I use this to help with thyroid function. When I use it, my low body temp (~96) goes up to 97.5 and higher, a sure sign that the thyroid is functioning better. L-tyrosine is great.
L-Tyrosine really helped my brain, Jarrow best I know of.

At the recommendation of a holisticly inclined physician, I started taking this product along with P-5-P to help my brain recover normal function after years of damage due to Lyme disease. Aggressive treatment had stopped the disease, and I had regained a great deal of function. But the brain takes a long time to heal, and I particularly had trouble with processing incoming sensory data and in initiating response. To my surprise, L-Tyrosine turned that around. I wasn't sure at first, as I started a couple of other things at the same time. But when I stopped for a week or so, I really noticed the difference. Started up again, and immediately noticed the difference. My mood improved as well. If you are dealing with brain issues due to Lyme disease, your needs may differ as this disease affects everyone somewhat differently, especially when it comes to the brain. But for me, this sure helped.

i love Jarrow and this Tyrosine has made a big difference in my energy. i excercise a lot and was having major energy slumps and poor exercise recovery. this has helped me to be more stable and energized. I was ADDICTED to caffeine for energy and this has gotten me completely off coffee! it's a much better, natural energy lift/buzz. I use 1000mg on an empty stomach before exercise or when i need an energy lift.

Over the last three months I have been taking one capsule in the morning and one before sleep and my latest blood workup show a nice improvement in my TSH numbers.
A good product, not to be mixed with other supplements

This product is very good quality, but I recommend not taking it in conjunction with other, similar supplements. When I combine it with the other supplements, I get a headache, but when I take it alone, it has the effect of an anti-depressant, without the side-effects of prescription medication.
