A Fucoxanthin metabolite


Wako Catalog No. 067-05631   (10 mg); #063-05633   (100 mg)


Fucoxanthinol is the deacetylated form of Fucoxanthin. Fucoxanthin, a major carotenoid in edible brown algae is hydrolyzed into fucoxanthinol in the gastrointestinal tract before absorption in the intestine. Various bioactivation of Fucoxanthin is assumed to be due to that of Fucoxantinol. Furthermore, Fucoxanthinol exhibited suppressive effects on lipid accumulation during adipocyte differentiation. The suppressive effect of fucoxanthinol was stronger than that of fucoxanthin.
