Poten-Cee + ZN Advance Adverse Reactions

Vitamin C: Vitamin C toxicity is very rare, because the body cannot store the vitamin and immediately excretes it in urine. However, if patient takes amounts greater than 2,000 mg/day the patient may experience stomach upset and diarrhea. The daily use of high doses may lead to the formation of oxalate stones in the kidneys. Patient may also experience disturbed water and electrolyte balance in the body, increased hemolysis (breaking-up of red blood cells), increased calcium in the kidneys and suppression of cobalamin (Vitamin B₁₂) activity. If a patient has a condition called glucose-6-phosphate dehydrogenase (G₆PD) deficiency, taking too much Vitamin C can cause hemolysis which may cause the patient to feel tired, or dizzy, or even cause a patient to be anemic. In some rare cases, patient may experience painful urination or pink/bloody urine. If any of these effects persist, tell the doctor immediately. For women who take high doses of Vitamin C during pregnancy, babies may develop "rebound scurvy" after birth and require immediate Vitamin C supplementation.
