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.
