Recent studies have linked Vitamin B12 supplementation to increased cancer recurrence and mortality

Unlike class A GPCRs (such as beta-adrenergic, opioid, and histamine receptors), which have been successfully targeted by small molecules for decades, class B GPCRs possess a large N-terminal extracellular domain (ECD) of approximately 120-160 amino acids that plays a critical role in ligand recognition and receptor activation

The study also documented increased skin density and thickness, indicating structural improvements beyond surface-level changes

Thats why a UK petition is urging the House of Commons to request the government to declassify injectable B12 as Prescription Only Medicine
