Melatonin: complete India guide

India has one of the highest rates of micronutrient deficiency in the world — and the supplement market is growing fast to meet it. But with hundreds of products on Amazon.in and little regulation, knowing what to actually buy is harder than it should be.

Bottom line

Melatonin has Key citations: PMID 27655070 (Ferracioli-Oda 2013, insomnia meta-analysis), PMID 22453634 (Costello for Sleep onset difficulty. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
