Good luck with that- in my experience,most carriers do not pay for any type of "medical food" just as they would not pay of regular food. Also, with so many protien shake options out there it's not necessary to limit yourself to one supplier. The protien shake phase isn't easy, and taste counts! Not all shakes are equal- one with low carb and low sugar is a necessity. I hope you find something that works! My MD ofc was really into selling thier brand- I tried it and found that GNC Slimshake was comparable nutrient wise, and a little better in price and flavor. Same with the vitamens. WLS is an industry- and when it's time to get your supplies it's important to remember that even your MD's ofc is looking to make money.
