Large doses of certain vitamins may also interfere with the absorption of other nutrients, reduce the effectiveness of some medications and cause false readings on lab tests. High doses of Calcium may reduce the absorption of iron. Too much vitamin E may increase the risk of bleeding in people taking blood-thinning medication. High levels of Vitamin C may produce false results in many different lab results, including blood tests and urine- glucose tests. Research suggests that taking doses above the minimum requirements can prevent or reduce the risk of some chronic diseases, including cancer and heart disease. Some scientists believe large amounts of certain antioxidant vitamins, such as vitamins A,C, and E, can prevent cell damage that may result in premature aging and degenerative, including Alzheimer 's disease, cancer, and heart disease. In 2003 a study by the U.S. Preventive Services Task Force, concluded, however, that there was little evidence to support the use of vitamin supplements to prevent cancer or heart disease.
