There has been evidence that those with minor imbalance of blood cells [for unspecified condition], in which the red blood cells are small and less in quantity than white blood cells, can be of benefit by a dosage of Vitamin C and daily moderate exercise.
When in the case of shortness of breath, while at the same time having such small in size red blood cells, were able to show benefit by a dosage or iron and Vitamin C in a single dose. (this was not a contraindication of the particular case)
Can you verify that cases of unspecified shortness of breath that may be correlated to small-sized red blood cells, can benefit from a monitored vitamin dosage?
Similarly, Co-Q10 shows benefit for those who may have heart damage. Of course, a doctor must manage patient supplements.
