Insulin not only moves glucose into the cells, but it also escorts Vitamin C. Blood sugar hogs the seats on the bus in most diabetics, therefore reducing the amount of Vitamin C we can absorb. This is the premise of The GAA Theory: high glucose levels hinder vitamin C entry into cells.
Vitamin C is vitally important for many functions throughout the body - a big one being metabolism. Glucose and Vitamin C are similar in the way they enter the cells. Both molecules require help from insulin. The name for the process that brings glucose and Vitamin C through cell membranes is insulin-mediated uptake. The insulin-mediated uptake of glucose and vitamin C uses white blood cells. White blood cells have more insulin pumps and they may contain 20 times the amount of vitamin C as ordinary cells.
So does increasing your Vitamin C help boost your glycemic control? Diabetes Health cited a study that confirms daily doses of 2,000 mg of absorbic acid improved both fasting blood glucose and HbA1c readings in patients with type 2 diabetes. Next time you swing by the store - see if some Emergen-C can help you achieve better glycemic control. With 1,000 mg of Vitamin C per packet - their homepage says: Feel The Good. Little did they know how good it could be for Type 2 diabetics!
