Physiologic levels of nitric oxide (NO) enhance insulin sensitivity and glucose uptake in skeletal muscle by improving microvascular perfusion and directly blocking inhibitory interactions with insulin signaling pathways.

Maintaining healthy nitric oxide levels through exercise (which increases shear stress and NO production) supports insulin sensitivity. This happens by improving blood flow to muscles and directly enhancing the cellular signaling of insulin, helping your body manage blood sugar and energy more efficiently.

ModerateSupportsMEDIUM confidence
Higher skeletal muscle NOS expression and activity improve insulin action via NO/cGMP/cGK signaling. Insulin sensitivity is enhanced indirectly as NO increases – skeletal muscle microvascular perfusion, delivering nutrients and insulin to target tissues... – directly as NO/cGK blocks the inhibitory interaction of the small GTPase Rho/Rho kinase with insulin receptor substrate (IRS)-1.
