What It Actually Is
Caffeine is a well-known stimulant compound, here contributed partly by the formula's Green Tea Extract and disclosed as a specific total amount.
What Research Generally Shows
Caffeine's effects on alertness and energy are well-documented, with typical single servings ranging from 40mg (tea) to 95mg+ (coffee).
On The Dose
5mg per gummy is a small fraction of a typical cup of coffee (which can run 95-200mg), positioning this as a mild energy component rather than a stimulant-driven formula.
