What Is FUCOXANTHIN?

Supplement

Fucoxanthin is a marine carotenoid found primarily in brown seaweeds and diatoms that exhibits unique antioxidant properties. Research suggests it may support metabolic health through effects on adipose tissue, increasing energy expenditure and promoting fat oxidation, particularly through its metabolites fucoxanthinol and amarouciaxanthin A. Studies indicate potential benefits for weight management, liver health, and antioxidant protection.
