Kavinace contains 4-amino-3-phenylbutyric acid and Taurine to help support inhibitory neurotransmitters. Taurine functions as an inhibitory amino acid, acts as a GABA agonist, may increase GABA synthesis, prevent GABA breakdown and block GABA reuptake. All of these effects enhance GABA function. 4-amino-3-phenylbutyric acid is a GABA derivative that agonizes GABA receptors and easily crosses the blood-brain barrier.
