  • He concluded that the optimal daily intake of vitamin C for most people is 2.3 grams to 10 grams daily.
  • A Study published by Amanda Bucher and Nicole White in 2016 shows a decreased severity and duration of colds when vitamin C is consumed at doses at or above 0.2 g/day
  • Vitamin C is not produced endogenously in humans and is therefore an essential dietary component.
