Latest Supplement Recommendations
New draft recommendations on vitamin and mineral supplement use were published this week by the U.S. Preventive Services Task Force. The recommendations apply only to healthy adults without nutritional deficiencies. They focus only on the use of supplements for the prevention of cardiovascular disease and cancer at doses not exceeding tolerable upper intake levels. The recommendations are based on existing science and are generally consistent with information already presented in ConsumerLab.com's Product Reviews. We have summarized the recommendations below, with links to more information in ConsumerLab.com's reports:
