You may notice slightly less bloating and a feeling of metabolic "lightness" after meals

A Vitamin B12 injection can help to improve your energy levels, helping you to feel more wide awake, switched on and energised

As I elaborate on in my video The Symptoms of Vitamin B12 Deficiency , these include: Abdominal distention Chronic diarrhea Shortness of breath Swollen, red, painful feet Skin darkening Bilateral useless hand syndrome Numbness and tingling in the hands and feet Muscle cramps Dizziness Cognitive disturbances Difficulty walking Erectile dysfunction Fatigue Depression Psychosis Coma Blindness Vitamin B12 Deficiency Treatment Is A Vitamin B12 Shot Better Than Taking B12 Orally

Results vary and depend on diet, exercise, and individual metabolic factors
