Vitamin C and Glutathione: interaction, severity and spacing

Vitamin C and Glutathione work better together because vitamin C helps maintain glutathione in its reduced form and spares it during oxidative stress; oral glutathione absorption is also improved by vitamin C. Take them together rather than separately. This is a synergy, not a conflict.
