L-Tyrosine 500 mg
L-Tyrosine 500 mg capsule by Douglas Laboratories is an L-crystalline amino acid in supplemental form that may support neurotransmitters and stress-related performance, memory, alertness, and sense of well-being.
Tyrosine is a precursor of important neurotransmitters in the brain, such as dopamine, epinephrine (adrenaline) and norepinephrine (noradrenaline). The synthesis of these neurotransmitters is limited by the rate of tyrosine entry from plasma into the brain and competing amino acids. L-tyrosine is a conditionally essential amino acid that can be synthesized by the body from the essential amino acid phenylalanine.
Therefore, adequate tyrosine production depends on a sufficient supply of phenylalanine in the diet. However, in people that have phenylketonuria (PKU) who cannot synthesize tyrosine from phenylalanine, tyrosine is an essential amino acid.
L-Tyrosine 500 mg is indicated for individuals that want to supplement this individual amino acid.
