                                According to the Australian Bureau of Statistics, one in four Australians over 18 years old suffers from a vitamin D deficiency, a statistic that seems paradoxical given the country's sunny climate. This widespread issue, particularly noticeable during the winter months, is influenced by a complex mix of health guidelines, lifestyle factors, and environmental conditions that collectively explain why so many Australians have low vitamin D.
