The Claim

In healthy adult humans, hyperinsulinemia induced via euglycemic clamp is associated with increased nitric oxide-dependent leg blood flow, with approximately 40% of insulin-mediated vasodilation attributable to nitric oxide, compared to 20% during saline infusion, indicating enhanced endothelial nitric oxide activity during insulin stimulation.

Source: Insulin-mediated skeletal muscle vasodilation is nitric oxide dependent. A novel action of insulin to increase nitric oxide release.

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.

How it works
1 study reviewed
In plain English

When insulin levels go up in healthy adults, it helps blood flow better in the legs by turning on a molecule called nitric oxide — and it works about twice as well as when insulin isn’t active.

In healthy adult humans, hyperinsulinemia induced by a euglycemic clamp is associated with increased nitric oxide-dependent leg blood flow, with approximately 40% of insulin-mediated vasodilation attributable to nitric oxide, compared to 20% under saline infusion, indicating a significant enhancement of endothelial nitric oxide activity during insulin stimulation.

What the research says

1 study
  1. Study: Insulin-mediated skeletal muscle vasodilation is nitric oxide dependent. A novel action of insulin to increase nitric oxide release.

    The study shows that when insulin levels go up in healthy people, blood flow in the legs increases and about 40% of that effect is due to more nitric oxide being made—just like the claim says.
