Why bodybuilders need vitamin c more than a normal person?
Intense Exercise creates free radicals which cause cell-damaging resulting in oxidative stress. Intense Exercise causes elevated aerobic metabolism, which in turn increases the production of killer molecules known as free radicals.

A free radical is a molecule that’s missing at least one electron in its outermost orbit, which causes it to be negatively charged. Like most things in nature, free radicals seek to remain neutral, and in an effort to achieve this balance they bump up against healthy cells in your body and steal electrons from them.Unfortunately, the process doesn’t stop after damaging the first cell. This newly damaged molecule is now missing an electron and becomes a free radical. Each free radical that is created zaps electrons from healthy molecules to form new free radicals, thus creating a chain reaction that damages thousands of cells along its path.
Free radical damage has become more prevalent in our society as witnessed by the increase in cancer victims in recent years. Environmental pollutants like smog, cigarette smoke and car exhaust all contain free radical molecules, and as our exposure to these increase so does our chances of degenerative diseases. Worse yet, research shows that mental stress is one of the highest causes of free radicals.
The good news is that under normal conditions your body has the inherent ability to defend against free radicals by producing three substances; glutathione, catalase and superoxide dismutase. These substances are known as antioxidants, which work as free radical scavengers, seeking out free radicals and donating the electrons needed to neutralize them, thereby quenching their need to search out and destroy healthy cells. The problem occurs when free radical production exceeds the body’s ability to produce antioxidants. This can happen during intense exercise when athletes can use from 10 to 20 times the amount of oxygen than that of a sedentary person. During exercise, the conversion of fat and sugar into energy occurs through a process known as oxidation. During this process, most of the oxygen combines with hydrogen to produce water. However, about 5% of the oxygen forms free radicals. Imagine that, every time you breathe, free radicals are formed. This process of oxidation is similar to what you see when metal rusts or an apple slice turns brown from exposure to air. Once again, your body can defend against normal levels of free radicals, but if you exercise intensely, live in a polluted area, or have a stressful life, as most of you and your students do, then supplementing your diet with antioxidants may be of great value.
A well-balanced diet with plenty of fruits and vegetables is important and will help, but alone it’s just not enough. take antioxidants supplements like a multivitamin, vitamin C & E.
