Expiration Date:Expiration Date
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.

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.

I buy this product from iHerb because it is 500 mg which I can't find that potency here in Australia. I drink a fair amount of alcohol and take this product daily. The price is worth buying it from iHerb.
Works for Parkinson's!
Posted by Reviewer1797456 on Mar 08, 2017
Gave it to a man in his late 70s who was developing the typical Parkinson's symptoms after reading that HIGH DOSE B1 is very effective in such cases. Within days he was thinking clearer, speaking clearer, and balance was better, just like they said. Look up the articles, it's for real. 3 a day worked for him, but they say to go up to 5 a day if need be.

My husband uses these every night, they help him sleep. They were not available locally so I searched and found your company and we have been very satisfied and appreciate the reminders.
