Estimated Dietary Intakes of Vitamin A5

This study investigates dietary intake levels of Vitamin A5—a newly identified vitamin critical for mental health and neurological function—in Western countries. Vitamin A5, mainly derived from 9-cis-beta-carotene in fruits and vegetables, is vital for RXR signaling in the brain. Findings show that most populations in Western Europe consume less than the recommended 1.1 mg/day of Vitamin A5, with Italy having the highest intake and Austria the lowest. The study suggests fortification and supplementation to bridge this nutritional gap.
