The Claim
In both rats and humans, insulin increases microvascular blood flow in skeletal muscle via nitric oxide-dependent mechanisms, leading to an expanded surface area for nutrient exchange and enhanced glucose disposal through improved delivery of insulin and glucose to muscle cells.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Insulin helps more blood flow to muscles in rats and people by using a substance called nitric oxide, which helps sugar get into muscle cells better.
See the scientific wording
In rats and humans, insulin enhances microvascular blood flow in skeletal muscle through nitric oxide-dependent mechanisms, which increases the surface area for nutrient exchange and augments glucose disposal by improving delivery of insulin and glucose to myocytes.
What the research says
1 studyStudy: Muscle microvascular blood flow responses in insulin resistance and ageing
The study shows that insulin helps increase blood flow in small vessels of muscle, which helps glucose get into cells better—just like the claim says.
