Are Prebiotic Sodas in India Actually Healthy? A Real Test
Share
I sell prebiotic soda. I'm also about to tell you that most prebiotic sodas in India aren't what their label says.
Both are true. Hear me out.
The category started in the US. A few brands proved a fizzy can could carry real fibre, real plant ingredients, and actually leave your gut better than it found it. India watched, copied the format, and quietly re-engineered the inside to hit the same shelf price as a regular cola.
The result is a shelf that looks like the West but doesn't formulate like it.
Yes, ANOTHR is a prebiotic cold drink. Yes, I'm the founder. No, this isn't a "buy us" piece. It's a checklist. Five things to look for on any prebiotic soda in India before you spend on something pretending to be a gut drink.
Use it on us too. If we don't pass, we don't deserve your wallet.
Let's run the test.
Cheat Sheet
TL;DR for the skimmers:
- The category is real. The execution in India is uneven.
- Five label checks before you buy a prebiotic soda: fibre source, caffeine, sweetener, flavour, preservative.
- FSSAI mandates the fibre source on the back panel. Flip the can. If FOS appears, you're paying for the cheap option. Most Indian prebiotic sodas use a FOS-heavy blend with a sliver of chicory inulin added so the brand can claim "contains chicory inulin." Naturally extracted chicory inulin outperforms FOS in head-to-head trials.
- Caffeine in a gut drink is a red flag. It's there for repeat purchases, not your microbiome. A real prebiotic soda has 0mg.
- Real sweetener is monk fruit or stevia. Avoid erythritol. A 2023 Nature Medicine study linked it to roughly 2x higher risk of heart attack and stroke.
- Flavours come in three FSSAI categories. Natural (extracted from the plant) is the cleanest. Nature-identical is the same molecule made in a lab. Artificial is the one to avoid. ANOTHR currently uses natural.
- Real preservative is plant-based. Rosemary extract, not sodium benzoate.
- Run the 5 checks on any can. Including ours.
How prebiotic soda became a category, and what India did with it
A few years ago, Americans started cracking open functional sodas with 7g to 9g of prebiotic fibre per can. Brands like Olipop and Poppi built the blueprint: a cold drink that actually does something on the way down.
The format worked. The market followed.
Then India happened.
The Indian beverage shelf operates on a brutal cost structure. Carbonated cola at ₹40. Energy drink at ₹60. Anything trying to charge more has to keep one foot in that price ceiling or get ignored. So when prebiotic soda became a category here, most new entrants did the math backwards. Start with the price. Work back to the formulation. Cut wherever the consumer can't read the label.
The cuts are predictable. Cheaper fibre. Cheaper sweetener. Cheaper preservative. Cheaper flavour. And one quiet addition that has nothing to do with your gut: caffeine.
Same can shape. Same "prebiotic" badge. Different ingredients inside.
That's the audit.
The 5 Honest Checks
You don't need a chemistry degree. You need a label and 90 seconds.
Check 1: What's the fibre source?
FSSAI mandates that prebiotic fibre sources appear on the back panel. So you don't need to guess. You need to look.
Here's what you'll usually find: FOS, often blended with a small amount of chicory root inulin so the brand can put "contains chicory inulin" on the front. FOS, short for fructo-oligosaccharides, is the cheapest prebiotic input in the category. It's not extracted from a plant the way chicory root inulin is. It's synthesised from sucrose by an enzyme in a factory.
Short chains. Fast fermentation. Cheap. That's the formula.
The performance gap is real. A 2025 randomised controlled trial in BMC Medicine put inulin and FOS head-to-head in 131 adults over 4 weeks. Inulin significantly improved blood-sugar response in overweight and obese participants. FOS did not. Inulin's longer chains (DP ≥10) ferment slowly across the lower colon. FOS's short chains (DP 2 to 9) ferment fast in the upper colon, which is also why FOS-heavy products are more likely to cause gas and bloating.
ANOTHR uses 7g of naturally-extracted chicory root inulin plus PHGG. No FOS. Both fibres come from actual plants.
Flip the can. If FOS is on the label, ask what percentage of the total fibre is FOS. The answer tells you what the brand spent on the inside.
Check 2: Is there caffeine?
This is the cleanest tell in the category. Scan the ingredient list for one word: caffeine. If it's there, the drink isn't built for your gut.
A prebiotic soda is supposed to support your gut. Caffeine raises cortisol. Chronically elevated cortisol weakens the gut lining, shifts bacterial balance, and kills beneficial species like Bifidobacterium. The mechanism is well-documented and we broke it down in the diet soda post.
So why would a "gut health" drink have caffeine?
One reason: repeat purchase. Caffeine creates a mild dependency loop (caffeine withdrawal is recognised in the DSM-5 as a clinical condition). It drives daily consumption. Investors love daily consumption. Your microbiome doesn't.
A real prebiotic soda has 0mg caffeine. ANOTHR uses ashwagandha instead. An adaptogen shown to lower cortisol by 27.9% in clinical trials.
One can wants you to come back. The other wants you to feel better.
Check 3: What's the sweetener?
The sweetener tells you what the brand thinks of your gut.
Three categories worth knowing.
Bad: sucralose, acesulfame-K, aspartame. The artificial sweeteners we broke down in our diet soda post. Linked to gut microbiome damage and glucose intolerance in human trials.
Worse than people realise: erythritol. It's natural-sounding, FSSAI-permitted, zero calorie, and increasingly common in "clean label" Indian functional drinks. It also has a 2023 problem.
A landmark Nature Medicine study by Witkowski et al. tracked over 4,000 adults across the US and Europe. People with the highest erythritol levels in their blood were roughly 2x more likely to have a heart attack or stroke over three years (adjusted hazard ratios of 1.80 and 2.21 across the two validation cohorts). When the team exposed human platelets to erythritol, the platelets became hyper-reactive: they clumped faster, raising clot risk.
The signal showed up in both cohorts. Cleveland Clinic flagged it publicly when their team published the finding.
Better: monk fruit and stevia. Plant-derived, zero calorie, no link to gut microbiome damage in current evidence.
ANOTHR uses monk fruit and stevia. Not because they're cheap. Because they're clean.
Check 4: What's the flavour category?
The flavour line on the back panel tells you which version of "flavour" you're drinking. There are three FSSAI categories, and the difference is real.
Under FSSAI's Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011, every flavoured product must declare its flavour category below the ingredient list. Three options:
- Natural flavour: extracted from the actual plant via essential oil, distillation, or expression.
- Nature-identical flavour: the same molecule as the natural version, made by lab synthesis from a different precursor. Same chemical formula. Different starting point.
- Artificial flavour: synthesised in a lab, doesn't exist in nature at all.
Natural is the cleanest of the three. Nature-identical is the same molecule arrived at a different way, and it's permitted across most Indian beverage categories. Artificial is the one to actually steer clear of.
ANOTHR currently uses natural flavours derived from essential oils. That's the cleaner option when the inputs are workable.
Run the other four checks first. If a can clears those, the flavour line is the smallest variable on the audit.
Check 5: What's the preservative?
A shelf-stable beverage needs a preservative. The question is which one.
The cheap default is sodium benzoate (INS 211). Synthetic. Generally recognised as safe in regulated doses. But when combined with vitamin C and heat (which happens constantly during transport in Indian summers), it can form benzene, a known carcinogen flagged by the FDA in multiple beverage tests.
The plant alternative is rosemary extract. A natural antioxidant that does the same job through carnosic acid. We use it in ANOTHR. The full story is in the rosemary post.
Costs more. Works just as well. Doesn't pretend to be something it isn't.
If the can lists 211 in the ingredients, the brand chose margin over the alternative.
What the test looks like, side by side
| Check | What most labels read | What ANOTHR uses |
|---|---|---|
| Fibre source | FOS as the bulk, with a sliver of chicory inulin added for marketing | 7g chicory root inulin + PHGG. No FOS. Naturally extracted from plants. |
| Caffeine | 30mg+ per can in some entrants | 0mg. Ashwagandha for calm instead. |

Why ANOTHR is more expensive than other Indian prebiotic sodas
A prebiotic cold drink in India costs more than a regular cola when the ingredients inside it cost more, not when the brand wants higher margins.
Every line above costs money.
Naturally extracted chicory inulin is several times the price of synthesised FOS. Rosemary extract costs more than sodium benzoate. Monk fruit costs more than sucralose or erythritol. Adding a full 7g of real prebiotic fibre per can adds cost on every batch. Building without caffeine means accepting lower repeat-purchase rates than a stimulant-driven SKU.
These aren't margins. They're inputs.
If a prebiotic soda is hitting the same shelf price as a regular cola, the formulation got cheapened somewhere. There is no third option.
We priced ANOTHR for the formulation, not the unit economics a deck demanded. The number on the can is what the can actually costs to make. The cheaper alternatives exist. We've been pitched them. We said no on the ones that matter most.
You don't have to take our word for it. Flip any can, run the 5 checks, do the math yourself.
Why this brand exists
ANOTHR exists because India didn't have a healthy cold drink that actually worked on gut health, and the founder needed one.
Quick bit of context, since I'm the one writing this.
I'm Naman, founder of ANOTHR. The reason this brand exists is gut health. Mine specifically.
A few years ago I was living in a hill station, working remotely, surviving on cafés and diet colas. My gut declared a war it eventually won. Months of bloating, stomach aches, the works. A trip to Singapore introduced me to prebiotic sodas. Fizzy, fun, and actually doing something. I came back asking why India didn't have this.
Building ANOTHR wasn't a business idea waiting for a category. It was the drink I needed to exist. Every cut corner I'm calling out in this post is a corner I refused to cut when I was the person who'd have to drink it.
If you want the full founder version, the pillar post goes deeper.
FAQs
Are prebiotic sodas actually healthy?
Prebiotic sodas can be a real gut-health upgrade over regular soda, but only if the formulation matches the label. A good prebiotic cold drink has at least 5g of naturally-extracted plant fibre per can, no artificial sweeteners or erythritol, natural flavours, a plant-based preservative, and zero caffeine. If a label fails any of those checks, it's a regular cold drink in better marketing.
What should I look for in a prebiotic soda in India?
Five things to scan on the back panel. A named plant fibre source like chicory root inulin or PHGG (avoid FOS-heavy blends). Zero caffeine. A natural sweetener like monk fruit or stevia. Ideally a natural flavour over nature-identical or artificial. And a plant-based preservative like rosemary extract.
Is FOS a real prebiotic?
Technically yes, but it's the cheapest fibre input in the category. FOS is synthesised from sucrose in a factory, not extracted from a plant. Its short chains ferment fast in the upper colon, which is why FOS-heavy products are more likely to cause gas and bloating. A 2025 BMC Medicine trial also showed naturally-extracted chicory inulin significantly outperformed FOS on blood-sugar response.
Is erythritol safe in prebiotic sodas?
Recent evidence raises real concerns. A 2023 study in Nature Medicine tracked over 4,000 adults and found that people with the highest blood erythritol levels were roughly 2x more likely to have a heart attack or stroke over three years. The proposed mechanism is increased platelet reactivity, which raises clot risk. Monk fruit and stevia are safer choices.
Why is ANOTHR more expensive than other Indian prebiotic sodas?
ANOTHR uses naturally-extracted chicory root inulin, monk fruit, natural flavours from essential oils, and rosemary extract as a preservative. Each of those is several times more expensive than the cheaper alternatives most Indian prebiotic sodas use. The price difference is the formulation, not the margin.
