migraine after b12 injection I've had a since Sept 4th. I took a that day (prescribed by my doctor) so I'm wondering if it's related or coincidence. I'm scared to take another one Too Much B12 Symptoms: Overdose

They are for patients with dual deficiencies, combining Vitamin B12 with other nutrients

The honest answer is that it depends, and it depends most on whether you are actually deficient

Intravenous (IV) use is less common and only done in clinical settings

If you have any questions, consult your doctor or pharmacist

However, make sure to not exceed the dosage range of 500mcg to 600mcg per day because you might risk experiencing adverse effects

The only thing I can say is that my mum and nan both have anaemia, but I think its my ferritin levels that are low (theyre at 9) and thats why I have to take 3 iron tablets a day
