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. This guide covers Vitamin B Complex from first principles: what it is, what the evidence says, and how to use it safely in an Indian context.

Buying guide for India
When shopping on Amazon.in, prioritise products that clearly state:

Vitamin B Complex has Key citations: PMID 20688574, PMID 16531613, PMID 20838622 for Fatigue. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
