Does a fan cool objects? I have a ceiling fan in my office which really helps to keeps the room cool. Does it also cool down vitamins in a plastic bottle with a screw on top? My office can get very hot which is probably not good for them. I keep them in my office to remember to take them. :-) I leave the fan going to keep them cool but my husband swears it does not change the temperature for them.

A fan can keep a person cool by two methods: (1) increasing the rate of evaporation of sweat off the skin, and (2) moving air warmed by the person's body away from their skin. See this answer for more details. A bottle of vitamins does not sweat nor maintain homeostasis, so blowing air on it does not affect its temperature.
The plastic bottle is a decent insulator, so the vitamins will stay near a temperature between the hottest room temperature (during the day) and the coldest (at night). Putting them in a drawer will further reduce the changes in temperature.
