The Claim

In healthy adult humans, acute physiological elevations of GLP-1 at a rate of 1.2 pmol/kg/min, insulin at 1 mU/kg/min, or their combination, do not alter pulse wave velocity over a 150-minute period, suggesting no effect on aortic arterial stiffness under these experimental conditions.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Giving healthy adults normal levels of certain hormones like GLP-1 and insulin — either alone or together — doesn't change how stiff their main artery is over about two and a half hours.

See the scientific wording

In healthy adults, neither GLP-1 (1.2 pmol/kg/min), insulin (1 mU/kg/min), nor their combination alters pulse wave velocity (PWV) over 150 minutes, indicating that acute physiological elevations of these hormones do not affect aortic arterial stiffness.

What the research says

1 study

  1. Study: GLP-1 and Insulin Recruit Muscle Microvasculature and Dilate Conduit Artery Individually But Not Additively in Healthy Humans

    The study looked at whether GLP-1 and insulin, alone or together, change artery stiffness in healthy people, and found they don’t — which matches the claim exactly.
