Ascorbic Acid is a known antioxidant molecule and its stability has always been an issue especially for pharma industry which often makes use of AA in formulation. Now as much as pH is a culprit in AA degradation, its only one among other factors like solvent, exposure to light/uv, and the nature of solution (viscous/non-viscous).

The daily intake of ascorbic acid must equal the amount that is excreted or destroyed by oxidation. Healthy adult human subjects lose 3 to 4% of their body store daily. To maintain a body store of 1500 mg of ascorbic acid or more in an adult man, it would thus be necessary to absorb approximately 60 mg daily.
