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.

I'm currently taking about 10,000 mg of Ester-C each day to get over a virus. Ester-C is easy on the stomach, and has been shown to raise blood levels of Vitamin C over a longer period than more acid formulations.

I take high dose of vitamin C, at least 2-3g/day. this formula is easier on the stomach and big package of 500mg means I can spread the dose all over the day.
