Supplements can interact with medications and health conditions. Talk with a qualified clinician, pharmacist, or registered dietitian before starting, stopping, or changing supplements — especially if you are pregnant, have a medical condition, use prescription medication, or are buying stimulant products.
Be cautious with any supplement if you use prescription medication, have kidney/liver disease, heart rhythm issues, high blood pressure, pregnancy/breastfeeding considerations, a history of disordered eating, or stimulant sensitivity. Stop and ask a qualified clinician if symptoms worsen.

We avoid disease-treatment promises and encourage clinician or registered dietitian guidance for personal medical decisions.
