How does NSI® Advan-C® with Citrus Bioflavonoids work?
This formula 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. It is specially formulated to supply optimal amounts of vitamin C to support a healthy immune system. It also promotes the production of collagen required for healthy gums, skin and cardiovascular health.

Unlike regular vitamin C, which can be harsh on the stomach, NSI® Advan-C® with Citrus Bioflavonoids is acid-neutralized to be non-irritating to the 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.

The citrus bioflavonoids in this formula are polyphenolic compounds which are found naturally in the rinds of oranges, lemons, grapefruits and tangerines. They are believed to work synergistically with vitamin C and may contribute to capillary and collagen health.

NSI® Advan-C® with Citrus Bioflavonoids is better because it:
-- Is a superior vitamin C complex for a greater value
-- Is gentler to the digestive system than common vitamin C
-- Allows for greater absorption and retention of the vitamin’s nutritional value
