Jarrow Formulas, Niacinamide, 250 mg, 100 Capsules38 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
I find I get better results taking small amounts of niacin instead (50mg or less), so will stick with that. I found 250mg of this to be way too much at once - took at night, had a fog-ache all the next day and was over-tired. Not the desired result at all. At this dose it depletes too many other things, necessitating their supplementation or increased doses to compensate - terrible if you've already had a difficult time trying to find a balance. Additionally, I've since read that niacin/niacinamide decreases thyroid hormone levels, which is true of my experience. In one small study - after a year of taking niacin, thyroid hormone levels had fallen significantly in each person. In another - thyroid hormone levels decreased in two people, and one of these two was diagnosed with hypothyroidism. Fortunately - when the niacin was discontinued for one month, thyroid hormone levels returned to normal. Please be careful. If this review was helpful to you, please click YES below - thank you.

I read an article about curing Alzheimer's with niacinamide in mice (Second Opinion newsletter, February 2009) - decided to try it - the niacinamide has helped my Mother very much, she is calmer, more alert, speaks better, more like her old self, I highly recommend it. I plan to double her niacinamide dose.
