Vitamin D train is chugging on

The FT has just published a comprehensive piece on vitamin D. An important point is made with respect to carrying out robust research:

"... randomised control trials are important. The trouble is, trials that could convince policymakers to advise an across-the-board increase to vitamin D recommendations for all children and adults might never take place.

There are a number of obstacles to the research, but the simplest, and biggest, is money. Vitamin D is not a proprietary compound. It’s cheap and easy to produce. A bottle of 180 1,000-IU capsules can be purchased online for about £9. No pharmaceutical company is going to put up the many millions of dollars necessary to conduct the trials."

Indeed, if there isn't any profit in it, why should private companies respond? Isn't this the moment where the government is supposed to play its hand, or are we too busy spending tax payer money scrapping roadworthy cars to subsidise the automotive industry?

Anyway, I'm happy taking my daily vitamin D supplements (1000 IU) and I'll continue to do so until the evidence tells me otherwise.
