The dietary supplements that we take might not be proving beneficial to our heart, instead prove harmful, according to a new study. The new study was published on Monday in the Annals of Internal Medicine. A group of researchers at West Virginia University worked on the study. The research is still at an early phase and lacks proper support through evidence.
The team examined the effect of dietary supplements on the human body. The researchers examined medical records of over one million patients by analyzing 277 previous studies related to the matter. Dr. Safi Khan, a co-author of the study, said that “The majority of supplements do not affect improving survival or reducing the risk of heart attack or stroke.” Khan is an assistant clinical professor of internal medicine at West Virginia University.
The researchers called these supplements a waste of money as they didn’t provide any benefit to the heart. Supplements like multivitamins, antioxidants, iron or vitamins A and B don’t help the heart in any way, said the research. There were, however, some exceptions that might be beneficial for the heart. Fish oil and folic acid have shown signs of improving the cardiovascular health of users. There are, however, ones that possess a serious threat to heart condition calcium plus vitamin D is an example.
According to a news published by the NBC, the total sale of these dietary supplements in the United States this year will amount to $32 billion. Around 75% of US citizens take nutritional supplements of at least one kind. Doctors and researchers, however, still recommend replacing these supplements with actual food that are rich in nutrients. “You can’t just eat a crummy diet and then pop a pill and assume that’s going to solve all the problems,” said Dr. Alice Lichtenstein, director of the Cardiovascular Nutrition Laboratory at Tufts University.
