This product's exact composition (what "GAC" refers to specifically) wasn't independently confirmed against a primary source in this research pass — treat any specific benefit claim with caution until the actual formula is confirmed directly with the supplier.
Glutamine, Arginine, Carnitine — three aminos with different jobs. Glutamine supports gut and immune-cell fuel, arginine is a precursor to nitric oxide (linked to blood flow), carnitine supports fatty-acid transport for energy. Recovery/circulation-focused rather than one mechanism.
