The Claim
In healthy adult humans, a euglycemic insulin clamp administered at a rate of 1 mU/kg/min for 120 minutes induces a significant increase in microvascular blood volume (MBV) and microvascular blood flow (MBF) in both skeletal and cardiac muscle, indicating that physiological insulin levels acutely recruit muscle microvasculature to expand endothelial surface area available for nutrient exchange.
What the research says
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.
When healthy adults get a controlled dose of insulin for two hours, it boosts blood flow and blood volume in their heart and muscle tissues, helping more nutrients move between blood and muscles.

In healthy adults, a euglycemic insulin clamp at 1 mU/kg/min for 120 minutes causes a significant increase in skeletal and cardiac muscle microvascular blood volume (MBV) and microvascular blood flow (MBF), demonstrating that physiological insulin levels acutely recruit muscle microvasculature to enhance endothelial surface area for nutrient exchange.
What the research says
1 studyThe study shows that insulin, at normal levels, increases blood flow and volume in muscle microvessels in healthy people, which supports the idea that insulin helps deliver nutrients by opening up more blood vessels.
