What variations of vitamin C exist?

Spotting a good one on the shelf

Look for

  • Look for 'Buffered ascorbate' on the label (the gentle one)

Watch out for

  • Chewables, gummies, or drink powders with added sugar
  • Big servings that cause loose stools or gas, a sign it's more than your gut can absorb

Check with your provider first if…

  • You've had kidney stones, especially oxalate stones (the most common kind)
  • You have hemochromatosis or another iron overload, since vitamin C helps you absorb more iron
  • You have kidney disease
  • You have G6PD deficiency (an inherited red blood cell condition), especially before high-dose or IV vitamin C
  • You're in cancer treatment. Check with your oncology team first.
