FOR SURE in a supp form and or yoghurt. Her body just doesnt know how to digest real damn food any more. Its used to CRAP that has been bombarded, processed, zapped , predetroyed, leeched and digested for her.
Kind of like someone new to training jumping in HARD CORE. They get sore as shit. Thier body, Her digestive system aint used to working. It needs time to adjust. Good thing is in time she will be eating more and losing do the the expendature that digestion of REAL food and the k/cal cost it has as opposed to that processed crap.
Best of luck,
