How fucoxanthin is different from other ingredients in the weight management category:
Fucoxanthin is a clinically proven non-stimulant thermogenic.† Unlike many popular stimulant-type metabolism enhacers ( e.g. ephedra, caffeine, guarana), fucoxanthin has no effect on the sympathetic nervous system and can be taken without concerns of cardiovascular exhaustion or blood pressure deregulation.
The mode of action of fucoxanthin is such that it bypasses the nervous system and shifts energy balance from producing ATP toward thermogenesis. It occurs in the mitochondria, at the exact point where the energy becomes available for either capturing it in the form of ATP or for heat generation. Fucoxanthin does it by upregulating production of UCP- 1(uncoupling protein 1), also known as thermogenin.
Fucoxanthin preferentially affects visceral adipose tissue ( fat tissue that surrounds internal organs in the abdominal cavity, including liver and omentum). Breakdown of visceral vs. peripheral fat is most beneficial for overall health and longevity.
Fucoxanthin has antioxidant properties that are different from other carotenoids. Unlike other carotenoids, it is active in environments with low oxygen presence (most tissues under physiological conditions have very low oxygen presence). Also, instead of donating electron, like many antioxidants, fucoxanthin donates proton. A combination of these two attributes is unique to fucoxanthin and is most likely due to its unusual chemical structure (presence of allenic bond in the carotenoid formation).
