Non-stimulant is one of the badges on the page. It is a useful claim if you avoid caffeine.
None of the eight named ingredients is caffeine or an obvious stimulant, so the badge fits the stated list. The page also says it aims for energy without a stimulant crash, which is why the badge is shown.
Some botanicals, ginseng among them, are described as energizing by traditional use, and some people feel restless on herbal products. A badge cannot rule that out.
Non-stimulant describes the formula, not how you will feel. Check the label for any other ingredients and stop use if you feel unwell. If you are sensitive to stimulants or take medication, speak with a doctor or pharmacist. Individual results vary.
