Double Wood's AstaReal Astaxanthin is a natural and patented form of Astaxanthin that is extracted from the Haematococcus pulvialis algae. It is backed by over 150 studies, 70 of which are human clinical trials. The Algae is grown in the Unites States, in a state of the art manufacturing facility in Moses Lake, Washington. Clinical studies show AstaReal may support skin health, healthy aging, immune health, eye health, gut health, and help one recover more quickly from exercise. Double Wood offers a max 12mg dose and 60 capsules which is enough to last for a full two months. Our AstaReal is grown, harvested, manufactured, and tested right here in the USA from globally sourced ingredients.
