Nitric oxide (NO) bioavailability is significantly diminished in states of obesity and insulin resistance due to reduced NOS3 expression, impaired NOS3 activity, and increased NO quenching by reactive oxygen species.

If you have obesity or insulin resistance, your body's natural nitric oxide signaling is likely impaired, contributing to fat storage and metabolic issues. This isn't just about willpower; it's a molecular dysfunction. Strategies that support endothelial health and NO production (like exercise, which increases shear stress on blood vessels) may help restore this regulation.

NO bioavailability is decreased in animal models of obesity and diabetes [116,117] and in obese and diabetic humans [118,119].
