Whether intramuscular (IM) or intravenous (IV) B12 is "better" depends on individual needs and desired absorption rate. IM B12 is absorbed slower over a longer period.
B12 Injections vs. Infusions: Absorption Rates
The primary difference between B12 injections (IM) and infusions (IV) lies in the absorption rate.
- Intramuscular (IM) Injection: According to Dr. CJ Pabla, "An intramuscular injection is absorbed slower over a long time frame." This means the B12 is released gradually into the bloodstream.
Choosing the Right Method
The choice between IM and IV B12 depends on factors such as:
- Individual Needs: Some individuals may require a faster absorption rate, making IV the preferred option.
- Desired Duration: If a longer-lasting effect is desired, IM injections might be more suitable.
- Medical Advice: Consulting with a healthcare professional is crucial to determine the most appropriate method for individual circumstances.
