Not too long ago my blood vitamin D level was measured at 15 ng/ml. This was considered by my GP to be perfectly adequate, and she did not recommend supplementation. Ray would consider this to be a serious deficiency, and has stated that somewhere between 50-55 ng/ml is the safe level to maintain all year round.
As far as I can tell, here in the UK anything above 20 ng/ml is considered safe.
But if Ray is right about 50 ng/ml, then this is a complete medical disaster, and millions of us are deficient.
Does anything know how Ray arrived at that specific figure of 50 ng/ml?
Does anyone know why the UK recommended levels are so much lower than this?
