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.
Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. It is a required cofactor for an estimated 300 enzymes. Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.
Mix 1/4 level teaspoon of powder into at least 6 oz. of cold water or clear liquid. Take once daily with a meal. Pure Magnesium Oxide Powder can increase the temperature of liquids upon contact; therefore, the recommended serving must be mixed into at least 6 oz. of cold liquid to neutralize this reaction prior to ingestion.
