Product Description
You train hard. But here's what most athletes don't realize: when you push your body to the limit, it starts breaking down your own muscle tissue for fuel. Your body is literally eating itself to keep going. The pros know this, which is why they don't wait until after the workout to protect their gains.
Thorne Amino Complex is the clinically-validated EAA and BCAA formula trusted by 100+ pro sports teams to protect muscle, accelerate recovery, and keep you building strength session after session.
What Makes It Different
Complete Essential Amino Acid Profile Nine essential amino acids your body can't make on its own, delivered in the exact ratios proven to trigger muscle protein synthesis and stop muscle breakdown during training.
Clinically-Proven BCAA Ratio High in leucine, isoleucine, and valine—the three amino acids that signal your muscles to grow stronger instead of breaking down when you push hard.
NSF Certified for Sport Tested for banned substances and verified for what's on the label, which is why U.S. National Teams and elite athletes trust it when everything's on the line.
Here's the science made simple: amino acids are the building blocks that make up protein in your muscles. When you train, your body needs these building blocks to repair damage and build new muscle. But your body can't produce the nine essential amino acids on its own. Without them, you're breaking down more muscle than you're building. Thorne's formula delivers all nine EAAs plus extra BCAAs to flip that switch—stopping breakdown and accelerating growth.
How to Use It: Pre or Post-Workout: Mix 1 scoop (or 1 packet) with 8 oz of water 30 minutes before training or immediately after to protect and rebuild muscle. Training Days: Take 1-2 servings daily depending on workout intensity and duration. Pro Tip: Mix with cold water and shake vigorously for 20 seconds—amino acids don't dissolve instantly, so give it time to fully blend.
This isn't guesswork. Thorne is chosen by champions and trusted by over 100 professional sports teams, including U.S. National Teams. Athletes report faster recovery, reduced muscle soreness, and the ability to train harder more frequently.
Stop breaking down what you worked so hard to build. This is your muscles' protection plan.

Thorne Amino Complex FAQ's
Everything you need to know before getting started.
It provides all nine essential amino acids (EAAs) including high doses of BCAAs that your body can't produce. These amino acids signal your muscles to stop breaking down during exercise and start building new muscle tissue instead, while also fueling cellular energy production to reduce fatigue.
BCAAs (branched-chain amino acids) are leucine, isoleucine, and valine—three essential amino acids that make up a large portion of muscle protein. During intense training, your body breaks down muscle to use BCAAs for fuel, so supplementing prevents this muscle loss and promotes growth.
No. This formula contains only amino acids and is naturally sweetened with stevia. It won't interfere with sleep if taken in the evening and can be stacked with your pre-workout supplement.
