(NaturalNews) Chronic obstructive pulmonary disease, or COPD, is a rather vague name for a chronic disorder that inhibits breathing and oxygen delivery to the blood. It manifests in decreased lung capacity from various reasons and inhibits breathing. It can get progressively worse, leading to chronic bronchitis or emphysema.

Recently, a study involving IV-infused ascorbate vitamin C (ascorbic acid) in COPD sufferers was performed to observe how vitamin C affects COPD sufferers’ exercise performance and fatigue levels.
The study involved ten COPD sufferers who were familiarized with specific knee extension exercises to create skeletal muscle fatigue and demand more oxygen into the blood. Several test parameters were established to determine oxidative stress, fatigue, breathing capacity and other factors that exist with COPD. (1)
Because of the limited number of subjects, all the subjects were randomly given placebo saline solutions alternated with ascorbate C in saline solutions. Neither the subjects nor the researchers knew what was going through the IV catheters attached to the subjects’ arms at any given time. Only whoever was making the solutions knew.
The actual ascorbate C solutions contained only 100 mg of ascorbic acid and were administered with an infusion rate of 1 ml per minute for 20 minutes. This is not a mega-dose IV C blood level, not even close. But it was a proper measuring effort for testing with a predetermined constant blood level of ascorbate C, since absorption of oral C into the blood varies among individuals.
It would take several hundred milligrams more of oral vitamin C with ascorbic acid to render that 100 mg of blood level vitamin C, and that exact amount would vary from one person to another.
So this trial was apparently concerned with observing what effect normal oral supplementation with ascorbate C or ascorbic acid could have on COPD sufferers’ antioxidant activity, muscular fatigue and breathing capacity.
