BioAstin Hawaiian Astaxanthin is derived from natural Haematococcus pluvialis microalgae, grown in Hawaii, under the intense Hawaiian sun, the way Mother Nature intended. Astaxanthin is a red carotenoid and an exceptionally powerful antioxidant that can give you results you can feel. Astaxanthin is best absorbed when taken with food that contains fat (e.g. nuts, avocado, coconut oil, etc.) • Nutrex Hawaii, founded in 1999, is the leading producer of natural microalgae supplements from Hawaii.
