The Importance of Vitamin D

Vitamin D is required for maintenance of bone density and is essential in the functioning of the immune system. The majority of our vitamin D comes from exposure to sunlight, but unlike other vitamins, vitamin D intake from food is minimal. As such, vitamin D deficiency is common, particularly in the winter months when we spend less time outdoors.

There is a growing body of evidence supporting the positive impact of vitamin D across a wide spectrum of health issues.

Some vital functions that vitamin D perform include:

  • Strengthens the immune system
  • Benefits the nervous system
  • Strengthens the respiratory system
  • Protects against cardiovascular conditions
  • Regulates insulin secretion and blood sugar control
  • Assists with weight management
  • Assists with healthy mood wellbeing
  • Strengthens and promotes healthy bones, as vitamin D encourages calcium uptake and bone mineralisation
  • Supports good dental health
  • Assists with overall Musculoskeletal function
  • Aids proper digestion and food absorption

It can play a vital role in the prevention and treatment of chronic illnesses, such as autoimmune illness, inflammatory bowel disease, cancer, heart and artery disease, and more.

Small amounts of daily sunlight exposure can be beneficial for getting vitamin D but many people require more According to the Cancer Council Australia, sun protection to prevent skin cancer is required when the UV index is three or above (moderate or higher) in Victoria between September and April. It is not recommended to have consistent sun exposure without any form of sun protection when the UV index is three or above.

Your medical practitioner should check your vitamin D levels annually and advise on your correct doses of supplementation.

Just as the Earth is dependent on sunshine for survival, so are humans.
