La ausencia de datos de eventos adversos no debe leerse como evidencia de seguridad
NICE Clinical Knowledge Summaries recommend B12 injections for: Pernicious anaemia an autoimmune condition affecting intrinsic factor production Malabsorption syndromes including coeliac disease and inflammatory bowel disease Post-surgical states particularly following gastrectomy or ileal resection Strict vegan diets when oral supplementation proves inadequate, though oral cyanocobalamin is usually sufficient for dietary deficiency Clinical trials demonstrate that B12 injections rapidly improve haematological parameters and neurological symptoms when deficiency is confirmed through blood tests
The peptide reconstitution guide covers the lyophilized workflow for researchers who also work with the injectable format
However: Broad energy, immune, or anti-aging claims are not universally supported by high-level clinical evidence
If you are deficient, and are looking for a simple solution to cure that deficiency, for a reasonable price, look no further than vitamin B12 drops
