Furthermore, vitamin D is crucial for immunity and a healthy immune system as it encourages the production of natural antibiotics and anti-viral agents within the body. As the ?sunshine vitamin?, it is thought that the seasonal flux of common colds and flu throughout the winter months.

Emerging research also suggests that vitamin D can play a key role in the prevention of cancer and can potentially help with cancer treatment.
