Still little known, the carotene astaxanthin is 54 times more powerful as an antioxidant than its more famous cousin, beta-carotene. Metabolic syndrome is the dangerous combination of 3 or more of high blood pressure, cholesterol problems, obesity and high blood sugar. It increases the risk of diabetes, cardiovascular disease and sudden cardiac death.
