What is it about?

This review is on the bacterial biosynthesis of retinoids from carotenoids dependent and independent pathway. In particular, this review highlights the scientific predictions that are underpinning the hypothesis “Biosynthesis of retinoids from carotenoids dependent and independent pathways through gut microbiota

Why is it important?

A current worldwide issue and still an inexcusable scenario about the vitamin A deficiency (VAD) is about one-third of children aged 6–59 months is still affected by this illness. Finding the viable alternaties with ethical concenr and people acceptability is need of the hour research area.


This review aims to focus exclusively on bacterial metabolism of retinoid and carotenoid and revealed some natural and viable approaches such as probiotics and synbiotic foods for VAD.
