Fucoxanthin is a carotenoid that occurs naturally in certain algae. It significantly reduces abdominal white adipose tissue (WAT) in mice and rats when included in their diet. Fucoxanthin increases the amount of mitochondrial uncoupling protein 1 (UCP1), a fatty acid-stimulated protein involved in respiration and thermogenesis in WAT of mice and rats. In KK-Ay mice, which are used to model obese type 2 diabetics with hyperinsulinemia, fucoxanthin reduces WAT gain and also decreases blood glucose and plasma insulin levels.

Fucoxanthin is a kind of natural pigments belonging to lutein-class in carotenoids class, accounting for over 10% of the total amount of carotenoids which contains 700 species of naturally occurring species. Its color is pale yellow to brown and it is belongs to the pigment being contained in brown algae, diatoms, golden algae and green and yellow algae. It is widely distributed among a variety of algae, marine phytoplankton, shellfish and other aquatic plants and animals. It has various pharmaceutical effects such as anti-tumor, anti-inflammatory, anti-oxidant, causing weight loss, protecting nerve cell, increasing the content of ARA(arachidonic acid) and DHA (docosahexaenoic acid) in mice; it is widely spread in market of skin care, cosmetics product and the health care.
