Antioxidant Effect: Astaxanthin is among the most potent carotenoid antioxidants, protecting cells from oxidative stress and lipid peroxidation.
Skin Health: Clinical trials show improvement in skin elasticity, moisture, and reduction of UV-induced damage.
Eye Health: Supports visual acuity, reduces eye fatigue, and protects retinal cells from oxidative damage.
Cardiovascular Support: Demonstrated to reduce oxidative stress markers, lower LDL oxidation, and improve blood lipid profiles in human studies.
Exercise Recovery: Studies show decreased muscle damage markers and improved endurance in athletes.
