Multivitamin for Pre-Op and Post-Op Liquid Diet

Research studies have shown people with obesity can be prone to vitamin deficiencies.1 Additionally, bariatric patients face, vitamin deficiencies which are common from the restrictive post-surgery diet.2

Before weight loss surgery, patients are required to go on a liquid diet in order to prepare their body for the surgery. The liquid diet can last anywhere from 7-14 days and aims to reduce the fat located around the liver and spleen. It is crucial for bariatric patients to follow their surgeon’s liquid diet plan correctly.

Similarly, after the bariatric procedure, patients must follow a strict diet to maintain the rapid weight loss that accompanies the surgery. For certain procedures that restrict the size of the stomach not as much food, and therefore nutrients, can be consumed. The BariComplete multivitamin powder and BariSunny chewable vitamin D are designed to be a part of the pre- and post-op diet to prevent vitamin deficiencies that can be taken with the BariEssential protein meal replacement.*

*Always talk to your physician before using any supplements after surgery.
