Last July I went to the doctor because I was tired so often. The doctors ran a few tests and they came back that my vitamin D and vitamin B levels were pretty low. The doctor told me to take supplements over the counter. I've been doing that for the past 6 months. I went to have the levels retested and believe it or not my vitamin D level was DOWN (even after taking a supplement) Now I am high risk for osteoporosis. I have doubled my vitamin D dose and will be retested in 3 months.
More will be revealed.
