Keep a close eye on how youre doing
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
While more studies, especially on humans, are still underway, the existing evidence suggests it could potentially speed recovery from injuries both minor and severe
So, injections are a more direct way to make sure your body gets the B12 it needs, while tablets might not work as efficiently because they have to go through your stomach and intestines first
