Wow, thank you for all your research!
Cool dark and dry sounds like my basement, as long as I put everything in mylar.
Do you see any advantage to getting rid of oxygen?
Question.
Does vacuum sealing work the same as oxygen absorbers?
I have the vacuum sealer attachment for my food saver and use it. I always wondered how it compared to other ways of removing oxygen from items. I use canning jars for my vacuum sealed dry goods.
No, I think pills and the stuff inside capsules are so dry and inert that just keeping them dry, cool and away from UV rays(dark) wold be about as good as one could do.
