Astaxanthin is a naturally occurring carotenoid – a red plant pigment found in certain algae, yeasts, and marine animals. The richest natural source is the microalga Haematococcus pluvialis, which produces astaxanthin as a protective pigment under stress.
In nature, astaxanthin is responsible for the characteristic pink-red color of wild salmon, shrimp, and flamingos.
Astaxanthin as an Antioxidant – What the Research Shows
Astaxanthin is one of the most intensively researched carotenoids. In laboratory studies, it demonstrates an exceptionally high antioxidant capacity compared to other carotenoids and vitamins.
A special feature: Astaxanthin is both water- and fat-soluble and can therefore act in various cell areas – a property that distinguishes it from many other antioxidants.
⚠️ Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle.
