Insulin is a hormone produced by the pancreas to regulate the amount of sugar (glucose) in the bloodstream. For people with diabetes, the body either does not produce enough insulin (type 1 diabetes) or does not properly use the insulin it produces (type 2 diabetes). Therefore, insulin therapy is often necessary to help manage blood sugar levels and prevent complications.

Proper storage of insulin is crucial because it is a delicate substance that can lose its effectiveness if not handled correctly. Several factors can affect insulin stability, including temperature, light exposure, air exposure, and expiration dates. It is important to understand these factors and follow storage recommendations to maintain the potency of your insulin.
