Fucoxanthin is an organic chemical compound which belongs to a group of xanthophylls. It has been found in some marine organisms, including the algae Undaria pinnatifida and Laminaria japonica and the microalgae Phaeodactylum tricornutum and Cylindrotheca closterium. Due to its unique, chiral chemical structure, which is different from the structure of most carotenoids, fucoxanthin has special properties and pharmacological effects.
Fucoxanthin is a potent antioxidant. In addition, it is believed to have antioxidant, antidiabetic, hepatoprotective and slimming properties. Studies have shown that it may affect the expression of genes associated with lipid metabolism, stimulates the activity of uncoupling protein 1 (UCP1) and regulates leptin levels. It may also enhance tissue sensitivity to insulin.
In supplementation, fucoxanthin is used most frequently as a natural and safe aid to weight loss. It is used less often for health promotion purposes. Single-ingredient formulations with fucoxanthin derived from seaweed are available on the market. It is also frequently added to multi-ingredient slimming supplements.
