Iu-International units. Am not sure about ug may be micro grams.

IU is short for "international units." IU stands for International Units and is used for the measurement of drugs and vitamins.

Webster's defines IU as: a quantity of a biologic (such as a vitamin) that produces a particular biological effect agreed upon as an international standard

What this means is that IU is dependent on the potency of the substance, and each substance would have a different IU to milligram conversion. For example, 1000 IU of Vitamin C would have a different weight than 1000 IU of Vitamin A

ug is another way of saying 'micrograms.'
