Derived from *Haematococcus pluvialis* microalgae cultivated under pristine conditions, esterified astaxanthin is a stable, fat-soluble antioxidant from the carotenoid family. Astaxanthin protects the phospholipid membranes of cells from oxidative damage.1 In studies, it has demonstrated the ability to cross the blood-brain barrier and protect the retina, suggesting its potential for supporting the brain and nervous system from free radical damage.2, 3 Initial trials with astaxanthin suggest that it may support the skins natural antioxidant defenses against free radicals induced by sun exposure.3 In a human clinical evaluation, supplementation with astaxanthin provided enhanced antioxidant protection for the skin.4, 5 Research suggests that astaxanthin may support athletic performance, as well as joint function and comfort after strenuous exercise.6 Additional studies suggest astaxanthin's immune, cellular and cardiovascular support potential.7-9
