Other Names: Astaxanthine, Astaxantina, Dihydroxy-3,3’ dioxo-4,4’ bêta-carotène, Microalgae, Microalgue, Micro-Algue, Ovoester, 3,3'-dihydroxy-4,4'-diketo-beta-carotene, 3S,3'S-astaxanthin, 3R,3'R-astaxanthin, 3R,3'S-astaxanthin.<br>Astaxanthin is synthesized by microalgae called Haematococcus, and is also known as the "King of Carotenoids". It's grown in fresh water using sophisticated techniques that encourage the algae to grow its own powerful medicines protecting it from oxidation, UV radiation, and other environmental stressors. It is a reddish pigment that belongs to a group of chemicals called carotenoids. It occurs naturally in certain algae and causes the pink or red color in salmon, trout, lobster, shrimp, marine algae, krill oil and other seafood.
==Special Precautions of Astaxanthin==
The most commonly reported astaxanthin side effects are harmless pigment changes, such as a slightly orange tint to the skin or to stool. Even at high doses, no toxic effects have been observed, either in animals or humans. Other, less common astaxanthin side effects have a greater impact, and side effects such as low blood pressure and shifts in hormone levels can have serious health implications.
