Vitamin B3 is also called niacin. It is needed for over 50 body processes. Like all the B-complex vitamins, it is important for release of energy from carbohydrates and fats, the metabolism of proteins, making certain hormones, and assisting in the formation of red blood cells. The term niacin refers to nicotinic acid and nicotine, which are both used by the body to form the coenzymes, NAD (Nicotine Adenine Dinucleotide) and NADP (Nicotine Adenine Dinucleotide Phosphate (NADP). By the way, the names have nothing to do with the nicotine in tobaccos, they are the coenzymes in oxidation-reduction reactions within the human body. They are vital in cell metabolism.

Say you had a great workout today, and you body is screaming for extra energy to finish the day, Niacin will give a green light for the energy system to generate more energy for you.

Vitamin B3 Niacin Recommended Dietary Allowance

The RDA for niacin, revised in 1998, was based on the prevention of deficiency. Pellagra can be prevented by about 11 mg NE/day, but 12 mg to16 mg/day has been found to normalize the urinary excretion of niacin metabolites (breakdown products) in healthy young adults. Because pellagra represents severe deficiency, the Food and Nutrition Board (FNB) chose to use the excretion of niacin metabolites as an indicator of niacin nutritional status rather than symptoms of pellagra. However, some researchers feel that cellular NAD and NADP content may be more relevant indicators of niacin nutritional status.

Daily recommendations for dietary vitamin B3 are listed below.

Children and Youth:

Infants 0-6 months: 2 mg/day
Infants 7-12 months: 4mg/day
Children 1-3 years: 6 mg/day
Children 4-8 years: 8 mg/day
Children 9-13 years: 12 mg/day
Adolescents 14-18 years: 16 mg/day (female) 14 mg/day (male)


Adults 19 years and older: 16 mg/day (female) 14 mg/day (male)
Pregnancy all ages: 18 mg/day
Breastfeeding all ages: 17 mg/day

These are the minimum niacin requirements, while most vitamin supplements provide 50 to 100mg of niacin.
