A new study reveals that a common dietary supplement, often marketed as a natural energy booster, may actually pose significant risks to heart health when consumed in high doses. Researchers found evidence suggesting that excessive intake could lead to dangerous spikes in blood pressure and irregular heart rhythms, contradicting its widespread promotion as a safe alternative to conventional stimulants. The findings raise concerns about regulatory oversight in the supplement industry, where products are not always subject to the same rigorous testing as pharmaceuticals. Health authorities are now urging consumers to approach such supplements with caution and consult medical professionals before use.
