CitraPeak is a premium, clinically studied form of glucosyl hesperidin. It's a unique additive with all the biological functions of standard hesperidin — like vasodilation and pump effects — and none of the solubility issues. As the industry's first fully soluble glucosyl hesperidin, it is easy to combine into your pre-workout formulations. CitraPeak activates quickly, making it an ideal, one-of-a-kind pump ingredient for pre-workout applications. Glucosyl hesperidin comes from citruses and helps increase circulation. This helps increase energy and physical output during a workout, making it an ideal ingredient in pre-workout formulas. A fully soluble glucosyl hesperidin, such as CitraPeak™, has no taste or in mouthfeel, is safe to use, and helps athletes be at their best.
