Research has shown that Chronic Kidney Disease (CKD) has been linked to Oxidative Stress. In studies on animals, results have shown that GSE may reduce kidney damage and improve function by reducing oxidative stress and inflammatory damage (19, 20, 21)

In one study, 23 people diagnosed with chronic renal failure were given 2 grams of GSE daily for 6 months and then compared with a placebo group. Urinary protein decreased by 3% and kidney filtration improved by 9%.

This means that the kidneys of those in the test group were much better able to filter urine than the kidneys of those in the placebo group (22).
