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.
Got a spruce tree? Grab the newer green tips on the branches and check it in some hot water. That tea is full of Vit C, and tastes like Christmas smells. And the tree isn’t going to go bad.
