Loading... Please wait...MSM is a FOOD, not a medicine, drug or food additive. It is a pure white sulfur powder known as Sulfonyl Sulfur or Organic Sulfur and is found in plants, meats, dairy products and vegetation. According to Dr. Earl Mindell 'it is found in every cell of every plant and animal and is the 4th most plentiful mineral in the body.' MSM is a safe and natural, assimilable food extracted from the ocean. Dr. Stanley Jacob of the Oregon Health Sciences University discovered that DMSO when heated would crystallize and isolate 99.9 % of the beneficial component MSM. We highly recommend you get the book 'The MSM Miracle' by Dr. Earl Mindell $5.95 and learn all about the many uses of MSM and how much to take.
