By Now Foods60 Reviews
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.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

iHerb Customer Reviews
Vitamin B1 - iodine, magnesium, manganese and copper antagonist (among others) - all in some way essential for thyroid/endocrine health. High doses of B1 can therefore lead to: immune dysfunction, hypothyroidism if iodine intake is inadequate; hypothyroid/low blood sugar if manganese intake is inadequate - especially when combined with higher intakes of other less-obvious iodine/manganese antagonists such as niacin, B6, magnesium, calcium, vit C, boron, etc. Additionally, B1 is an essential cofactor for transketolase - suggest caution for people who take medications that also upregulate transketolase (e.g. asthma steroids), because more B1 may lead to depletion of other co-factors and essential nutrients (e.g. EFA's), creating a nasty catch-22 situation. B1 is also mildly anticholinergic - something to be mindful of, because for some people that can be an issue. High intake of B1 is also likely to cause/contribute to bad armpit BO.

I have Hashimoto's i.e. hypothyroidism which is accompanied by low stomach acid. B1 helps with formation of stomach acid. I feel less tired since I've been taking B1 daily.
