The U.S. Preventive Services Task Force released a draft report stating that the risks of beta-carotene supplementation outweigh the benefits for prevention of cardiovascular disease (CVD) and cancer. Beta-carotene supplements have previously been linked to increased risk of lung cancer in smokers and may increase risk of dying from heart disease or stroke.
Additionally, the report found robust evidence that vitamin E supplementation is not beneficial in prevention of CVD and cancer. There is insufficient evidence to judge the risk and benefits of taking other vitamin, mineral, or multivitamin supplement for prevention of these conditions.
Getting beta-carotene from foods is safe. This vitamin A precursor is found in yellow, orange, and leafy green produce. Vitamin E is found in plant oils, nuts, and seeds. Following a healthy dietary pattern will supply the appropriate amounts of these nutrients for health.
