What is Niacin?
Niacin, or vitamin B3, exists in two main forms: nicotinic acid and niacinamide (nicotinamide). Both serve as precursors to NAD and NADP, coenzymes involved in over 400 enzymatic reactions in the body.
Energy Production
NAD and NADP are essential for converting the food you eat into cellular energy. Every cell in your body depends on these coenzymes for proper function.
Cardiovascular Benefits
Nicotinic acid (but not niacinamide) has been shown to improve cholesterol profiles at therapeutic doses—raising HDL while lowering LDL and triglycerides. However, high doses should only be used under medical supervision.
The Niacin Flush
Nicotinic acid can cause a "niacin flush"—a harmless but uncomfortable warming and reddening of the skin. Flush-free forms are available but may not provide the same cardiovascular benefits.
Food Sources
Meat, poultry, fish, legumes, and fortified grains are excellent sources. Your body can also synthesize niacin from the amino acid tryptophan.
