I can tell a significant difference in how I don’t catch stuff since I have been tested and brought the levels up in my blood stream. You mentioned osteo, I had my bone density testing done last year and my bones are equivalent of a woman about half my age, as a non-drinker, non-smoker and I don’t drink carbonated drinks (high in phosphorus as you probably know) it seems I am doing something right with my supplement regimen.
