6 Supplements You Shouldn’t Take for Better Heart Health

Heart disease remains a leading health concern for many Americans, prompting a desire to proactively safeguard cardiovascular well-being. While dietary supplements are often perceived as a convenient way to boost heart health, certain formulations can paradoxically do more harm than good. Experts now caution that high doses of nutrients found in supplement form can be detrimental, even when those same nutrients are beneficial when obtained through a balanced diet.

The Risks of Supplementation

Individuals with pre-existing heart conditions or those at elevated risk of cardiovascular disease should exercise particular caution when considering supplements. Nutrition experts have identified several specific supplements that may pose risks to heart health. Understanding these potential dangers is crucial for making informed decisions about your health regimen.

Vitamin E: A Double-Edged Sword

Vitamin E, known for its antioxidant properties, is generally considered beneficial. However, Bess Berger, RDN, notes that research indicates high doses may increase the risk of heart failure and hemorrhagic stroke. Violeta Morris, M.S., RDN, specifies that an increased risk of hemorrhagic stroke was observed with doses of 111 and 200 IU per day. The U.S. Preventive Services Task Force advises against using vitamin E to prevent cardiovascular disease.

Calcium: More Isn’t Always Better

While essential for bone health, calcium supplementation may increase the risk of heart disease in healthy postmenopausal women, according to Morris. An analysis of 13 randomized controlled trials revealed a 15% increased risk of cardiovascular disease with calcium supplements in this population. Berger adds that calcium may contribute to arterial calcification, further elevating heart disease risk. However, calcium supplements can be beneficial for preventing osteoporosis, particularly for those with dietary deficiencies.

Energy and Weight-Loss Supplements: Hidden Dangers

Many energy and weight-loss supplements contain stimulants like caffeine or ephedra-like compounds. While moderate caffeine intake from sources like coffee and tea may offer some heart health benefits, Berger cautions that caffeine-containing supplements can be problematic. These supplements may strain the cardiovascular system, raise blood pressure and heart rate, and potentially increase heart disease risk.

Beta Carotene: A Risk for Smokers

Beta carotene, found in colorful fruits and vegetables, is generally a healthy addition to the diet. However, supplementation can be problematic, particularly for smokers. Studies have linked daily doses of 20-30 milligrams of beta carotene to an increased risk of death from cardiovascular disease among smokers. Morris explains that this potential harm may stem from interactions with compounds in tobacco smoke.

Licorice: Beyond the Candy

Licorice root supplements, often promoted for digestive health and other ailments, may pose risks to heart health. Michelle Routhenstein, M.S., RD, CDCES, CDN, warns that licorice contains glycyrrhizin, an enzyme that can cause sodium retention and lead to high blood pressure. This is particularly dangerous for individuals already managing hypertension.

Red Yeast Rice: A Risky Alternative

Red yeast rice, marketed as a cholesterol-lowering supplement, carries significant risks. Routhenstein explains that its active ingredient, monacolin K, is associated with muscle, kidney, and liver damage. Manufacturers often fail to disclose the amount of monacolin K present, and some illegally add the drug lovastatin.

Prioritizing Heart Health Naturally

Fortunately, several expert-approved strategies can promote heart health without relying on supplements. These include regular physical activity, stress management, prioritizing adequate sleep, and adopting a heart-healthy diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
