Branched-Chain Amino Acids, or BCAAs, are essential amino acids that play a key role in muscle metabolism and recovery. This blend mainly comes from fermentation of corn or poultry, depending on supply, and is quickly ready for use by muscle tissue. This formula also includes electrolytes and other hydration focused components to support fluid balance and muscle function during activity.

Branched-Chain Amino Acids help with muscle protein synthesis and support recovery after exercise. They take part in energy related processes that could influence endurance and post exercise soreness, helping to sustain performance during training. Also, electrolytes in the product help regulate hydration and support normal muscle contraction and nerve signalling during activity. This supplement isn't meant to diagnose, treat, cure, or prevent any disease.
