Not everyone takes enzymes...but if they take enzymes...more than likely they need A,D, E, K as well. It depends on how bad the pancreas is affected. When the pancreas isnt working correctly...the body does not absorb the fats that it needs. Vitamins A, D, E, K....are fat soluble vitamins so they in turn are not absorbed properly either. Hope this helps! By the way...I have taken enzymes all my life...I was diagnosed at not quite 6 weeks old...
