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.
Preserving has been an option for much of our history and it works much better than just storage.
Edit: to be fair, both storing and preserving basically just mean keeping. I’m talking more specifically about dehydrating, pickling, fermenting, and candying.
