Amino Complex: A Foundational EAA & BCAA Formula for Peak Performance

Thorne’s Amino Complex is an elite, NSF Certified for SportĀ® blend of essential amino acids (EAAs) designed to fuel muscle growth, optimize recovery, and enhance energy production. Featuring a clinically validated 2:1:1 ratio of branched-chain amino acids (BCAAs), this formula provides the fundamental building blocks for muscle protein synthesis in a great-tasting, easily mixed berry-flavored powder. It is a clean, effective, and sugar-free choice for athletes or anyone looking to maximize the benefits of their training, support lean muscle mass, and promote cellular energy.*

How It Works: The Building Blocks of Muscle and Energy

Amino acids are the foundation of protein and are essential for countless physiological functions. This formula provides a comprehensive profile of EAAs, which the body cannot produce on its own, with a special emphasis on BCAAs.

Stimulating Muscle Protein Synthesis
The BCAAs—leucine, isoleucine, and valine—are crucial for regulating muscle metabolism. Leucine, in particular, acts as a powerful signaling molecule that initiates muscle protein synthesis, the process of repairing and building new muscle tissue. By providing a potent dose in the research-backed 2:1:1 ratio, Amino Complex kick-starts the recovery process, helping to reduce muscle soreness and promote the growth of lean muscle mass, making it an ideal supplement to consume before, during, or after a workout.*

Enhancing Energy and Endurance
In addition to their role in recovery, amino acids can also be used as a direct fuel source by the muscles during prolonged exercise. This helps to prevent muscle breakdown (catabolism), preserve glycogen stores, and delay the onset of fatigue. By supporting both muscle repair and cellular energy, Amino Complex helps you train harder, recover faster, and achieve your performance goals.*

  • Promotes the repair and growth of lean muscle mass*
  • Enhances muscle recovery and helps reduce post-workout soreness*
  • Supports energy production and increases muscular endurance*
  • Features a clinically validated 2:1:1 ratio of BCAAs*
  • NSF Certified for SportĀ®, trusted for purity and safety
