I subscribed to the Chef V Green Drink weekly delivery for 3 months consistently. Initially, I committed in hopes of getting more vitamins/nutrients I knew I was lacking in my diet. I also have diverticulosis, a condition in which small pouches develop within the large intestine and can be very painful. I was having gas pain daily and after just 1 month of daily green drinks, that pain went away! I do believe this green drink helped flush out my colon to give it a fresh start.
