Following on from another thread about some countries “not” having Vit D deficiency, I thought I’d do a quick google scholar and see what I could find. Australia & New Zealand Between 11-100% greatly varied due to season, age and ethnicity Paper UK About 35% of 4-18 year olds Paper USA 21-49% of sample 6-18 year olds Paper Iran 86% of 9-12 year olds Paper India 10-35% of 10-18 year olds Paper And then they all started to blend but basically Malaysia and Singapore for kids is pretty Vit D safe.
