My Acupuncturist/O.M.D. was examining me by probing my hands, arms etc., I was in pain everywhere he touched. He doses me with this in a couple ounces of water and within 15 minutes he started the same probing again- all without my painful responses! He recommended this product, and of all the vitamins, minerals and other supplements, this one does the most noticeable work for me. It helps relieve joint pain and leaves me feeling more flexible and able to physically perform daily activities. Almost every day, I have told others with similar complaints to go to Earthturns.com to read up on "MSM"! It is truly my "miracle" drug!
