Healthy bacteria are essential for your gut health and immunity. Two Australian companies have created special coffees containing supposedly good bacteria. But is bacteria in coffee good for you?

An Australian company goodguts makes probiotic coffee called Gut Alchemy that manage to survive digestion to reach your gut alive.

KOMBUCHA To Improve Your Microbiome...

In contrast, coffee created by Queensland-based Coffee Roasters Australia in association with Griffith University, has created the first postbiotic coffee blend using dead bacteria.

This new postbiotics coffee blend called BruLife can be used as Nespresso pods or freeze-dried coffee powder.

BruLife say they have “25 Billion Good Bacteria in each Sachet & Capsule!” Sounds scary but it is supposed to be good for you!

BruLife have three coffee blends…

  • Inspire. This blend contains Lactobacillus paracasei bacteria, Ginkgo Biloba, Gotu Kola, Organic Siberian Ginseng (Eleutherococcus), Schisandra Extract, Bacopa Monnieri Extract, Maltodextrin, Vitamins (Pyridoxine Hydrochloride (Vitamin B6), Vitamin E, Folic Acid (Vitamin B9), Cyanocobalamin (Vitamin B12).
  • Immune. This is the main coffee blend containing all five postbiotic bacteria and roasterd Brazillain coffee beans.
  • Renew. This blend contains 3000mg pure collagen in addition to Lactobacillus plantarum bacteria.

BruLife uses a blend of organic Ethiopian, Colombian, and Nicaraguan coffee beans.

The coffee is roasted, blended, and packed in BruLife’s facility on the Gold Coast, Australia.

All of these bacteria are shown to be beneficial for your gut health, your microbiome, and your immunity.

What Are Probiotics?

Probiotics are “friendly” or “healthy” live bacteria that help support good health when eaten or drunk. Probiotic bacteria can be found in fermented foods, yogurt, or supplements.

Not all probiotic strains are the same. Different strains offer different benefits and some probiotic strains survive manufacturing, shelf life, temperature, and digestion better than others.

Many probiotics are destroyed by stomach acids so don’t make it to your gut alive or in the numbers that your gut needs to operate optimally.  

However, the probiotic coffee developed by goodguts is supposed to survive the acids and bring balance back to your microbiome. It does this by producing lactic acid which supports good bacteria you already have in your gut while displacing the harmful or ‘bad’ bacteria that can lead to tummy troubles. (goodguts).

Goodguts also claim that their probiotic is 10 times more likely than yogurt cultures to make it to your gut alive and get to work.

The probiotic they use in their Gut Alchemy coffee beans is 20 probiotic doses of Bacillus coagulans GBI 30-6086 (USA).

What are Postbiotics?

There are two concepts of postbiotics…

  1. They are the bioactive molecules that probiotic bacteria produce when they consume prebiotic fiber (healthline).
  2. They are prebiotics that have been killed by heat. That is, a collection of dead but beneficial bacteria.

BruLife uses bacteria killed by heat before they put it in their coffee.

What are Prebiotics?

Prebiotics are food for our good gut bacteria and they nourish the gut bacteria. Prebiotics are specific types of fibre, nondigestable carbohydrates in our food, that our gut cant digest but feeds the bacteria in our gut. Some people find that prebiotics can cause symptoms like wind and bloating. (goodguts).

What is a Probiotic Coffee?

A probiotic coffee is a roasted coffee with one or more strains of bacteria added.

Drinking this type of coffee supposedly helps supports your health and immune system.

What is Lactobacillus?

Lactobacillus is the largest genus within the group of lactic acid bacteria and plays an important role in human health.

 Lactobacillus is the most common probiotic found in food, and it is diverse in its application to maintain human life and well-being (BruLife).

What is Bifidobacterium?

Bifidobacterium are one of the major genera’s of probiotic bacteria that make up the gastrointestinal tract microbiota in mammals. They help the host perform essential functions such as digestion and staving off harmful bacteria (BruLife).

What Does Bacteria Coffee Taste Like?

You can’t taste any of the probiotic or postbiotic bacteria. You only taste the roasted coffee.

The Gut Alchemy coffee is made from 100% Arabica coffee beans from South America. It has the following taste characteristics…

“Full-bodied coffee that carries through milk with honeycomb, spiced biscuit and vanilla. Finishes with clean, lingering complexity. It has won multiple awards.”

BruLife’s Immune, Inspire, and Renew blends are all made from Arabical coffee beans from Brazil so they all have the taste characteristics of

Medium acidity and body. Dark cacao and roasted nut aroma. Notes of milk chocolate and roasted nuts with a sweet redcurrant acidity

The blends differ in their bacterial and other components.

Other Bacteria Coffee Blends

Researchers from the National University of Singapore recently published data on a new fermented coffee beverage that includes probiotic bacteria and yeast. In particular, they use live Lactobacillus rhamnosus and Saccharomyces cerevisiae var. boulardii. However, there does not yet seem to be a commercial product as yet.

Other coffees may be advertised as containing probiotics, but this is usually through the addition of mushrooms or as part of a ‘superfood’ or diet coffee.

I will try and keep this post updated with other new genuine probiotic or postbiotic coffees as I discover them!

The Importance Of Gut Health

Your gut bacteria (the microbiome) is essential for your health (examine.com).

And gut health is quickly becoming a health priority for many people. 

There is an increased focus on probiotics being a part of the solution, but some popular probiotic offerings are incompatible with many diets and health requirements. 

Some people require a novel solution and this can be these postbiotic and probiotic coffees we have discussed in this post.

Conclusion

If you want to improve your immunity and gut health then maybe one of these new bacterial coffees are worth a try?
