Source Naturals, L-Tyrosine, Free-Form Powder, 3.53 oz (100 g)25 Reviews
Expiration Date: May 2018
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.

- Amino Acid Supplement
L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, as well as for thyroid hormones and enkephalins, special peptides which subdue messages of physical discomfort. Tyrosine is also a constituent of amino sugars (glycosaminoglycans), special compounds which have important roles throughout the body.

iHerb Customer Reviews
I use this because it seems to help stabilize my moods. I Used to take Wellbutrin for depression, and it worked well, but when I lost my insurance I had to find a lower cost alternative that would boost some of the same neurotransmitters as Wellbutrin did. This amino acid was recommended to me. It doesn't replace the effects of the Wellbutrin for me, but it does a good job. I use 1/4 teaspoon with breakfast, and sometimes with lunch as well. I like the freeform powder because it allows custom dosages, and is cheaper and absorbs very fast. This amino acid may keep you up at night, so don't take it before bed. Good luck.
The cost of powder (non encapsulated) amino acids is decidedly less than the other forms. L-Tyrosine is tasteless, and, therefore, I find it very palatable and easy to take. A good deal for a high quality product.
