Vitamin D levels in Australians
Intersting survey especially if you live in the southern states. You may need to supplement in the winter time.
Victorians take note!!
“In the 2011-12 Australian Health Survey 23% of Australian adults were vitamin D deficient (<50nmol/L). This included 17% who were mildly deficient (30-49 nmol/L), 6% who were moderately deficient (13-29 nmol/L) and less than 1% who were severely deficient (<13nmol/L).[18] Vitamin D levels varied considerably by season with deficiency less common in summer (14%) than in winter (36%).
While there was little variation between the states and territories in summer, in winter vitamin D deficiency was more common in Victoria (49%), ACT (49%) and Tasmania (43%), but remained low in Queensland (15%) and the Northern Territory (17%). Vitamin D deficiency was more common among those living in major cities (27%) compared with those living in regional (16%) and remote areas (9%)[18].”
