I and my son have issues with calcium build up. Mine were due to two collapsed discs, where calcium had protruded onto the spinal column and was causing pain and other sensations down my right leg. This had been present for 12 months and was confirmed by xray. My son's shoulder had been badly damaged many 10 years ago in a motorcycle accident and calcium deposits had begun to cause him problems as well. Both of us are now free of pain and I have no more sensations down my leg. Excellent product 5 stars!
