About this ingredient
Astaxanthin is a naturally occurring red-orange carotenoid belonging to the xanthophyll family. It is found in certain microalgae, seafood and aquatic organisms, with the microalga Haematococcus pluvialis being an important commercial source.
Astaxanthin is known for its strong antioxidant properties and has been researched for its potential role in oxidative-stress protection, eye health, skin health, cardiovascular wellness and exercise-related recovery. It is also able to interact with cell membranes because of its chemical structure.
Human research has investigated several potential applications, but evidence varies by outcome and study design. Astaxanthin is commonly used as a dietary supplement ingredient in softgels, capsules and antioxidant formulations.
