No scientific evidence exists that dietary supplements such as vitamins can help manage or prevent Type 2 diabetes, reports the National Center for Complementary and Integrative Health. Diabetics should only take vitamin supplements if they are pregnant, elderly, vegetarian, on a low calorie diet or vitamin deficient for some other reason, adds WebMD. People with diabetes should try to obtain needed vitamins and minerals from their regular diets, advises the American Diabetic Association.
The best ways to manage Type 2 diabetes are a healthy diet, exercise and regular blood glucose tests, according to the National Center for Complementary and Integrative Health. Taking certain dietary supplements may cause kidney problems or negatively affect diabetes treatment. Health care providers can help diabetics develop meal plans that stipulate when, how much and what to eat to meet their nutritional needs and control their blood sugar levels, points out the National Institute of Diabetes and Digestive and Kidney Diseases.
Although diabetics may not consider vitamin supplements to be drugs, they should inform their health care providers if they are taking them and enter them on their written records as medications, states the American Diabetic Association. They should ask about any possible side effects or how the supplements may interact with their existing medical conditions.
