These injections are gaining attention because some users report noticeable weight loss results when they use semaglutide with B12
B12 vitamin shots may cause pain at the injection site, mild diarrhea, and swelling
Doctors often talk about the dosage in mL, not just the vitamin B12 amount in micrograms (mcg)
When to seek medical attention: Patients should call 999 immediately for severe allergic reactions (facial swelling, breathing difficulties, widespread rash)
In that case, the best time to take vitamin B12 injections would be seven to ten days prior and again one to two days before your event
Individuals with conditions like coeliac disease or Crohns disease, which can limit B12 absorption from food, may particularly benefit from B12 injections
