Niasin – Mayo Clinic

Overview
Niacin is a vitamin B that the body does. The body uses niacin to convert food into energy. It helps to keep the nervous system, the digestive system and the skin healthy.
People can take the niasini, also called vitamin B-3 as part of daily multivitamine. However, most people get enough of the food they eat. Niacin -rich foods contain yeast, milk, meat and grain.
Some people use prescription niacor (niacor) to help manage cholesterol.
The amount of daily niacin recommended for adults appointed at birth is 16 milligrams per day (mg). For adults assigned for women who are not pregnant at birth, the dose is 14 mg per day.
What does the research say
Research on the use of niacin that you receive orally to treat certain conditions:
- High cholesterol. The prescription niacin raises high -density lipoprotein (HDL) cholesterol. This is a “good” cholesterol that helps to remove “bad” cholesterol from blood. Although Niacin can increase HDL cholesterol, research shows that Niacin treatment is not lower than lower death, heart attack or stroke rates.
- Niacin deficiency, also called Pellagra. A nutrient called niacin and niasinamide treats or prevents niacin deficiency. This is not common in the United States.
