Short answer: regular exercise, maintaining a healthy body composition, adequate sleep, and a fiber-rich diet have the strongest research support for insulin sensitivity — more than any single supplement.
What insulin sensitivity means
Insulin sensitivity describes how effectively your cells respond to insulin, the hormone that moves glucose from blood into cells. Higher sensitivity generally means better glucose management with less insulin required.
Exercise: the strongest lever
Both aerobic exercise and resistance training are associated with improved insulin sensitivity, partly because muscle contraction itself helps move glucose into cells independent of insulin.
Body composition
Excess visceral fat is associated with reduced insulin sensitivity. Modest, sustainable changes in body composition through diet and activity are linked to measurable improvements in research.
Sleep and stress
Both poor sleep and chronic stress are independently linked to reduced insulin sensitivity, likely through their effects on cortisol and other hormones.
Dietary fiber
Higher fiber intake is associated with improved insulin sensitivity, potentially through its effects on gut bacteria and slower glucose absorption.
