Daily Vitamin Intake Chart - An Introduction to Vitamin Dosage

The following table outlines the recommended daily intake of vitamins and minerals, as set forth by the Food and Nutrition Board of the American Institute of Medicine (other countries have similar guidelines). The amounts listed are for healthy adults averaging 2,000 calories per day. Amounts vary for children, seniors, lactating or pregnant women, smokers, heavy alcohol drinkers, stressed or those requiring depression supplements, those with chronic diseases or those who consume less than 2,000 calories per day.

The Recommended Dietary Allowance (RDA) is the minimum amount required to avoid a deficiency. Recently, some of these figures were updated with a Dietary Reference Intake (DRI), which lists the amount required for optimal health (some experts still believe these have been set too low).

Not all nutrients have a DRI established. If no DRI or RDA has been determined, a Safe and Adequate Intake or Range (or estimate) is provided.
