Astaxanthin May Help Lower Heart Rate for Recreational Exercise

A lower heart rate is better for your heart because it doesn’t have to work so hard to pump blood. A recent study suggests that daily supplements of astaxanthin may lower heart rate during exercise of recreational athletes.


Participants in the study included 28 recreational runners with an average age of 42 who were given either 12 mg of astaxanthin or a placebo daily for eight weeks. All of them performed a maximal running test on a treadmill and a maximal cycling test on a cycle ergometer before the supplementation period and at the end.


At the conclusion of the study, the researchers noted a 10% reduction in heart rate at submaximal running intensities. They did not note any difference between the two groups when they were at higher speeds, however.


Researchers from EQQIL led the study. It was published in the May 2017 issue of Medicine & Science in Sports & Exercise.


Astaxanthin has been shown to improve eye, skin and joint health and boost cognitive function. If you’re looking to increase your dietary intake of astaxanthin, consider consuming more salmon, rainbow trout, krill, and red-pigmented vegetables and fruits.
