You know, sailors used to get scurvy because of C deficiency back a couple centuries ago. Vitamin C degrades really easily, but is there any way you can store it long term other than pills or tablets? I’m just wondering if it would have been possible to do this in the past with the technology that was available.
Here’s a really interesting article on how it was discovered that citrus would help. They were also able to preserve citrus and citrus juice with alcohol. They could also turn it into a concentrated syrup without too much loss of vitamin C.
From what I just read, they didn’t do this, but dried citrus, when dried at a cool temperature, retains the majority of its vitamin C.

Jam is the classic way to preserve fruit.
