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.
Vitamin C with citrus bioflavonoids from oranges – the way they're found in nature.
Vitamin C with flavonoids optimizes the beneficial effects of vitamin C – including support of immune function and promotion of wound healing – by replicating the way it's found in nature
Vitamin C (ascorbic acid) is a key antioxidant, protecting cells throughout the body from free radical damage. It plays an integral role in the production of cellular energy, and is essential for the proper metabolism of carbohydrates and the synthesis of fats and proteins. Vitamin C also helps break down cholesterol, promotes wound healing, and helps maintain healthy immune function. Thorne's Vitamin C with Flavonoids contains ascorbic acid and citrus flavonoids. The flavonoids are a mixture of naturally-occurring flavonoids, including rutin, hesperidin, and quercetin. And there is no corn starch contained in this supplement, as it is in many other vitamin C supplements. Although ascorbic acid will work in the body without flavonoids, it works better when accompanied by flavonoid molecules, because the bioflavonoids spare vitamin C, thus providing greater antioxidant capacity.
Vitamin C is an essential, water-soluble antioxidant that can enhance collagen stabilization. A vitamin C deficiency can result in poor collagen cross-linkage and weaker connective tissue. Vitamin C promotes wound healing because it is a cofactor in the synthesis of collagen and other connective tissue components.
Because bioflavonoids have some of the same mechanisms of action as vitamin C, they can potentiate the effect of ascorbic acid. Vitamin C and bioflavonoids both support immune function, connective tissue formation, cellular energy production, and antioxidant activity. Factors dictating a need for higher vitamin C intake include smoking, alcohol ingestion, stress, diabetes, environmental toxicity, and the use of certain medications.
Vitamin C also serves as a cofactor in the synthesis of important neurotransmitters in the body, such as dopamine and norepinephrine.
