Hi Grizz, thanks for that. I am quite interested in the Vit D testimonial. I know you are a big advocate of Vitamin D and I do go through stages of taking it, but perhaps not enough. I have never had my levels tested. Did you go through testing? Do you take 10,000iu daily all the time? What brand do you take if you don't mind me asking? I am deficient in magnesium, although I supplement daily it never seems to be enough, will this be a problem?
