Astaxanthin is a naturally occurring carotenoid pigment — not an amino acid — found abundantly in marine organisms like microalgae, salmon, and krill, with Haematococcus pluvialis being the primary source for supplements. Renowned for its potent antioxidant activity, which research suggests may be significantly stronger than many other carotenoids, astaxanthin has been studied across a notably wide range of health areas. Studies indicate it may help support skin elasticity and moisture, promote eye comfort during prolonged screen use, ease exercise-induced muscle soreness, and contribute to joint flexibility, likely through its ability to modulate oxidative stress and inflammatory pathways. Emerging research has also explored its potential role in supporting cognitive function, though larger human trials are still needed to fully clarify the scope of its benefits.
