For a body that struggles to switch off.
Daily nervous-system nutrition, designed around the biology of the vagus nerve.
One daily routine built around Rest · Digest · Recover
Self-reported survey of Yona customers, 2026. Responses are individual experiences and results vary. Food supplements are not a substitute for a varied diet or prescribed medication.
Nine actives. Per 2 capsules:
Other ingredients: a vegan HPMC capsule. No fillers, no binders.
We recommend starting with one capsule a day for the first five days, then moving up to the standard daily dose of two. The gentler start gives your nervous system time to adjust.
Nine actives, independently tested for purity and potency before every batch ships.
Pre-launch. Vagus One ships on 29 September. Order now and your bottle goes out on that date — the estimate below runs from dispatch, not from the day you order.
Dispatched from the UK with Royal Mail or InPost. Estimated delivery is usually within 2–3 days of dispatch. There is an option for expedited shipping at checkout.

If a full cycle hasn't helped your body find its way back down, contact us within 90 days for a refund.
The vagus nerve is one of the body's major communication routes. It carries information between the brain and organs and helps coordinate processes associated with resting, digestion and recovery.
Vagus One provides daily nutrition designed around three parts of that biology:
Finish the day and actually feel done.
“Before I started taking Yona I would get upset very quickly, now I am more relaxed. I also have more motivation to do things where before I couldn’t be bothered.”
Eileen B. · Verified buyer
Finish the meal and move on.
“I have been taking it for nearly a month and I can feel the difference… less bloating, and don’t seem to get any acid indigestion.”
Sally S. · Verified buyer
Sleep. Wake. Feel like it counted.
“The best thing is being able to sleep without the fear of waking up with reflux, and to be able to have a meal and not panic about feeling uncomfortable afterwards.”

Three different experiences.
One nervous system moving through the day.
The vagus nerve doesn't serve a single organ. Its name means wandering — and its influence extends to nearly every system that decides whether your body stays switched on, or stands down.
The vagus begins in the medulla, at the base of the brain. Signals travel both ways along it, but most of the traffic runs upward, from body to brain.
Vagal branches supply the muscles of the pharynx and larynx. Swallowing, and the sound of your own voice, both run on this nerve.
The vagus applies the brake between heartbeats. Its moment-to-moment influence is exactly what heart-rate variability measures.
Vagal fibres help set airway tone and breathing rhythm. It is why a long, slow exhale settles you: you are working the nerve directly.
Vagal signalling drives stomach acid and the muscular waves that move a meal onward. Rest and digest is one instruction, not two.
Around 80% of vagal fibres are sensory rather than motor, and the gut is the single largest source of that traffic. Your digestive tract reports upward almost constantly.
The vagus carries signals to and from the liver, part of how the body keeps track of its own energy state.
Vagal input contributes to digestive enzyme release and to how the body responds when a meal arrives.
The vagus anchors the inflammatory reflex, a built-in brake on inflammation. The link to the spleen runs via the coeliac ganglion rather than as a direct nerve, which is why it is described as a reflex and not a wire.
Vagus One is designed around the nutritional biology of this communication pathway.
All nine actives were selected from published human research. A doctor and a clinical nutritionist advise on Yona’s clinical direction — one on the biology, one on the casework.
Her specialism is autonomic nervous system function and its effect on digestive health — the exact biology Vagus One is built around. Her role here is the reality check: a formula designed around a mechanism can be elegant on paper and mean very little in a consulting room.
A certified Gut Health Practitioner with twenty-five years in clinical nutrition, working in complex digestive dysfunction, nervous system recovery and targeted nutrient repletion. He brings the casework — what actually happens with patients who have not responded to conventional approaches.
In their own words, and at their own stage — from the first week to seven months in.
A selection of eight, posted publicly by customers. Trimmed for length where marked; otherwise in the words they were written in.
You've probably met some of these already — breathing, long exhalations, cold exposure, meditation, electrical stimulation devices. They work through stimulation or behaviour, and they work in the moment.
But the vagus nerve is part of a living nervous system, and normal nervous-system function depends on fundamental nutritional and metabolic processes.
Create an immediate input. These differ in mechanism, intensity and cost, and several of them are free. They are practices and tools—not nutrition.
Support the biology behind signalling. Vagus One is designed around nutrients involved in normal neurological function, neuronal energy and cholinergic biology.
So we asked a different question.What would daily nutrition designed around this biology look like?
Vagus One is organised around three complementary parts of nervous-system biology. Every ingredient has a defined role.
Nutrients selected around normal neurological function and neuronal energy metabolism.
Nutrients involved in cholinergic signalling and acetylcholine metabolism.
Ingredients selected around calm, stress resilience and recovery—without turning the formula into a sedative.
The fat-soluble form of B1, developed in Japan after chemists found thiamine hiding in garlic.
Selected around thiamine-dependent energy metabolism in nerve cells.
Vitamin B1 — the first vitamin ever isolated, and the one whose absence named beriberi: “I cannot, I cannot.”
The standard water-soluble form, alongside the fat-soluble one.
Vitamin B2, from the Latin flavus, “yellow” — first pulled out of milk whey as a pigment, and impossible to take discreetly ever since.
The 5-phosphate form, already activated. Selected around energy metabolism in nerve tissue.
Named after Magnesia, the district of Thessaly whose soil first gave it up. Bound here to glycine, the smallest amino acid there is.
The bisglycinate form, chelated for tolerability. Selected around normal nervous-system function.
CDP-choline, the intermediate every cell membrane is built through — first brought to clinic as a stroke therapy.
Selected around cholinergic biology — the choline side of the calm signal.
Vitamin B5, from the Greek pantothen, “from everywhere” — because it turns up in nearly every living thing.
Precursor to coenzyme A, and the acetyl half of that same signal.
Named from the Latin carnis, “flesh,” after chemists first drew it out of muscle in 1905.
Carries acetyl groups itself — selected around the acetyl side of that signal.
Camellia sinensis — isolated from green tea in 1949, and the reason a cup of tea feels nothing like a cup of coffee.
Selected to support a settled state without sedation.
Crocus sativus — three stigmas per flower, picked by hand, which is why it is the most expensive spice by weight in the world.
At the 30 mg used in human research on mood and stress resilience.
Around 80% of vagal fibres are afferent, carrying information from the organs toward the brain. A smaller proportion carries signals in the opposite direction.
Your brain isn’t simply sending instructions down to your body.
Your organs are continually sending information back up, helping the brain understand what is happening inside you.
That is part of what makes the vagus nerve such an important brain–body communication pathway.
The conversation runs both ways.But most of the traffic travels upward.
Vagal tone is a way of describing vagal and parasympathetic activity.
Researchers often study it indirectly using measures such as heart-rate variability (HRV).
In simple terms, it relates to how effectively the nervous system can move between activation and recovery.
Third-party tested, every batch · High bioavailability
You may already use some of these approaches. They can all be useful—but they work through different mechanisms and on different timescales.
Different tools. Different layers. Different timescales.Vagus One is designed for the nutritional layer.
“I’ve had a lot of gut issues over the last 10 years — gut infections like H. pylori, food poisoning, post-infectious IBS, bloating, indigestion, food sensitivities, reacting when you eat certain foods. I’ve gone through it all.
I even enrolled onto a gut practitioner course so I could understand more about my digestive system. One of the first things they started to talk about was the nervous system, and the link between the gut and the brain. That’s where Yona comes in — it spoke about targeting the vagus nerve. I thought, well, that’s different from a nutritionist telling me to cut this out, cut that out.
I’ve tried a lot of different things over the years, and there’s only a handful that I can say made a tangible, measurable difference. The longer I take it, the better I feel.”
Yvonne M. · in her own words, on camera
We would rather you worked that out now than in week three. Here is who Vagus One is built for — and who should save their money.
Nothing to measure and nothing to time to the minute. One capsule to start, two from day six, with a meal earlier in the day.
We ask for a full cycle before you judge it. Here is what that tends to look like — drawn from what 748 customers told us, and from how the formula is built.
That is the honest answer. You are supplying raw materials, not taking a sedative, so there is no first-night effect to feel. The only job this fortnight is not missing days.
Where people notice something, it usually shows up at night — winding down more easily, or sleep that felt like it did more. Of the customers who noticed a change at all, 64% noticed inside four weeks.
“I am on my 3rd week and I am really feeling the difference.”
Benhilda H. · Verified review
Nutrient status changes over weeks, not days. By now the capsules are part of a meal rather than a task, and what changes tends to arrive as a new baseline rather than an event.
“I didn’t think this would work. I was very suspicious. However after 6 weeks I am much more settled and don’t have the gut issues.”
Jane J. · Verified review
A pattern that took years to set does not shift in three weeks. Ninety days is the point where you have enough to decide.
“So far so good — three weeks in and things are really improving. Interested to see where 12 weeks takes me.”
Sonia J. · Verified review
In the same survey, 81% reported an improvement in their digestive symptoms and 73% felt calmer and less reactive to stress.
Previously called Vagus+ — the formula Vagus One grew out of.
What it is, who it is for, and what to expect.
Vagus One is daily nervous-system nutrition, designed around the biology of the vagus nerve.
Rather than focusing on a single symptom, the formula is built around three layers:
Nerve · Signal · StateIt combines nutrients involved in normal nervous-system function with ingredients selected around cholinergic biology, cellular metabolism and a calmer nervous-system state.
No. Vagus One does not electrically stimulate the vagus nerve.
Vagus nerve devices focus on stimulation. Vagus One focuses on nutrition, providing nutrients and bioactives selected around the biology the nervous system depends on.
Stimulation is one approach. Nutrition is another layer.
Vagus One is designed for people who recognise the feeling: “My body struggles to switch off.”
That might show up as difficulty unwinding, feeling tired but still “on”, stress-responsive digestion, restless evenings, poor recovery or simply feeling more reactive than you used to.
The common pattern is a body that is very good at switching on, but struggles to properly switch back.
Most stress supplements begin with ingredients associated with relaxation.
Vagus One starts with a different question: what does the nervous system itself depend on nutritionally?
That is why the formula is organised around Nerve · Signal · State — combining nervous-system nutrients, ingredients selected around cholinergic biology, and a dedicated State layer with L-theanine and saffron.
Magnesium is an important nervous-system nutrient, which is why Vagus One contains it — 100 mg of magnesium bisglycinate.
But it is only one part of the picture.
Vagus One combines magnesium with carefully selected nutrients and bioactives across the wider Nerve · Signal · State framework, rather than relying on one ingredient alone.
Vagus One is not designed to be a sedative or a stimulant. There is no melatonin, no valerian and no caffeine in the formula.
It is a daily foundational formula rather than something intended to knock you out or give you a noticeable “buzz”.
The formula deliberately includes a State layer with L-theanine and saffron, so it does not feel like a purely stimulating nootropic formula.
Vagus One is designed for consistent daily use rather than an instant effect.
Everyone responds differently, so we recommend looking at how you feel over time rather than judging the product after one or two doses. This is why we position Vagus One as a daily nervous-system foundation rather than a quick fix.
We know some people are particularly sensitive when introducing something new.
If that sounds like you, take it gradually: one capsule a day for the first five days, then move up to the standard two when you are ready. There is no need to rush into the full routine.
If you are unsure at any point, our team is here to help.
Ask your doctor or pharmacist first — particularly if you take prescribed medication, are pregnant or breastfeeding, or have an existing condition. Show them the ingredient list; it names every active and exactly how much of it, which makes that conversation straightforward.
Do not stop or reduce prescribed medication because you have started a supplement. Vagus One is food, not treatment, and it is not a replacement for anything your doctor has given you.
