Probiotics Vs Prebiotics

In recent years, our microbiome has been in the scientific spotlight with ever-increasing evidence supporting the role our gut plays in health and disease.

The more the gut is researched, the stronger the message that maintaining a healthy gut could be the single most important thing we do to sustain our health.

Our microbiome has been extensively studied, with low bacterial diversity and population showing more frequently in those suffering from chronic health disease.1

Numerous studies have also shown a change in gut microbiota with obesity, cancer, and even types of neurodegenerative disease.2

It is, therefore, important to explore what we can do to populate our guts with a healthy and diverse microbiome to help boost overall health.

What are Probiotics & Prebiotics?

To simply put it, probiotics are live microorganisms, which help populate our gut with beneficial bacteria.

Probiotics mimic the beneficial bacteria that are already in our gut and have been shown to reduce inflammation, improve the microbiome and reduce gastrointestinal symptoms such as bloating, diarrhoea and constipation.3

Prebiotics (not to be confused with probiotics) are a food supply for the bacteria living in our gut and are mostly found in high fiber foods which aren’t broken down in the digestive tract by human enzymes.4

An important process made from prebiotic fermentation is the creation of short-chain fatty acids (SCFAs), which are incredibly vital for our health.

SCFAs are made from the breakdown of fiber-rich carbohydrates by our gut bacteria in the large intestine and go on to produce many proteins and molecules for many processes in the body.

Probiotic Food Sources

As most of our microbiome lives in our intestines within the GI tract, what we eat is a huge factor in what influences our gut microbiome.5


Tempeh is made from a process of fermenting soybeans, making them much easier to digest. Studies show regular intake of tempeh increases beneficial bacteria in the gut.6


This probiotic-rich food is produced from fermenting vegetables in beneficial lactic acid bacteria (LAB).7

Many healthy functional foods can be used i.e. ginger, garlic, red pepper, and cabbage, making kimchi an incredibly healthy addition to a meal. A popular dish in Asian cooking, Kimchi is typically served with steamed rice.


Kefir is made from soaking kefir grains in raw milk (or water) to produce a healthy mix of yeast and bacteria strains.

This healthy drink has been shown to be antifungal, antibacterial, anti-allergic, and potentially anti-cancerous.8

Prebiotic Food Sources


Flaxseeds contain lignans, a potent plant compound that contains antioxidant and oestrogenic benefits.

The most notable benefits of flaxseeds are their effect on blood glucose levels, reducing constipation, and weight management.9


Rich in Fructooligosaccharides (FOS), garlic has been studied for its effects on the cardiovascular system by reducing lipid levels, as well as improving digestion by relieving constipation.10

Allicin, an enzyme released when crushing garlic, has antifungal and antiparasitic benefits.11


For the antioxidant effects of dark chocolate, a high percentage of cocoa is required (look for 70% and higher for dark chocolate).

Cocoa has been shown to reduce blood pressure along with stabilising insulin levels and improving lipid metabolism.12

Fermented food sources Non-fermented food sources
Food Sources: Kefir, Miso, Sauerkraut, Kombucha, sourdough, kimchi, tempeh Food Sources: Asparagus, Jerusalem artichokes, garlic, chicory root, cocoa, berries, konjac root, bananans, seaweed14

Both probiotics and prebiotics help to increase nutrient absorption in the digestive tract,13 and help to improve the gut microbiome.15

The Gut Co. Probiotic Supplements

Another popular way to increase the beneficial bacteria in your gut is to take a supplement.

Important considerations to make when choosing a probiotic is that it is broad-spectrum (multiple strains) and has a minimum of 1-2 billion CFU (amount of bacteria present) per dose.16

The Gut Co. formulations are broad-spectrum and contain a minimum of 5 billion CFU in each tablet.

The Gut Co. provides one-a-day probiotic supplements enriched with inulin (a potent prebiotic). This ensures that once the live microorganisms from the supplement reach your gut, a prebiotic to help feed healthy bacteria is also present.

These supplements also contain a cocktail of time-released antioxidants and vitamins and minerals, ensuring that as the capsule moves throughout each part of the digestive tract, each ingredient is absorbed at the most effective time for maximum absorption.


Many supplements on the market are formulated to be taken in multiple daily doses. The Gut Co. formulations are designed to fit in with a busy lifestyle and are to be taken once daily (AM).

If pregnant, breastfeeding, suffering from food allergies, or under medical supervision seek professional advice before using.
