Vitamin D is renowned for supporting bone and muscle health, but its benefits extend further. A landmark study published in The BMJ, led by researchers at Queen Mary University of London, analyzed raw data from 25 randomized clinical trials involving nearly 11,000 participants across 14 countries. The findings show that vitamin D supplementation significantly lowers the risk of acute respiratory tract infections.
The protective effects are strongest in people with vitamin D deficiency, particularly with daily or weekly dosing rather than infrequent boluses. Researchers estimate that over three million people in the UK could prevent colds and flu through adequate intake. They advocate fortifying foods with vitamin D, alongside natural sources like oily fish and shiitake mushrooms. For those in sunny areas, safe sun exposure—always with sunscreen—remains an effective way to boost levels, as UVB rays penetrate to synthesize the vitamin.
Empower your health: prioritize vitamin D to stay resilient against respiratory bugs.
