St John's Wort Extract standardized to contain 0.3 hypercin. Each capsule contains 500 mg GABA and 2 mg B6. GABA regulates brain and nerve cell activity by inhibiting the number of neurons firing in the brain. By inhibiting over-stimulation, GABA may help promote relaxation and ease nervous tension. Each capsule contains 500 mg of L-Tyrosine.
Tyrosine is a precursor of the neurotransmitter norepinephrine and dopamine, which regulate mood.
A lack of tyrosine in the brain can result in depression. Low plasma levels of tyrosine have been associated with hypothyroidism so this amino acid has a role to play in a healthy thyroid.
