Life Stage Group

AI (mg/d)

Basis for AI

0–6 mo

1.7

Human milk content

7–12 mo

1.8

Mean of extrapolation from AI for 0–6 mo and adult AIb

1–3 y

2

Extrapolation from adult AI

4–8 y

3

Extrapolation from adult AI

9–13 y

4

Extrapolation from adult AI

14–18 y

5

Extrapolation from adult AI, urinary pantothenate excretion

≥ 19 y

5

Usual intake

Pregnancy, all ages

6

Usual intake

Lactation, all ages

7

Usual intake, maternal blood concentrations, secretion of pantothenic acid into milk

a Unless noted otherwise, all studies were performed in the United States or Canada.

b To extrapolate from the AI for adults to an AI for children, the following formula is used AIchild = AIadult (F), where F = (Weightchild/Weightadult)0.75 (1 + growth factor). To extrapolate from the AI for infants ages 0–6 months to an AI for infants ages 7–12 months, the following formula is used: AI7–12mo= AI0–6mo (F), where F = (Weight7–12mo/ Weight0–6mo)0.75.
