Possible L-Tyrosine Side Effects

L-tyrosine is one of the amino acids that are important for protein and neurotransmitter synthesis in your body.

At present, it is usually taken as a dietary supplement for relieving stress, depression and in promoting general well being. It is also being taken as a supplement for body building, weight loss, and promoting skin health. If you are taking these supplements, possible L-tyrosine side effects would probably be one of your major concerns.

L-tyrosine is not considered as an essential amino acid mainly because your body can synthesize this amino acid from phenylalanine (a naturally occurring non-essential amino acid). In usual conditions, the body can produce enough L-tyrosine from L-phenyalanine. However, several factors wherein your body may require additional sources of amino acids from dietary sources to meet your physiological demands. For instance, L-tyrosine becomes an essential nutrient for those with phenylketonuria (those that are not able to metabolize phenyalanine).
