As the sodium salt of ascorbic acid, it is known as a mineral ascorbate. It has not been demonstrated to be more bioavailable than any other form of vitamin C supplement. [2] Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium).
Ascorbic acid efflux by embryos of dicot plants is a well-established mechanism of iron reduction and a step obligatory for iron uptake. [a] All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant and regenerator of other antioxidants. [95]
Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative. [citation needed] In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photobleaching. [14]
An example of a mineral ascorbate drug is sodium ascorbate injections (the acid form, ascorbic acid, of vitamin c is too acidic for injections). Ascorbate salts may be better tolerated by the human body than the corresponding weakly acidic ascorbic acid. Ascorbates are highly reactive antioxidants used as food preservatives. [2]

However, the NHS recommends 10μg of Vitamin D per day throughout the pregnancy and while breastfeeding, and 400μg of folic acid during the first trimester (first 12 weeks of pregnancy). [15] Some women may need to take iron, vitamin C, or calcium supplements during pregnancy, but only on the advice of a doctor.
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbic acid) in doses well beyond the current United States Recommended Dietary Allowance of 90 milligrams per day, and often well beyond the tolerable upper intake level of 2,000 milligrams per day. [1]
Potassium ascorbate is a compound with formula KC 6 H 7 O 6.It is the potassium salt of ascorbic acid and a mineral ascorbate.As a food additive, it has E number E303, INS number 303.
