Random supplement thing I recently learned.
High doses of vitamin C will probably reduce gains for endurance athletes. Vit C is an antioxidant. Antioxidants reduce oxidative stress. Oxidative stress is caused by endurance exercise and is what causes your body to make changes to get stronger. Less stress can equal smaller gains.
Results in the studies included below were seen at 1000mg/day.
I dosed VitC hard because I was sick for too long. I also remember reading that it improved sleep - so win/win right? Maybe, but don’t keep taking it once you start training again.
