What is Mulberry leaf Extract?

Mulberry leaf Extract, derived from the leaves of Morus alba, has been used for centuries in Traditional Chinese Medicine and is gaining modern scientific recognition for its potential health benefits. Rich in DNJ (1-deoxynojirimycin), flavonoids, and polyphenols, Mulberry leaf Extract is particularly valued for its support of healthy blood sugar levels and metabolic wellness.

Key Benefits

  • Blood Sugar Support: Contains DNJ, a natural alpha-glucosidase inhibitor that may help support healthy blood sugar levels by slowing carbohydrate absorption.

  • Metabolic Health: May help support healthy lipid metabolism and contribute to overall metabolic wellness.

  • Antioxidant Protection: Rich in flavonoids, including Quercetin and rutin, that help protect cells from oxidative stress.

  • Cardiovascular Support: May help support healthy cholesterol levels and blood vessel function.

  • Anti-inflammatory Properties: Contains bioactive compounds that may help reduce inflammation throughout the body.
