Probiotics vs. Microbiomes: What is the Difference?

In the world of gut health, the terms probiotics and microbiome are often used interchangeably. Understanding the difference can help you make informed choices for your digestive and overall health.

What Is the Human Microbiome?

The microbiome refers to the entire community of microorganisms, bacteria, fungi and viruses, that live in and on your body. The gut microbiome plays a crucial role in digestion, immune function, and even mental health. A balanced microbiome supports overall well-being, while an imbalance can contribute to issues like poor health.

What are Probiotics?

According to the widely recognized FAO/WHO definition (2001), revised by Hill et al. (2014), probiotics are defined as “Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host”.

When combined with the specifications outlined by the FAO/WHO Working Group for the Evaluation of Probiotics in Food (2002), the key aspects of this definition include:

• A probiotic must be alive when administered
• A probiotic must be scientifically substantiated in regard to its health benefit in the target host
• A probiotic must be a taxonomically defined microorganism or combination of microorganisms (genus, species and strain level)
• A probiotic must be safe for its intended use

The Key Difference

Think of the microbiome as an entire ecosystem, while micro-organisms are just one group of helpful bacteria within it. The best way to support your microbiome is to take a diverse diet in fibre  and lead a healthy lifestyle. You can also compliment this by taking supplements.

By understanding the difference between probiotics and the microbiome, you can take a more holistic approach to gut health, ensuring your body has the right balance of bacteria to thrive.
