Another good read and am following it’s guidelines. I’m not taking a massive dose of vitamin D yet but I have been taking 5-10000iu a day for over a year now and haven’t succumbed to any illness that has swept through the office. I used to get colds a fair bit and always picked up whatever was going round so I’m convinced that vitamin D is the key. I added K2 about 3 weeks ago when I read the book but I haven’t noticed any difference yet.
