Life Extension Suggestions

Any program aimed at reducing the risk of vascular disease begins with comprehensive blood testing. This step is vital to designing a program that targets an individual’s specific risk factors. Healthy adults should have their blood tested at least once a year. People who have vascular disease or a family history of vascular disease should have their blood tested twice a year to monitor their progress. The following table summarizes optimal ranges for various blood levels:
