It stands for International Units, which is the unit of measurement for some vitamins. It is the same idea as milligrams, though they are not equivallent.
International units exist in order to account for the fact that certain preparations of the same vitamin are not bioequivalent. Regardless of the preparation 1 IU will provide the same biological activity. For instance, 1 IU Vitamin E equals the biological equivalent of about 0.667 mg d-alpha-tocopherol, or of 1 mg of dl-alpha-tocopherol acetate. Though the mass of each preparation is different, the biological activity is the same.

There isn't a better: they are types of different measures, so you couldn't even compare the two. IU's for example are used for fat soluable vitamins. mcg's are used to measure very, very tiny amounts of other vitamins. (bear in mind that vitamins are very, very powerful chemicals - you only need small amounts of some) A mcg is a microgram - that is 1/1000 of a milligram. You are probably familiar with the milligram but don't know it. Many products are labeled in both ounces and milligrams. There are about 28 mg's in an ounce.

It clearly means "in underwear", which is usually the costume one is donning whilst taking said vitamins.
