When healthy adults get a specific dose of a hormone called GLP-1 through an IV, it quickly boosts blood flow in the small vessels of their heart and muscles, helping deliver more nutrients and hormones where they're needed.

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

Randomized Controlled Trial

Human

2018 Feb 1

The study gave healthy people a specific dose of GLP-1 and found it increased blood flow and volume in muscle tissue quickly and kept it elevated, just like the claim says.

Similar Assertions

In male rats, a hormone called GIP can completely stop another hormone, GLP-1, from increasing blood flow to leg muscles—even if the rats eat junk food or regular food—and it does this without changing how much GLP-1 is in the blood.

When healthy adults get both GLP-1 and insulin at the same time, it doesn’t boost blood flow to their heart or muscles any more than using just one of the hormones alone.
