietary supplement niacin usually isn't appropriate.
- Treatment and prevention of niacin deficiency, and certain conditions related to niacin deficiency such as pellagra. Both niacin and niacinamide are approved by the U.S. Food and Drug Administration (FDA) for these uses. Niacinamide is sometimes preferred because it doesn't cause "flushing," (redness, itching and tingling), a side effect of niacin treatment.
Possibly Effective for...
- Osteoarthritis. Taking niacinamide seems to improve joint flexibility and reduce pain and swelling. Some people who take niacinamide might be able to cut down on standard painkilling medications.
- Alzheimer's disease. People who consume higher amounts of niacin from food and multivitamin sources seem to have a lower risk of getting Alzheimer's disease than people who consume less niacin. But there is no evidence that taking a stand-alone niacin supplement helps to prevent Alzheimer's disease.
- Hardening of the arteries (atherosclerosis).
- Reducing the risk of a second heart attack in men with heart or circulatory disorders.
- Diarrhea from an infection called cholera.
- Diabetes, types 1 and 2.
- Prevention and treatment of cataracts, an eye condition.
