I have always wondered about the adage, “It’s not what you eat, it's what you digest.”   What does that really mean?  And, how is your food transformed into the nourishment required for every cell? 

Extracting the essential nutrients from food is the job of your digestive enzymes.  Optimal health, abundant energy, strong immunity and cellular vitality are dependent on a full spectrum of digestive enzymes.  And, therein, lies the problem!
