As we know, exercise increases insulin sensitivity. This study says vitamin C and antioxidants negate that effect.
Apparently it shuts down the benefits of autophagy too. http://metamodern.com/2010/09/26/antioxidants-block-cell-repair/
So does this mean we should not take Vit C?
Or should we time intake appropriately? The study doesn't mention timing. I wonder if taking Vit C at night, long after exercise, and not during the autophagy phase of a fast, would help?
