A more evidence-based way to evaluate whether something is helping is to track measurable outcomes with your clinician (for example, symptoms tied to confirmed deficiency, or objective metrics like body weight, waist measurements, and lab work when appropriate)
It is intended for use in clinical settings where oral administration is not feasible or where higher plasma concentrations are desired, such as in cases of severe deficiency, certain infections, or as adjunctive therapy in specific medical protocols
Its absolutely critical to remember that B12 injections are a Prescription-Only Medicine (POM) in the UK
Concentration is held constant across every vial size so your unit count never changes
Vitamin B12 can do all sorts of good things for older folks
Vitamin injections are generally considered to be very safe, they have no major side effects and zero down time
