Its amazing to think that just over 100 years ago, humans had not discovered the crucial role insulin plays in our body. From metabolizing carbohydrates, fats and proteins, to ensuring the balance of our blood sugar levels remains constant to support our body. We have gone through an amazing process of theory, discovery, utilization and now optimization of this amazing peptide hormone that provides a new lease of life to people with Diabetes mellitus, and we should celebrate this marvel of science that resulted in a Nobel Prize in medicine for their discoverers. Join Dale and Tracy as they tell the story of the discovery of insulin, how it was first used in humans, and the types of insulin analogues we have on the market today. Each analogue has its own unique characteristics that provides patients requiring insulin the flexibility in their management of their chronic disease, and they explain why each brand of insulin is different, and why some will work for people and others wont.
