Vegavero L-Arginine L-Citrulline Complex High Strength 4200 mg | with Beetroot Extract | Natural Pre-Workout & Nitric Oxide Booster | Amino Acids from Fermentation | NO Additives, Vegan & Lab-Tested
EXPERIENCE A POWERFUL MUSCLE PUMP: Citrulline is converted into Arginine which in turn induces nitric oxide formation. This compound facilitates blood flow, thus leading to a better muscle pump. Research shows that combining the two amino acids can significantly increase efficacy in nitric oxide production. Lastly, we added beetroot, a source of dietary nitrates, that the body can also convert to nitric oxide to support the effect even more.
