Expiration Date: Aug 2017
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

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.
