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?
Very interesting. I think this "I’m sure that there are further insights (and corrections) that can be extracted from the literature in place today, and I look forward to seeing that literature itself become half-obsolete next year." says it all though. For the time being I will stick to vitamin D and magnesium as my only supplements.
The problem with vitamin C at night is that ....well that is exactly when you are fasting. If you wanted to time it, it would seem taking it with your meals only is your best bet.
Yeah, this is pretty well known in the exercise community. Antioxidents blunt the hormetic stressor that exercise provides so you actually don't get the benefits from the exercise. Even ibuprofin PWO will limit the benefit you get from the workout.
