¿Qué tipo de B12 es mejor: cianocobalamina, methylcobalamina o hidroxocobalamina?

Llevo años siguiéndote y comprando tus DVD. Te conocí en Ann Arbor en una cooperativa de alimentos. ¿Es cierto que la cianocobalamina (que es lo que tú recomiendas para los veganos) se convierte en cianuro y que es mejor tomar hidroxicobalamina? Al menos según la página web de Raymond Francis, un científico del MIT. Lo que decía era que la cianocobalamina no es natural, ha sido creada por el hombre, y el cuerpo no la utiliza bien. Que lo que sí se absorbe se convierte en cianuro. ¿Podrías ayudar con esto?

A ver si adivino… ¿esta persona no venderá suplementos de hidroxicobalamina, por casualidad?

Es como el escándalo del calcio de coral. El calcio es tan barato como la tiza; de hecho, ¡es tiza! ¿Cómo vas a ganar mucho dinero con eso? Pues vendiendo un calcio especial. Es lo mismo con los suplementos de vitamina B12.

Los suplementos de B12 son tan baratos de producir que parece que las empresas de suplementos quieren encontrar versiones más elegantes para añadirle valor a sus productos y poder cobrarte 30 dólares por bote. A menos que seas fumador, padezcas de fallo renal, o que lo único que comas sea yuca, no tendrás problemas con la cianocobalamina. ¡Es lo que pienso!
