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. Vitamin C has powerful antioxidant properties and promotes the production of collagen required for healthy gums, skin and cardiovascular function and protection from free radical damage. 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 is also important to the formation and maintenance of collagen, which in turn is significant to the health of skin, ligaments, tendons and blood vessels. 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. These bioflavonoids may also contribute to capillary and collagen health. 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

"This Vit C is noticably more effective than simple ascorbic acid. Prior to taking this product, I had been putting ascorbic acid powder in tea and consuming with few noticeable results. After the first night that I took this Vit C with Quercetin and Citrus Bioflavonoids, however, I woke up better rested and with no congestion. The cofactors in this product seem to greatly help its bioavailability. For the price, you can't beat it. You might want to try taking a few more capsules than the label serving size and see if you continue to see improvement. My guess is that many of us are very deficient in Vit C."

"The best Vitamin C supplement I have ever found and I have been taking vit C (and looking at available products) for 30 years. This C is absorbed by the body not quickly excreted in urine. The inclusion of Calcium (in an easily absorbed formula - not oyster shell) and Quercetin make this the best supplement to add to the Vit C of your multi-vitamin."

"I was taking 2 capsules at a time (1000 mg) but my stomach can't tolerate it. I've cut down to one capsule (500mg) per meal and that seems to help but I want to take in more C than that on a daily basis. Not too happy with it. The capsule is quite large and my 12 year old, who can swallow any tablet or capsule, can't swallow this one. I supplement with liquid C."

"I take this product because the ingredient combination is superb. Quercetin helps with histamine/allergic responses and coupled with the other bioflavonoids, help with capillary integrity and other great health benefits. It was a real plus to find Vitamin C, quercetin and bioflavonoids combined into a single product. I love the neat yellowish color of the capsules, compliments of the quercetin. The quality is readily apparent when you open the bottle."

"Any time anyone in my famils feels something "coming on" like itchy nose or throat, sneezing, runny nose, etc, we take a couple of these every few hours and usually the symptoms go away. I always keep some on hand. This is a great value for Vit C w/Quercitin. Much better than the stuff at the vitamin stores."

"Advance C is the same idea as Ester C, only with the PR of NSI/Vitacost. So purchase which ever one is selling for less. Advance C is priced lower then Ester C, for the time being) Your body needs Vitamin C, the more the better, however you have to make sure you don’t take to much, and the way to know that, is if you take let say 10 grams a day and you developed a diarrhea, then you know you are taking to much and reduce it somewhat until your body is running smoothly. Things I take with it: Calcium, Magnesium, vitamin D (all in one), B complex, Synergy (multi vitamin version 2), Advance C, acetyl L Carnitine, and NSI Organic Cold-Milled Flaxseed"
