What are the symptoms of excessive B12
Use of vitamin B 12 in patients with elevated serum homocysteine levels and cardiovascular disease does not reduce the risk of myocardial infarction or stroke, or alter cognitive decline
Rarely reported symptoms associated with excessive B12 intake may include: Skin reactions : Acne-like eruptions or rosacea-type dermatitis have been occasionally reported, particularly with high-dose intramuscular injections Gastrointestinal disturbance : Mild nausea, diarrhoea, or abdominal discomfort, though these are uncommon Headache : Infrequent reports of headaches following parenteral B12 administration Hypersensitivity reactions : In very rare cases, allergic reactions to injectable B12 preparations have been documented It is crucial to note that there is no established link between standard B12 supplementation and serious adverse effects
Storage and handling: protecting your doses Correct dosing means nothing if the medication in your vial has degraded
