Most clients receive injections weekly to monthly, depending on their goals and lab results
Because injections bypass the digestive tract, they may offer different absorption characteristics than oral routes, though the clinical significance of this is still being studied
Administration and Dosage Vitamin B injections must be administered by a trained health professional (nurse, doctor) or by a patient who has been taught proper technique
Children presenting neurological signs or symptoms, those unable to take oral medication, individuals with known malabsorption syndromes, infants under 6 months old, and patients using medications that may interfere with vitamin B12 absorption are typically treated with a parenteral protocol (1)
