Niacin
Niacin is vitamin B3. The body needs it to release energy from food and to keep skin, nerves and the digestive system working. At much higher doses it also lowers cholesterol and triglycerides, though that use has declined.
What Niacin Is Used For
- Vitamin B3 deficiency, known as pellagra
- Part of B complex and multivitamin products
- High cholesterol and triglycerides, at prescription strength
- Skin preparations, as niacinamide
Common Side Effects
- Flushing of the face and neck with warmth and tingling
- Itching
- Stomach upset
- Raised blood sugar and liver tests at high doses
Precautions
The flushing is harmless but can be intense, and it is much less pronounced with the niacinamide form used in most supplements. High dose niacin for cholesterol needs medical supervision with liver and blood sugar monitoring, and should not be started on your own. Tell your doctor if you have diabetes, gout, liver disease or a stomach ulcer.
