We live in the sunburnt country so it’s perhaps ironic that up to three in 10 Aussies are deficient in the ‘sunlight vitamin’- Vitamin D.
One NSW study found that 62 percent of females were Vitamin D deficient during the spring months.[i], [ii]
Many people avoid the sun these days due to the risk of skin cancers but our body actually needs small amounts of direct sun exposure to create Vitamin D and avoid deficiency.
Vitamin D is essential for your health including healthy bones and particularly our immune function. [iii]
It may help to ward off respiratory infections associated with colds and flus and reduce the risks of allergic and autoimmune conditions.
A major international analysis found Vitamin D supplementation can help protect against respiratory infections. Researchers found daily or weekly supplementation cuts the risk of respiratory infection in half. [iv]
A variety of autoimmune conditions, including psoriasis, have been associated with Vitamin D deficiency.
If you suffer from psoriasis, studies have shown that using Vitamin D ointments is as effective as low-medium strength corticosteroid creams in managing the condition.[v]
Other autoimmune diseases associated with Vitamin D deficiency include rheumatoid arthritis, systemic lupus erythematosus and inflammatory bowel diseases.
When your skin is exposed to the sun, it produces Vitamin D and sends it to your liver for use by the rest of the body. Eating foods containing Vitamin D or using supplements can help boost daily levels.
Vitamin D benefits the muscles, cardiovascular system, the respiratory system, immune system and brain development.
Vitamin D helps us absorb other minerals like calcium and phosphorus. Even if you eat foods containing a lot of calcium and phosphorus, without enough Vitamin D, you can’t absorb them into your body.
The most natural way to get Vitamin D is by exposing your bare skin to sunlight (ultraviolet B rays).
