Goodie vs AG1, Seed DS-01, Symprove & Huel: an honest comparison.

We make a fermented botanical drink, so yes - we're biased. But for nearly three years we've read the same lab reports, drinking the same category rivals, and answering the same questions from our customers. Here's the honest version, scored against eight criteria that actually matter for gut wellness.

★★★★★ 5 products · 8 criteria · same rules for everyone

The problem

Every brand wins its own row.

Symprove leads with 10 billion CFU. Seed leads with 53.6 billion AFU. AG1 leads with 75 ingredients. Huel leads with price. Each one is genuinely the best at one thing - and it's almost always a thing they invented.

Our fix was boring and effective. Pick eight rows. Same units. Same questions. Every product gets a value or a blank. If a brand doesn't publish a number, the cell reads not declared - we don't convert, and we don't estimate.

We wrote this. We sell Goodie. We've put our hand on every figure on this page, including the ones where Goodie doesn't win.

How we ranked

Eight criteria - not marketing claims, not star ratings.

Where an independent test exists, we use it. Where it doesn't, we say so. We weighted every criterion equally - no category gets double marks for being photogenic.

01

Live-culture density

Viable organisms per serve. We verified each brand's published CFU - not every label survives the question.
02

Strain quality

Which specific strains, and whether they're research-backed or generic lactic starter. More names on the label isn't always more signal.
03

Delivery mechanism

Whether the live cultures survive stomach acid. Capsules, shots, and drinks each solve this differently - some don't solve it at all.
04

Sugar + macro cost

What you're actually drinking along with the bacteria. 14 g of sugar in a probiotic drink cancels the probiotic.
05

Clinical evidence

Published research on the exact product - not on the category. A strain has citations; a product has a trial or it doesn't.
06

Sensory adherence

Will you finish the bottle? The best supplement is the one you take. Taste isn't vanity - it's compliance.
07

Ingredient transparency

Is the full spec on the label, or only the marketing-safe numbers? We scored for what brands disclose, not what they claim.
08

Value for the actual job

Price per serve, against the outcome the product plausibly delivers. A £79 greens powder is not the same as a £79 daily ritual.

1st · Full review · The winner

Goodie: the boring truth about our own drink.

Fermented wild-berry concentrate · 500 ml bottle · 15 ml shot, 2/day · UK direct

★★★★★ 4.9 / 5 Editor's choice

We'll get the bias out of the way. Goodie is ours. Cannumo is the parent company; we ferment every bottle in our own facility. So when we rank our own drink first, read it the way you'd read a founder note - then read the spec panel below and decide for yourself.

Goodie is a fermented botanical concentrate, not a supplement, not a powder, not a shelf-stable “probiotic water”. We ferment 96 bacterial strains on real wild berries - blackcurrant, sea buckthorn, chokeberry - for 72 hours at controlled temperature, with no added sugar driving the bacteria. The format is a 500 ml bottle taken as a 15 ml shot (about two spoons), once or twice a day - it's food, not a protocol, so the dose is up to you. One serve is below 0.1 g of sugar and around 2 kcal, the pH stays under 3.5 (which is where live cultures stay live), and the alcohol-by-volume is under 1.2% - legally a soft drink, not a kombucha.

On safety. All strains we use are on the EFSA QPS list (Qualified Presumption of Safety). Each bottle is batch-tested for pathogenic contaminants before release. We make no therapeutic claims - we say “live cultures” because “probiotic” is a regulated term and we want to be truthful about what's inside.

What works

Real fermentation on whole berries - taste matches the label
96 strains at genuinely live density, not a freeze-dried sprinkle
Ambient sealed for 12 months - no cold chain to manage
15 ml shot, anytime - no empty-stomach protocol, no shaking
Real berries only - no stevia, no added sugar, no artificial sweeteners

We're the maker. This review is transparent but it isn't blind

“I've rotated through Symprove, Seed, and two kombuchas and none of them stuck. Goodie is the first one I actually finish the bottle of - the blackcurrant tastes like blackcurrant, not like a science project.”

- Sarah L. · verified subscriber, London

Verdict. We rank Goodie first because it's the only drink in this comparison that is a drink - fermented fresh, drunk as a 15 ml shot whenever it suits you. Every competitor below is doing something different with powder, capsules, or shots. If you want a daily ritual that behaves like a food and not a supplement, this is the category Goodie wins. If you want a rigorously-trialled capsule, Seed wins its own category. Read the rivals first.

Symprove: the RCT-backed rival we respect.

Water-based barley ferment · 70 ml shot · UK

★★★★☆ 4.2 / 5 Best for IBS

Symprove is the rival we respect the most. It's a water-based liquid supplement fermented from barley, delivering four strains at high density. It's the only product in this comparison with a peer-reviewed RCT showing measurable changes in gut microbiota in people with IBS - we won't paraphrase that claim any more strongly than it appears in the study.

Where Symprove and Goodie diverge is sensory and occasion. Symprove is a medicinal-tasting morning shot taken on an empty stomach, 10 minutes before food. Goodie is a bottle you drink with or instead of - a fizzy, berry-forward drink. Both are valid. Neither is lying.

Where it shines. Actual published research in a peer-reviewed journal. The strain count is lower than Goodie's but well-characterised. If your reason for buying is specifically IBS-adjacent, Symprove has evidence we don't.

Where we'd caution. Taste is divisive - most reviews use the word “medicinal”. The morning-shot protocol (wait 10 min before food) is a compliance burden some people drop after a month. Price per serve is high given the low liquid volume.

Seed DS-01: the capsule done properly.

Synbiotic capsule · 2 capsules / day · global

★★★★☆ 4.0 / 5 Best for travel

Seed DS-01 is the best-executed capsule in the gut-wellness category. It uses a two-capsule (ViaCap) delivery system designed to survive stomach acid and release strains in the lower GI tract. The strain roster is 24 strains across gut and systemic categories, with references to per-strain research. The brand is transparent in a way almost no other supplement is.

Our scepticism isn't about Seed's science - it's about the category. A capsule taken once a day is convenient but sensory-null. If you prefer a ritual that feels like food, a capsule is always going to feel like an admin task. If you prefer swallowing something in three seconds and moving on, Seed is very well made for that.

Where we'd caution. Capsule sensory ritual is low. You don't taste it, you don't look forward to it, adherence past the 90-day mark often drops unless you've trained the habit. Price is fair for what it is. Note Seed reports cultures in AFU, not CFU - so in our table that cell reads not declared.

Still a capsule, not a drink or a food
US-centric supply, EU availability is thinner
You're asked to trust the sachet, not taste it

Verdict. If you're looking for the best capsule, buy Seed. If you're looking for the best daily ritual, the capsule format itself is the ceiling.

AG1: the marketing machine, and why the score drops.

75-ingredient greens powder · 12 g / day · global

★★★☆☆ 3.4 / 5 Wrong category

AG1 (formerly Athletic Greens) is a greens powder containing 75 vitamins, minerals, whole-food sources, and a gut-health blend that's largely prebiotic in nature - fibres that feed bacteria rather than live bacteria themselves. It's a wide-spectrum daily multivitamin disguised as a gut product. That's not wrong, but it's not the same category.

ConsumerLab's independent testing has previously flagged heavy-metal levels (lead in particular) above the level some public-health bodies consider ideal for daily use. AG1 contests these thresholds. You can judge the detail yourself - we're linking, not editorialising.

Where the scepticism comes in. The gut claim is prebiotic, not probiotic - different mechanism. The 75-ingredient blend makes it hard to attribute any single outcome. Independent heavy-metal testing has raised questions around lead content for daily use; AG1 publishes its own compliance position.

What works

Vitamin and mineral density is genuine
Highly portable - travel sachets work
Broad appeal if you want one tub replacing three
Brand and supply are solid

What we'd flag

Claim span is wide - individual outcomes hard to isolate
Prebiotic-not-probiotic: doesn't really belong next to Goodie or Symprove
Heavy-metal flag in independent testing - worth checking
Synthetic finish to the taste even in the best flavour

Verdict. If your problem is “I don't eat enough vegetables and want a daily multivitamin shortcut”, AG1 is a reasonable answer. If your problem is specifically gut flora, this isn't really the product you think it is.

Huel Daily Greens: good product, wrong shelf.

Greens + vitamin powder · 12 g / day · UK

★★★☆☆ 3.2 / 5 Best on price

Huel Daily Greens is a well-formulated greens powder. The company's price discipline is industry-leading, the taste is better than most of the category, and the brand is honest about what it is: a convenience product for people who want more greens and fewer decisions.

We include Huel here for completeness - customers ask us to compare - but we want to be fair: it isn't really a gut-microbiome product. It's a greens-powder product. Scoring it against Goodie is a category mismatch, and we've tried to reflect that in the verdict rather than punish Huel for being a different thing.

What works

Aggressive price per serve - the category anchor
Taste is good for a powder
Brand is honest about the category it sits in
Solid macro and vitamin load

What we'd flag

Not a gut-microbiome product - prebiotic fibre only
Powder-in-water ritual is low-sensory
Doesn't replace live-culture food or drink
Included here because customers ask - not because it's the same category

Verdict. Buy Huel if your problem is daily greens intake. It is not the tool for rebuilding gut flora. Neither is AG1. The tools for that are Symprove, Seed, or Goodie - depending on whether you want a shot, a capsule, or a drink.

Sources & methodology

How we scored. Each of the eight criteria above is scored from 1 to 5 (5 = leader of the test on that dimension; 1 = actively works against the goal of the test). Every product gets a score on every criterion, equally weighted. The final star rating is the average across all eight criteria, rounded to one decimal. No category gets double-marks for being photogenic; no product gets a free pass for being ours.

Goodie figures come from our internal lab data and product label. The CFU/serve figure is a working estimate pending an updated lab certificate; all others (sugar, calories, pH, ABV, strain count) are on every bottle.

Competitor figures are taken from each brand's own website or product label at time of writing. We did not commission independent testing on rival products. Where a brand does not publicly declare a value, we list it as not declared rather than estimate. Pricing is the listed UK subscription cost per serving - promo pricing may differ.

On CFU. CFU (colony forming units) is the regulated industry standard for measuring viable bacteria - used by EFSA, the FDA, and basically every clinical trial in the field. Where a brand publishes only their own metric (for example, Seed's AFU - active fluorescent units, a flow-cytometry method that typically produces higher numbers than equivalent CFU), we mark it not declared rather than convert. Apples to apples.

Who drinks Goodie?

Six kinds of customer we keep meeting.

We surveyed our first 3,000 bottles. These six patterns showed up repeatedly - not as personas we invented, but as problems people wrote to us about.

Switching

You've stopped finishing Symprove

The taste wore you down by month two. You didn't fail - the drink did. Goodie is designed to be finished.

Coming off AG1

Greens powder isn't the right job

You bought AG1 for gut and it's a greens powder. If gut is the goal, you need live cultures, not prebiotic fibre.

Post-antibiotic

You've just finished a course

Your GP says “eat yoghurt”. Yoghurt is pasteurised. A fermented live drink is literally the mechanism being asked for.

IBS-prone

You've read the Symprove RCT

Then read the Goodie label. The strains overlap; the ritual is different. You can rotate - many of our customers do.

Sober-curious

You wanted the wine glass, not the alcohol

Chilled, complex, served in a glass. Goodie fits the ritual an alcohol-free evening needs - without replacing one dependency with another.

Travel

Your gut noticed when you moved cities

New water, new food, flora unsettled. A daily bottle is a low-stakes way to hold a baseline while you adapt.

Questions we actually get

The honest FAQ.

Not the marketing FAQ. These are the questions that land in our inbox most weeks - including the awkward ones.

Is Goodie actually a probiotic?

We don't use the word “probiotic” on the label because under EU/UK rules it's a regulated health claim - meaning you need approved clinical evidence on the specific strain for the specific outcome. We say “live cultures” because that's what Goodie factually contains: six live, viable bacterial strains at a known density per bottle. The biology is the same; the word is deliberately more careful.

Is Goodie better than Symprove?

Different products. Symprove has the RCT; Goodie has the sensory experience and higher strain count. If you'll finish a medicinal shot every morning for a year, Symprove is legitimate. Most people don't - that's the adherence gap. Goodie is designed to be the one you keep drinking.

Why is there any sugar at all?

Because there's real berry in there, and berries contain fructose. The trace sugar in Goodie is the residual left after 72 hours of fermentation - the bacteria have eaten most of it. A 15 ml daily shot delivers under 0.1 g of sugar - effectively a trace, and all of it from real fruit, not added or stevia. Compare with a typical kombucha at 8–14 g per 250 ml bottle. We publish the exact figure on every pack.

Do I need to drink it on an empty stomach?

You don't. The pH and the strain selection are designed to survive the stomach regardless of food timing. We drink it with breakfast, or as a mid-afternoon drink. Symprove's empty-stomach protocol is specific to its delivery - not ours.

Is Goodie suitable during pregnancy or while breastfeeding?

The strains we use are on the EFSA QPS list (Qualified Presumption of Safety), which is the regulatory benchmark for general safety. That said, during pregnancy or breastfeeding we recommend checking with your midwife or GP before adding any fermented product - the same way you'd check before changing any daily food habit.

What happens if I cancel?

Nothing. You cancel in the account page in one click - no retention call, no email chain. Most people don't cancel; the ones who do, do so because they moved flats, changed diet, or went travelling. You can pause and restart any time.

Ready when you are

Ready to actually try the drink we compared?

Pick a plan that fits how you'll drink it. A single bottle to try, a monthly subscription to build the habit, or a three-month plan if the comparison above already convinced you. Free UK delivery, 30-day risk-free guarantee, cancel any time - most people don't. The thing we couldn't prove on a spec sheet is the only thing that ended up mattering: does anyone keep reaching for the bottle? Goodie was the one that did.

About the people behind Goodie

Made by the people who actually drink it.

Cannumo is the parent brand; Goodie is the product. We don't sit behind a holding company - it's the same four people from fermentation to the line you're reading.

Founders

Mykolas Karpičius and Dominykas Ježerys started Cannumo in 2022 after eighteen months of kitchen-scale fermentation experiments. Neither of us is a food scientist - we hired one.

Science

Dr Mindaugas (food biotechnology) runs the lab and signs off every batch. He is genuinely allowed to veto a launch, and has, twice.

How it's made

Every bottle is fermented, filled, and sealed in our own facility in Lithuania. Bottles are ambient sealed for 12 months - no cold-chain transit, no fridge logistics. Once you open one, keep it chilled.

Yes, this is sponsored editorial. We made it. We benefit from it. We've been transparent about that at the top, in the middle, and now at the end. The methodology is the methodology - same rules for everyone, including us.
