Broad-spectrum glucose support — Targeted nutrients and botanicals*

Three vegetarian capsules combine vitamins, minerals, alpha lipoic acid and botanical extracts to support healthy glucose metabolism, microcirculation, and pancreatic function.*

Balanced multicomponent formula

Provides vitamin C (200 mg), biotin (6 mg), magnesium (150 mg), zinc (15 mg) and chromium (400 mcg) together with alpha lipoic acid and botanical extracts.

Botanical extracts standardized for consistency

Contains cinnamon extract (Cinnamomum cassia, 10–15:1), Gymnema sylvestre (leaf, standardized to 75% gymnemic acids) and bitter melon extract (fruit, standardized to 0.5% charantin).

Vanadium in an organic complex

Includes bis-glycinato oxo vanadium (BGOV) at 7.5 mg, standardized to contain 20% vanadium for enhanced tolerability.

Vegetarian capsules and suggested dosing

Supplied in vegetarian cellulose capsules with a suggested use of three capsules daily taken in divided doses before meals.

Why It Works

GlucoFunction – This formula combines key nutrients, antioxidants and herbal extracts to promote broad spectrum support for healthy glucose metabolism

What Is It?

GlucoFunction is a combination of key nutrients, antioxidants and herbal extracts designed to promote healthy glucose uptake and metabolism, microcirculation, and pancreatic function to support healthy glucose utilization.*

Uses For GlucoFunction

Glucose Metabolism: Chromium, magnesium and zinc are key nutrients involved in glucose transport, utilization and gluconeogenesis. Optimal plasma levels are associated with healthy glucose metabolism, lipid metabolism and lean body mass. Additionally, a recent study suggests a synergistic relationship between chromium and biotin, suggesting that the combination may provide additional support. Bis-glycinato oxo vanadium is an organic complex of glycine and vanadium specially designed for enhanced absorption and tolerability. Research indicates that vanadium promotes healthy glucose metabolism, particularly supporting healthy hepatic and skeletal muscle glucose utilization. Numerous studies indicate that the water-soluble polyphenol polymers found in Cinsulin® cinnamon promote healthy glucose and lipid metabolism, in part through supporting healthy receptor activity. Momordica charantia, commonly known as bitter melon, is a traditional Indian vegetable noted for its ability to support kidney health and healthy blood glucose metabolism. Gymnema sylvestre promotes healthy glucose uptake into the intestines and supports enzyme activity for glucose utilization.*

Microcirculation: Vitamin C and alpha lipoic acid are powerful antioxidants to support red blood cell and vascular health. Additionally, vitamin C maintains healthy red blood cell sorbitol levels. Alpha lipoic acid supports nerve health and ocular health, supporting microcirculation, nerve conduction velocity and oxygenation to the retina. Furthermore, studies indicate that the water-soluble polyphenol polymers found naturally in cinnamon may support healthy blood flow.*

Pancreatic Function: Several preliminary human trials indicate that Gymnema sylvestre promotes healthy pancreatic beta cell function, in part through nutritional support of the pancreas. Additionally, alpha lipoic acid promotes healthy beta cell mitochondrial function.*
