L-tyrosine is an amino acid which is the precursor neurotransmitters like adrenaline, nor-adrenaline and dopamine.  However, L-tyrosine information provided by searchers depicts that it has little effect on mood and behavior. A lot of studies about L-tyrosine information have remarked that this amino acid is helpful in decreasing stress, cold, fatigue, prolonged work and sleep deprivation by reducing stress hormone levels. It also improves cognitive and physical functions in human beings. L-tyrosine is present in many proteins found in every day foods and is a part of signal transduction processes in human body. In plants, it helps the process of photosynthesis. L-tyrosine supplements are used as natural antidepressants. Till now, no L-tyrosine side effects have been shown by any L-tyrosine information. Ecstasy Effects MDMA (Ecstasy) selectively destroys axon terminals of 5-HT neurons in the brain. Many studies have remarked that dopamine plays main role in this toxicity. More or less, it is clear from studies that dopamine produces toxic oxidative species like oxygen species and quinines. But, the production of these species by dopamine is, however, yet unknown. There are many hypothesis developed about its mechanism of action, one of which I would like describe here. When MDMA is administered with the L-tyrosine supplements, L-tyrosine MDMA is produced, which has damaging effects. L-Tyrosine Effects L-tyrosine contributes to the neurodegenerative process, as it is also the precursor of dopamine. After the administration of MDMA, L-tyrosine (natural antidepressant) is seen 5-fold increased in vivo. Contrary to dopamine, tyrosine amino acid is actively ...
