Metallic taste in mouth
The symptoms of ketosis don't usually crop up only during a specific activity, the bad breath is typically constant, though I suppose it might be more noticeable right after eating or drinking something. It's possible that the calcium supplements themselves cause a souring that tastes metallic in the mouth or that its a symptom of a mild allergy to something in the supplement - those are most likely. Oddly enough it can also be sign of both too little or too much calcium in the blood, but again, that would be constant - so its kind of a crap shoot without other symptoms to match it up with.
