Alternative to pure caffeine

PURENERGY from ChromaDex Corporation is a patented co-crystal ingredient comprised of caffeine and pTeroPure, a 99% pure, nature-identical pterostilbene. Laboratory tests show the product to provide sustained energy and alertness with more gradual finish, preventing the so-called ‘crash’ that many consumers experience after taking caffeinated drinks. Named the 2010 North American Most Promising Ingredient of the Year by Frost & Sullivan, the formulation is said to benefit cognitive function, antioxidant activity, heart health and weight management support.  PURENERGY and pTeroPure are manufactured by Laurus Labs.
