I am taking calcium and magnesium gluconates for osterporosis. I am a 71-yr-old female, and have related symptoms--pain, stiffness, and don't take any meds. I have been having great success taking this supplement which I mix in lemon juice, apple cider vinegar or vit.C, add hot H2O and honey. After only a week, I no longer have pain in my wrists in yoga class. I now sleep better and can better withstand stresses w/o shaking. I plan to take the citrate forms in the future, as they are better absorbed. I also plan to resume x-country running and other activities which I've had to quit from pain. These minerals are giving me my life back.
