Astaxanthin is known as "the king of carotenoids", a natural wonder and one of nature's most powerful antioxidants, known to provide a wide range of health benefits. As a leading astaxanthin producer, our natural AstaPure® astaxanthin is derived from a microalga called Haematococcus pluvialis. During the summer, when ponds begin to dry up, the microalga produces astaxanthin to protect itself from stressful environmental conditions. Astaxanthin enables the microalga to preserve its DNA undamaged, ready to grow again when the next rainfall arrives, even if this takes many years. This extraordinary ability demonstrates astaxanthin's role as an exceptional antioxidant. In fact, studies have shown that natural astaxanthin derived from the microalga is more than 500 times more powerful than vitamin E and much more powerful than other carotenoids. Astaxanthin, a deep, intense red pigment, is known not only to give shrimp, krill and salmon their distinctive colours, but also to help salmon maintain the energy needed to swim upstream for more than 3,200 km, as well as enhancing birds' remarkable eyesight.
