Overview
Dr. Mercola's astaxanthin capsules provide 4mg of astaxanthin per serving from organic microalgae extract, packaged as 90 capsules for 90 servings. It is positioned as an antioxidant support supplement.
Astaxanthin is a carotenoid pigment extracted from microalgae, and the organic sourcing claim here refers to how the algae itself is grown rather than a synthetic version of the compound. A one capsule per day count over 90 servings gives roughly three months of use per bottle.
