I take natural supplements. I have seen the benefits! I still play softball at my age of 57, I stay very active coaching and playing. I also am under the care of a Doctor of Homeopathic medicine, Chiropractor and Acupuncturist. My wife, Sharon is also an RN and we have seen the benefits of Vitamin D. Are you getting enough Vitamin D? It has many known health benefits |ow.ly/tRc4o
