A new study reveals that a common dietary supplement, often marketed as a natural energy booster, may actually increase the risk of heart-related health issues when consumed in high doses. Researchers found evidence suggesting that excessive intake could lead to elevated blood pressure and irregular heart rhythms, contradicting its widespread promotion as a safe alternative to stimulants. The findings highlight a growing concern over unregulated supplements, as many lack rigorous testing before reaching consumers. Health authorities are now urging caution, emphasizing the need for further investigation into long-term effects.
