Diabetics cannot properly produce or use insulin, which regulates the body's level of blood glucose.  This causes numerous problems for the more than 20 million U.S. adults and children suffering from one of the disease's many forms.  In addition to hindering the body's ability to convert foods to energy, diabetes is a risk factor for development of related illness and disease, including heart disease, stroke, kidney failure, nerve damage, and amputation.  Diabetics and those at risk for diabetes can take control of the disease through lifestyles changes such as diet and exercise.  Several natural products, including dietary supplements, are available to help control the disease. Chromium is one of the best studied minerals for diabetic support and shown to control blood glucose levels.  Supplemental chromium comes in three forms - chromium picolinate, chromium chloride, and chromium nicotinate.
