Glucocil contains mulberry leaf extract, alpha lipoic acid, banaba leaf extract, cinnamon bark powder and fish oil, according to the company website. It contains another seven ingredients intended to increase glucose uptake in the cells, reduce glucose absorption in the intestines, and support circulatory and metabolic health, among other things.
One major ingredient in Glucocil is the mulberry leaf extract, which has been used in traditional Chinese medicine dating back to 200 B.C., according to Glucosil.com. Once known as the "divine leaf," mulberry leaf was believed to have healing and anti-aging properties. This nickname persisted until at least the 16th century, when the "Compendium of Materia Medica" recommended boiling the leaves into a tea. Studies have confirmed that mulberry leaf does affect blood sugar levels, but the effect depends greatly on a number of variables, such as the time of year it is picked and where the leaves have grown.
Glucocil is recommended by the Diet Spotlight as a weight loss supplement that works by stabilizing glucose levels. It should be taken before lunch and dinner every day. While its website provides citations for various clinical studies for each ingredient, Diet Spotlight cautions that the website fails to clarify whether the studies were performed on humans or animals.
Glucocil has not been evaluated by the FDA, states Consumer Affairs. Glucocil should not be taken without consulting a doctor first, especially for diabetics.
