Kaempferol
Kaempferol, a plant flavonoid, is found in many supplements especially fat burners. Its inclusion in fat burners is due to evidence showing metabolism enhancement. Its mode of action involves increases in cellular energy expedenture via increased cAMP generation. Not only that, but studies show that Kaempferol increases T3 production - a thyroid hormone capable of increasing basal metabolic rate.
Interestingly enough and in addition to its lipolytic properties, a new study conducted on Kaempferol at Jagiellonian University School of Medicine, Krakow - Poland, showed positive cardiovascular benefits. kaempferol appeared to inhibit the conversion of Angiotensin I to Angiotensin II in a dose-dependent manner. Since the peptide angiotensin II is a potent vasoconstrictor (constricts blood vessels), the inhibition of it via Kaempferol may help in maintainig healthy blood pressure. The researchers concluded that this study may help in designing a new class of cardiovascular drugs - ACE inhibitors.
