Side Effects

Serious side effects from too much vitamin C are very rare, because the body cannot store the vitamin. However, amounts greater than 2,000 mg/day are not recommended because such high doses can lead to stomach upset and diarrhea.

Too little vitamin C can lead to signs and symptoms of deficiency, including:

  • Anemia
  • Bleeding gums
  • Decreased ability to fight infection
  • Decreased wound-healing rate
  • Dry and splitting hair
  • Easy bruising
  • Gingivitis (inflammation of the gums)
  • Nosebleeds
  • Possible weight gain because of slowed metabolism
  • Rough, dry, scaly skin
  • Swollen and painful joints
  • Weakened tooth enamel

A severe form of vitamin C deficiency is known as scurvy, which mainly affects older, malnourished adults.
