When it comes to supplements, many people assume that “natural” means “safe”—but that’s not always the case. In fact, certain over-the-counter supplements can pose serious risks to your heart health, especially if taken in high doses or combined with other stimulants. According to medical experts, some of these products can spike your blood pressure, trigger irregular heart rhythms, or even increase your risk of heart attack or stroke. Ahead, we break down three potentially dangerous supplements that doctors say you should approach with caution—especially if you have a heart condition or high blood pressure.

1. Licorice Root
Licorice root is herbal supplement that may seem harmless but can be dangerous, especially for anyone with pre-existing heart issues. "Taking too much licorice may cause problems with potassium levels, raise blood pressure, and cause heart irregularities," health expert Dr. Michael Lahey says. Better safe than sorry!
2. Yohimbe
Unfortunately, many supplements promising weight loss can be a nightmare for your heart. Yohimbe is one that has gained popularity as a fat burner and a supplement for enhancing sexual performance. However, Dr. Lahey warns against it, especially if you want to keep your heart health in good shape. "Side effects include an increase in pulse rate and blood pressure—not a plus for any person with heart problems, especially those who are more than fifty years old," he cautions. Instead of turning to Yohimbe, he recommends focusing on "lifestyle modifications to enhance cardiovascular functioning," such as a balanced diet and regular exercise.
3. Ephedra
Ephedra, once a popular supplement for weight loss, was banned by the federal government in 2000 due to its dangerous side effects. "Ephedra can produce a spike in blood pressure, and increase the risk of heart attacks or abnormal heart rhythms," Dr. Lahey warns. Although it's been banned in the United States, supplements containing ephedra might still be available on some shelves. When it comes to weight loss, your best bet is to stick to tried and true methods—like regular exercises and a healthy diet—rather than turning to supplements.
