Amino Acids for Muscle Health
Supplementing with Protein’s Building Blocks
Our bodies use 20 different amino acids to form the proteins required for cells to function. Nine of these are essential amino acids, meaning they aren't made by our bodies and must be obtained through diet. The branched chain amino acids in this family of products encourage protein synthesis in skeletal muscle and liver, promote muscle function, support exercise performance and muscle recovery, and support healthy brain and immune function.
4 Reasons Why Everyone Should Take Our Amino Acids
- Maintain muscle mass
- Enhance exercise performance & recovery
- Inhibit muscle soreness & fatigue
- Promote mental clarity & focus

Branched Chain Amino Acids
The branched-chain amino acids (BCAAs) L-valine, L-leucine and L-isoleucine are essential nutrients that must be obtained through your diet. BCAAs are popular with fitness enthusiasts, because they help maintain and build muscle strength and endurance. They also support a healthy immune system.

Other Amino Acids
Amino acids have uses beyond fitness and immune health. They play a vital role in metabolism and maintaining a healthy nervous system. L-Theanine, an amino acid found in tea leaves, produces calming, mood-supporting benefits. Taurine (which we offer in capsule and powder form) and carnitine, an amino acid derivative, support a healthy heart and brain.
