Victorian Government Report

Australian government is currently spending $100 million a year in testing for vitamin D deficiency.

So what does this all mean, and how can you increase your Vit D intake?

During the summer months, just outside the peak ultraviolet radiation B times of 10am to 3pm, it is recommended all Australians go outside mid-morning or mid-afternoon for a brisk walk for six to eight minutes, exposing their arms, face and hands.

Professor Michael Holick, endocrinologist and world-renowned vitamin D specialist, suggests “All adults can supplement with at least 2000IU daily with little risk of toxicity, even with long-term supplementation. The only time to screen should be when treating those at higher risks of toxicity: those with sarcoidosis, tuberculosis, Williams syndrome, and any other diseases of vitamin D hypersensitivity.”
