This is likely due to enhanced mitochondrial efficiency and improved fuel utilization in muscle cells
Chemically it is not a peptide at all, so the peptide dosing mental model only partly applies: the reconstitution math is identical, but the route options are broader (a small molecule can survive and be studied by mouth in a way most peptides cannot)
That difference medical-grade and monitored vs
Once consumed, cyanocobalamin is converted to the biologically active AdoB 12 and MeB 12
For patients seeking weight loss who request B12 injections, GPs should: Assess for genuine deficiency through appropriate blood tests rather than empirical treatment Provide education about the lack of evidence supporting B12 for weight loss in non-deficient individuals Explore underlying concerns about weight and energy levels, addressing these through appropriate channels Signpost to evidence-based resources such as NHS weight management services according to local pathways Patients should contact their GP if they experience unexplained fatigue, neurological symptoms (numbness, tingling, balance problems), or signs of anaemia (pallor, breathlessness, palpitations), as these may indicate B12 deficiency requiring investigation
