NIH Studies: Effects of Fermented Foods on Animal Health

Many pet owners, farmers, and equestrians have only recently begun to learn about the benefits of fermented foods in promoting GI health and overall vitality. From maintaining pet gut health to getting the most from your horse feed, fermented foods are increasingly becoming a natural remedy to help nourish animals from the inside out. Some are shown to promote profound health benefits  

But what is it that makes fermented foods and supplements so special? Let’s dig into what the research says to learn more.

Understanding Fermented Foods: A Natural Resource for Animal Health

Fermentating certain foods is an ancient process in which microorganisms such as bacteria and yeast, break down sugars and starches, giving food a more complex, bioactive form. 
In addition to preservation, fermentation can actually change the nutritional composition of food.  It can enrich the original ingredient(s) with unique properties, some of which positively affect the GI Tract and Microbiome balance in animals.

  • Role in Pet Diets: The presence of fermented ingredients can provide digestive support for pets.  Some also include probiotics for animals to support a balance in the gut microbiome.
  • Natural Feed: Some horse feeds and equine diet supplements include fermented ingredients to aid in digestion.
  • Fermented wheat germ extract is a unique natural ingredient whose benefits are somewhat unique among fermented foods.  It has been well studied and received for its positive influence on gut flora and metabolic processes.
  • Immune System Interaction: The exposure to immune-boosting supplements shows the ongoing interest in how fermentation promotes health beyond digestion.

Key Findings from NIH Studies on Fermented Foods for Animal Health 

​While direct NIH studies on fermented foods for animal health are limited, existing research and related studies offer valuable insights into their potential benefits.​

Key Findings from NIH Studies on Fermented Foods for Animal Health


Fermented Wheat Germ Extract (FWGE):

  • Metabolic Function: FWGE has demonstrated significant antiproliferative and anti-oxidative effects that can help animals keep weight, be calmer and build muscle.
  • Immune System Enhancement: Research indicates that FWGE can help promote immune responses, potentially enhancing the body's defence mechanisms.

Fermented Vegetables for Dogs:

  • Probiotic Benefits: Incorporating fermented vegetables into canine diets can introduce beneficial probiotics, supporting digestive health and enhancing immune function.​
  • Enhanced Nutrient Absorption: Fermentation can increase the bioavailability of nutrients in vegetables, making them more accessible for absorption in dogs.

Fermented Food Supplements:

  • Nutrient Density: Fermented supplements often contain higher concentrations of vitamins, minerals, and bioactive compounds, contributing to overall animal health. ​
  • Antioxidant Properties: These supplements can provide antioxidants that combat oxidative stress, supporting cellular health in animals.

Fermented Dog Food:

  • Digestive Health: Fermented dog foods can introduce beneficial bacteria into the canine gut, aiding digestion and promoting a balanced microbiome.​
  • Immune Support: The effects of fermented dog food on the microbiota can promote immune responses, helping dogs fend off pathogens and environmental contaminants more effectively.​

Horse Supplements:

  • Joint Health: Certain fermented supplements, such as FWGE, have been shown to promote joint health and mobility in horses.​
  • Inflammatory Response: FWGE supports a normal inflammatory response and provides antioxidant benefits, contributing to improved joint function and comfort.

Comparing Fermented Diets with Traditional Animal Nutrition

The traditional versus fermented debate for pet and livestock nutrition is a hot topic with flavourful discussions surrounding it. Many pet owners feed kibble or raw food; farmers use standard feeds for livestock. 
This is in contrast to fermented foods for dogs and other animals, which are gaining popularity because of their unique nutritional benefits. But how do they stack up against conventional diets? Let’s break it down.

Traditional Diets: The Default Setting

1. Kibble and raw diets can be deficient in probiotics needed for microbiota balance.  Digestion and absorption of nutrients may not be completely maximized without those good bacteria.
2. Common livestock feed helps with growth but does little to support digestion or immunity. Animals eating these diets may suffer from digestive upset or imbalanced gut flora.

Fermented Diets: An Innate Advantage

1. Fermented dog food and fermented vegetables for dogs can allow for good bacteria to flourish and aid in digestion. These are known to support the gut microbiome which in turn supports overall health.
2. Fermented Wheat Germ Extract (FWGE) can help support immunity and nutrient absorption.  The active ingredient contains unique bioactive compounds that help support metabolic pathways, stress responses and the Microbiota. 

Real-World Benefits of Fermented Foods: What Equine and Pet Owners Are Saying? 


More pet and horse owners are discovering the power of Fermented Wheat Germ Extract (FWGE) in promoting GI health, immunity, and overall well-being. From adding sauerkraut for canines to experimenting with organic horse feed, real experiences highlight the impact of these foods on animal health.

Pet Owners’ Experiences with Fermented Foods

  • Many dog owners report that incorporating probiotics for animals and digestive support for pets can help with food sensitivities, and support energy levels.  However, if the dog’s own immune system isn’t able to provide the environment for those bacteria to flourish, the results can vary.
  • Supplements like Immunovet K9, made with fermented wheat germ extract (FWGE), provide tremendous immune and digestive benefits. FWGE helps balance pet gut health, supporting a healthy pet diet and overall vitality.

Equine Owners' Success Stories

  • Horse owners using immune-supporting supplements like Immunovet EQ have noticed better digestion, shinier coats, and endurance in their horses.
  • Immunovet’s FWGE promotes joint health and mobility in horses. FWGE supports a normal inflammatory response, provides antioxidants, and contributes to support joint function and comfort.

Why Immunovet Stands Out in the World of Fermented Animal Supplements? 

In the growing world of fermented animal nutrition, Immunovet has been a trusted name for more than 20 years, offering unique natural supplements for both horses and dogs.  No other supplement or feed contains this proprietary active ingredient or formulation.

While many products claim to support digestion and immunity, Immunovet EQ and Immunovet K9 set a new standard with their unique active ingredient - Fermented Wheat Germ Extract (FWGE)—a game-changing plant based substance backed by over 20 years of research.

Immunovet EQ: Supporting Equine Nutrition

  • Designed to be taken at meal time, Immunovet EQ promotes nutrient absorption and digestion of horse feed.
  • The fermented properties help maintain gut microbiome balance, making it a must-have equine diet supplement for performance horses and pleasure horses alike.
