LifeSource Vitamins Ultra Amino Acid Complex — ½ Scoop (10 g) Serving — Amino + Protein Support for Performance & Recovery*
Our Ultra Amino Acid Complex combines peptide-bound proteins with targeted free amino acids in a powder to support muscle repair and recovery, promote protein synthesis, reduce perceived post-exercise soreness, support metabolic balance, provide essential and conditionally essential amino acid nutrition, promote lean mass and strength with training, support immune cell fuel under stress, promote glucose/insulin dynamics, provide vascular function support via arginine pathways, promote mood and sleep via tryptophan pathways, and support overall performance and resilience* — while respecting evidence-based use. Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity and potency by LifeSource Vitamins.
