Uses of Niacin

USES:
Niacin is used in addition to a proper diet and exercise to help control levels of fats in the blood. It can help lower "bad" cholesterol and fats (e.g., LDL, triglycerides) and raise "good" cholesterol (HDL). In general, this drug is used after your blood fat levels have not been fully controlled by other treatment (e.g., diet changes, exercise, decreasing alcohol intake, stopping smoking, weight loss if overweight, and controlling blood sugar if diabetic). It may be used with or without other medications.

Lowering "bad" cholesterol/triglycerides and raising "good" cholesterol may help decrease the risk for strokes and heart attacks. Lowering fats may also help reduce the risk of pancreas problems (pancreatitis) in people at risk. Niacin is also known as vitamin B-3 (nicotinic acid), one of the B-complex vitamins.

Uses of Niac

Niac is also known by the generic name Inositol Niacinate

Niac is also known by the generic name Niacin

USES:
Niacin (nicotinic acid) is used to prevent and treat niacin deficiency (pellagra). Niacin deficiency may result from certain medical conditions (e.g., alcohol abuse, malabsorption syndrome, Hartnup disease), poor diet, or long-term use of certain medications (e.g., isoniazid).

Niacin deficiency can cause diarrhea, confusion (dementia), tongue redness/swelling, and peeling red skin. Niacin is also known as vitamin B3 , one of the B-complex vitamins. Vitamins help to support the body's ability to make and break down natural compounds (metabolism) needed for good health. Niacinamide (nicotinamide) is a different form of vitamin B3 and does not work the same as niacin. Do not substitute unless directed by your doctor.
