Very happy with how quickly I received my order. As for EDTA as a supplement, it does so much more that chelation. The benefits from EDTA has helped my wife with neuropathy in her toes from cancer treatment, my mother with a leg aches at night. Mo son with a sciatic nerve problem and myself with an ankle pain that would develop in the evening. We all take this once a day at bed time and the relief occurred within one week. I believe this is due to the cleansing that occurs in the blood system that allows your blood cells to work properly. I highly recommend this to anyone who has joint or nerve related pain issues.
