WHY BRENZAVVY®

Your kidneys reabsorb glucose. Brenzavvy® can reduce that reabsorption.

HOW BRENZAVVY® WORKS

Kidney support.

Glucose control.

Brenzavvy® works on one mechanism in your kidneys with two potential benefits: less glucose reabsorption and steadier blood sugar.

Blocks SGLT2

SGLT2 is a kidney protein that recycles roughly 90% of filtered glucose back into your blood. Brenzavvy® can block it, cutting reabsorption by 30–60%.

Metabolic shift

The glucose your body flushes out carries calories with it. Over time, this can support gradual weight loss and may reduce strain on the heart and kidneys.

Glucose excreted

Once blocked, glucose leaves through your urine instead of being recycled. This can help lower blood sugar levels without requiring insulin.
