How is it possible that the football player mentioned in the article can suffer from a deficiency level that's severe enough to collapse?
I would expect that regularly being outside (for practice) and a normal balanced diet would be sufficient to at least get by in a country like the UK. Some depressive/lower energy symptoms during winter time, maybe, but nothing so severe as collapsing.
Shouldn't this problem show up in a much larger portion of the population? Or do very physically active individuals require more Vitamin D?
