Vitamin C in fruit is naturally part of a total complex that includes ascorbic acid, bioflavonoids and co-factors that aid absorption. Alive!® Fruit Source Vitamin C is complete Vitamin C just as Mother Nature grows it. Unlike other supplements that use isolated ascorbic acid or cultured bacteria as the source of Vitamin C, Alive!® Fruit Source Vitamin C derives its entire Vitamin C content from four of Mother Nature’s most potent organic fruit sources: Organic Acerola, Organic Kiwi, Organic Lycium (Goji), Organic Amla.
