The medication is injected intramuscularly-commonly into the upper arm, gluteal muscle, or thigh
This deficiency can be caused by poor dietary consumption, a breakdown in the digestive process, or from taking certain medications that make it difficult to absorb B12 (such as antacids)
When it comes to lipotropic injections, how often they are needed is something that is determined by several factors
That is the closest thing to a default answer
Many patients have undiagnosed low b12 even before medication use, particularly among certain risk groups
Plant foods do not naturally contain active B12 some fortified foods (plant milks, nutritional yeast) and supplements can help, but injections bypass any absorption issues entirely
