I personally have no such experience. But I live in the Far East region of Kamchatka, so I eat a lot of red salmon fish and seafood. This helps protect the body.

Astaxanthin is known as the “king of carotenoids,” being the strongest antioxidant found naturally. It means that astaxanthin is the most effective supplement if you’re into carotenoids. The astaxanthin supplement differs from many other options that can be found in everyday foods and don’t boost your health. So, let’s review what makes astaxanthin so special, and how to incorporate it into your diet.

Firstly, astaxanthin makes your skin tighter, decreasing the number of wrinkles or at least making them much less noticeable. It will result in you looking younger than your actual age. Astaxanthin allows this effect because it is able to block out skin-degrading UV rays from the sun very efficiently.

Secondly, a systematical and thoughtful intake of astaxanthin leads to eyesight improvements. In collaboration with other antioxidants, zeaxanthin and lutein, it can lower the amount of glare and blurriness. 

As astaxanthin is great at blocking out UV rays, it slows down the eventual degradation of your eye nerves. You might even have to put off buying glasses by years (and, hopefully, decades), if you start taking the supplement as a young adult.

Thirdly, it boosts the function of the heart, minimizing the effects of cholesterol and preventing deadly heart diseases. Most importantly, astaxanthin mitigates the results of our body interacting with air, meaning the oxidation of cells. Unfortunately, even air is, in some way, detrimental to our bodies.
