So I'm trying to make some frozen "supplement treats" for my dog and cat, basically consisting of a bit of frozen cat/dog food and fish oil, so I don't have to open a new capsule every day. I've read that fish oil over time can lower vitamin E levels so I would like to incorporate a bit of that into their treats, too, but I am getting conflicting information. Does anyone know if Vitamin E can be frozen and retain at least a portion of the nutrient content?
