Probiotics and prebiotics are often discussed together, but they perform different roles within nutrition.
Probiotics are live microorganisms found in certain fermented foods and food supplements. They include various bacterial strains, commonly belonging to groups such as Lactobacillus and Bifidobacterium.
Prebiotics are types of fibre that pass through the upper digestive tract without being fully broken down. They can be used by microorganisms naturally present within the digestive system.
Together, probiotic cultures and prebiotic fibre are commonly included in daily food supplement routines. Understanding the difference between them can help you make informed choices when comparing products and dietary sources.
Daily Flora combines multiple microbial strains with fructooligosaccharide prebiotic fibre and a selection of B vitamins in a convenient 30-day supply.
Understanding Probiotics and Prebiotics
The term probiotic refers to selected live microorganisms included in foods or supplements. Different products may contain different species, strains and quantities, which is why labels often display strain names and colony-forming units, commonly abbreviated to CFU.
Prebiotics are not live microorganisms. They are dietary substances, usually particular types of fibre, that are not completely digested before reaching the lower digestive tract.
Fructooligosaccharides, often shortened to FOS, are one example of prebiotic fibre used in nutritional supplements.
A product described as a synbiotic generally contains both live cultures and a prebiotic component.
Why Probiotics and Prebiotics Matter
The human digestive tract naturally contains a large and diverse community of microorganisms. Its composition can vary between individuals and may be influenced by diet, age, environment and lifestyle.
Fermented foods and live-culture supplements offer different ways to include microorganisms within a varied diet. Prebiotic fibres are found naturally in a range of plant foods and can also be added to supplements.
People may choose combined probiotic and prebiotic products because they provide both components in one structured daily routine.
Rather than being used as a replacement for a varied diet, these products are intended to complement everyday nutritional habits.
Key Features of Probiotics and Prebiotics
Probiotic and prebiotic products are valued for several nutritional characteristics:
Live-culture supplements can provide clearly identified microbial strains.
Prebiotic fibre is distinct from probiotic cultures and performs a different nutritional role.
Multi-strain products combine several types of microorganism within one serving.
Capsules provide a measured and convenient daily format.
Combined formulas can include additional vitamins or nutrients.
Regular use helps make the product part of a consistent nutritional routine.
How Probiotics and Prebiotics Work
Probiotic supplements deliver live microbial strains in a measured serving. The species, strain, quantity and product format can vary considerably between formulas.
Prebiotic fibres resist complete digestion in the upper digestive tract. Once they reach the lower digestive system, they may be fermented by microorganisms present there.
Because probiotics and prebiotics are different, one does not automatically imply the presence of the other. Consumers should check the ingredients and nutritional information to understand exactly what a product provides.
Daily Flora contains 15 listed microbial strains, 600mg of microbial strains and 600mg of fructooligosaccharides per daily serving. It also provides niacin, pantothenic acid, riboflavin, vitamin B6, thiamine, folic acid, biotin and vitamin B12 at the stated nutrient reference values.
Top Ten FAQ's - Probiotics & Prebiotics
What are probiotics?
Probiotics are selected live microorganisms found in certain fermented foods and nutritional supplements.
What are prebiotics?
Prebiotics are dietary substances, usually particular types of fibre, that are not completely digested in the upper digestive tract.
Are probiotics and prebiotics the same?
No. Probiotics are live microorganisms, while prebiotics are substances that may be used by microorganisms already present in the digestive system.
What does CFU mean?
CFU stands for colony-forming units and is used to describe the quantity of viable microorganisms in a probiotic product.
What is a multi-strain probiotic?
A multi-strain formula contains more than one identified microbial strain within the same product.
Which foods contain live cultures?
Live cultures may be found in foods such as live yoghurt, kefir, sauerkraut, kimchi and other fermented foods.
Which foods contain prebiotic fibre?
Sources include onions, garlic, leeks, chicory root, bananas, asparagus, oats and legumes.
Can probiotics and prebiotics be taken together?
Yes. Some products combine live cultures and prebiotic fibre in one formula.
Can live-culture supplements be taken every day?
Many are intended for daily use, but the directions and recommended serving on the individual product label should always be followed.
How should probiotic supplements be stored?
Storage requirements vary. Always follow the instructions on the packaging, particularly regarding temperature, moisture and refrigeration.
Dietary Sources of Probiotics and Prebiotics
Live cultures may be found in fermented foods such as:
Live yoghurt
Kefir
Sauerkraut
Kimchi
Selected fermented vegetables
Some traditional fermented drinks
The presence and quantity of live microorganisms can vary according to processing, storage and preparation.
Prebiotic fibres occur naturally in foods including:
Onions
Garlic
Leeks
Asparagus
Chicory root
Bananas
Oats
Legumes
Eating a broad variety of plant foods is one way to include different types of dietary fibre.
Who Might Consider Probiotics and Prebiotics?
A combined probiotic and prebiotic supplement may appeal to adults who:
Prefer a measured daily source of live microbial cultures.
Want to include prebiotic fibre in their nutritional routine.
Are comparing single-strain and multi-strain formulas.
Prefer capsules to fermented foods or drinks.
Want a structured 30-day supplement routine.
Are looking for a formula containing live cultures alongside selected B vitamins.
Individual requirements vary, and a supplement should be chosen according to personal dietary needs.

How to Include Probiotics and Prebiotics in Your Routine
Live cultures and prebiotic fibre can be obtained through foods, supplements or a combination of both.
When using a supplement:
Follow the directions on the product label.
Take the recommended serving consistently.
Do not exceed the stated daily amount.
Check whether the product has specific storage requirements.
Include the supplement alongside a varied, balanced diet.
Check the strain names and quantities when comparing formulas.

Suitability and Considerations
Probiotic and prebiotic supplements may not be suitable for everyone. Consider the following: Food supplements should not replace a varied, balanced diet. Check the full ingredients list for allergens and dietary suitability. Temporary changes to normal digestion may occur when increasing fibre intake. People with underlying health conditions should seek professional advice. Anyone taking prescribed medication should consult a doctor or pharmacist. Those who are pregnant, planning pregnancy or breastfeeding should seek professional guidance before use. Always follow the storage and dosage instructions on the label.
