How to take it

Vitamin C

Updated: October 25, 2026

Vitamin C is an antioxidant needed for immunity and collagen, and it improves iron absorption.

  • 200–500 mg a day with food is enough.
  • Stay below 2000 mg — stomach upset and kidney-stone risk.
  • Taking it regularly may shorten a cold slightly, but it doesn't prevent colds.

Best food sources: peppers, kiwi, citrus, cabbage.
