Tyrosine is considered a non-essential amino acid, meaning that our body can make it from another amino acid, phenylalanine. That being said, it can also be found in a variety of foods, including wheat germ, oats, cheese and other dairy products, pork, turkey, chicken and other wild game. Tyrosine or L-tyrosine, can also be taken as a supplement. PKU is a condition in which individuals cannot make tyrosine from phenylalanine, in these cases, supplementation is necessary. |
One of the more important medicinal uses of tyrosine, comes from its ability to be converted to the following neurotransmitters: dopamine, epinephrine and norepinephrine. These neurotransmitters play a integral role in memory, attention and problem solving, depression and mood, as well as our stress response. Studies have shown that tyrosine, most likely due to its ability to increase the levels of the aforementioned neurotransmitters, may have the ability to fight fatigue and improve memory and mental functioning, particularly under the influence of environmental stressors, including sleep deprivation due to stress. It has also been shown to calm anxiety and help to improve mood and outlook.
Tyrosine is also involved in the synthesis of the thyroid hormone thyroxine. It is commonly recommended that individuals suffering from thyroid dysfunction, supplement with tyrosine to increase metabolic activity and help to alleviate hypothyroid symptoms. As a substance that increases or up-regulates norepinephrine, tyrosine can also cause relatively quick and signficant increases on energy, especially useful for individuals suffering from chronic fatigue or fibromyalgia.
Tyrosine can be found in capsule form, either alone or in combination with other amino-acids, or supplements formulated to support thyroid, mood, energy and attention. Tyrosine is considered safe at high doses. Some research has shown it has been associated with increased blood pressure in some individuals. If you have moderately high blood pressure or are at risk for high blood pressure, consult a qualified healthcare practitioner before supplementing with tyrosine and have your blood pressure checked regularly. |
