About Evidence-Based Supplements & Nutrition for India

What this site is

Nano Health Insights is an independent, evidence-first guide to supplements, nutrition, and everyday health for readers in India. A lot of health advice online is either selling something or lifted from a US blog that ignores how Indians actually eat, what's on the shelf at the local pharmacy, and which deficiencies are common here. We start from the research instead.

For any topic, whether it's a mainstream nutrient like magnesium or vitamin D, a well-studied compound like berberine or curcumin, or an Ayurvedic herb like Arjuna or ashwagandha, we look at what the clinical studies show, where the evidence is strong, and where it's thin or mixed. If something works, we say so. If it doesn't, or the data isn't there yet, we say that too.

A lot of our guides are comparisons rather than single verdicts, because that's usually the real question: magnesium glycinate versus citrate versus oxide, white kidney bean versus mulberry DNJ for carb blocking, which probiotic strain actually helps IBS-related bloating. We also spend time on label-reading itself, since a big part of buying supplements in India is telling a genuinely chelated, non-buffered, or properly dosed product apart from one that just has a bigger number on the front of the pack.

How we source

We rely on primary and high-authority sources: peer-reviewed journals, the Indian Council of Medical Research (ICMR) and the National Institute of Nutrition (NIN), the WHO, the NIH Office of Dietary Supplements, and Cochrane reviews. When we cover a traditional remedy, we describe it accurately within Ayurveda and then check it against modern evidence, rather than treating "natural" as proof on its own.

Where relevant, we also look at what Indian buyers are actually discussing and finding on supplement forums and communities, since that surfaces real problems (mislabelled products, poor absorption, formulations that don't match the science) that a clinical trial alone won't tell you. That's a supplement to the research, not a substitute for it.

We write in plain language, flag safety issues and drug interactions, and revise articles as the science moves. The sources behind each piece are linked so you can read further.

Who it's for

This is for anyone in India trying to make sense of the supplement aisle and the advice that comes with it: people managing common conditions like type 2 diabetes, thyroid problems, PCOS, low iron and vitamin D, joint pain, or gut issues like bloating and IBS, and anyone who just wants to know whether the thing they're about to buy is worth the money.

A note on scope: Nano Health Insights is for general information, not medical advice. Talk to a doctor or a registered dietitian before starting a supplement or changing any medication, especially if you're pregnant, taking prescription drugs, or managing a health condition.
