Very good informative presentation ... huge topic at the moment regarding dosage, I have been taking 3 x recommended level and importantly am waiting for the result of my Vitamin D blood level result ... if it is low I shall increase dosage and if too high then lower it.

Thanks very much Michael! And yes you are very correct, a huge topic indeed, given its relative abundance, huge potential benefits, and extremely low risk of side effects!
