PMID 18566306

What should we do in clinical practice

B12 injections tend to be most useful for: Patients on GLP-1 medications (semaglutide, tirzepatide) who feel fatigue in early weeks Patients with low energy, brain fog, or mood symptoms Vegetarians or vegans (plant foods don't contain B12) Adults over 50 (B12 absorption drops with age) Patients who've had digestive surgeries (bariatric, gallbladder) that affect absorption They're generally safe B12 is water-soluble, so your body excretes what it doesn't use

Taking vitamin B12 may cause contact dermatitis if you have a severe allergy

Patients must strictly follow the doctor's instructions, not self-adjust the dosage, and should not stop the medication without the doctor's approval 5
