United States: Numerous adults habitually consume daily multivitamins with the aspiration of enhancing their well-being. However, a recent investigation casts doubt on their efficacy.

This research, unveiled in JAMA Network Open on Wednesday, scrutinized data from approximately 400,000 healthy US adults monitored over more than two decades, revealing no correlation between regular multivitamin consumption and diminished mortality risk.

Spearheaded by scholars from the National Cancer Institute of the National Institutes of Health, the study highlighted that the subjects were generally healthy, indicating the necessity for further exploration among populations with nutritional deficiencies, according to reports by CBS News.

“We observe no advantage in mitigating death from cancer, cardiovascular disease, or cerebrovascular events through multivitamin intake,” stated Dr Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, during a segment on “CBS Mornings” Thursday.

She emphasized the superiority of obtaining vitamins from whole foods such as fruits and vegetables. Yet, the potential benefits of multivitamin usage can vary based on individual circumstances.

“There are some people who are at risk for vitamin deficiencies, so people with chronic kidney disease, people who might not absorb vitamins because they’ve had bariatric surgery or because they have GI issues,” she noted.

Pregnant individuals, for instance, should consume a multivitamin with folate to avert congenital anomalies, Gounder advised.

“There are specific demographics for whom multivitamin intake is logical, but it is not universally applicable,” she added, as per CBS News.

In a communiqué to CBS News, the Council for Responsible Nutrition, an industry body for vitamins, contended that the study overlooks the broad spectrum of health benefits associated with multivitamin use.

Gounder acknowledged that the study solely focused on mortality risk, excluding other potential advantages.

“For instance, there is evidence suggesting that multivitamin intake can mitigate cognitive decline with aging, preserving memory functions. Additionally, certain vitamins can prevent macular degeneration,” she stated, adding, “Thus, the relevance of multivitamins depends on the specific health outcomes considered. Are we examining mortality risk, or are we evaluating other disease-specific outcomes? This distinction is crucial for determining the appropriateness of vitamin supplementation for particular groups.”
