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.
