May interact with antihypertensive medications by enhancing blood pressure lowering effects; monitor closely if on such drugs.
Limited data on safety during pregnancy or breastfeeding; avoid use in these populations and consult a healthcare provider.
No known allergens in the formulation; hypoallergenic and free from common irritants like gluten, soy, and dairy.
