Powerful carotenoid antioxidant, supports skin, eye, and joint health
We rank Astaxanthin by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Astaxanthin is a powerful carotenoid, which is a type of natural pigment found in certain algae and marine life. It acts as an antioxidant, meaning it helps protect the cells in your body from damage caused by unstable molecules called free radicals.
This ingredient is primarily used to support the health of the skin, eyes, and joints. Because of its strong antioxidant properties, it is often taken to reduce inflammation and protect tissues from oxidative stress.
To create the supplement, companies grow a specific type of microalgae in large industrial tanks. Once the algae have produced the pigment, the cells are broken open and the astaxanthin is extracted using solvents. This extract is then purified and dried into a powder, which is then put into capsules or softgels.
Astaxanthin is generally a mid-range expense. This is because the process of cultivating the specific algae and extracting the pure pigment is more complex and costly than producing basic vitamins.
