Vitamin supplement storage question

[Mish]

I have a general question about how you store your fish vitamins.

I use both Selcon, and Vita Chem, and I keep both containers in the fridge. Is this a bad practice, am I destroying them by doing this? I should also mention that I mix these with a variety of frozen foods and then, re-freeze into new blocks to feed later. By doing this(freezing the vitamins) am I rendering them usless?

Thanks!

Freezing should be fine. The American Marine website (makers of Selcon) has a recipe to make fish food using fresh seafood and Selcon. The recipe tells you to freeze the food and selcon mixture into cubes for storage and convenience.
