Despite the sun, vitamin D deficiency is widespread in the Gulf. Here is the protocol.
Vitamin D deficiency is one of the most common findings in clients we run blood work for in Dubai. The reasons are familiar. Time indoors during the hottest months. Modest clothing patterns. Effective sun protection. Diet not particularly rich in dietary vitamin D sources. Some genetic variants affecting vitamin D metabolism.
What deficiency does. Low vitamin D levels are linked to fatigue, mood changes, poor sleep, muscle weakness, slower recovery from training, and over the long term, bone density loss. The symptoms are vague and often dismissed as stress or ageing.
The test. We measure 25-hydroxyvitamin D as part of the baseline panel for almost every wellness protocol we run. Reference ranges vary but most laboratories consider 50 to 75 nmol/L as adequate and above 75 as optimal. Many of our clients arrive below 30, which is frank deficiency.
The protocol. For mild deficiency, oral D3 supplementation at a dose your clinician calibrates to your level is the first line. We often pair it with vitamin K2 to support the body's distribution of calcium that vitamin D mobilises. Take it with a meal containing some fat for absorption.
For moderate to severe deficiency, or for clients with documented malabsorption, a vitamin D3 IV course delivers a higher dose more rapidly. A typical protocol is two to four IVs across one to two months, followed by maintenance with oral supplementation and a repeat blood test at three months to confirm levels have come up.
What to avoid. Single mega-dose oral D3 (300,000 IU loads) is occasionally promoted but carries risks of acute hypercalcaemia and should only be done under direct medical supervision with monitoring.
This is not a fashionable wellness add-on. It is straightforward clinical replacement for a common, measurable deficiency. The blood test should drive the protocol. Treating without testing risks overdoing it, treating with vague symptoms but normal levels misses the real cause.
