GLOW™ is made from whole foods that are naturally low in fructose. Furthermore, the fermentation process causes the foods to become much more digestible and tolerated. The actual sugar content of GLOW™ is tiny, at 0.98 gm per 100mgs. It is always a good idea to start GLOW™ at a reduced dose of 1/8 tsp and gradually increase until you are at the full 5g recommended dose.
