I’ve seen L-Tyrosine in the stores before, along with a dozen other supplements that I’m really not sure their purpose is in the human body, and it can get really confusing as to what supplements you should take, what you already have enough of in your diet, and what is just plain overkill it seems. You could take every supplement under the sun and still be missing some “important nutrient”, so I wanted to dig a little deeper and see what L-Tyrosine is typically used for, both as a supplement to the diet, and as a part of the body’s natural chemical makeup.
First of all, most people get enough, or synthesize enough, L-Tyrosine, just by eating their regular diet, so supplementation is usually not recommended unless by a doctor for a particular syndrome or health issue. However, that does not mean that this amino acid is not important to your body.
Some of the therapeutic uses that people have used tyrosine for are depression, chronic fatigue syndrome, ADD and anxiety disorders, parkinsons disease, and even weight control. It is a precursor to several neurotransmitters that are important to mood and energy levels though, so the depression and fatigue syndrome theory may be partially on base. These neurotransmitters include dopamine, epinephrine, and norepinephrine.
It’s difficult to say whether it helps with any of these for real, because most of the evidence that it has helped people is anecdotal and no real studies have been carried out that I could find, but it certainly may be worth more research if you’ve been investigating this supplement for some particular health symptom you are experiencing.
Some people swear by it, that it has helped them with all the above mentioned disorders, so that makes me think there is something to it. I did not find any reported negative side effects, so if you have any of the health problems mentioned, you may want to do some further research on your own and see if maybe L-tyrosine may be a good supplementation for your diet. It also may assist with proper thyroid function, as some claim.
