The formulation includes Vitamin B6, Electrolyte Blend, L-Leucine, L-Glutamine, L-Isoleucine, L-Valine, and Citrulline Malate. These components are structured to provide muscle fuel and hydration support during physical exertion.

Amino acids like leucine and valine contribute to metabolic fuel utilization in muscle tissue. While citrulline malate supports blood flow and ATP production, the one-gram dosage is relatively low compared to clinical performance benchmarks.
