Vitamina C - Side Effects

Nombres alternativos

Ácido ascórbico; Ácido deshidroascórbico

Efectos secundarios:

Los efectos secundarios serios a causa de demasiada vitamina C son muy infrecuentes porque el cuerpo no puede almacenar dicha vitamina. Sin embargo, no se recomiendan cantidades superiores a 2,000 mg/día, dado que tales dosis altas pueden llevar a malestar estomacal y diarrea.

Muy poca cantidad de vitamina C puede llevar a signos y síntomas de deficiencia, como:

Anemia.
Encías sangrantes.
Disminución de la capacidad para combatir infecciones.
Disminución de la tasa de cicatrización de heridas.
Resequedad y formación de mechones separados en el cabello.
Tendencia a la formación de hematomas.
Gingivitis (inflamación de las encías).
Sangrados nasales.
Posible aumento de peso debido al metabolismo lento.
Piel áspera, reseca y descamativa.
Dolor e inflamación de las articulaciones.
Debilitamiento del esmalte de los dientes.

Una forma grave de deficiencia de vitamina C se conoce como escorbuto, que afecta principalmente a adultos mayores y desnutridos.
