High blood pressure, also known as hypertension, is often referred to as a ‘silent killer’ due to its detrimental effects on the heart and arteries with minimal warning signs. In addition to factors like salt intake and stress, certain dietary supplements can exacerbate the condition. Some herbal supplements, typically perceived as safe, can actually raise blood pressure, reduce the effectiveness of hypertension medications, or strain the heart. Here are 5 dietary supplements individuals with high blood pressure should approach cautiously. Ephedra, commonly found in weight-loss and energy products, contains stimulating compounds that constrict blood vessels, leading to heightened blood pressure. Bitter orange, often marketed for weight loss, contains synephrine, a stimulant that raises blood pressure by constricting blood vessels. Licorice root, albeit seemingly harmless, contains glycyrrhizic acid which influences sodium retention, causing blood pressure spikes. Yohimbine, marketed for various purposes, increases blood pressure by stimulating the nervous system. Additionally, caffeine, prevalent in energy supplements, can further elevate blood pressure and counteract hypertension medications. It is advisable for individuals with high blood pressure to consult a healthcare professional before considering the use of such supplements.
