The page positions HoneyFil as a non-stimulant formula. That is a useful claim if you avoid caffeine.
None of the eight named ingredients is caffeine or a similar stimulant, so the label fits the stated list. That matters for people who are sensitive to caffeine or who want something they can take later in the day.
An extract such as Korean red ginseng is sometimes described as energizing, but that is not the same thing as a stimulant, and responses vary.
Non-stimulant describes the formula, not how you will feel. Some people notice restlessness or stomach upset with herbal ingredients, and without per-gummy amounts you cannot rule out other additives. Check the label for any other ingredients and stop use if something feels wrong. Individual results vary.
