However when vitamin C is given as an intravenous infusion we create a shortcut to our bloodstream. As mentioned, a reabsorptive mechanism controls vitamin C concentrations, but it also depends on the amount absorbed by our intestines and the accumulation in our tissues. When daily ingestion exceeds 200mg, all three mechanisms act to keep levels low, this explains why the more is consumed, the more is expelled from our system. Once again, the pathway makes the difference.
When you receive an infusion of vitamin C you obtain a high dose in the order of grams, not mg. Because there is not a tight concentration control you can fully benefit from its healing properties.
The amount we can store varies greatly between tissues. The highest concentrations have been detected on the pituitary and adrenal gland, still, it accumulates in almost every cell, tissue and organ such as the brain, eyes, lungs, muscles and even on saliva! It has also been noted that the amount we can absorb decreases with age. Ascorbic acid or vitamin C has been called an enzyme cofactor, meaning is essential to their function, but not only that; for example, it also assists on the biosynthesis of dopamine -the neurotransmitter that regulates movement and emotion-, as well as in the regulation of collagen. What’s more, it acts as an antioxidant reducing free radicals.
