Summary

Purpose: Energy drinks (EDs) are nonalcoholic beverages whose main ingredients are sugar, taurine, and caffeine. Their consumption is rising worldwide, with only few conflicting studies examining their vascular effects in young adults. We evaluated microvascular reactivity (MR) before and after ED in young healthy male volunteers.

Methods: Systemic MR was evaluated in the skin of the forearm using laser speckle contrast imaging with acetylcholine (ACh) iontophoresis before, 90 and 180 minutes after the consumption of one can of ED or the same volume of water (control), followed by postocclusive reactive hyperemia (PORH).
