Tried everything. Felt nothing?
The problem
The cupboard keeps filling up.
Powders, capsules, greens, probiotics. More bottles every month, more to remember, and you still do not feel any different.
The reality
Most of it has a journey to survive.
Live bacteria have to get through your stomach and settle in your gut before they can make anything useful. That is a lot to ask of a capsule.
The solution
Postbiotics skip that journey.
AYA BIOME™ Fermented Turmeric is fermented before it reaches you, so nothing has to survive.
Alastair JesselFounder, The Postbiotic Company
What is a postbiotic?
- PrebioticFood for the bacteria in your gut.
- ProbioticLive bacteria, which have to arrive alive.
- PostbioticWhat the bacteria make during fermentation. Already made, ready to take.
As the owner of Battersea Park Clinic, an integrative wellness centre in London, my vision is simple: to turn what research is revealing about the gut microbiome into products and information people can actually trust.
Every week people come through the clinic doors who are ill, with symptoms that pharmaceutical products usually mask but never treat at the root cause. Working alongside our clinicians and nutritionists has taught me that quick fixes don't work. The gut keeps coming up as one of the areas conventional medicine understands least.
In 2024 I came across postbiotics, a new area of science. I started taking them myself. The results were spectacular. I flew to the USA several times to arrange a deal that would bring them to Europe. A year later the business was sold to a Norwegian company. My deal went down the drain.
But the search led me somewhere better. The same Japanese researchers behind that original product had developed a fermented turmeric: Bhutanese turmeric, fermented with a specific, deposited strain of Lactobacillus acidophilus. Fermentation changes what turmeric becomes. The ingredient has been studied in human and animal trials. It was the science I had been looking for all along.
I founded The Postbiotic Company to bring AYA BIOME™ to the UK, Europe, the Middle East and the USA. It took eight months to get it to market. Today you are looking at the finished result: The Postbiotic Company, paving the way for a brand new category in science.
It sits on the shelf in my own clinic, where I see first-hand how clients respond to it. The testimonials from people using it for just a few weeks have justified every one of those eight months. It is not sitting there for long. Stock up while you can.

Sound like you?
Your probiotic did nothing
You took the capsules. You waited. Nothing changed, and nobody could tell you why.
You already take a lot
Greens in the morning, capsules at lunch, something else at night. You want one simple habit.
You already take turmeric
You believe in it. This is turmeric after fermentation, which makes it a different ingredient.
You read the label first
One patented process, one deposited strain, the patent and strain records linked. Check before you buy.
You have just finished antibiotics
You are rethinking what you take for your gut, and you want something that does not rely on live bacteria.
You are over 40
What worked at 30 does not feel the same now. You want something easy that you will keep taking.

Keen to try the rest of the rangeI have been taking the AYA BIOME™ PURE Postbiotic for two and a half months now and have noticed a more youthful glow, as have others! My face looks smoother and brighter. I've been feeling more energetic and am a lot less bloated. I am keen to try other products in the range, especially Women's Wellness!

Five plus stars if I couldI started taking our samples back in December 2025 and within three days I was genuinely feeling the effects: less brain fog, more focus, less anxious and more confident. What surprised me most was the difference it made to my ADHD symptoms. I no longer felt the need to unwind with a glass of wine in the evening. I also used to suffer from really flaky skin. I had forgotten to take PURE for a while and had not been eating well, and the flaky skin came back. I had been trying to get rid of it for two months with no luck. Then I remembered PURE had helped last time, took it that night, and woke up in the morning with my skin completely clear.

More lucid and proactiveI take a lot of supplements, but have done for years, varying what I take with physiological needs and how they help or make me feel. I'd like to think I'm fairly tuned to what my body is saying. This summer I started taking AYA BIOME™ PURE. In the fourth week, without changing any of my other supplements or my work, sleep or exercise regimen, I noticed I felt more lucid and proactive. The only explanation I can think of is the Bhutanese Fermented Turmeric. Thank you.

Very ImpressedI have been trying the Postbiotic Gut Formula for the first time and am very impressed with the results. The bloated feeling I had is under control and getting better all the time. I am very pleased to have made the decision to try the Postbiotic Gut Restore.

Amazed after two weeksI wasn't expecting to notice a difference so quickly, but after just two weeks of taking AYA BIOME™ Gut Restore, I'm genuinely amazed. I've suffered with acne rosacea and ocular rosacea for over 10 years, with itchy facial flare-ups and eyes so dry at night that I usually wake two or three times to use eye drops. In just two weeks, my skin is noticeably clearer and I haven't needed to use the eye drops. No more broken sleep! The improvement has made such a difference to my quality of life. I'm excited to see how much more things improve!

Anything else?
If your question is not here, ask us. A person will answer.
Contact usHow do I take it?
Chew two tablets a day. You do not need water. Ultimate Longevity is different: stir one stick a day into water, food or a smoothie.
What is a postbiotic?
A postbiotic is what bacteria make during fermentation. A probiotic is the live bacteria. A prebiotic is their food. With a postbiotic the fermentation has already happened before it reaches you.
Which one should I choose?
All five contain 500 mg of AYA BIOME™ Fermented Turmeric a day. Most people start with Gut Restore. Take the quiz and we will point you to the right one in under a minute.
How long should I take it for?
We suggest three months. The longest clinical trial ran for 12 weeks, and the guarantee covers your first 90 days, so you have time to decide properly.
How does the guarantee work?
If you are not happy, tell us within 90 days of your first order arriving and we will refund you. One claim per household (one person per address). The full terms are on the guarantee page.
