Niacin-SR provides niacin in a sustained-release matrix that releases slowly over several hours. Slow release of niacin helps minimize the uncomfortable flushing action of this B-vitamin that may occur when high-potency amounts are ingested.
Niacin is a B vitamin that's made and used by your body to turn food into energy. It helps keep your nervous system, digestive system and skin healthy.
Niacin (vitamin B-3) is often part of a daily multivitamin, but most people get enough niacin from the food they eat. Foods rich in niacin include yeast, milk, meat, tortillas and cereal grains.
People use prescription niacin (Niacor, Niaspan) to help control their cholesterol.
