Polyphenols, antioxidants found in plants, boost energy without caffeine. In a study from 2011, rats that consumed aqueous mixtures of 25 mg/d of polyphenols (catachin, chlorogenic acid, ellagic acid and quercetin) showed a significant increase in swimming time, and polyphenols increased the concentration of ATP.
elevATP™, a proprietary combination of a water extract of ancient peat (fossilized plants) and apple extract from FutureCeuticals, caused an increase in blood levels of ATP by 64 percent without increasing oxidative stress in healthy adults.
Capsiatra Dihydrocapsiate is similar to capsaicin—the potent ingredient in hot peppers—but is not at pungent and does not elevate heart rate or blood pressure.
