    Test Description

    Vitamin B3 (Niacin)

    Niacin, like the other B vitamins, is necessary for energy production (NAD). It is important in the synthesis of DNA, fatty acids and cholesterol. It is also important in brain function. Niacin is found in brewer's yeast, liver, poultry, peanuts, fish, whole grains, eggs and milk. The nicotinic acid form may dilate blood vessels and cause a "flush."

    A deficiency of niacin may result in inflamed and discolored skin (dermatitis), diarrhea and depression (the three "D's" of Pellagra). Headaches, elevated blood lipids and fatigue may also occur. The RDA for niacin is 16 mgs. A suggested supplemental level is 20 to 1000 mgs. Levels of 3000 mgs have been stated to be toxic.

    Specimen requires 4.0 mL of whole blood collected in a heparin tube. Protect from light, freeze and ship in an amber plastic tube. Vitamin B3 is also known as niacin, nicotinic acid and niacinamide.
