Natural Astaxanthin and vision
When it comes to vision, Natural Astaxanthin is one of the most important nutrients to consider. Astaxanthin is a xanthophyll carotenoid produced by the microalga Haematococcus pluvialis. Unlike beta-carotene, it has no pro-oxidant activity at any dose. Crosses the blood-retina barrier, making it uniquely effective for eye health.
What dose to look for
Clinical studies typically use 4–12 mg of natural astaxanthin. 4 mg/day for eye health and general antioxidant support; 6–12 mg/day for cardiovascular and lipid benefits. Take with a fat-containing meal for best absorption. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
