C3 works synergistically with L-Theanine, which is also in this formula, to promote relaxation and cognition in dogs. L-Theanine supports calming and relaxation, reduces irritability and low mood states. This natural occurring amino acid is found in green tea, and is a derivative of glutamic acid, a neurotransmitter in the brain. It can help the body produce Dopamine, GABA and Tryptophan, other calming amino acids, and helps bring certain neurotransmitters into better balance.

Without Thiamine, dogs exhibit mental confusion, muscular weakness, muscle spasms, nervousness, as well as weight and appetite loss during times of stress.
