Source Naturals, Niacin 250, Time Released, 250 Tablets11 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.

Note: Niacin may cause temporary flushing, tingling, skin reddening, and sensations of heat, especially if taken on an empty stomach. This is a natural and harmless reaction. Niacin 250 is time released to minimize the intensity of the flushing response, which varies from person to person.

iHerb Customer Reviews
I've been taking this same niacin for years, waiting for the flushing to subside or stop since it is a Timed Release Niacin. This has not happened yet. I experience horrible head throbbing and rash producing flushing. I'm looking for a different extended release niacin.
Terrible product. I have been taking sustained release niacin for years and have never had one that exhibited such uncomfortable flushing.
