Diabenil contains a comprehensive blend of botanicals and nutrients to support healthy blood sugar levels and help protect nerves, blood vessels, eyes, and kidneys.* Gymnema sylvestre supports already normal blood sugar levels.* Momordica charantia (bitter melon) appears to enhance glucose utilization and depress glucose synthesis in the liver.* Vaccinium myrtillus (bilberry) contains flavonoids that appear to support ocular tissue.* These flavonoids and quercetin strengthen blood vessels and help maintain healthy connective tissues.* Quercetin – in a Thorne-exclusive phytosome for optimal absorption – also inhibits the conversion of glucose to sorbitol, which can otherwise accumulate in the lens of the eye and in the kidneys and nerves.* Lipoic acid can significantly reduce lipid peroxidation of nerve tissue.* Chromium picolinate and vanadyl sulfate are included to help maintain already normal hemoglobin A1C levels.*

Gymnema sylvestre, a plant native to India, has been used medicinally for more than 2,000 years. Its effect on supporting blood glucose levels has been widely studied since the 1930s.* It can also help maintain already normal cholesterol and triglyceride levels.*

Momordica charantia (bitter melon) is a botanical commonly grown in China, India, and Africa. Its active ingredients include charantin and a substance known as p-insulin (plant insulin), which resembles bovine insulin in its structure and function.*

In supporting eye health, the anthocyanoside flavonoids in Vaccinium myrtillus (bilberry) are particularly supportive of retina health.*

Lipoic acid is a potent antioxidant in both water-soluble and fat-soluble mediums.* Like quercetin, lipoic acid has been shown to inhibit the conversion of glucose to sorbitol.*
