Natural Factors Vitamin B3 offers 500 mg of vitamin B3 as nicotinic acid per serving. It is a co-factor for enzymes that are vital to energy production and it helps the body convert carbohydrates, fats, and proteins into energy*. Vitamin B3 is also vital to normal growth and development*.

Vitamin B3 also supports cardiovascular health by acting as a potent vasodilator, which means it expands blood vessels to increase the flow of blood. As a result, niacin can sometimes cause an uncomfortable flushing effect, with itching, burning, or tingling in the skin. This is thought to be an important part of niacin's therapeutic value on the circulatory system and these symptoms do not last*.
