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.
How It Works: N-Acetyl-Cysteine (NAC) is a stable form of the non-essential amino acid L-Cysteine. Cysteine is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures. Although NAC possesses its own free radical scavenging activity, its primary function in the body is to supply Cysteine necessary for glutathione synthesis and replenishment. This unique formula also contains Molybdenum, an essential trace element that functions as a cofactor in many biochemical reactions, and Selenium, another trace mineral that supports glutathione production.
Take 1 capsule twice daily, or as directed by your healthcare practitioner.
Cellulose (capsule), stearic acid (vegetable source) and citric acid.
Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.
Cautions/Interactions: NAC may interact with certain pharmaceutical medications including ACE inhibitors and angina medications such as nitroglycerin and isosorbide. NAC may also interact with activated charcoal.
