Is it safe to take supplements if I have diabetes?


There are a variety of medication for the treatment of diabetes, such as biguanides (such as metformin), sulfonylureas (such as glyburide and glipizide), thiazolidinediones (such as pioglitzone and rosiglitizone) and many more. Since this is a decision that should be discussed with your doctor to see which medication would be best suited for you, it is a good idea to speak to your doctor to find out more about the available options. While supplements, such as cinnamon tablets for glucose control, may work for some people, they may not be good for everyone. It is a good idea to let your doctor know before starting any supplement to make sure it is safe for you to take.

Type 2 diabetes occurs when the body becomes resistant to insulin, a hormone produced by the pancreas that is required to produce energy. Therefore, some people turn to dietary supplements and natural substances like cinnamon and chromium to help improve the way their bodies produce or respond to insulin. Others feel there may be some benefit to taking supplements or eating foods containing alpha-lipoic acid (ALA). ALAs contain antioxidants, which are known to help prevent cell damage. Other studies are being conducted to determine whether natural substances such as garlic may help to lower blood glucose levels. However, there is no scientific evidence that any of these supplements help treat type 2 diabetes.
