A recent report from the US Preventive Services Task Force in the Annals of Internal Medicine focused on the use of vitamin, mineral, or multivitamin supplements. Their conclusions are that the current evidence is insufficient to assess the benefits and harms of these supplements with respect to prevention of cardiovascular disease and cancer. However, they did issue caution for high doses of vitamin E and beta carotene supplements.
For the most part, experts at the Linus Pauling Institute agree with these findings, as they are supported by an evidence-based review of the scientific literature on vitamin and mineral supplements.
But LPI wants to make this clear: you shouldn’t stop taking your multivitamins.
