Insulin plays an important
role in the body

The role of insulin in the body is to help move blood sugar from your blood stream into your cells. This gives your cells energy. Everyone’s body needs insulin. But when you have diabetes, your body doesn’t make any or enough insulin and/or your body does not properly use the insulin it makes.

Insulin is an essential part of treatment for people whose bodies cannot produce insulin on their own or are not producing enough.

In fact, insulin is the most effective way to control blood sugar. It’s proven to give people a greater percentage point decrease in A1C than any other diabetes medication alone.
