Works amazingly as a natural replacement for thyroid medication.

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.

I always feel awful in the morning, but 30 minutes after I take it, plus coffee, feels way better!

Used as a supplement to L-tryptophan and definitely increases its effect for helping with sleep.

I like the quality of Jarrow L Tyrosine. They are very good quality at a reasonalbe price. They help me with energy and depression.

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.

My friend swears by this product for her energy levels. She's noticed a major change. She has suffered from depression for years. I'm still trying it out for my energy levels.
