Heres why: Ongoing Absorption Issues: Many people have conditions that impair their ability to absorb B12 from food or oral supplements, such as pernicious anemia or gastrointestinal disorders
Patients managing neuropathy, chronic fatigue, or nerve pain often benefit from B12 injections as part of a broader treatment plan
The timeline is gradual: better sleep and energy at 4 weeks, less bloating and improved recovery at 8 weeks, measurable body composition changes by 12 weeks
On the broader healthcare spectrum, needleless injections can influence accessibility and costs
Methionine, in the form of S-adenosylmethionine (SAM), is required for many methylation reactions, including DNA methylation
B12 injection sites for those pains are depending on severity, how long distance from distal to proximal part of limb is affected
