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 free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine, and epinephrine, for thyroid hormones, and for enkephalins, special peptides which subdue messages of physical discomfort. L-Tyrosine is also a precursor for the protective skin pigment melanin.

I've been suffering from depression for the last 10 years and this product helped me to laugh a bit. It gave me the energy that I lack for the whole of my life. Now it's easier to communicate to laugh and to do sport. I was so lethargic to do anything. But it contains wheat&gluten be carefull if you are allergic to those.

...you really have to understand yourself (to know that this stuff might help). First few days were really weird, my body had a tingly feeling all over. I'm taking 1 pill a day, sometimes 2 and it keeps my emotions quite stable. I'm happier and I don't worry about stupid stuff anymore. Oh and it might keep you really awake the first week or two.
