4 Week Gut Protocol Key Ingredients – Are they Safe & Effective?

We researched the ingredients in both the Revitalize and the Optimize formulas. Take a look at the following breakdown:

4 Week Gut Protocol Revitalize:

Bacillus Coagulans

Bacillus coagulans are strains of probiotic cultures that have been linked to improved bowel conditions as we see in the following National Institutes of Health quote:

Some strains of B coagulans have shown clinical efficacy by significantly improving the bowel pattern, diarrheal duration and frequency, abdominal pain, and bloating associated with IBS through randomized control trials (RCTs) studies[1].

But the report goes on to mention that during most tests, variances were not taken account for as we see here:

However, few of these clinical studies have also reported about variable effect of B coagulans strains for IBS symptoms instead of complete relive of symptoms subset.


Inulin is a type of fermentable fiber that is broken down in the gut to create metabolites. These metabolites may have a beneficial impact on digestion as we see in the following NIH study quote:

Recently, several studies have found that dietary supplementation of inulin can improve metabolic function and regulate intestinal immunity. Inulin is fermented in the colon by the gut microbiota and a series of metabolites is generated[2].

4 Week Gut Protocol Optimize:


Bromelain is an enzyme that is produced naturally in pineapples. Some studies have shown that it has antithrombotic and anti-inflammatory properties which may help protect the digestive tract. However, gut-specific studies are lacking[3].

Japanese Sophora Powder

This powder is extracted and produced from the Japanese Sophora flower. While this substance has been linked to anti-inflammatory effects in the intestines, there have been no conclusive studies that confirm this possible benefit[4].


Papain is an enzyme that is extracted from the papaya fruit plant. The National Institutes of Health had the following to say about its effects on weight loss and digestive function:

While it is widely accepted that C. papaya can help digestive disorders and weight loss by people in the tropics, it is still unclarified the role of papain in beneficial effects[5].

So it is possible that this specific extract of the papaya plant may not be as beneficial as the fruit itself for weight loss and digestive function.
