Astaxanthin
herbs
Astaxanthin is a naturally occurring carotenoid pigment found in algae and seafood with potent antioxidant and anti-inflammatory properties. It crosses the blood-brain barrier and the blood-retinal barrier, making it uniquely effective for protecting neural and ocular tissues. Research suggests benefits for cardiovascular health, exercise recovery, and age-related cognitive decline.

Clinical studies demonstrate astaxanthin's superior antioxidant capacity compared to beta-carotene and vitamin E, with particular efficacy in reducing inflammation markers and supporting endothelial function. Evidence supports its use for exercise recovery, with improvements in muscle soreness and fatigue noted in multiple trials.
