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 vitamin D, magnesium, berberine, or an Ayurvedic herb like 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.

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.

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, or low iron and vitamin D, 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.

Methodology

Every buying guide on Evidence-Based Supplements & Nutrition for India follows the same research and citation workflow. We do not publish anything that fails the checklist below.

Multi-source verification. Every numeric claim — pricing, specifications, performance figures, safety ratings — links to its source. We require at least one official document plus one independent, editorially-trusted source before publishing.

Real-world over claimed. Where official and independent figures diverge, we publish both with the source named. Independently-verified figures are treated as the primary numbers for reader decisions.

Honest weaknesses. Each model review names what it is not good at. Pure positive coverage is a sign of advertorial, not journalism.

No paid placements. We do not take money from manufacturers. No affiliate links to dealer portals. No sponsored top-of-list slots.

Update cycle. Every article carries a Last verified date. Pricing, variants, and ADAS feature lists are re-checked when an OEM updates the model.

Editorial principles

Front-load the answer — first sentence answers the title with a number.

Cite numbers inline; sources surface as a structured section, not a footnote dump.

Acknowledge uncertainty. If the data is thin, we say so.

Direct, declarative voice. No filler. No formulaic section endings.

Comparison tables before walls of prose — buyers scan, then read.
