Thanks to Grant Genereux, a new perspective of the first scurvy problem revealed itself.

Quote from Grant: “Therefore, some of the mainstays of the ship’s provisions were heavily salted beef and pork, oats, beer, very dry biscuits, and something called “portable soup”.”
Quote from Grant: The “portable soup” consisted of “all the offals of oxen killed in London for use of the Navy” with salt and vegetables added in.
Offals = “internal organs and entrails“… aka a lot of Vitamin A.
So vitamin C is still good, but it wasn’t the full story. High doses of vitamin C may slow ALDH a process for detoxing vitamin A.
Other cases of prisoners fed a diet of only rice for a year or more, with no vitamin C, never developed scurvy.
Humans use and reuse the oxidized form of vitamin C (dehydroascorbic acid). so we actually don’t require much in the diet.
When I was eating a lot of bacon and eggs, I would get bleeding gums. I took vitamin C, it got better, but the underlying problem was there, too much poison vitamin A in the diet.
Take it for what my opinion is worth. This is what makes the most sense to me.
