L-Tyrosine is a nonessential amino acid that plays a crucial role in the production of proteins, enzymes, thyroid hormones, and melanin, as well as in the communication between nerve cells . It is naturally synthesized by the body from another amino acid, phenylalanine, and can also be obtained from certain foods such as meats, fish, eggs, dairy products, beans, nuts, oats, and wheat .
The potential benefits of L-Tyrosine supplementation include its possible effectiveness in improving mental performance, alertness, or memory, particularly under stressful conditions or during cognitively demanding tasks . Some studies have suggested that L-Tyrosine could help alleviate reduced memory under stress, as neurotransmitters like dopamine and norepinephrine, which are synthesized from tyrosine, can become depleted during stress .
