Chromium

Chromium is a trace mineral essential for normal glucose and insulin metabolism, thought to enhance insulin's ability to bind to its receptors and facilitate glucose uptake into cells. Some research suggests that chromium supplementation (typically 200-1,000 mcg daily of chromium picolinate) may help improve blood sugar control, reduce insulin levels, and decrease cravings in women with PCOS, though results across studies have been mixed. As a safe, well-tolerated, and affordable supplement, chromium is often included in comprehensive PCOS supplement protocols targeting insulin sensitivity, particularly alongside more strongly evidenced interventions like inositol.
