The intramuscular route ensures consistent, reliable delivery of B12, independent of gastrointestinal absorption
Supports Fat Metabolism The liver has to break down fats efficiently

Bacteriostatic 0.9% Sodium Chloride Injection is not a medication on its own its a diluent or solvent used to prepare other drugs for injection. According to its labeling, this solution is indicated only for diluting or dissolving drugs for injection (whether intravenous (IV), intramuscular (IM), or subcutaneous (SC)).For example, if you have a vial of powdered medication that needs to be injected, you might add this bacteriostatic saline to reconstitute (dissolve) the powder into a liquid form for injection. Similarly, it can be used to dilute concentrated drugs to the proper strength before injecting them. Healthcare providers also sometimes use sterile saline solutions to flush IV lines or injection sites, but in many cases preservative-free saline is preferred for flushing (especially in sensitive patients). The key point is that Bacteriostatic Sodium Chloride 0.9% Injection provides a sterile salt-water medium for mixing medications, and its bacteriostatic property allows the vial to be used for multiple doses or multiple patients (with proper sterile technique) instead of being discarded after a single use

inspect for discolouration or particles (note that B12 solution is normally red) Prepare the injection site common sites include the thigh (vastus lateralis) for both IM and SC injections, or the ventrogluteal area for IM administration if trained to use this site Administration technique: Clean the injection site with an alcohol wipe and allow to dry completely
Mistake 3: Applying vitamin C serum at the same time
Thats when injections become the most effective route, delivering B12 directly into your system to bypass the problem
