Micronutrients & recovery

Vitamin D deficiency and insufficiency are highly prevalent across all demographic groups in the Middle East, driven by cultural clothing practices and limited dietary sources, despite abundant year-long sunshine.

Living in a sunny region does not guarantee adequate Vitamin D levels if your clothing covers most of your skin and your diet lacks fortified foods or supplements. You are at high risk for deficiency regardless of the weather. Consider testing your levels and discussing supplementation with a healthcare provider, as dietary sources alone are often insufficient in this region.

Despite abundant, year-long sunshine in the Middle East, vitamin D deficiency and inadequacy is prevalent due, in large part, to traditional clothing covering most of the body and the lack of foods rich in, or fortified with, vitamin D.
