Although vitamin C has relatively low toxicity, high doses of it can cause gastrointestinal disturbances, including diarrhea, cramps, nausea, and vomiting
This includes confirmed low serum vitamin B12 levels, pernicious anaemia, malabsorption states such as coeliac disease, inflammatory bowel disease, or post-gastric or bariatric surgery, unexplained anaemia, neuropathy or neurological symptoms consistent with vitamin B12 deficiency, a long-term vegan diet with symptoms or low levels, or failure of oral vitamin B12 supplementation
