Guardian Aminos

First off, BCAA stands for Branched Chain Amino Acids. Amino Acids ( L-Leucine, L-Isoleucine, and L-Valine) are essential for repair and recovery from strenuous exercise, whether it be a sport or even a long hike in the heat. Our formula includes electrolytes, Sodium and Potassium, for extra hydration.

Our Athletes tested our BCAAs against some other brands, and found that they recovered faster and sustained more muscle on a caloric deficit diet with Guardian Aminos.

We also included a gram of Glutamine in each serving. Did you know Glutamine is the most common Amino Acid found in your muscles? Glutamine is also greatly depleted during intense exercise, which can decrease your strength, endurance, and recovery.

When you workout in the gym, play a sport, or engage in cardiovascular exercise, you are tearing your muscle fibers. This is what makes you sore, especially if you pushed yourself. BCAAs rapidly absorb into your muscle to repair what you broke down during your workout.
