The Vitamin D Study

Prevalence of Vitamin D deficiency in adults & prevention of respiratory tract infections

Vitamin D & respiratory tract infections

A large body of studies have shown Vitamin D levels to be of great importance in the prevention and severity of acute respiratory infections. Vitamin D protects against pathogens including viruses via the innate and adaptive immune system, involving white blood cells and T-cells. It is known, that a large proportion of Australians are Vitamin D deficient, specifically older people. Research has shown Vitamin D supplementation to be a key to alleviate Vitamin D deficiency.
