A New Superior Vitamin C Complex for a better value! New Advan-C® provides beneficial amounts of vitamin C in a non-acidic form that is gentle to the digestive system and more highly absorbable than common vitamin C. How does NSI® Advan-C®with Quercetin & Bioflavonoids work? Vitamin C is a water-soluble vitamin that is essential for the overall normal growth and development of the body. It is required for the maintenance of healthy cartilage, bones, teeth and gums. Vitamin C also supports the health of your immune system, vision and cardiovascular system. It is the most important water-soluble antioxidant in the body, fighting the damaging effects of free radicals. As vital as this nutrient is, it is not stored in the body and therefore must be replaced regularly. Smoking, stress and certain illnesses can contribute to reduced levels. Since the body cannot make vitamin C on its own, it must be acquired through either diet or supplementation. NSI® Advan-C® is specially formulated to supply optimal amounts of the vitamin to the body and also facilitates its absorption and retention. Unlike regular vitamin C, which can be harsh on the stomach, NSI® Advan-C® is acid-neutralized, meaning that it is non-irritating to your digestive system. It is produced using an exclusive process that combines ascorbic acid with a proprietary patent pending mineral complex and C metabolites, including L-Calcium Threonate, for an all-natural pH-neutral formula. This gentle yet effective supplement can be safely and comfortably taken in doses up to 2,000 mg a day. NSI® Advan-C® also contains quercetin and bioflavonoids. Quercetin is a natural compound found in foods such as green tea and apples. It has both antioxidant and anti-histamine properties. Quercetin works to inhibit the production and release and of histamines, which can lead to allergy/inflammatory symptoms. The citrus bioflavonoids found in NSI® Advan-C® are polyphenolic compounds believed to work synergistically with vitamin C, providing additional antioxidant protection. They are naturally present in fruits and vegetables, particularly in the rinds of oranges, lemons, grapefruits and tangerines. NSI® Advan-C® with Quercetin and Bioflavonoids helps you to attain the recommended levels of vitamin C suggested for overall health and vitality – without the potentially irritating, acidic effects of the nutrient’s more common version. NSI® Advan-C® with Quercetin and Bioflavonoids is better because it:. Is a superior vitamin C complex for a better value. Is gentler to the digestive system than common vitamin C. Allows for greater absorption and retention of the vitamin’s nutritional value. Contains added Quercetin and Bioflavonoids for added antioxidant properties. Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"I was looking for a high-dose vitamin C product in capsule form that was more than just ascorbic acid. This filled the bill for me. I take one capsule twice a day. I'm not a health professional but I feel that should be sufficient. The capsule is a bit large but not as large as some other supplements I take, so swallowing them is not a problem. (I'm a throat cancer/radiation therapy survivor, the aftereffects of which sometimes make it difficult for me to swallow large capsules or pills)."

"I don't know how I stumbled upon this C supplement, but to say it really works is an UNDERSTATEMENT! Hayfever is much less bothersome! What relief! And I suppose that it is doing a lot of other good things. I don't have any stomach upset when I take it. I don't know if anyone else is manufacturing this combination with C but I can't see why anyone would switch to another brand. You can't beat the price, formulation of the ingredients, type of ingredients, and ease of digestibility. I'm sold - I'll be taking 2000 mg a day from now on! Thanks NSI - for a great product!"
