    With meals

    Astaxanthin is a naturally occurring carotenoid pigment responsible for the red-pink color of salmon, shrimp, and krill. Produced primarily by the microalga Haematococcus pluvialis, it is regarded as one of the most potent fat-soluble antioxidants found in nature. It has attracted research interest for its potential benefits in skin protection, cardiovascular health, and aging.
