Vitamin C and exercise/training

According to several sites online, vitamin C supplements doesn't get a long to well with training, having negative impact on the mitochondria in the muscle cells. Since mitochondria are the "power plants" of the cells, researchers argue that vitamin-C lowers endurance capacity.

Give me your thoughts!

Yes, this is true, it's best to avoid taking vitamin C just before or after workouts. I try to take vitamin C only first thing in the morning or at night, depending on circumstances.

Vitamin C is a water-soluble vitamin, Vitamin C is one of many antioxidants and Vitamin C helps your immune system. It helps you heal from scrapes and bruises.
Serious side effects from too much vitamin C are very rare, because the body cannot store the vitamin so kindly take care before taking the vitamins.

I've already heard about it, but to be honest i havent noticed any change since i stopped drinking it with water all the time (prior and post exercises). I used to drink it mixed (about 200g) in water prior working out, but noticed nothing negative.

It does any harm in the body, or just slows mitochondria and by that metabolism?

Interesting, tnx.

i think vitamin C is good to lower cortisol... so i would never workout without taking it...

The study seems to say that it's detrimental when taken on a daily basis, not before or after exercise?

The rats in the study were hampered (a lot it seems, something like 180% to only 25%) in their progress when taking daily vitamin C...

Very weird, I thought vitamin C was good overall.

yes,
vitamin C is good essential for building collagen and lowers high cholesterol.

There was a thread about this before:

FWIW, ROS (reactive oxidative species) do have several physiological functions in your body:
(1) As discussed in the above thread, they are involved in the development of muscle tissue after weight-training.
(2) More importantly, cells of your immune system generate free radicals to destroy pathogenic viruses/bacteria as well as scarier things like cancer cells. I've seen cell culture studies showing that sufficient concentrations of NAC inhibit the ability of white blood cells to destroy cancerous cells.

I'm confused, what is the conclusion to this? Take daily vit c just away from times of exercise?

Vitamin C just seems to have way too many benefits to forgo entirely though. What CS said seems to be good. Just don't take it in the recovery or workout period.

here is an interesting article which talks some more about:
