Support mental clarity with NOW® True Focus™. Norepinephrine and dopamine are key neurotransmitters for the maintenance of alertness and mental acuity for promoting a feeling of general well-being. These two neurotransmitters are produced in the body from the amino acid precursors L-tyrosine and L-phenylalanine. This conversion process also requires vitamin C and B-6 as cofactors. NOW True Focus combines these important nutrients with other ingredients like Ginkgo biloba and DMAE to maximize mental agility without any stimulating side effects.
