Evaluate Your “D” Intake
To get the biggest benefit from your vitamin D supplement, you may need to increase your dose, suggests a new study published in Anticancer Research. Adults need 4,000 to 8,000 IU of vitamin D daily to reduce their risk of several diseases—breast cancer, colon cancer, multiple sclerosis and type 1 diabetes—by about half, say researchers to who studied several thousand supplement users. That’s much higher than the 600 IU recommended daily by the National Academy of Sciences Institute of Medicine but is still well within the range the committee considers safe. Increase your blood levels of vitamin D by upping your supplement dosage, spending 20 minutes in the late morning or early afternoon sun and eating more D-rich foods, such as seafood and fortified dairy.
