Many people take vitamin or mineral supplements every day, hoping these supplements provide their body enough nutrients and keep them healthy.
However, a recent study from St. Michael’s Hospital gives a conclusion that may disappoint supplement users.
The researchers find that most popular vitamin and mineral supplements provide no consistent health benefit. They provide no consistent harm, too, which can be good news.
The systematic review focuses on studies published from 2012 to 2017. The supplements include vitamin D, calcium, vitamin C and multivitamins. These are the most common supplements people use.
These supplements, although are claimed to have many health benefits such as improving the immune system, reduce heart disease risk and strengthen bones, show no advantage or added risk in preventing heart disease, heart attack, stroke or premature death.
Some less common supplements, like B-vitamins with folic acid, on the other hand, may help reduce heart disease and stroke.
In addition, niacin and antioxidants have a tiny effect that may increase death risk.
The researchers feel surprised about their finding:
“We were surprised to find so few positive effects of the most common supplements that people consume.”
“Our review found that if you want to use multivitamins, vitamin D, calcium or vitamin C, it does no harm – but there is no apparent advantage either.”
They also suggest that consumers should pay attention to the supplements they use.
Using vitamin and mineral supplements to beat nutrient deficiency is okay if their healthcare providers advise them to do so.
The conclusion from that study is that to get enough nutrients for daily life, the best way is to have a healthy, balanced diet that can fulfill your vitamin and mineral needs.
“So far, no research on supplements has shown us anything better than healthy servings of less processed plant foods including vegetables, fruits, and nuts.”
The finding is published in the Journal of the American College of Cardiology.
