iHerb Customer Reviews
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.
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 take this to combine with 5-htp for anxiety. What i got is that i am not tired any more in the morning but i didnt get any boost of energy just tirednes is decreased for like 50-60 % at the morning ai am ok now , not great but OK after 3 weeks of taking. I recomend this for some little depresive periods but not for anxiety and bigger depression. ! And i rate this with 3 stars becayse it helps with tirednes and little with mood but nothing special ! And from 5-htp i dodnt get NOTHING ! its like i drink sugar pills ! Dont buy 5-htp it doesnt help at all. Beter take Tryptophan becayse i know its working.

It works as all tyrosine supplements. Sometimes it's a good booster but also can get you wired and anxious. I guess that depends on the state of your mind. If you're already anxious or worried - I don't recommend. It will not boost you, but get you more wired.

After I start taking L-tyrosine I jump out of my bed in the morning when the first alarm rings or even before that instead of pressing snooze button and slowly crawling my way out of bed with closed eyes. I can't even wait until its gets to the morning to wake up. Waking up in the morning was never been wasy before like this. This energy will continue for the rest of the day is well. Sometimes cause slight troubles sleeping though but not something to consider. An A+ supplement for anyone lacking energy due to depression or a must have supp. Side effects free. As always Jarrow formulas comes with top quality which proves by its efficacy.

These have definitely helped to regulate my thyroid, the ideal dose for me is 1.5 caps per day. However, as they are in a non-vegetarian cap, and I am allergic to animal products, I have to open the cap into juice, so will probably switch next when I run out.
