Dr. Cathcart has successfully treated over 20,000 patients with very large doses of vitamin C, sometimes administering over 150,000 mg per day. A short biography of Dr. Cathcart is posted at http://orthomolecular.org/hof/2008/cathcart.html .
Years ago there was some testing on “internal” vitamin C creation in goats.
You do know that most animals on the planet actually don’t need vitamin C, because they make their own?
Humans (and all great apes) lack one of the genes (out of three) to make their own vitamin C.
Anyways, they took some goats and put them on a shock pad where a few times a day they were given a jolt.
After a few days, these goats (whose normal production of Vitamin C was in the 6,000-10,000 mg range SKYROCKETED to about 100,000 milligrams per day!
Tells you something about goats, eh?
Fauci would probably say it doesn’t mean anything for humans at all...
