Does vitamin C lower urine pH?

Ascorbic acid (AA) has been studied in the literature regarding to its effects at lowering urinary pH in patients with recurrent urinary tract infections. Results have been controversial. While some studies refuted its acidifying effects, others showed significant reductions in urinary pH after AA supplementation.

What pH is vitamin C?

It forms a clear colorless to slightly yellow solution. It has two pKa values: 4.2 and 11.6. The pH of a 5% (w/v) solution in water is 2.2–2.5 [9].

Is vitamin C acidic or basic?

Ascorbic acid has very high acidity and may induce these gastrointestinal side effects when ingested on an empty stomach [20]. Calcium ascorbate (neutralized vitamin C) has been developed to mitigate the epigastric adverse effects due to the low pH of ascorbic acid.

Results: Fasting urinary pH did not change after 1 g (5.8 +/- 0.6 vs. 5.8 +/- 0.7) or 2 g vitamin C (5.8 +/- 0.8 vs. 5.8 +/- 0.7). A significant increase in mean urinary oxalate was observed in calcium stone-forming patients receiving either 1 g (50 +/- 16 vs.
