Yes, taking too many vitamins can be harmful, but saying they directly cause a heart attack is not always true. It depends on the type of vitamin, the amount, and a person’s health condition.
Some vitamins and supplements, when taken in very high doses, may create health problems. For example, too much vitamin D can raise calcium levels, and excess vitamin E or certain supplements may affect the heart or blood circulation. Overuse of supplements can also put stress on the kidneys, blood vessels, and overall heart health.
Usually, vitamins are safe when taken in the recommended amount or through a balanced diet. Problems mostly happen when people take large doses without medical advice.
