More on the subject of Vitamin C uptake by macrophages under attack. I
think more precise results can be obtained by using the most available
location of macrophages, in the skin. A test might proceed as follows:
1. Have subject take a dose of 1000 mg of Vitamin C,
2. Wait two hours to be sure a good level in blood is established,
3. Apply some substance or action to an area of skin which will provoke
an immune system reaction, perhaps cigarette tar,
4. Wait 30 minutes for reaction,
5. Remove substance and take scraping of skin,
6. Also take quick scraping of an area of untested skin,
7. Analyze both samples for both ascorbic acid and dehydroascorbic acid,
8. Compare results.
This assumes macrophages work pretty much the same everywhere.
