Understanding PREbiotics, PRObiotics, and POSTbiotics

A healthy digestive system is essential for a healthy life. Without it, your body can’t convert your food into the nutrients and energy you need to survive. So, how can you support your digestive system and help it thrive? Simple, with PRObiotics like Probulin®.

PRObiotics. We’ve all heard of them and probably consume them every day without even thinking about it. You can get probiotics as a dietary supplement or find them in foods ranging from chocolate and enhanced yogurt to protein bars and powders. 

But what is a PRObiotic, and how does it help keep your digestive environment strong and healthy? And what about PREbiotics and POSTbiotics? Let’s start by looking at a few definitions of PRObiotic.


PRObiotics: The “Good” Gut Bacteria

A PRObiotic, according to Merriam Webster, is a microorganism (such as a lactobacilli or bifidobacteria) that, when consumed (as a food or dietary supplement), helps to maintain and restore beneficial bacteria to the digestive tract

The World Health Organization refers to PRObiotics as microorganisms that, when consumed in adequate amounts (10 to 20 billion CFU), infer a benefit to the host.

In other words, PRObiotics are the “good bacteria” that support the health of your digestive system. Without a proper balance of beneficial PRObiotic organisms, it’s hard to achieve or maintain optimal health.

Countless studies have linked PRObiotics to the support of a healthy immune system, healthy motility function, proper digestion and so much more. Bottom line, the better your digestive environment functions, the better your whole body may function.

It’s important to note here that the myth of “more is better” simply doesn’t hold true in the case of PRObiotics; taking more than the suggested amount of a PRObiotic generally doesn’t give you any extra benefit. Not only that, but taking a wider variety of strains may not help either. Focusing on taking the correct amount of scientifically documented strains, like may of the strains found in Probulin®, we believe may be on of the best ways to use PRObiotics to support digestive balance.


PREbiotics: Food for PRObiotics

All living things need food, even PRObiotic bacteria. Have you heard of a PREbiotic? It’s the part of soluble fiber that is a food source for PRObiotics. You probably already know how important fiber is for your diet and this is largely because of its role as nourishment for PRObiotic bacteria in your digestive tract. When properly fed, PRObiotic bacteria are much healthier—and their health is important to your health.


POSTbiotics: The Result

Now, a new term. Are you familiar with POSTbiotics? They are what we refer to as the 3rd leg of the stool, in the gut bacteria cycle needed for what we believe to complete digestive health. A POSTbiotic is defined as any compound created by PRObiotics as they live and thrive in the digestive system. 

Put simply, when PRObiotics consume PREbiotic fiber, the result of that is POSTbiotics. So, while POSTbiotics are essentially PRObiotic “waste,” these compounds may have several important health benefits. 

POSTbiotic compounds created by PRObiotics may include:

  • Vitamins, including Vitamins K and B-12
  • Amino Acids
  • Bacteriocins (natural compounds that destroy harmful organisms)
  • Short chain fatty acids (that can become nourishment for the body and help to promote the growth of beneficial PRObiotic bacteria in the body)
  • Other organic acids and metabolites that support overall health


We feel that having All Three is key—Plus Protection

When looking for an effective, quality PRObiotic it’s very important to make sure it contains a PREbiotic and POSTbiotic, as well as a scientifically validated delivery system to help ensure better survival of the healthy bacteria as they make their way through your digestive system. 

One such delivery method is Probulin’s MAKTrek® 3-D Probiotic Delivery System. This proprietary technology protects PRObiotics with a uniquely harvested seaweed extract along with an all-natural buffering system to help support the condition of the in-transit digestive environment. 

Provide a Secure Home for Your Healthy Gut Bacteria

In summary, if you want to take digestive health to the next level and be sure that your PRObiotic supplement is doing all it can to support you, make sure that it also contains: 1) a PREbiotic, 2) an effective delivery system, and 3) a POSTbiotic. 

These elements provide a comfortable “home” for your PRObiotic: The PREbiotic is the well-stocked pantry nourishing it, the delivery system is the walls and roof protecting it, and the POSTbiotic is an herbal tea energizing and hydrating it. We believe that together, they put the PRObiotic in the best position possible to promote digestive health and support your body’s inherent ability to heal itself. 

Live a healthier and a more balanced life by making a well-formulated probiotic like Probulin® a part of your daily routine.
