Overview
Nutrex Hawaii's BioAstin softgels deliver 12mg of astaxanthin per serving, an antioxidant carotenoid grown from microalgae cultivated in Kona, Hawaii. The 90-softgel bottle is positioned for skin and immune antioxidant support rather than a general multivitamin role.
Astaxanthin is one of the more potent carotenoid antioxidants studied, and 12mg is a higher-potency dose than many drugstore astaxanthin products that top out near 4mg. Nutrex grows its own algae rather than sourcing it from a third party, a quality point the brand markets though the listing does not include independent testing results. It is non-GMO and gluten free.

Who it's for
Suited to people already familiar with astaxanthin who want a higher-dose softgel from a named-source grower. Not the right pick for someone looking for a general daily multivitamin or unfamiliar with what astaxanthin does.
Strengths and trade-offs
Drawn from this product's published specifications.
- 12mg high potency dose per softgel
- Grown from Kona, Hawaii microalgae
- Non-GMO and gluten free
- Single-ingredient antioxidant only
- No multivitamin coverage
Performance notes
Softgels carry the astaxanthin in an oil base, which suits this fat-soluble carotenoid since it needs dietary fat for absorption. At 12mg per softgel, one softgel a day covers what many studies use as a daily astaxanthin dose.
