The Claim

In adults with type 1 diabetes, administration of insulin glargine U300 at a clinical dose of 0.35 U/kg suppresses glucagon levels more effectively than insulin glargine U100 at 0.28 U/kg over a 24-hour period, resulting in a higher prehepatic insulin-to-glucagon molar ratio of 1.78 (90% CI 1.5–2.1), which reduces hepatic glucose production and ketone formation without altering overall glucose control.

How it works
1 study reviewed
In plain English

In adults with type 1 diabetes, a higher concentration of insulin glargine U300 reduces glucagon levels more than a lower concentration of insulin glargine U100 over 24 hours, leading to a higher insulin-to-glucagon ratio that lowers liver glucose output and ketone production without changing overall blood sugar levels.

See the scientific wording

In adults with type 1 diabetes, a clinical dose of insulin glargine U300 (0.35 U/kg) suppresses glucagon levels more effectively than insulin glargine U100 (0.28 U/kg) over 24 hours, resulting in a higher prehepatic insulin-to-glucagon molar ratio (1.78, 90% CI 1.5–2.1), which may reduce hepatic glucose production and ketone formation without altering overall glucose control.

Why this might work

A longer-lasting form of insulin keeps blood insulin levels steady for more hours, which tells the pancreas to release less glucagon. With less glucagon and more insulin, the liver stops breaking down stored sugar and fat into energy, and instead stores energy. This stops the liver from making ketones, which are produced when fat is burned for fuel.

  1. Study: Greater Suppression of Glucagon, Lipolysis, and Ketogenesis with Insulin Glargine U300 as Compared with Glargine U100 in Type 1 Diabetes Mellitus

    In people with type 1 diabetes, a stronger form of insulin (Gla-300) works better than the standard form (Gla-100) to calm down the liver’s production of ketones and glucagon, without changing blood sugar levels.
