can b12 injections cause migraines I've had a migraine since Sept 4th. I took a injection that day (prescribed by my doctor) so I'm wondering if it's related or coincidence. I'm scared to take another one Headaches & long COVID –

Sikiric et al., 2013

B12 does not accelerate weight loss or type 2 diabetes management in patients taking semaglutide

For suspected macro-B12, precipitation with PEG is the test most often reached for, though it is nonspecific and can remove B12 that is fully available to cells, so direct measurement of the binding proteins, haptocorrin and transcobalamin, may be more informative when it is available

Some early work reported favorable effects on fat metabolism, while larger later trials did not produce the weight loss outcomes needed for approval

Always inject close to the affected area for maximum benefit

If we are lucky and our mother had a good supply of B12, we would be born with a store, but this eventually runs out or stops being accessible for many reasons
