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-Theanine is a unique amino acid found almost exclusively in the tea plant (Camellia sinensis) and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that L-theanine crosses the blood brain barrier, increases dopamine and GABA levels in the brain and inhibits the stimulatory properties of caffeine. Human studies have shown that taking L-theanine results in the emission of brain waves associated with a state of relaxation.

I have ADD. I was reading that people with ADD have a deficiency of the neural transmitter dopamine. I find this L-Theanine product works great to give me greater focus and concentration. I take about three a day.

I've been taking 2 of these a night for almost a year and swear by them for the relief of anxiety and depression. They don't make me feel drowsy or hyperactive, they just gently make me feel better. It can take a week or two for them to take full effect. I haven't noticed any side effects and don't see myself ever stopping them unless I have to. I take them along with 2 x L-Tryptophan, also from source naturals.
