Ingestible routes of Fx in humans. (A) Chemical structures of fucoxanthin (Fx) and fucoxanthinol (FxOH). (B) Ingestible routes of Fx in humans. Whole brown algae, such as Undaria pinnatifida (Wakame) and Sargassum horneri (Akamoku), collected in the winter, when the content of Fx is the highest, may be beneficial for human health. Furthermore, Fx extracted from brown algae and microalgae can be added to various edible items to customize their route of ingestion by humans.
