What Can Negatively Affect Your Digestive System?

Poor Diet


A diet lacking important macro nutrients such as fiber found in fruits and vegetables make it difficult for the living bacteria in the digestive system to survive. This important fiber is often referred to as a Prebiotic which is the food they eat.


Ingesting various chemicals can disrupt the balance of healthy bacteria.

Insufficient Water

Insufficient Water

Like any living thing water is key to survival.

Unhealthy Habits

Lifestyle Habits

Tobacco products, alcohol consumption, and many other choices may influence digestive health among other things.



Emotional health is of great importance to overall health. Research suggests that occasional stress and sleeplessness may affect the digestive environment.

Environmental Exposure

Often we are exposed to things like chlorine & fluoride, and many other elements in our environment, and this may have an impact on digestive health.

Research shows probiotics may support:

How do you choose the best probiotic?


Prebiotics Included

You want your probiotic to include a PREbiotic fiber.  PREbiotics, like Inulin, are food for the probiotics and necessary for their survival.


More is Not Always Better

Taking more billions CFU (colony forming units) is NOT necessarily more effective. Evidence suggest more than 10-20 billion CFU may be unnecessary, especially if delivered properly.


Delivery Is Critical

Effective delivery of probiotics to the gut is significantly more important than the CFU count. This is why Probulin® uses the scientifically validated MAKTrek® 3-D Probiotic Delivery System.

All Probulin® Digestive Probiotics Ensure Optimal Delivery & Survival in the Gut

STEP #1 — Stomach Acid Protection

Using a uniquely harvested extract of brown seaweed, we have created a secondary barrier to protect the beneficial probiotic bacteria. We like to refer to this as our Seaweed Submarine. Even after the probiotic powder is exposed to 1.5pH stomach acid for 60 minutes, the probiotic bacteria inside the Seaweed Submarine are still dry and protected.

STEP #2 — Isotonic Delivery/Protection

Before activation, the beneficial probiotic bacteria are in a dormant state. These bacteria are activated by exposure to moisture, but once active, they can over-hydrate and die. Using our proprietary isotonic delivery step, we achieve activation with a more balanced hydration. This supports higher survival rates in probiotic bacteria.

STEP #3 — Environmental Safeguards

All strains of probiotic bacteria used in Probulin® probiotics are resistant to many pressures created by environmental exposure to common everyday elements.

The MAKTrek® 3-D three-step system has scientifically demonstrated an ability to ensure a greater number of surviving beneficial probiotic bacteria — beyond other probiotic delivery systems.

What ingredients are in Probulin® Digestive Probiotics?

Seaweed Extract Electrolytes Minerals Lactobacilli Bacteria Bifidobacteria Prebiotics

Seaweed Extract (Complex Marine Polysaccharides)

Uniquely harvested Brown Seaweed (Lessonia nigrecens) which in used to form our proprietary “Seaweed Submarine” which protects the valuable probiotics from stomach acid and bile.

Electrolytes Minerals

Key to the success of our MAKTrek 3-D Probiotic Delivery System, important electrolyt​e minerals help to support survival of our beneficial probiotic bacteria by helping create an isotonic (“balanced”) water environment.

Lactobacilli Bacteria

Lactobacilli Bacteria are important beneficial probiotic bacteria that primarily live in the small intestines (Upper Gastrointestinal Environment).  The most well-know is Acidophilous which has been studied in areas like immune support.


Bifidobacteria are important beneficial probiotic bacteria that live primarily in the large intestines (Lower Gastrointestinal Environment). These particular type of probiotic bacteria have been studied in the area of support for challenges such as occasional loose bowels and constipation.


Prebiotics are portions of soluble fiber that are the favorite food for beneficial probiotic bacteria. Prebiotics are important food resources for probiotics to ensure better survival. Prebiotic fiber can be found in Inulin as well as many other fruits, vegetables, seed & legumes.
