Astaxanthin crosses the blood-eye barrier, supporting vascular health within the eyeand protecting the eyes' sensitive cells. Benefits of Astaxanthin are limited by its low absorption, as low as 50%.But Astaxanthin with Phospholipids combines 4 mg of natural astaxanthin with 80 mg of a proprietary blend of four phospholipids to facilitate maximum absorption of astaxanthin into the bloodstream, where it's transported to cells throughout the body.
