Answer
She shouldn't need anything except the dog food.  It is formulated to give the dog everything it needs.  If anything,the dog food is a little high in calcium.  Adding more is very bad for larger puppies such as Labs.  You may need to increase the food before long.  It is best for the dogs joints if it stays lean, but you don't want the ribs to show, see http://www.longliveyourdog.com/twoplus/RateYourDog.aspx  Many Labs eat very quickly and look for more.  Do not give her too much,

The best solution to stool eating, coprophagy, is cleaning them up before the dog has a chance. You can try food additives, the home remedies pineapple juice or canned pumpkin or the commercial products Forbid or Deter.

Why dogs do it is poorly understood. It may be diet related, but changing the dog's diet might cause worse problems. Whatever problems it causes for the owner, it doesn't seem to hurt the dog unless you are trying to clear up a worm infestation.

I think 10 hours is too long to leave her by her self.  If you can't make it back for a break, see if a neighbor or a professional dog walker can.
