Marine Medicine: How ICAR-CMFRI's Seaweed Nutraceuticals Are Revolutionising Natural Immunity in 2026
Digital Desk
Indian scientists develop seaweed-based nutraceuticals targeting immunity, diabetes and arthritis. Discover how marine resources are becoming India's next big wellness breakthrough in 2026.
While the world chases synthetic supplements, Indian scientists have been quietly unlocking the health secrets hidden in our oceans. The ICAR-Central Marine Fisheries Research Institute (CMFRI) has developed a revolutionary nutraceutical from select seaweeds designed to boost innate immunity—including protection against post-COVID complications .
The Science Behind Seaweed
This 100 percent natural product combines highly nutritious bioactive ingredients extracted using eco-friendly green technology. Dr Kajal Chakraborty, who led the research at CMFRI's Marine Biotechnology Division, explains that bioactive pharmacophore leads from seaweeds form the foundation of this breakthrough .
Preclinical trials have shown promising results. The nutraceutical demonstrated antiviral properties against the delta variant of SARS-CoV-2, with a significant reduction in viral infection rates observed in treated cells .
How It Works
The Cadalmin™ extract elevates innate immune responses by regulating the secretion of pro-inflammatory cytokines and chemokines. It interacts with membrane-associated pattern recognition receptors, potentially preventing virus entry through cellular signaling pathways while stimulating beneficial inflammatory cytokine production .
For those concerned about side effects, the news is reassuring. Detailed preclinical trials established no toxicity concerning clinical and behavioural symptoms. The product offers a naturally derived alternative for managing inflammation and autoimmune disorders .
A Decade of Marine Innovation
This marks the tenth product in CMFRI's series of nutraceuticals derived from marine organisms. The institute has previously developed solutions targeting type-2 diabetes, arthritis, cholesterol management, hypertension, hypothyroidism, osteoporosis and fatty liver .
Each product harnesses the unique properties of marine biodiversity, offering natural alternatives for India's growing lifestyle disease burden. The active ingredients are packed in plant-based capsules, with large-scale extraction optimised in factory units demonstrating commercial feasibility .
The Future of Marine Wellness
With commercialisation processes underway, these seaweed supplements could soon reach Indian households. For a population grappling with rising autoimmune disorders and chronic inflammation, marine-based solutions offer hope rooted in rigorous science .
