| Unlike the other Chromista, Xanthophyta completely lack the brown pigment fucoxanthin. |
| However, the dinoflagellates Karenia brevis, Karenia mikimotoi, and Karlodinium micrum have acquired other pigments through endosymbiosis, including fucoxanthin. |
| Researchers noted a particular compound found in wakame, a carotenoid called fucoxanthin, probably contributed to this effect. |
| Most also contain carotenoid pigments, such as the brown pigment fucoxanthin, that give the cells a yellow, orange, or brown color. |
| An interesting, extra, metabolic benefit of fucoxanthin administration in rodents is the promotion of the synthesis of docosahexanoic acid in the liver. |
| Putative releasers or antioxidant protection may occur with fucoxanthin, beet root, spirulina, spinach, Ashwagandha, grape seed extract. |
