Springtime heralds vitamin D deficiency

Vitamin D levels hit their lowest levels in early spring, not in winter as previously thought.

A study of 24,000 people in New South Wales revealed that vitamin D deficiency is also affecting more Australians, and lasting longer.

Since current testing guidelines don’t address the need to take seasonal variation into account, researchers are calling for a testing guideline review. Supplement regimes also need to be reviewed because vitamin D deficiency also plays a factor in diseases such as diabetes and cancer.
