View this orderThe 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.
Doctor's Best Sustained Release Vitamin C with PureWay-C® supplies a unique form of the essential nutrient vitamin C that contains vitamin C lipid metabolites. PureWay-C® has been studied in comparison to several other well-known forms of vitamin C. PureWay-C® has superior uptake, bioavailability and retention in cells, as well as more potent free radical scavenging capabilities than other forms of vitamin C. This increased bioavailability means PureWay-C® has the potential to more potently support healthy neuron function and enhanced immune system activity as compared to other forms of vitamin C.
Adult Use: Take 1 tablet twice daily, or as recommended by a nutritionally-informed physician.
Hydroxypropyl methylcellulose, stearic acid, magnesium stearate (vegetable source) and silicon dioxide.
Store in a cool dry place.
