The need of vitamin C for diabetes patients has been illustrated in clinical studies showing reduced levels in diabetes patients. This occurs when there is insulin deficiency. Insulin transports vitamin C into cells, decreasing capillary permeability and improving healing of wounds however, in diabetics intracellular vitamin C is depleted leading to blood vessel damage. Researchers at the Harold Hamm Oklahoma Diabetes Center studied vitamin C for diabetes patients with insulin dependence, using it in combination with insulin. Neither insulin nor vitamin C alone produced the desired result of reduced blood vessel damage that researchers found when using combination therapy.
