Is Insulin useful for Blutzucker?

Insulin is a crucial hormone for regulating blood sugar levels. In individuals with type 1 diabetes or advanced type 2 diabetes, insulin therapy effectively lowers blood glucose and prevents complications. However, its use requires medical supervision because incorrect dosing can cause hypoglycemia. The evidence for insulin's efficacy in diabetes is human-strong (numerous RCTs and long-term studies). The provided context does not contain specific information about insulin as a medication; it focuses on DNA tests and supplements. Therefore, this answer is general. Caveat: Insulin is a prescription drug and should never be used without a doctor's guidance.
