Thorne Amino Complex (Lemon Flavor)
by Thorne
"All 9 essential amino acids in clinical ratios — the practitioner-grade EAA for muscle preservation and recovery with NSF Certified for Sport"
Overview
Thorne Amino Complex provides all 9 essential amino acids (EAAs) in clinically studied ratios optimized for muscle protein synthesis. The formula includes 3.6g leucine per serving — above the 2.5g leucine threshold required to maximally stimulate mTOR and muscle protein synthesis. Unlike BCAAs (which only provide 3 of 9 EAAs), a complete EAA formula provides all the building blocks needed for muscle protein synthesis. Thorne's formula is NSF Certified for Sport, making it suitable for professional and Olympic athletes. The lemon flavor is designed for intra-workout sipping.
