The U.S. Preventive Services Task Force issued a recommendation statement in June 2022 on the use of over-the-counter vitamin supplements. Based on its independent panel of experts’ review of existing scientific evidence, the task force recommended against using beta carotene or vitamin E supplements for the prevention of cancer and cardiovascular disease, the two leading causes of mortality in the U.S.
The task force’s new statement is an update to its 2014 recommendation, which drew the same conclusion. In the most recent analysis, the expert panel looked at an additional six randomized control trials for beta carotene and nine for vitamin E.
