How does NSI® Advan-C® 500 mg 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.

NSI® Advan-C® 500 mg 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® 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.

NSI® Advan-C®500 mg 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
