FontActiv diaBest Improves Blood Glucose Levels

Slow-release carbohydrate in FontActiv diaBest provides better glycemic control as they are digested slower, providing a gradual glucose release into the bloosstream. Whey protein also aids in blood sugar regulation by stimulating the production of the hormone insulin in the pancreas.

Whey protein when combined with carbohydrates stimulate insulin release and reduces postprandial blood glucose levels in type II diabetes.
