All good advice but if you can travel with the original labels for Vitamins especially clear gel type like Fish Oil then all the better.
Some countries like Dubai and even Australia have some very interesting rules as to the drug content itself especially for over the counter items from Western countries.
Most countries have no issues with tourists traveling through with a supply under three months and of course if you are cruising the supply is in your cabin.
So,we are really talking about airport security, immigration checkpoints.
For prescriptions meds get your pharmacist to print out labels .
As a Canadian I can get weird reaction out of the Homeland Security folks if I travel with items that look like or smell like vs. a valid labeled container.
