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.

It made me too energetic and jittery like caffeine--and then I felt worse after coming down. I'm giving very small amounts to my senior dog and seems to improve her energy and reduce her Parkinson's like shaking.

I'm certain the quality of this product is just fine, but it does not dissolve in water at all. I end up choking down a gritty mess each day. I like the capsules much better for this product.
