Can You Take Glutathione Peroxidase and Vitamin C Together?

Use extra care with this pair

The short answer

Glutathione Peroxidase is an antioxidant enzyme that reduces peroxides, while Vitamin C also scavenges free radicals. Excessive stacking of antioxidant defenses may blunt beneficial reactive oxygen species signaling, particularly during exercise.

How to arrange timing

When combining Glutathione Peroxidase with high-dose Vitamin C, consider timing around exercise — avoid taking both immediately before workouts.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
