Exjade works better when taken with food. Now, here in the forum, members reported with experience (long before Norvatis reported) that they feel less/or no symptoms of nausea, vomiting or abdominal pain when exjade is taken with food. As JV mentioned, Norvatis came with the same conclusion. The label change is an expense issue for them. Do not get confused.
Members reported different ways of taking exjade, some dissolve in water, orange juice etc. Some crush it and take with food. Now, this is an interesting scenario, isn't chewing and crushing the same thing (in a sense). If Norvatis is okay with crushing and mixing it with food, should they change the label and remove chewing part as well or it is a question of expense for them.
However, as I cannot speak to the molecular chemistry of Exjade (I would follow the instructions or any other proved conclusion).
