title_body: Which vitamins & minerals does coffee provide?
upvoted_answer: Here are some nutritional information for brewed coffee that list macro- and micro-nutrients such as those you list:
  
  
  from CoffeeAndHealth
  from Self
  the Google search page includes nutrition information from USDA.
  
  
  Looks like there are traces of various B vitamins, a fair amount of riboflavin (B2), and traces of minerals such as magnesium, phosphorous, and potassium. 
  
  All of this nutrition data will certainly depend on the origin, roast, preparation methods, and other factors, which affect what gets into the cup from the beans.  Unless you're eating the beans...
