1. What Does the Research Say

Exercise creates oxidative stress as muscles break down and adapt to become stronger. While vitamin C has antioxidant properties, taking too much can block the oxidative stress signals necessary for muscle repair and adaptation.

2. Bio-individuality

The amount of vitamin C you can take without disrupting the repair process depends on your level of oxidative stress. For most people, consuming more than 0.5g of vitamin C after a workout might interfere with the repair signals and hinder mitochondrial biogenesis.
