Probiotic soda is a carbonated drink that contains added live probiotics. It keeps the fruit flavour, sweetness and refreshing fizz people expect from soda, but adds measured probiotic cultures to make the drink more functional.
It is designed for people who enjoy sparkling soft drinks but want an option with probiotics and a lighter nutritional profile.
Relow is a sparkling probiotic soda made with 1 billion+ CFU of Bacillus subtilis per can. It has zero sugar, zero caffeine and low calories, and is sweetened with naturally extracted stevia. It is available in Lemon, Mango and Orange flavours.
If you have heard the term but are still wondering what is probiotic soda, this guide explains its meaning, ingredients, potential benefits, CFU count, storage and how Relow works.
Quick Answer: What Is Probiotic Soda?
Probiotic soda is a fizzy beverage containing added live microorganisms known as probiotics. These probiotics are included in a measured quantity, normally shown as CFU or colony-forming units.
Relow is a zero-sugar probiotic soda containing 1 billion+ CFU of Bacillus subtilis in every 250 ml can. It combines probiotics with carbonation, natural fruit flavours, real fruit juice and naturally extracted stevia.
Probiotic soda is a beverage, not a medicine. It should be enjoyed as part of a balanced diet and should not be used to prevent or treat a digestive condition.
What Does Probiotic Soda Mean?
The meaning of probiotic soda becomes easier to understand when you separate the two words.
“Probiotic” refers to live microorganisms that may provide a health benefit when consumed in an adequate amount.
“Soda” refers to the carbonated format of the drink. It provides the bubbles, refreshing mouthfeel and familiar experience associated with a fizzy soft drink.
Put the two together and probiotic soda means a carbonated beverage containing a measured amount of live probiotics.
The probiotic is what gives the drink its functional element. The carbonation, fruit flavour and sweetness make it feel familiar and enjoyable.
Relow was created around this balance. It provides a proper sparkling soda experience while including 1 billion+ CFU of probiotics in every can.
What Is Relow Probiotic Soda?
Relow is a sparkling probiotic soda created for people who love fizz but want to reduce sugar, caffeine and unnecessary calories.
Each can contains:
-
1 billion+ CFU of probiotics
-
Bacillus subtilis
-
Zero sugar
-
Zero caffeine
-
Low calories
-
Naturally extracted stevia
-
Real fruit juice

You can find all three options in the official Relow probiotic soda shop.
How Does Probiotic Soda Work?
Probiotic soda works by adding a measured probiotic culture to a carbonated drink.
In Relow, the probiotic is Bacillus subtilis. Every can contains 1 billion+ CFU, giving consumers a clear indication of the probiotic quantity in one serving.
The complete process can be understood in four simple parts.
1. A Carbonated Drink Base Is Created
Carbonation gives probiotic soda its fizz. It creates the crisp, bubbly texture that separates soda from still juice, flavoured water or other non-carbonated drinks.
For many people, carbonation is an important part of the experience. They are not necessarily craving sugar alone. They also want the cold, sparkling sensation of opening and drinking a fizzy beverage.
2. Fruit Flavour Is Added
Relow uses familiar Lemon, Mango and Orange flavours.
These flavours allow people to begin with a taste they already know. Lemon provides a zesty and refreshing experience, Mango is more tropical and fruit-forward, while Orange offers a tangy citrus profile.
3. The Drink Is Sweetened Without Sugar
Relow contains zero sugar and uses naturally extracted stevia to provide sweetness.
Stevia is derived from the stevia plant and allows the drink to taste sweet without using conventional sugar. Relow also states that it does not use sucralose or aspartame.
This is an important part of the formulation because many people are interested in probiotic soda as a replacement for sugar-heavy fizzy drinks.
4. Probiotics Are Included
The functional element comes from the added probiotic.
Relow uses Bacillus subtilis, a shelf-stable probiotic. This allows unopened cans to be stored without refrigeration when the storage instructions on the packaging are followed.
The probiotic quantity is expressed as CFU. Relow provides 1 billion+ CFU in every can.
What Does CFU Mean in Probiotic Soda?
CFU stands for colony-forming units. It is a way of expressing the estimated number of viable microorganisms in a probiotic product.
You may see probiotic quantities written as:
-
100 million CFU
-
1 billion CFU
-
1×1091 \times 10^91×109 CFU
-
10 billion CFU
-
1×10101 \times 10^{10}1×1010 CFU
The expression 1×1091 \times 10^91×109 means 1 billion CFU.
Relow states that every 250 ml can contains 1 billion+ CFU of Bacillus subtilis.
A higher CFU number is not automatically better. The identity of the probiotic, the amount used, its viability throughout the product’s shelf life and the complete formulation all matter.
Consumers should therefore look for a clearly stated probiotic organism and CFU count instead of choosing a product only because it uses the word “probiotic.”
What Are the Ingredients in Probiotic Soda?
The ingredients vary between products, but a probiotic soda generally combines a carbonated beverage base, flavour, sweetener and probiotic culture.
Relow’s formulation is built around:
-
Carbonation
-
Real fruit juice
-
Natural ingredients
-
Lemon, Mango or Orange flavour
-
Naturally extracted stevia
-
Bacillus subtilis
-
1 billion+ CFU per can
Relow also highlights what it does not contain:
-
No sugar
-
No caffeine
-
No sucralose
-
No aspartame
-
No preservatives
-
No artificial flavours
Reading the complete ingredient list is important because the word “probiotic” alone does not explain the nutritional profile of a drink. Probiotics can be present in a beverage that also contains sugar, caffeine or a sweetener you may not prefer.
Relow makes its key product information clear so buyers can understand what they are choosing.
What Are the Potential Benefits of Probiotic Soda?
The benefits of Relow probiotic soda can be divided into two areas: its probiotic content and its role as a zero-sugar alternative to conventional fizzy drinks.
It Provides Probiotics in a Convenient Format
Relow delivers 1 billion+ CFU of probiotics in a ready-to-drink can.
You do not need to mix a powder, take a capsule or prepare a special drink. You can open the can and enjoy it chilled with a meal, snack or during an afternoon break.
This convenience can make probiotics easier to include in an existing routine.
It May Support Gut Health as Part of a Balanced Diet
Probiotics are live microorganisms that may support aspects of gut health when the appropriate microorganism is consumed in an adequate amount.
However, Relow should not be presented as a cure for bloating, acidity, constipation or another digestive condition. A single drink cannot replace the wider factors that influence digestive health, including:
-
A varied diet
-
Fibre-rich foods
-
Fruits and vegetables
-
Sufficient water
-
Regular meals
-
Sleep
-
Physical activity
-
Individual medical care

It Helps You Reduce Sugary Soft Drinks
Relow contains zero sugar. This makes it useful for people who want to reduce the amount of sugar they consume through fizzy beverages.
The product keeps the carbonation and fruit flavours people associate with soda, which can make the change feel less restrictive.
You do not have to move directly from regular soft drinks to plain water every time. Relow gives you another option when you specifically want flavour and fizz.
Read probiotic soda vs regular soda for a more detailed explanation of the differences.
It Is Low in Calories
Relow is designed to be low in calories.
This is relevant because calories consumed through drinks can be easy to overlook. Choosing a low-calorie fizzy drink may help reduce the calories obtained from beverages without removing the soda experience entirely.
Low calorie does not mean the drink should replace food or water. It simply describes one part of its nutritional profile.
It Contains Zero Caffeine
Relow contains no caffeine.
This makes it suitable for people who enjoy soda with dinner or later in the day but prefer to avoid caffeine. It can also be useful for people who already consume caffeine through coffee or tea and do not want to add more through their soft drink.
It Is Shelf-Stable
Relow uses shelf-stable Bacillus subtilis.
Unopened cans do not require refrigeration, which makes them convenient for:
-
Home storage
-
Office pantries
-
Travel
-
Events
-
Parties
-
Restaurant-style meals at home
The cans should still be stored in a cool, dry place away from direct sunlight and excessive heat, following the instructions printed on the packaging.
It Offers Familiar Fruit Flavours
A functional drink still needs to taste enjoyable if it is going to become part of someone’s routine.
Relow is available in Lemon, Mango and Orange. These familiar flavours make the experience accessible to people who already enjoy fruit-flavoured sodas.
Is Probiotic Soda the Same as Prebiotic Soda?
No. Probiotic and prebiotic soda are not the same.
Probiotic soda contains live microorganisms. Relow contains live Bacillus subtilis probiotics in a measured CFU amount.
A prebiotic drink contains a substrate, often a type of fibre, that is used by certain microorganisms already present in the body.
Some beverages may contain both probiotics and prebiotics, but the two terms should not be used interchangeably.
Relow is specifically a probiotic soda because it directly contains 1 billion+ CFU of probiotics per can.
Is Probiotic Soda Fermented?
Not every probiotic soda is a fermented drink.
Relow is formulated as a sparkling soda with added probiotics. It is designed to provide familiar fruit flavours and carbonation without an intensely fermented or vinegary taste.
This is an important distinction for people who want probiotics but prefer their drink to taste like a refreshing fruit soda.

What Does Relow Probiotic Soda Taste Like?
Relow is made to taste fruity, light and sparkling rather than thick, syrupy or medicinal.
Relow Lemon
Relow Lemon has a zesty citrus profile. It pairs particularly well with spicy food, savoury snacks, fried dishes and everyday meals.
It can also be served over ice with mint, cucumber or lime.
Relow Mango
Relow Mango provides a tropical and fruit-forward taste.
It is a sparkling soda, not a thick mango shake or nectar. Its lighter format works well with Indian meals, grilled food, wraps, burgers and spicy snacks.
Relow Orange
Relow Orange offers a tangy citrus flavour inspired by familiar orange soda.
It can be served with pizza, burgers, sandwiches, grilled dishes, party snacks and Indian meals. You can also pour it over ice and add a fresh orange slice or mint.
Which Relow Pack Should First-Time Buyers Choose?
The Relow Variety Pack is the most practical choice for first-time buyers.
It includes:
-
Two Lemon cans
-
Two Mango cans
-
Two Orange cans
This gives you an opportunity to try all three flavours before choosing a full pack of one.
If you already know your preferred flavour, select an individual Lemon, Mango or Orange pack. Regular customers, households and offices can choose The Relow Case of 24, which is available in single-flavour and variety options.
When Should You Drink Probiotic Soda?
There is no single compulsory time to drink Relow.
You can enjoy it:
-
With lunch
-
With dinner
-
With an afternoon snack
-
During a work break
-
With takeaway food
-
At a party or gathering
-
When you are craving something fizzy
-
As the base for a simple alcohol-free mocktail
Many people prefer a probiotic drink with or around a meal because it fits naturally into their routine. Personal comfort and consistency are more useful than searching for one perfect time.
Read our guide to the best time to drink probiotic soda for more practical guidance.
Can You Drink Probiotic Soda Every Day?

Water

Whole fruits

Vegetables
-
Fibre-rich foods
-
Balanced meals
-
Medical treatment
-
