India's Sunshine Paradox: Millions Deficient

Millions of Indians are experiencing vitamin D deficiency, a paradox given the country's ample sunshine. Endocrinologist Dr. Ravinder Goswami explains that modern lifestyles, which keep people indoors, prevent adequate vitamin D synthesis. Our skin produces vitamin D when exposed to UVB rays, with peak production occurring between 10 am and 3 pm on clear days. Glass windows block these essential rays.

Dr. Goswami's research in the late 1990s highlighted that individuals working outdoors had sufficient vitamin D levels, unlike those indoors. He notes that higher melanin in Indian skin, while protective, slows down vitamin D production, necessitating longer sun exposure for darker skin tones. While fortified foods offer some vitamin D, they cannot replace sunlight.

Caution is advised regarding supplements. Dr. Goswami warns against injectable forms unless medically necessary and advises against routine use of active vitamin D or expensive nano formulations. Standard vitamin D supplements are effective when taken under medical guidance, as excessive intake can lead to high calcium levels and kidney issues. Sensible, daily sun exposure remains the most effective and safest source.
