About Brown seaweed carotenoid
A carotenoid from brown seaweed (e.g. wakame). The most-cited human weight-loss trial used Xanthigen, a fucoxanthin + pomegranate-seed-oil combination, so the effect cannot be attributed to fucoxanthin alone; remaining data are animal/mechanistic (thermogenesis via UCP1). Standalone human evidence is insufficient.
