Synopsis

Rating (out of 5): 2

Fucoxanthin is a carotenoid found mainly in brown seaweeds such as wakame and hijiki. It has attracted interest for its potential anti-obesity effects, largely based on preclinical studies and a small number of human trials. Laboratory research in rodents suggests that fucoxanthin may promote weight loss by increasing the expression of genes involved in fat metabolism and by stimulating thermogenesis in white adipose tissue. These effects are thought to result from the upregulation of uncoupling protein 1 (UCP1), which increases energy expenditure. A handful of small-scale randomized controlled trials in humans have reported modest reductions in body weight and body fat when fucoxanthin is consumed as part of a supplement blend, often with pomegranate seed oil or other compounds. However, the number of participants in these studies is generally low, and many of the trials have methodological limitations, such as short duration or lack of clear dietary control. No large, high-quality clinical trials have definitively established the efficacy of fucoxanthin for weight loss in humans. Therefore, while there is some early scientific evidence suggesting a potential benefit, it is not strong or conclusive at this time. The use of fucoxanthin for weight loss is not based on traditional medicine, but rather on recent pharmacological and nutritional research.
