Cognitive Aminos

Age-related decreases in levels of several amino acids compromise cognitive function. Amino acids are important intermediates in the production of neurotransmitters in the brain and are involved in neuromodulating activities. l-Tyrosine is an amino acid naturally synthesized in the body. It is the precursor of the neurotransmitters L-dopa, dopamine, norepinephrine and epinephrine, supporting mood and mental clarity. dl-Phenylalanine provides a mixture of two essential amino acids, d-phenylalanine and l-phenylalanine. In the body, l-phenylalanine converts to tyrosine, enhancing neurotransmitter support. A separate pathway allows both d- and l-phenylalanine to support levels of the mood-elevating compound phenylethylamine, a function not provided by l-tyrosine. Taurine is considered an inhibitory amino acid, helping to maintain healthy glutamate and other excitatory amino acid activity in the brain. This provides neuroprotective action important for maintaining healthy brain cell functio
