Óxido Nitroso
  • Vitamina B12 y Folato - Complementación Posiblemente Útil
English Version

El gas de óxido nitroso se usa principalmente como un anestésico local en la odontología, así como en ciertas fases de la cirugía de bypass cardíaco.

Complementación Posiblemente Útil
De vez en cuando, el óxido nitroso puede provocar deficiencia significativa de vitamina B 12 , especialmente en personas que ya están al borde de la deficiencia de dicha vitamina (por ejemplo, los vegetarianos al 100%) o quienes con frecuencia están expuestos al gas, como los dentistas y anestesiólogos. 1–4

El efecto sobre la B 12 también impacta al folato. 5, 6, 7

Tomar suplementos de folato y B 12 de acuerdo a los niveles de U.S. Dietary Reference Intake (conocido anteriormente como la Recommended Dietary Allowance) debe prevenir el desarrollo de cualquier problema.
