What are Mineral Ascorbates (Vitamin C)?

[elsa]

Vitamin C, also known as ascorbic acid or ascorbate, plays two important roles in the body. First, it is a cofactor or cosubstrate for eight enzyme systems involved in various functions, including collagen synthesis, ATP synthesis in mitochondria, and hormone biosynthesis. Second, vitamin C is a potent water-soluble antioxidant with a vital role in protecting cells and tissues from damaging oxidizing agents, including superoxides, hydroxyl radicals, and other oxygen free radical species. All of these functions derive from one fundamental property: vitamin C is a powerful reducing agent (electron donor) capable of neutralizing reactive oxidants.
Related functions performed by vitamin C include the following: it assists in the regeneration of vitamin E, and thus prolongs the activity of that fat-soluble antioxidant; it promotes iron absorption in the intestines by keeping iron in its reduced form; and, it is thought to play roles in regulating DNA transcription and protein synthesis.

The richest dietary sources include cantaloupe, grapefruit, honeydew, kiwi, mango, oranges and other citrus fruits, strawberries, and watermelon. The richest vegetable sources include asparagus, broccoli, brussels sprouts, dark green leafy vegetables, and peppers.

Although vitamin C is generally non-toxic, very high dosages (generally several grams) may cause or contribute to gastrointestinal distress and diarrhea.
