Some feel placing DCA in a freezer is important, most seem to feel just refrigeration is fine. It is claimed the freezer keeps DCA fresher for much longer, but from a practical point of view, you will go through a 100 g bottle rapidly enough that it does not matter. We keep it in the refrigerator. We do not worry about with or between meals. Benfotiamine is taken in the morning around the time DCA is taken. Might be taken at the same time or at a different time, same with thiamine at night.
