L-Tyrosine is a non-essential amino acid that plays an important role in the production of neurotransmitters dopamine and norepinephrine. In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.

iHerb Customer Reviews
Factoids: L-Tyrosine deficiencies are among the most common deficits seen in CFS. Tyrosine is used by the thyroid and adrenal glands to manufacture their natural hormones which regulate the body's ability to produce energy. Recommended use is 500 mg daily for depression and low body temperature. My Experience: I'm dealing with crippling fatigue and after being on Tyrosine for 10 days, have determined that three doses of a 1/2 teaspoon each (800 mg.) on an empty stomach has been a tremendous help in elevating my level of energy. It has also helped me to sweat again. No more cold nights. Though I don't have any signs of a Tyrosine deficiency, it has been a tremendous help therefore my diet must be somewhat deficient in Tyrosine. The powdered Tyrosine has no taste. It's a soft, puffy granule. I simply dump it into my mouth and chase with water. It couldn't be easier. Words of Advice: Using more than 1/2 teaspoon per dose is like having too much caffeine (in my experience). Taking it past late afternoon may keep you from falling asleep at your regular time. Enjoy!
I weigh about 215 lbs and I need to take about 4 grams of this to feel it for physical activities. It works great if taken on a completely empty stomach. An hour later I really notice a difference in football, basketball and Brazilian Jiu JitSu. But just for mental focus I need about 1 to 1 and half grams. You need to play around the dosage to get it right for you. But you must take it on a empty stomach for this to work.
This stuff works!

I noticed results within 5 days or starting this product and have been able to cut out coffee completely. I also wake up earlier with more energy and feel like it is benefiting my journey to gaining healthy body weight. For the price this product is amazing.
Very interesting, definitely useful on dull and dreary days!

I've been having a lot of motivation problems lately, but not anymore! When I take this I feel euphoric for a couple hours, and then just plain good for most of the day. Best to use it only when needed though, as I have found the effects aren't as strong or beneficial if taken daily.
Made in China

So disappointed this product is made in China. It doesn't say anywhere on the iherb website. Thought it would be the same as the other now products. You need to clearly inform people, had I known is was a product of China I would never have purchased. Waste of money.
very good now product
