The UAE’s Vitamin D Gap: A Closer Look at a Region-Wide Health Priority

The UAE receives close to ten hours of sunlight a day, yet population health research consistently points to widespread vitamin D deficiency across the country. A 2025 systematic review of healthy individuals across the UAE found an average vitamin D level of just 17.63 ng/mL among adults which is well below the threshold considered sufficient with severe deficiency most pronounced among infants and children. Earlier population studies have reported figures even starker, with overall hypovitaminosis D affecting close to 97% of the people studied, and deficiency rates exceeding 83% among both men and women in Abu Dhabi.

The explanation lies less in sunlight availability and more in how people actually live. Cultural clothing norms, limited outdoor activity in a climate built around air-conditioned indoor life, and naturally higher skin pigmentation across much of the region’s population all reduce the body’s ability to synthesize vitamin D from sun exposure even in a country where sunshine is abundant almost every day of the year. Diet compounds the gap further, as few natural food sources provide enough vitamin D to offset these factors on their own.

Closing the gap demands more than a single solution. A population this varied in age, lifestyle, and physiology needs vitamin D delivered in forms built around how people actually live. For children, gentle, palatable formats like gummies and syrups support consistency without the resistance a tablet often invites. For professionals and people constantly on the move, fast-absorbing effervescents offer a format that fits into a morning routine without friction. For the fitness-driven and performance-focused, formats like energy gels combine vitamin D with the on-the-go convenience their training demands. And for women, whose vitamin D needs shift across life stages from reproductive years through menopause, targeted formulations and dosages matter as much as the nutrient itself.

This is the thinking that should guide product development in a market like the UAE: understanding not just that a deficiency exists, but that closing it at a population scale requires precision across every demographic it touches. As public health attention increasingly turns toward preventive, lifestyle-integrated nutrition strategies, the opportunity lies in meeting people with the right format, at the right dose, in the way that actually fits their life.
