On the basis that a plasma pyridoxal 5´-phosphate (PLP) concentration of 30 nmol/L is indicative of an adequate vitamin B6 status, EFSA calculated population reference intakes (PRIs) for vitamin B6 of 1.6 and 1.7 mg/day for women and men respectively, with additional values of 1.8 and 1.7 mg/day for pregnant and breastfeeding women. For children aged 1‑17 years, PRIs ranged between 0.6 and 1.7 mg/day, while for infants (aged 7-11 months), an adequate intake (AI) of 0.3 mg/day was derived.

With regards to potassium, an AI of 3500 mg/day was proposed for adults (with a higher AI of 4000 mg for breast‑feeding women). Extrapolating from this value, AIs for older children ranged from 800 to 3500 mg/day, and an AI of 750 mg/day was set for infants aged 7-11 months.
