Some oils, like krill oil, shouldn't be refrigerated (in general) because of the gelatin capsule--they will leak as they contract.

It's not a bad idea to refrigerate most medications, but again, if you take them pretty quickly (within 2 months or so), it's not necessary. You'll take them before they can degrade. Unless your house is really humid and moist, like my former neighbor who had lots of plants and put cellophane over her windows. Anyone could see from outside that her house was just like a greenhouse.

I just don't want anyone to think that they have to carry an icepack for their routine meds and supplements when they travel! Just don't keep them in a hot car where they would melt. And that's the reason I never put my supplements in my checked luggage.
