Expiration Date: Jun 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.

B1 is intimately involved in many aspects of nerve health and function. The active co-enzyme form of B-1, thiamin pyrophosphate (TPP), is necessary for energy production and is essential for the formation of acetylcholine, a major neurotransmitter. Magnesium plays a role in neuromuscular transmission and activity, promoting muscle relaxation. A highly processed "junk food" diet, excessive alcohol intake, and exhaustive exercise may increase the need for B-1.

iHerb Customer Reviews
Vit B-1 is very valuable for mental stresses. I take 250-500mg daily. Take an equal of Vit C to avoid tooth brittleness. The tablets are pretty large but can be split into 1/2's or 1/4's. Works well for me.
Recommended by my doctor for leg cramps. I cannot tell you enough about this product. Since I have been taking these 3 times a day for quite a while I do not have leg cramps. If on really hot days and I do too much and sweat a lot I will sometimes need to take an extra tablet, and the leg cramps are gone. No sleepless nights walking the floors anymore. I recommend them to anyone I talk to that has leg cramps and cannot get quinine anymore.
