(HealthDay News) — The U.S. Preventive Services Task Force (USPSTF) has found that the evidence is insufficient to evaluate the benefits and harms of multivitamins and most single- or paired-nutrient supplements for the prevention of cardiovascular disease and cancer. The Task Force findings have been published in a final recommendation statement available online February 25 in the Annals of Internal Medicine.
Researchers from the USPSTF conduced a systematic review of the current evidence on the efficacy of multivitamin or mineral supplement use to prevent cardiovascular disease and cancer in the general adult population.
The researchers note that the current evidence is insufficient to weigh the balance of benefits and harms of multivitamin use for cardiovascular disease or cancer prevention (I statement). The evidence is also insufficient to evaluate the benefits and harms of single- or paired-nutrient supplements for cardiovascular disease or cancer prevention (I statement), with the exception of beta-carotene and vitamin E, which the USPSTF recommends against (D recommendation). The recommendations apply to healthy adults, typically aged ≥50 years, without special nutritional needs.
“The USPSTF concludes that the evidence is insufficient to determine the balance of benefits and harms of supplementation with multivitamins for the prevention of cardiovascular disease or cancer,” the authors write.
