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.
A recent systematic review and meta- analysis of 7 studies found that when adults at risk of metabolic syndrome supplement astaxanthin they significantly lower their systolic blood pressure, total cholesterol, harmful LDL cholesterol, triglycerides and, perhaps, waist circumference.
