BioAstin® Hawaiian Astaxanthin®

Astaxanthin (pronounced “asta – zan – thin”) is a red carotenoid and exceptionally powerful antioxidant found in certain species of plants, animals and microalgae. Grown on the pristine Kailua-Kona Coast of Hawaii, Cyanotech sources astaxanthin from natural microalgae Haematococcus pluvialis, nature’s richest and most concentrated source of astaxanthin.

Carved out of lava fields, and fed by bright natural Hawaiian sunlight, clean crisp air, and lava-filtered Hawaiian aquifer water—this healthy environment supports a healthy farm. And for over 24 years, we have been growing it naturally, free from GMOs. Because it matters where it’s grown.
