I like the product because it has the ability to boost the health of your skin, joints, eyes, heart and brain. It is more potent that Vitamin C, E, and Beta Carotene. Its antioxidant properties help with oxidative stress and inflamation in the body. It is helping me, but it took awhile. Like all supplements, what works for one person may not work for someone else as we all have a different chemical makeup. Also, certain products do not work immediately and can sometimes take serveral weeks or months before you get the best results. If you need some additional detailed info on astaxanthin or other products, I suggest you go to the Nootropics Expert website. I use that site to research information on certain products I am considering trying. Hope this helps!
