Vitamin D is essential for calcium and phosphorus metabolism as well as for healthy bones. Can be found in foods such as fish, cod liver oil, eggs, enriched milk and celeals. Thus dietary intake is not enough because vitamin D is synthesized by skin exposure to sun.
Vitamin D is crucial for bone health, and also recent studies show that can increase immunity. Low serum levels of vitamin D are linked to increased cases of cold and flu in adolescents and adults, and of respiratory tract infections (bronchitis, pneumonia) in the elderly. Daily intake of 1000 IU of vitamin D reduces this incidence by 50%.
Vitamin D supports the immune system through several mechanisms:
- Increases the production of natural antimicrobial substances
- Activates T-lymphocytes
- Reduces inflammatory cytokines
Vitamin D is an essential nutrient for immune system support. D3 form is required in a minimum dosage of 1000 IU daily, during the winter.
