Husband recently started taking humalog (insulin lispro). is this the best insulin ?

It's really good.: Humalog (insulin lispro) is a brand of rapid-acting Insulin produced by eli lilly & co. Here in the usa. It is given at meals (or in an Insulin pump), to provide quick-onset action to control blood sugars at meals. There are a couple of other brands of rapid-acting Insulin on the market (novolog, apidra), but they all have about the same action.
