Astaxanthin

Astaxanthin is a natural pigment in the carotenoid family that gives salmon, shrimp, and some algae their pinkish-red color. It also acts as a strong antioxidant, which means it helps neutralize unstable molecules called free radicals that can harm cells. Because it integrates well into cell membranes, astaxanthin can protect fats and proteins inside cells from oxidative damage more effectively than some other antioxidants. People study it for possible benefits to eye health, skin protection, inflammation control, and cardiovascular function. It can reach tissues such as the retina and brain, which is one reason researchers are interested in its potential effects on vision and blood flow to the eye. Small studies suggest astaxanthin may improve visual endurance, reduce eye strain, and support healthier blood flow, but larger clinical trials are still needed to confirm these results. It is available as a dietary supplement, often derived from microalgae, and is generally well tolerated at common doses. Like any supplement, it can interact with medications or medical conditions, so checking with a healthcare provider before starting it is wise. Quality varies between products, so choosing supplements from reputable manufacturers can help ensure potency and safety. While not a cure-all, astaxanthin is a promising, naturally occurring compound that may help protect cells from oxidative stress and support overall tissue health.
