FREQUENTLY ASKED QUESTIONS

Primal Gut Restore is a complete gut health formula. Containing pre, pro, and postbiotics, Primal Gut Restore supplies your body with the most beneficial probiotic strains, and all of the elements you need to destroy harmful bacteria. This revolutionary blend boosts immune function and helps build the foundation for healthy probiotic colonization!
Probiotic strains are the different types of probiotics that have been isolated and defined by scientists. Strains have different effects on the body; some are great for digestion, while others are perfect for building a strong immune system or decreasing your cholesterol.
You already have well over 500 different probiotic strains in your body at this very moment!
Prebiotics are the non-digestible fiber found in many foods. These prebiotics pass through your small intestine and then become fermented before they reach the large intestine.
It’s here that prebiotics serve as a food source for probiotics, allowing them to grow and thrive within your gut's microbiome.
ServiPostbiotics are what results when prebiotics are used by probiotics. They are the beneficial ‘waste’ of probiotics, in a sense, where many of the benefits of probiotics are produced. Primal Gut Restore includes pre, pro, and postbiotics to deliver the maximum benefits and offer a complete three-step approach to gut health.
Did you know that 70% of the body's immune cells are located within your gut? Primal Gut Restore is the only probiotic supplement that takes everything into consideration. You wouldn’t build a house on sand, so why would you invest in probiotics without creating the perfect environment for them to survive and thrive? Primal Gut Restore, gives you everything you need to create the perfect environment, build a healthy colony of probiotics, the food they need to survive and thrive, and lastly, everything you need to destroy harmful gut bacteria.
CoreBiome® is a unique derivative of a short chain fatty acid called butyrate, which is naturally produced by healthy bacteria in our gut when we eat vegetables.

Butyrate is the primary fuel source for the cells of our gut lining, and thus supports digestive health and immune function. While “regular” butyrate is primarily used in the stomach and small intestine, CoreBiome® gets to the colon where it is most needed to support immune health. THIS IS FUNDAMENTALLY IMPORTANT and explains why CoreBiome® is the single most important POST-BIOTIC.

We have built this product to be shelf-stable with a significant overage on total cell enumeration. Probiotic bacteria can be sensitive to certain environments, that’s why we keep them temperature controlled throughout the entire production process, including storage in our warehouse.

Although Primal Gut Restore was specially formulated to maintain maximum efficiency and shelf life when stored in a cool, dry place away from moisture, and outside of direct sunlight, we recommend refrigerating your product after opening to ensure maximum benefits.
Stability studies show that full potency and cell count will be maintained for 18+ months if unopened and stored properly. After 18 months the probiotic is at risk of a decrease in potency and cell count.

Once opened, we recommend finishing an opened bottle within 90 days and storing the opened bottle either in low-moisture conditions or in the refrigerator.

OUR BENEFITS

Powerful, carefully sourced, all-in-one formula for overall health

THE MOST COMPLETE GUT HEALTH FORMULA 

Give your gut everything it needs with this powerful three-tier approach to comprehensive gut health. Featuring fast-acting, cutting-edge patented technology, this complete package uses the power of prebiotics, probiotics, and revolutionary CoreBiome® postbiotic technology to strengthen your gut lining, restore balance, and promote long-term gut health.*

Those who suffer from seasonal allergies have been found to lack diversity in their gut bacteria.

By introducing powerful helping bacteria, Primal Gut Restore gets to the root of the problem to naturally decrease the severity of most seasonal allergy symptoms.*

REDUCE THE EFFECTS OF SEASONAL ALLERGIES 

GOOD HEALTH STARTS IN THE GUT

You might not know this but the gut is home to 70% of the body’s immune cells. Primal Gut Restore is uniquely crafted with CoreBiome® postbiotics which serve as the primary fuel source for the cells of the gut lining, thus supporting digestive health and immune function.

While “regular” butyrate is primarily metabolized in the stomach and small intestine, CoreBiome® gets to the colon where it is most needed to support immune health.*

REDUCE HARMFUL GUT BACTERIA

An overgrowth of harmful bacteria in the gut can damage a healthy digestive tract and lead to many health concerns, such as weakened immune system, fatigue and loss of overall health and many other health concerns.

Gut Restore was formulated to help reinstall balance to your gut health by helping good bacteria flourish.*

PROMOTES HEALTHY GUT BACTERIA

There are thousands of different types of bacteria in your intestines that collectively make up your microbiome. Your microbiome is responsible for controlling the digestion of food, immune system and central nervous system function, as well as impacting healthy sleep, mood, brain health, and other bodily processes.*

POSTBIOTICS FOR MAXIMIUM POTENCY

Postbiotics are the byproduct when probiotics feed on prebiotics. Less widely known than pre and probiotics, postbiotics provide the bases for a strong and healthy gut microbiome.

Recent research has even found that most of the benefits we attribute to probiotics are actually due to postbiotic activity.*
