Health Watch | Nutraceuticals: Nano tech, big benefits

India’s nutraceutical industry is beginning to experiment with nanotechnology, with several companies recently launching high-absorption curcumin, Vitamin D, Omega-3 and herbal supplements. This reflects a larger trend in preventive healthcare, where nutrition is becoming more science-driven and targeted rather than generic supplementation.

Nano-nutraceuticals are essentially nutrients or plant compounds delivered using nano particles, nano-emulsions or nano-capsules that improve the way the body absorbs them. Many popular health ingredients such as turmeric, resveratrol and iron have low absorption in their normal form. Nano-delivery systems can boost bioavailability significantly, meaning smaller doses could be more effective.

In India, this technology is being explored not just for supplements but also for functional foods, immunity drinks and fortified foods. Startups and nutraceutical manufacturers are focusing on nano-curcumin, nano-vitamins, herbal extracts and antioxidant formulations aimed at lifestyle diseases, ageing, immunity and metabolic health. The nutraceuticals market was worth some $6 billion (Rs 55,957 crore) in 2024 and could be worth double by 2030.

For consumers, the long-term significance is important. As India faces rising diabetes, heart disease and obesity, nano-neutraceuticals could make preventive nutrition more effective, personalised and medically relevant—potentially blurring the line between food and medicine in the coming decade.
