Supplements are often touted as quick fixes for boosting energy, improving health, and even enhancing beauty. However, while these over-the-counter remedies may promise various benefits, some come with hidden dangers. Experts warn that certain supplements, even those commonly found in grocery stores or health shops, could trigger serious health problems like deadly heart attacks and liver failure.
Many people trust these everyday supplements to be safe, but taking them without full awareness of their risks can lead to unintended, potentially fatal consequences. As our reliance on quick fixes grows, so does the number of cases where people suffer from serious side effects.
Here are five supplements that doctors warn could cause severe damage to your heart and liver.
Vitamin A

While vitamin A is essential for eye health, immune function, and skin maintenance, excessive intake can cause severe health problems. Taking too much vitamin A, particularly in supplement form, has been linked to liver toxicity and heart damage.
Experts advise that vitamin A should be taken with caution, especially in the form of supplements. It is far safer to get vitamin A from food sources, such as leafy greens, carrots, and sweet potatoes.
Iron Supplements
Iron supplements are commonly used by individuals with anemia or low iron levels. However, excessive iron intake can cause serious harm to the body, including heart failure and liver damage. An overdose of iron can be fatal, with symptoms like stomach pain, vomiting, and organ failure being key indicators of iron toxicity.
When taken in excess, iron overload can cause the body to store too much iron in vital organs, leading to liver damage and even heart failure. Doctors suggest getting iron through food sources like spinach, red meat, and beans rather than relying on supplements unless prescribed by a healthcare professional.
Kava Root

Kava root, often used for its calming effects and to reduce anxiety, is a popular supplement for stress relief. However, its long-term use can have deadly consequences, particularly on liver health. A report has linked kava consumption with severe liver damage, including hepatitis, cirrhosis, and liver failure.
Though it is marketed as a natural alternative to anti-anxiety medications, doctors have warned against using kava for prolonged periods. In fact, kava has been banned in several countries due to its dangerous side effects. Health experts recommend consulting a doctor before using kava and avoiding it altogether for individuals with pre-existing liver conditions.
St. John’s Wort

St. John’s Wort is often taken for its potential to alleviate depression and anxiety. However, it can interfere with numerous medications and cause liver toxicity. The Lancet study revealed that St. John’s Wort can affect the metabolism of certain drugs, making them less effective and potentially leading to adverse reactions in the liver.
While St. John’s Wort is available over-the-counter, it is not without risk. The supplement has been linked to severe liver damage when combined with certain prescription medications, such as blood thinners and anti-depressants. Medical experts strongly caution against taking this supplement without consulting a healthcare provider first.
Green tea extract

Green tea extract is commonly used for its weight loss and antioxidant benefits. However, in concentrated supplement form, it has been linked to liver damage and heart complications.
While drinking green tea is generally considered safe, the concentrated form found in supplements can be harmful in large doses. Experts warn that the powerful compounds in green tea extract can overwhelm the liver and other organs when consumed in excess. If you enjoy the benefits of green tea, it’s much safer to drink the beverage rather than relying on supplements.
Conclusion
By being aware of the potential risks associated with these supplements, you can make better-informed choices about your health. Always consult with a healthcare provider before adding new supplements to your diet, especially if you have pre-existing conditions or are taking other medications.
