N.O. Might Boost Endurance

Supplements containing the amino acid L-Arginine are typically used by strength athletes for pump promotion. New research from the University of Exeter suggests that N.O. boosting supplements might significantly increase stamina during high-intensity exercises like cycling, running or swimming. The arginine-containing N.O. booster scientists analyzed improved race performance between 1% and 2%.

But if your goal is to beat a personal best, a supplement like Essential Amino Energy might offer the boost you need to succeed.
