Best probiotic overall in the UK
YourBiology Gut+ probiotic
YourBiology Gut+ is a premium gut supplement with various ingredients beyond just probiotics to improve gut health and general health. It is aimed at women, however anyone can take it. (If you’d prefer a product aimed at men, Biotics 8 is a very similar product from the same company.)
This supplement contains 10 strains of probiotics to give you a good amount of microbial diversity.
The strains and their benefits are:
Lactobacillus acidophilus – Supports digestion and helps maintain vaginal and intestinal health.
Lactobacillus casei – Aids lactose digestion and supports immune function.
Lactobacillus paracasei – Helps reduce inflammation and supports gut barrier integrity.
Lactobacillus rhamnosus – Known for preventing diarrhoea and supporting immune health.
Lactobacillus plantarum – Promotes gut healing and helps reduce bloating and gas.
Lactobacillus fermentum – Offers antioxidant benefits and supports respiratory health.
Bifidobacterium longum – Helps balance gut flora and reduce gastrointestinal discomfort.
Bifidobacterium bifidum – Aids in breaking down food and absorbing nutrients.
Bifidobacterium breve – Supports skin and gut health.
Saccharomyces boulardii – A probiotic yeast that helps prevent antibiotic-associated diarrhoea and supports gut lining repair.
Collectively, these strains provide 20 billion colony forming units per three-capsule serving.
As as key point of difference to many other brands, it also contains prebiotics, digestive enzymes and vitamin D which collectively provide a more holistic approach to gut health than just probiotics alone.
Prebiotics are essentially fibres which promote the growth of probiotics (ie beneficial microbes) in the gut. This supplement contains two types of prebiotic fibre in the form of inulin and fructooligosaccharides (commonly known as FOS).
YourBiology Gut+ also includes three digestive enzymes - lipase, amylase and protease. These enzymes reduce the digestive burden on your gut which allows probiotics to more effectively colonise the gut and support gut repair.
This supplement also provides vitamin D which helps create a healthier, less inflamed environment where probiotics and digestive processes can function optimally.
This supplement is suitable for vegans.

Covering more bases
One thing I admire about YourBiology is that it is a multifaceted product which covers various aspects of gut health. This means that it is more likely to be of benefit to you than most other brands.
Various factors can cause gut issues and often it isn’t immediately clear what those are. Since YourBiology includes probiotics, prebiotics, digestive enzymes and vitamin D it is more likely to be of benefit to you than a product with only probiotics - because probiotics might not be the solution to your issues.
Money-back guarantee
Another big selling point of YourBiology Gut+ is that they offer a 60-day money-back guarantee if you’re not satisfied.
This kind of full-refund guarantee is not common among probiotics.
And in my opinion this risk-free offer makes YourBiology something really worth trying at least to see if it helps you.
Dosing
The dosing guidelines say to slowly increase the daily intake from 1 to 3 capsules to give your gut time to adjust.
Cost and availability
YourBiology Gut+ is more expensive than many other probiotics because it is a premium and multi-faceted gut health product which also includes prebiotics, digestive enzymes and vitamin D.
Prices vary so it’s best to check their website for current offers. And they offer a 15% discount on subscriptions.
It is not available in supermarkets or chemists.
Summary
Rating: 4.75 stars out of 5.
Verdict: YourBiology Gut+ not only offers 10 strains of probiotics, but also includes two types of prebiotics, three digestive enzymes and vitamin D for gut health support. All this means it offers a lot more benefits for gut health and general health than most probiotic supplements do. However, as you might expect, this comes at a premium price.

Best probiotic with a strong evidence base
Symprove
Symprove is a great choice for those wanting a probiotic with strong scientific research supporting it.
Symprove is a water-based probiotic that describes itself as science-led and has been supported by independent studies from King’s College London and University College London.
A key selling point of Symprove is that it is designed to survive your acidic stomach and reach your gut alive. This is achieved by selecting specific strains of common probiotic species which are proven to survive stomach acid. It is also achieved because Symprove is water based which means it doesn’t trigger digestion which might kill the healthy microbes.
You can read more about the research done into Symprove in our full review.
Symprove contains four strains of probiotics:
Lacticaseibacillus rhamnosus NCIMB 30174
Enterococcus faecium NCIMB 30176
Lactobacillus acidophilus NCIMB 30175
Lactiplantibacillus plantarum NCIMB 30173
Each shot gives you 10 billion colony forming units of probiotics.
It is gluten-free, dairy-free and suitable for vegans.
Dosing
It is taken as a 70ml shot 10 minutes before breakfast.
Cost and availability
Symprove is available through their website.
On a subscription basis it costs £49.99 per month, or £79.99 as a one-off 4-week purchase.
However, you can get 50% off the first three months using the discount code HELLOGUT50 at symprove.com.
Summary
Rating: 4.75 stars out of 5.

Best gut health test in the UK
Healthpath Ultimate Package
The Healthpath Ultimate Package is a great choice for those who want more than just a gut health test and want expert support and guidance also.
What the test covers
The test itself is remarkably comprehensive. Healthpath claims to have the most comprehensive test in the UK which measures over 100 biomarkers.
Along with testing your microbiome composition of bacteria, fungi and yeasts very extensively (covering 61 species), the test also:
checks if you have leaky gut
checks your immune response and inflammatory markers
sees if your digestion is working well
analyses parasites
includes early bowel cancer detection
analyses archaea
analyses histamine, butyrate and hydrogen-sulphide-producing bacteria
Further support in the package
In contrast to other tests, your journey with Healthpath doesn’t end after receiving the report. There is a vast amount of support and guidance yet to come.
In the package you will get:
a practitioner review of your test results and a personal video from them to explain the results
a bespoke health plan. This is 12-week health plan based on your symptoms and results
a personalised supplement plan in which a practitioner will select the best supplements to support your individual gut health
a meal plan which includes shopping lists and recipes
a symptom review in which a practitioner will review your symptom survey to ensure your health plan, supplement recommendations and analysis are tailored to you
a health coaching call which is a 30-minute personal consultation with an experienced practitioner. This allows you to talk through your results, get 1-to-1 support and discuss next steps
As you can see, the amount of individual support offered is incredible and will leave you with all your questions answered and a path forward guided by experts.
Cost

Best superfood supplement
YourBiology SuperGreens+
YourBiology SuperGreens+ is a superfood greens powder supplement which you add to water.
It contains a huge array of vitamins, minerals, amino acids, polyphenols, antioxidants and fibre. These nutrients are specifically focused on supporting digestion, immunity, energy, mental clarity and skin health.
See our full review for a full list of ingredients and their health benefits.
This supplement makes it very easy to get a daily dose of vital nutrients.
Dosing
The dosing guidelines are to take one scoop with 200-300ml of water. You can also add a scoop to smoothies or mix with food.
Flavour
The aroma is mostly of green tea with seaweed characteristics.
The taste is minty and of green tea predominantly. It is also fairly sweet from the stevia. It is surprisingly easy to drink considering I was expecting it to taste like green sludge ¯\_(ツ)_/¯
Overall, it’s easy to take, the taste is good, but I wouldn’t want it any more sweet.
Cost and availability
YourBiology SuperGreens is a premium, broad spectrum supplement which offers a huge amount of nutrition and health benefits, so I wouldn’t expect it to be cheap.
Prices vary from country to country so it’s best to check their website for current offers.

Rating: 4.5 stars out of 5.
Verdict: YourBiology SuperGreens makes it very easy to get a huge amount of nutrition in one glass. Great for supporting gut health, skin health, energy and immunity.

Factors we consider in our ratings
The factors we consider when doing a review (and the weightings of each of these) may vary depending on the product we are testing, but here are the key general factors we consider when we settle on a rating for a product.
Health benefits
We find out how the product will be good for your health and outline the benefits for you in simple language. This often involves doing research so you don’t have to. We often link to scientific studies or articles summarising scientific findings so you can dig deeper if you want to.
Things detrimental to health
We want to highlight where a product might include something bad for your health - even if it might be good for you in another way. This could include such things as pointing out certain additives it contains or high sugar levels.
How it’s made
This will vary depending on the product, but we want to see a quality process for making it and quality ingredients. For example, we want to see a kombucha traditionally fermented with lots of different microbial strains and we want to see a yoghurt made with fresh milk and not milk powders.
Price
While we expect quality products to be more expensive, they still have to be priced within reason. On the other side of things, a product which is priced very competitively will get a ratings boost based on the value it provides.
Flavour
For some products flavour won’t be a factor (eg probiotic tablets), but for others, like yoghurt or kimchi, flavour is a key aspect because these products are made to be enjoyed as well as being healthy! We will try to be as subjective as possible and describe the flavour in detail so you can get an idea of whether you would like it or not.
