#1 Vitamin B12 (cyanocobalamin)
Deficiency correction
La frase más fuerte que podemos publicar: “Thiamine deficiency is a recognised, treatable cause of neurological disease in cats; thiamine HCl injection is an approved human drug (ANDA 080571).”
Evidencia y limitaciones
Thiamine deficiency is a recognised cause of encephalopathy in cats and is treated by repletion; this is textbook clinical practice rather than trial evidence. The previously cited review (PMID 30139320) is a DIAGNOSTIC review of recurrent feline seizures and is not a source for thiamine therapy — it has been removed rather than restated. FDA ANDAs exist for thiamine HCl injection (e.g. ANDA 080571).

- The same trial found oral non-inferior to injection — at 90 days the oral arm's median was higher (1244 vs 877 ng/L). The best evidence for B12 undercuts the case for an injectable.
- Deficiency-correction indication requiring a serum cobalamin assay. Not a wellness product.
- GFI #256 distribution bar applies.
