Refrigerating Supplements

I was wondering what supplements, AFTER OPENING, would stay fresher in a refrigerated environment as opposed to just sitting out on the shelf. I’d rather not keep everything in the fridge because that would be cumbersome and probably pointless for some stuff.

Fish oil, flax oils, maybe anything in a gel cap would be suited better kept in this kind of environment? What do you guys think? Have any insight?

Sure fish oil and such other than that I wouldnt sweat it to much unless you’ll be using the supp very slow. Also the freezer is a better choice for say powders etc as there is no moisture.
