Recommended daily allowances (RDAs) are defined as the levels of intake of essential nutrients that the Food and Nutrition Board at the Institute of Medicine has found to be adequate to meet the known nutrient needs of most healthy persons.

Specific recommendations for each vitamin depend on age, gender, and other factors (such as pregnancy). The general recommended intakes for niacin are listed below:

Infants

• 0-6 months: 2 milligrams per day (mg/d)
• 7-12 months: 4 mg/d

Children

• 1-3 years: 6 mg/d
• 4-8 years: 8 mg/d
• 9-13 years: 12 mg/d

Adolescents and Adults

• Age 14 and up: 14 mg/d
• Pregnant women: 18 mg/d
• Breastfeeding women: 17 mg/d

The best way to get the daily requirement of essential vitamins is to eat a balanced diet that contains a variety of foods from the food guide pyramid.
