DOES IT WORK?
Fructose is a simple sugar found naturally in fruit but used in supplements purely as a sweetener. At the small amounts in most supplements (1-3g per serving), it's not a health concern. But it's not adding anything beneficial either. High fructose intake from all dietary sources is linked to fatty liver, insulin resistance, and metabolic issues. The amounts in supplements are trivial, but it's still just sugar.
