Elemental Diet for SIBO 
mixing an elemental diet shake for sibo

Using an elemental diet for SIBO is one of the most effective treatment methods. It can starve off bacteria in only 2 weeks. For some SIBO sufferers, the elemental diet is an amazing solution after other treatments have failed. This does not mean that it is without its challenges! Going without food for 2 weeks can be tough for some people alongside the side effects usually experienced at the beginning.

I designed this guide to help you learn about the elemental diet and to use it to help manage your digestive condition. The elemental formula can be such an awesome treatment if you use it correctly, have the right mindset, and are prepared for the challenges going into it. I also broke down all the different product options available so that you can save time and money!


What is an Elemental Diet and How Does It Treat SIBO?

The elemental diet is a medical food consisting of pre-digested powdered nutrients in an easily absorbed form. It contains all of the nutrients humans require broken down into their simplest form so that they are absorbed higher up in the small intestine. In the case of SIBO, by drinking only elemental liquid it works to starve off the overgrowth of bacteria and allows the gut to rest.

There are several components that make up an elemental formula:

  • Proteins which are broken down into amino acids
  • Carbohydrates as glucose or maltodextrin                                                                        astronaut drinking elemental formula
  • Fat as different oils
  • Essential vitamins & minerals

NOTE: There should not be any fiber, full proteins, or complex carbohydrates in an elemental diet.

The SIBO elemental diet works by feeding the person but starving the overgrowth of bacteria in the small intestine. The researched protocol for SIBO is for 14 days using the elemental formula in place of regular food. It is proven to be one of the most effective treatment options with an 80-84% success rate. Patients usually do a repeat breath test after the protocol to measure the changes from the lactulose breath test.

Fun Fact: Elemental shakes were first developed by NASA when they wondered how to feed astronauts on long space journeys. Other researchers considered the elemental formula for food allergies, malabsorption, and other digestive tract malfunctions.


 What is The Difference Between Elemental & Semi-Elemental Diet?

elemental diet vs semi elemental

A lot of times people get confused about the difference between an elemental and semi-elemental diet. The elemental diet is used specifically as a medical food as the sole source of nutrition. The semi-elemental diet is used as a supplemental product along with whole foods.

The main difference between the two is that a full elemental diet contains each nutrient broken down into it’s smallest form, while the semi-elemental diet can contain whole proteins, fiber, or complex carbohydrates in conjunction with broken down nutrients.

It is important to remember that if you are using an elemental diet to treat SIBO it must be a full elemental formula without whole proteins or fiber and in place of all food. Bacteria feed on fiber and full proteins so using a semi-elemental diet to treat SIBO will not have the same effect. However, a semi-elemental diet can be a helpful supplement for those with chronic SIBO who want a simple source of nutrition that allows the gut to rest.

Elemental Diet Does Not Contain:

  • Full proteins or peptides
  • Complex Carbohydrates or fiber
  • Other food ingredients

When to Use an Elemental Diet for SIBO?

The elemental formula is one of the best treatment options for SIBO. It can be an effective option even if a patient doesn’t respond to other antimicrobial therapies. If a patient has the willpower to go through with this treatment option it is highly recommended. It is not without it challenges though! In specific cases it is especially recommended:

  • Very high gas levels
  • Methane positive (methane can be tougher to treat)
  • Sensitive to herbs and medications
  • Super restricted diet
  • Has been resistant to other treatments and antibiotics
  • Patient prefers natural option

What to Expect During Elemental Diet Treatment

It is very important to understand the possible side effects when treating with an elemental diet. This will help ease the transition into the all liquid diet and help you weather the storm when you do experience any side effects. The first week of the diet is usually the most challenging and I can personally confirm that to be true in my own experience.

Typical Side Effects People Experience:

  • Headaches (allowed to take some Tylenol or Advil)
  • Diarrhea (May become explosive at times so make sure there is a bathroom nearby)
  • Constipation
  • Cramps
  • Body aches & pains as well as fatigue
  • Aggravation of symptoms
  • Lightheadedness if you wait too long to drink the food because of blood sugar swings
  • Mouth can get nasty because of the simple sugars you drink all the time. Brush teeth more frequently

My Personal Experience:

The elemental diet can be a challenge, but most of the time it’s totally worth it. I definitely experienced some annoying symptoms while undertaking the diet and it took total commitment to get through it. Even though it can be a challenge, I totally recommend it because after I was done my gut felt so much better. I created a PDF that details my journey with the 14 day elemental diet so that you can do it with clear expectations.

SIBO Elemental Diet Buying Guide

There are 3 main elemental formula options for SIBO treatment.  I have experience using the ready made packets and also making my own formula as I did the elemental diet protocol a couple times. I have also taste tested the Physicians Elemental Formula and thought the taste was really good. Below is my breakdown of the 3 elemental diet drinks used.

Products You Can Take

  1. Vivonex Plus Elemental Formula (Product used in research)
  2. Physicians Elemental Formula by Integrative Therapeutics (Need prescription)
  3. Homemaking your own formula

Physicians Elemental DietNewest formulation

HomemakingCan pick your own ingredient sources
Anyone can order online
Requires much more planning and calculating

Summary:

  • I think the easiest option would be to order the Vivonex Plus for 14 days if you don’t have a problem getting used to the taste. Most people find that at the beginning of the diet they think the taste is unpleasant but as they get used to it they are fine. I have found that when your body gets hungry and you’re not eating for pleasure it doesn’t matter as much.

  • The physicians elemental diet is probably the best overall product but you will have to get a prescription from your doctor who will need to contact Integrative Therapeutics.

  • If you have the time and are willing to calculate the amounts of specific ingredients you need to make your own elemental diet, the homemaking option can be a good. This option is just more of a hassle to organize. I have made my own before and found it to be a good option if you have the time.

Elemental Diet Dosage

You need to make sure to get sufficient calories while doing an elemental diet for 2-3 weeks. You do not want to lose too much weight on this diet so be sure to drink all of your formula. Below are the number of packets per day for Vivonex Plus. If you go with Physicians Elemental Diet you will need to go to their website and total up the number of scoops you need for the duration of the diet.

To figure out the total amount of physicians elemental formula you need to order from their site you first find out how many calories you need per day, then find out how many scoops that equals, then multiply the number of scoops per day by 14 for the duration of the treatment.

When living on the elemental diet you have the option to space out your shakes or drink them consistently throughout the day. From my experience, I would recommend drinking the liquid nutrients evenly throughout the day instead of waiting too long to drink the formula. When I waited too long I experienced some dizziness due to the blood sugar swings.

I recommend working with your doctor to determine your caloric needs.

There are a few different semi-elemental formulas on the market.

If you want a highly effective proven way to treat SIBO the elemental diet is a great option. Make sure you consult with your doctor and get help from them throughout the process as well. It can be a challenge to adjust at first but with some perseverance you can get through the 2 week treatment.
