Little information is available regarding the dietary vitamin B5 intakes and related health consequences in humans. As there are only limited data on the pantothenic acid requirements the European Scientific Committee for Food has not established a dietary reference value (DRV, recommended intake). Average intakes in adults are about 4–7 mg/day, with a range of 3–12 mg/day. Such intakes were considered adequate to prevent deficiency, including during pregnancy and breast-feeding (11).
In 2014, the European Food Safety Authority (EFSA) recommended the adequate intake (AI) of vitamin B5 for adult men and women, including pregnant women, should be set at 5 mg per day. For lactating women, an AI of 7 mg per day was proposed to compensate for pantothenic acid losses through breast milk. For infants over six months, an AI of 3 mg/day was proposed and the AIs for children and adolescents were set at 4 and 5 mg/day (33).
As the U.S. Food and Nutrition Board of the Institute of Medicine (IOM) felt the existing scientific evidence was insufficient to calculate a recommended dietary allowance (RDA) for vitamin B5, they set an AI for pantothenic acid in 1998, based on estimated dietary intakes in healthy population groups (12):
|Life Stage||Age||Males: (mg/day)||Females: (mg/day)|
|Adults||19 years and older||5||5|
