Astaxanthin appears to benefit the circulatory system
Astaxanthin appears to have an overall positive effect on the circulatory system. When a group of 20 men took either astaxanthin supplements or a placebo, researchers found a significant increase in peripheral capillary blood flow. In other words, blood transit time was decreased.1
One more area in which astaxanthin shows promise is maintaining healthy blood pressure. A study based on 20 healthy postmenopausal women found that an eight-week course of astaxanthin supplementation significantly reduced both systolic and diastolic blood pressure.2
Other research with a group of 127 adults showed a significant drop in systolic blood pressure after the use of 4 mg of astaxanthin daily for just a month.3
