Why I'm off for some vitamin D

Vitamin D is in the news again, and while the experts squabble over it, I'm off to buy myself some supplements. The chief medical officer for England has told GPs like me to advise those at risk to take supplements. And since half the adult population of the UK is lacking vitamin D in the winter months and deficiency is being linked to a growing list of health problems, I can't see a good reason not to take a small multivitamin a day – at least until the sun comes out. I'll stick to the recommended daily amount as you can have too much of a good thing, even vitamins.
Vitamin D is essential for bone growth and health, and deficiency can cause rickets in the young and a condition called chondromalacia in adults. You wouldn't think rickets still existed in the UK but it probably never went away and is increasingly recognised as a cause of fractures in susceptible children.
