Vitamin D replacement in children, adolescents and pregnant women in the Middle East and North Africa

In children, adolescents and pregnant women from the MENA, an intermediate vitamin D dose of 1000-2000 IU daily may be necessary to allow for the majority of the population to reach a desirable 25(OH)D level of 20 ng/ml. Further high quality RCTs are required to confirm/refute the beneficial impact of vitamin D supplementation on various clinically important outcomes.
