NOW Foods GTF Chromium 200 mcg tablets provide chromium in its biologically active Glucose Tolerance Factor (GTF) form — the specific chromium complex your body uses to enhance insulin receptor sensitivity and support healthy blood glucose metabolism. GTF chromium works as a cofactor for insulin, amplifying its ability to transport glucose from the bloodstream into cells for energy. Research supports chromium supplementation for improving insulin sensitivity, reducing fasting glucose and HbA1c, and supporting healthy carbohydrate metabolism — benefits particularly relevant for those with insulin resistance, metabolic syndrome, or type 2 diabetes. NOW Foods delivers 200 mcg per tablet — the dose used in clinical studies — in a convenient tablet format manufactured in their GMP-certified facility with potency verification on every batch.
