Source Naturals, Niacinamide B-3, 100 mg, 250 Tablets8 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.

Niacinamide, also known as vitamin B-3, functions in over 50 metabolic reactions, most of which are enzymatic. Its bioactive forms - NAD+, NADH, NADP, and NADPH - play important roles as catalysts in the energy production process in the cells, the breakdown of proteins and fatty acids, the synthesis of fatty acids, and the formation of steroid hormones and red blood cells.

iHerb Customer Reviews
Very effective for calming nerves and anxiety, without inducing fatigue or dulling one's mind (works at doses from 300 mg to 600 mg three times a day). It also works well in reducing arthritic pain (at doses as low as 300 mg once a day). But, people should know that this form of vitamin B3 does not effect cholesterol levels--for that, you need the Niacin form.
very good producto but recomended 500mg
