November Is American Diabetes Month
There are 23.6 million adults and children in the United States living with diabetes. Conventional medical treatments are available to control diabetes and its complications. However, some people also try complementary and alternative medicine (CAM) therapies, including dietary supplements. An individual considering using CAM therapy, should talk to their health care providers to ensure safe and coordinated care.
What is Diabetes?
Diabetes is a disease in which the body does not produce or properly use insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles.

More Resources
Researchers in the Diabetes Unit of NCCAM's Division of Intramural Research are studying many aspects of diabetes, including what happens when the body does not properly react to insulin. Current studies involve nutritional supplements and functional foods. Clinical protocols include evaluating effects of vitamin C, glucosamine, and dark chocolate to alter insulin resistance and endothelial dysfunction in a variety of important diseases including diabetes, obesity, and hypertension. Future laboratory and clinical studies may include investigations of magnesium, green tea, alpha-lipoic acid, and other nutritional supplements, nutraceuticals, botanicals, and functional foods.
