I have been reading in here where some of you are feeling bad ,tired not wanting to do anything.Well let me tell you a few years ago I was like that ,I went to the Dr. and she did a blood test and I had almost no Vitamim D in my body. They say that this does not make you feel bad , But trust me it does . She put me on 5000 dose of vitamin D .I had to take one pill a week for over a month .Now I feel like a new person , She put me on Fish oil 3 times a day .calcium 3 times a day, niacin once a day and my vitamin pill . I feel good now , Us older people do not get the sun shine thet we all need and that makes our vitamin D lower than it should be . And because of my vitamin D being so low it has caused me to loose bone mass ,which means that now I have Ossiproses , Hope thats how it is spelled . Anyway get them vitamins checked .
