1. It’s more than a vitamin

“But first, it is not just a vitamin. It actually works more like a hormone in your body, controlling over 200 genes,” Dr Sethi explains.

2. Food sources are limited

Dr Sethi points out that vitamin D-rich foods are limited. “Food sources of vitamin D are rare. You would need to eat piles of salmon, tuna, eggs, or mushrooms just to match the vitamin D your skin makes in 15 minutes of sun exposure,” he says.

3. Deficiency is usually silent

Unlike other nutrients, low vitamin D often shows no obvious symptoms for years. “It often shows up as fatigue, low mood, or frequent infections,” Dr Sethi warns.

4. Too much can backfire

“High-dose supplements can cause kidney problems. The sweet spot is 600 to 800 international units daily for most adults, but always check with your doctor first,”

5. Sunlight is the best source

Dr Sethi emphasises natural sunlight as the best way to boost your levels. “Just 10 to 30 minutes of midday sun with arms and legs exposed can generate 1,000 to 2,000 international units of vitamin D,” he says.
