Vitamin D deficiency persists even during summer months

Despite its nickname as the ‘sun vitamin,’ many people experience Vitamin D deficiency even during summer months. Experts note that approximately 60 percent of the global population does not consume sufficient levels of this nutrient. While deficiency can be asymptomatic, it may manifest as muscle weakness, bone pain, or mood changes.

Several factors contribute to low levels. Dietary intake from sources like fatty fish, egg yolks, and beef liver is often insufficient for standard requirements. Environmental and lifestyle factors also play a role, including spending excessive time indoors, air pollution, and cloud cover. The timing of sun exposure is critical; sunlight at early morning or late afternoon may not provide the necessary UVB rays for production due to the angle of the sun.

Biological factors such as aging, darker skin tones (due to melanin absorbing UV rays), and the use of sunscreen can also reduce production. Additionally, certain medical conditions involving the liver, kidneys, or intestines, as well as specific medications, can impact levels. Medical professionals advise against self-supplementation, as excessive intake can lead to high calcium levels and kidney issues, recommending consultation with a doctor instead.
