What Are Probiotics? A Complete Guide to Gut Health and Live Cultures
Probiotics have become one of the most widely discussed topics in digestive health. From yoghurts and fermented foods to high-strength supplements, probiotics are now a regular part of many people's wellness routines.
Despite their growing popularity, many people are still unsure what probiotics actually are, how they work and whether they are worth including as part of a healthy lifestyle.
In this guide, we'll explain what probiotics are, explore their relationship with the gut microbiome and discuss why they have become such an important area of modern health research.

What Are Probiotics?
Probiotics are live microorganisms that are commonly consumed through foods and dietary supplements. These microorganisms are often referred to as "friendly bacteria" because they naturally occur within the digestive tract as part of the gut microbiome.
The human digestive system contains trillions of microorganisms, including bacteria, yeasts and other microbes. Together, these organisms form a complex ecosystem known as the gut microbiome.
Scientists continue to study how these microorganisms interact with the body and contribute to digestive balance and overall wellbeing.
Understanding the Gut Microbiome
The gut microbiome is the community of microorganisms that live within the digestive tract.
Every person has a unique microbiome influenced by factors such as:
- Diet
- Age
- Lifestyle
- Environment
- Medication use
- Physical activity levels
- Sleep quality
Researchers estimate that trillions of microorganisms live inside the human digestive system. Maintaining a diverse and balanced microbiome is an important area of ongoing scientific research.

How Do Probiotics Work?
Probiotics work by introducing live cultures into the digestive system. Different probiotic strains possess different characteristics and are therefore commonly combined into multi-strain formulas.
This is one reason why many modern supplements contain multiple probiotic strains rather than a single culture.
For example, broad-spectrum formulations may contain 10, 14 or even more individual strains, providing greater diversity within a single supplement.
Our own Probiotics 50 Billion CFU & 14 Strains combines fourteen carefully selected strains in a convenient daily capsule.
Where Do Probiotics Come From?
Probiotics can be found naturally in fermented foods and drinks.
Examples include:
- Yoghurt
- Kefir
- Sauerkraut
- Kimchi
- Miso
- Kombucha
- Tempeh
Many people choose probiotic supplements because they provide a convenient and consistent way to incorporate live cultures into their daily routine.
Common Types of Probiotic Bacteria
Not all probiotics are the same. Different strains belong to different bacterial families.
Some of the most commonly used include:
Lactobacillus
Lactobacillus strains are among the most widely studied probiotic bacteria and are commonly found in fermented foods.
Bifidobacterium
Bifidobacterium strains naturally occur within the digestive tract and are frequently included in multi-strain probiotic supplements.
Saccharomyces
Saccharomyces is a beneficial yeast commonly used in certain probiotic formulations.
What Does CFU Mean?
When shopping for probiotic supplements, you'll often see the term CFU.
CFU stands for Colony Forming Units.
This measurement is used to indicate the number of live microorganisms present within a probiotic supplement.
Products can vary considerably, ranging from a few billion CFU to over fifty billion CFU per serving.
However, probiotic quality is not determined solely by CFU count. Strain diversity, manufacturing standards and storage conditions can also play important roles.
What Is a Multi-Strain Probiotic?
A multi-strain probiotic contains multiple types of beneficial bacteria within a single formula.
Many modern supplements use multi-strain approaches because different strains may offer different characteristics.
Examples include:
- 5-strain formulas
- 10-strain formulas
- 14-strain formulas
- Broad-spectrum probiotic blends
Multi-strain supplements have become increasingly popular among consumers looking for comprehensive digestive support.
Probiotics and Daily Wellness
Interest in probiotics continues to grow as researchers learn more about the relationship between the gut microbiome and overall wellbeing.
Many people include probiotics as part of a wider wellness strategy that also focuses on:
- Eating a varied diet
- Increasing fibre intake
- Staying hydrated
- Managing stress
- Regular physical activity
- Maintaining healthy sleep habits
Gut health is influenced by many factors, which is why probiotics are often discussed alongside broader lifestyle habits rather than viewed as a standalone solution.
Probiotics vs Prebiotics
One of the most common questions is the difference between probiotics and prebiotics.
Probiotics are live microorganisms.
Prebiotics are fibres that provide nourishment for beneficial bacteria already present within the digestive system.
Foods rich in prebiotics include:
- Garlic
- Onions
- Leeks
- Asparagus
- Bananas
- Oats
Because they play complementary roles, probiotics and prebiotics are often discussed together.

Choosing a Probiotic Supplement
When selecting a probiotic supplement, there are several factors worth considering:
- Number of strains included
- CFU count
- Manufacturing standards
- Ingredient quality
- Suitability for your dietary preferences
- Brand reputation
High-quality supplements should clearly state their strain count and CFU content on the label.
