Vitamina D: ¿Es Realmente Necesaria?

Vitamina D: ¿Es Realmente Necesaria?

Múltiples estudios en los últimos dos años han demostrado que con niveles bajos de vitamina D, el riesgo de sufrir consecuencias muy graves por una infección viral es alto. Con niveles sólidos de vitamina D, esos riesgos se reducen casi a cero.

Únase a la Dra. Patricia Madrigal y al Director de salud de KnoWEwell, Tom O’Bryan, DC, CCN, DACBN y fundador de El para aprender lo que dice la ciencia. Los conocimientos esenciales para la protección y la salud óptima de usted y su familia.

Los recursos basados en evidencia estarán disponibles para su descarga durante la presentación, incluida una lista de alimentos naturales que contienen vitamina D, las formas de vitamina D, la eficacia de la vitamina D en el tratamiento de diversas afecciones de salud y las advertencias de salud asociadas con la vitamina D.
