Mental health problems and weight gain are two very real health problems that are completely and for the most part treatable, unless there is a genetic organic component which would need to be addressed by other means. And the health issues that these two problems present with are treated by doctors using drugs that other wise mimic the less expensive organically derived ingredients that are found in nature. One of these natural components is a product called L-Tyrosine. Tyrosine is a nonessential amino acid; and it doesn't have to be obtained directly through the diet. Tyrosine can be generated from one essential amino acid Phenylalanine, or it can be taken as a supplement by itself. These two amino acids work synergistically to help control brain chemistry and some of the mental health issues that are prevalent as discussed earlier.

L-Tyrosine can be derived from the diet; some good sources are dairy products, meats, fish, wheat, and oats. The Tyrosine derived from the diet, and that which is taken as a supplement is an immediate precursor to the (the feel good) dopamine family of hormones; it is converted into L-dopa, norepinephrine, and epinephrine (catechol derivatives), which are three key neurotransmitters (chemicals that transmit signals between nerve cells). Because some antidepressant drugs work by raising levels of norepinephrine, various combinations of Tyrosine and other amino acids have been tried as possible alternatives to drug treatment for depression and appetite control. Tyrosine is also the immediate precursor to the thyroid hormone thyroxin which is a major component of in weight control process. In the case of thyroid dysfunction (hypothyroidism, which has a direct effect on weight loss), therapeutic doses of Tyrosine may have an impact upon your thyroid hormone production and basal metabolism, assisting in weight loss. The route and formation of these catechols is through the change of Tyrosine into Tyramine, and the subsequent conversion into L-dopa.

Tyrosine has also been found to be useful in treating attention deficit disorders, addictions, depression, sexual dysfunction, fatigue and to control appetite. As stated Tyrosine is important because it's an essential precursor to production of several critical chemicals called neurotransmitters, which transmit "messages" in the brain. These, along with serotonin, are among the most important chemicals in the body in terms of the multitude of mental and physical processes they influence your appetite, your mood your arousal level and much more. Many of the older weight loss products that contained an ingredient called ephedra worked (in one respect) by also stimulating the release norepinephrine. And since stress and 'over use' of norepinephrine by the body can slow the weight loss process, it is very important that the production remain at peak levels! This is where Tyrosine steps in to reload norepinephrine stores that are depleted by chronic stress. Tyrosine can also help you to feel more energetic in general, providing a boost in mental energy, it acts as an overall 'pick me up'! Vitamin B6, folic acid, and copper are necessary for conversion of Tyrosine into the neurotransmitters so taking a good multivitamin and mineral product with meals throughout the day would be prudent. Tyrosine has even been taken to help those with PKU, but using it for this would require the input of a trained physician. Those using monoamine oxidase (MAO) inhibitor drugs for the treatment of depression should avoid taking Tyrosine as it can cause high blood pressure.
