Sentinel L-Arginine L-Ornithine is a dietary supplement containing an amino acid complex with 500mg of L-Arginine and 250mg of L-Ornithine per capsule. This supplement comes in a bottle of 50 capsules and is designed to support protein synthesis and muscle function. L-Arginine and L-Ornithine are amino acids that work synergistically in the body. L-Arginine is a semi-essential amino acid involved in protein synthesis, wound healing, and nitric oxide production. L-Ornithine supports the urea cycle and helps remove excess nitrogen from the body. Together, these amino acids may help support muscle recovery, protein metabolism, and overall athletic performance. As with any supplement, consult a healthcare provider before use.
