Have you noticed how supplements have gone from “only when you’re sick” to “daily must-haves”?

India’s nutrition game is changing — and fast. With more people becoming health-conscious and juggling hectic lifestyles, popping a multivitamin or adding probiotics to your routine feels almost… normal.

In fact, the Indian supplement market is booming, valued at nearly USD 43 billion in 2024 and expected to touch over USD 68 billion by 2030. (1) What’s driving this shift? A younger, urban population that’s thinking long-term about energy, immunity, and gut health. And let’s not forget the COVID-19 wake-up call, pushing immunity boosters, multivitamins, and probiotics to the top of everyone’s shelf.

But here’s the thing – taking supplements is one thing. Taking them right is a whole different game.

The timing, what you eat with them, and even what you avoid pairing them with can make a big difference in how your body actually absorbs and uses those nutrients.

Here’s your nutritionist-approved guide to making sure your supplements actually work for you. (2,3,4,5)
