A Customer in Estonia Used This Peppermint Focus Spray for a Month and Wrote Down What Happened: Clear at First, Then Quieter. I Put Her Month Beside the Twelve-Week Trial Behind Its Main Ingredient.
Brain & Focus Spray is a 30-milliliter sugar-free peppermint spray from Shroomwell, a mushroom company outside Tallinn: lion's mane extract, L-theanine, ashwagandha and three B vitamins, five sprays a day. It ships within Europe only. One four-star review describes a month with it better than any label could, so I used her month as my map.
This is a paid advertisement. Sponsored by Shroomwell.
Martin Keel is the pen name of this desk. The customers quoted on this page are real; their reviews are public on the seller's site, were written in Estonian, and are quoted here in translation. I haven't met them and know nothing about them beyond what they wrote. The small photos beside their reviews are illustrations, not the reviewers. Everything about the bottle, from the label to the shipping table, comes from the seller's own pages, read on September 3 and checked again on September 6, 2026.
Most people who try something for a month don't write it down.
Marta did.
She bought this spray, used it for about a month, and left a four-star review on the seller's site, in Estonian, that reads like a lab notebook.
At first it worked: clarity of thought and energy. She learned to take it in the morning, because later in the day it kept her up. And by the end of the month the effect no longer felt as strong.
That's the most useful thing anyone has written about this bottle, and the seller published it themselves.
I'm going to use it as a map.
Week one. The timing. Week four.
And at each stop, what the trials say about whether her month makes sense.
Here's what the bottle is.
Thirty milliliters of clear liquid in a white plastic bottle with a pump that doesn't let air back in.
You shake it and spray five times into your mouth, once a day.
Sugar-free, sweetened with xylitol and stevia, flavored with peppermint oil, vegan.
Inside: an extract of lion's mane mushroom, an amino acid from tea, an extract of a root from India, and three B vitamins.
Made by a company that grows mushrooms in Estonia, and sold from its own website to addresses in Europe.
Not to the United States. I'll say that again where it matters.
That's the whole product. No capsules, nothing to swallow with water.
Six things inside that the label bothers to count.
I did what I always do.
I read the label before the listing.
I read the trials behind each of the six things, at the doses they actually used.
I read all seventeen reviews, in translation, and kept the three that tell you something.
And I read the shipping table, which decides whether you can buy this at all.
What I found is a bottle that can plausibly give you Marta's first week, and no reason at all to expect it to give you the twelve-week trial.
Bearing one · The bottleThirty Milliliters, Five Sprays, and a Company Outside Tallinn
This is what's on the counter.
A white bottle the height of a lipstick. A pump top. A box with the name in green.
The front says Brain & Focus Spray, then With Lion's Mane, then 30 ml.
The directions, from the seller's page.
Prime the pump a few times before first use. Shake before each use. Five sprays a day. Put the cap back on.
Five sprays is the whole daily dose. Every number on this page is for those five sprays.
The company is Shroomwell, with its office in Peetri, a suburb of Tallinn, and, by its own account, a mushroom lab in the city and a factory and mushroom farm in Tõrva, in the south of the country.
That's what the company says about itself. I couldn't check it and I'm not repeating it as mine.
One thing off the packaging before we go on, because I'd rather you heard it from me.
The box prints the mushroom's Latin name as Hericium erinaceus, which is lion's mane.
The bottle prints Ganoderma lucidum, which is reishi, a different mushroom.
The ingredient list on the seller's page says lion's mane, and the box agrees. I go with the box and the list.
It's a printing error, most likely, and it's still on the bottle you'll receive.
Bearing two · The labelSix Numbers for Five Sprays, and One of Them Is 10,000 Percent
Let me show you the label, because the label is the product.
Per daily dose of five sprays.
Lion's mane extract, 250 milligrams.
L-theanine, 50 milligrams.
Ashwagandha root extract, 25 milligrams.
Vitamin B1, 0.55 milligrams, which the label calls 50 percent of the European reference intake.
Vitamin B3, 8 milligrams, also 50 percent.
Vitamin B12, 250 micrograms, which the label calls 10,000 percent.
Then the base: purified water, xylitol, glycerol, stevia, citric acid, a preservative, peppermint oil and a gum.
Read those numbers the way I did.
Two plant extracts at amounts that sound like doses.
One amino acid at an amount that might be one.
And three vitamins, two at half a day's worth and one at a hundred days' worth.
On an American label the B12 would read about 10,400 percent of the Daily Value. [1]
A number that size isn't a dose. It's a sign that the vitamin is cheap and the label wanted a big figure on it.
The bottle also prints the sentences European law allows for those vitamins: that B1, B3 and B12 contribute to normal psychological function and the normal functioning of the nervous system, and that B3 and B12 contribute to the reduction of tiredness and fatigue.
Those sentences are lawful for any food that carries enough of the vitamin.
They describe what the vitamins do in everyone. They don't describe an improvement in you.
Hold onto the 250 milligrams of mushroom. It's the number the name on the bottle rests on, and it comes back in week four.
Bearing three · Week one"Clarity of Thought and Energy," and What in the Bottle Can Act in an Hour
Marta's first week is the easy part to explain, and the honest part is that the mushroom probably isn't the explanation.
Three things in five sprays can plausibly be felt within the hour.
The peppermint.
A strong mint on a dry tongue at nine in the morning wakes anyone up for a few minutes. That's not pharmacology. It's a mint.
The sweetness.
Xylitol and stevia give the spray a sweet, cool taste with no sugar. Sweet and cold on the tongue is a small jolt, and it's gone in ten minutes.
And the L-theanine, which is the one with a study in your age group.
In a placebo-controlled study of Japanese adults aged 50 to 69 with normal mental-status scores, a single dose of L-theanine went with faster reaction times on an attention task and more correct answers, with fewer omissions, on a working-memory task. [2]
The published summary doesn't give the dose in milligrams or the number of people, so I can't tell you whether 50 milligrams is what they used. I can tell you the effect was measured hours after one dose, not after a month.
Mint, sweetness and one amino acid with a single-dose study. That's a first week. It isn't a month.
The B vitamins don't belong in this list, and I want to say why plainly.
Half a day's B1 and B3, for a man who eats breakfast, changes nothing he can feel.
A hundred days' worth of B12 doesn't either, unless he's actually short of it, and a 2018 Cochrane review of 14 trials in nearly 28,000 people without a deficiency found that B-vitamin supplements probably have little or no effect on thinking, at any point up to five years. [3]
If you suspect you're short of B12, and after 60 it's more common because absorption falls, that's a blood test and a doctor's decision. Not a spray.
Bearing four · The timingWhy She Learned to Take It in the Morning
The second thing Marta wrote is the one I'd underline if I owned the bottle.
Taken later in the day, it kept her up well past her usual hour.
I can't tell you which ingredient did that.
There's no caffeine on the label. The mushroom, the root extract and the amino acid are usually described the opposite way.
What I can tell you is that a mint, a sweet taste and a small ritual at four in the afternoon are all the wrong way round for a man who wants a quiet evening, and that her fix was the right one: morning.
So here's the rule I'd write on the box.
Next to the coffee, at breakfast, and nowhere else.
A bottle that lives on the afternoon shelf will cost you an evening. A bottle that lives next to the coffee tin costs you four seconds.
Bearing five · Week four"The Effect No Longer Felt as Strong," and the Twelve-Week Trial Behind the Mushroom
Now the hard part, and the reason this page exists.
Lion's mane is a white, shaggy mushroom that grows on hardwood trunks in the autumn, and it's the reason the bottle has the word Focus on it.
It has one trial worth reading in people your age.
Thirty-one healthy adults over 50 took a preparation of dried lion's mane fruiting body, 3.2 grams a day, or a placebo, for twelve weeks.
At the end, the mushroom group scored higher on a standard mental-status test than the placebo group.
On a test of visual memory, nothing changed. [4]
Read the three numbers in that trial against the bottle.
Twelve weeks. Marta used it for four.
Three thousand two hundred milligrams a day of the whole dried mushroom. The spray gives 250 milligrams of an extract.
And a standard mental-status test, the kind a doctor gives, not the feeling of a clear morning.
The trial is twelve weeks at almost thirteen times the weight, of a different preparation, measured a different way. Her month and the trial aren't the same experiment, and neither one tells you about the other.
So I'll say the two honest sentences.
Marta's fading isn't evidence that lion's mane doesn't work; a month at this amount was never going to show what twelve weeks at that amount showed.
And Marta's clear first week isn't evidence that it does; a mint and an amino acid can do a first week on their own.
What fades in a month is usually the novelty. What's left after the novelty is the mushroom, and at 250 milligrams a day, the trials haven't looked.
Bearing six · The rootAshwagandha: 25 Milligrams, and the Trial Used 300 for Ninety Days
Third on the label, and the one with the biggest gap between the trial and the spray.
Ashwagandha is a small shrub of dry ground in India, with orange berries in papery husks, and its root has a long place in Ayurvedic practice.
The bottle prints the sentence that it contributes to normal mental and cognitive activity. That's a traditional-use sentence, not a trial result.
The trial that exists is in younger people.
One hundred twenty-five adults aged 20 to 55 who reported feeling under pressure took 300 milligrams a day of a slow-release root extract, or a placebo, for ninety days.
The ashwagandha group scored better on memory and attention tests at the end. [5]
Three hundred milligrams a day for ninety days, in people under 55. Five sprays give 25 milligrams. Twelve times less, in a different age group, for a third of the time.
Reference texts advise care with ashwagandha if you have a thyroid condition or take thyroid hormone.
At 25 milligrams it's a footnote. It's still a footnote worth reading before a daily habit.
Bearing seven · The other reviewsSeventeen Reviews, All in Estonian, and the Three That Tell You Something
The seller's page shows 17 reviews with an average of 4.6.
Twelve gave five stars, three gave four, two gave three.
Its review system marks none of them as a verified purchase, so I can't tell you which ones bought it there; I can tell you they're public on the seller's site, and I read them all in translation.
I kept three.
Not the ones that say "great product" in two words, and not the one that mentions a health problem a doctor had named, which has no place on a page like this.
The three that tell you something you'd want to know before you buy, quoted in translation from the Estonian; the small photos beside them are illustrations, not the reviewers.
I ordered it and have been using it for about a month. At first it had an effect: it gave me clarity of thought and energy. I had to take it in the morning, because taking it later pushed my bedtime much later than usual. Over time the effect no longer felt as strong.
The effect is good, but the taste is a long way from pleasant peppermint.
I like that I can carry it in my bag and use it anywhere. The cap sticks sometimes, but I found that if you clean it with water it works perfectly again.
Read those the way I did.
Marta is the honest month, and I've built the page on her.
Marit gave it three stars and says the taste is a long way from the peppermint on the box. I believe her; a spray with a root extract and a mushroom in it doesn't taste like a candy.
Liisi says the cap sticks and tells you how to fix it. That's the kind of review I trust most, because nobody writes it to sell anything.
Nobody in the reviews I kept claims anything big. One describes a good month that faded. That's the effect I believe in, and it's smaller than the box.
Bearing eight · The likelier explanationWhy a Morning Spray Feels Like Clarity, and What Else Does the Same Job for Free
Suppose you buy it, spray it at breakfast, and feel a little clearer by half past nine.
I'd believe you. And I'd give you three reasons before I gave the mushroom one.
You tasted mint and cold sweetness on a dry tongue. That wakes a man for a few minutes.
You stopped. Shook a bottle, counted five, put the cap back. A small ceremony sharpens the next ten minutes.
You did it in the morning, when you're at your best anyway, and gave the bottle the credit.
None of that is in the mushroom. All of it comes with the bottle.
What actually helps, and costs nothing, is dull.
- Do the hard thinking before eleven. That's when you're sharpest, spray or no spray.
- No coffee after two. The three o'clock cup fixes three o'clock and wrecks eleven.
- One thing at a time. Radio off while you read the manual.
- Ten minutes outside before the hard part of the afternoon.
- A glass of water on the desk, refilled every time you stand up.
Now look at that list and be honest.
You've heard every item since your first physical, and you still don't do them.
Boring loses to coffee every time.
If a peppermint spray gets you to do your hard thinking at nine instead of three, it did its work before the mushroom did anything. And at 250 milligrams, the mushroom is a long way from the trial.
Bearing nine · What it isn'tSix Things Five Sprays Won't Do
- It won't give you the trial's dose of lion's mane. The trial used 3,200 milligrams a day of the whole dried mushroom for twelve weeks; five sprays give 250 milligrams of an extract.
- It won't give you a trial dose of ashwagandha either. Twenty-five milligrams against 300.
- It won't do anything the B vitamins' sentences don't say, and they say "normal." Ten thousand percent of B12 is a label number, not a result.
- It won't taste like the peppermint on the box, according to the one reviewer who said so. Expect mint over something green and bitter.
- It won't ship to the United States. The seller's table covers Europe, from Estonia to the rest of the continent, and stops there.
- It won't come back for a refund once it's open. The seller's rule is the European fourteen days, unopened, at your own return postage.
If that list annoys you, I'd rather you were annoyed now than when the parcel arrives from Tallinn.
Bearing ten · The routineIf You Do Buy It: One Bottle, One Month, Morning Only, One Line a Day
If you're going to spend the money, spend it the way Marta did, and write it down.
- Buy one bottle. Not two, whatever the shipping table tempts you to do. One month is the test.
- Put it next to the coffee tin and use it at breakfast. Five sprays, once, and the cap back on.
- Never after lunch. Marta paid for that lesson so you don't have to.
- Write one line a day. Not "clear" or "foggy." What you were doing at ten, and how it went.
- Keep everything else the same for the month, so you know what the bottle does and not what a new routine does.
- On day thirty, read the first week's lines against the last week's. If the effect faded like hers did, the novelty was the effect. If it held, you've learned something the trials can't tell you, because they never used this amount.
Look at that list the way I do.
Four of the six things are free.
The bottle is the one you'll pay for, and the notebook is the one that will tell you the truth.
Bearing eleven · Who it's forWho It Suits, and Who It Doesn't
This is worth a look if:
- You live at an address in Europe. The seller doesn't ship anywhere else.
- You want a sugar-free, caffeine-free morning ritual with a real label, and you've now seen the label.
- You can hold two ideas at once: real extracts, at amounts far below the trials.
- You like a company with a street address, a phone number and its own mushroom farm, by its own account. You have all three now.
- You'll run it as a thirty-day test with a notebook, the way Marta did, not as a hope.
Give it a miss if:
- You want a trial dose of lion's mane or ashwagandha. Buy the mushroom, or an extract with the trial's milligrams on the label.
- You want something that acts on a condition a doctor has named. This is a food supplement.
- You have a thyroid condition or take thyroid hormone. Ashwagandha is on the label, even at a footnote's worth. Ask first.
- You're sensitive to mushrooms, or to strong mint.
- You want to try it in the afternoon. Read Marta's second sentence again.
- You want it delivered outside Europe. It isn't.
Bearing twelve · Where it's soldFrom Estonia, to Europe Only, With a Fourteen-Day Rule and No Money-Back Guarantee
The bottle is sold by Shroomwell on its own website, and that's the only place this page links to.
The current price is shown there, not here.
The day I read it, one bottle cost a little over twenty euros, before shipping.
Now the two things that matter more than the price.
First, where it ships.
Estonia, cheaply. Latvia and Lithuania for a little more. Finland and Sweden for a little more again. The rest of Europe for a flat charge.
And that's the end of the table. There's no line for the United States, or for anywhere outside Europe.
If you're reading this from an address outside Europe, this bottle isn't for you, and I'd rather say so than have you find out at checkout.
Second, the return rule.
It's the European fourteen days: you can change your mind within fourteen days of delivery, without giving a reason.
The bottle has to go back unopened and unused, at your own postage unless it arrived damaged or wrong, and the refund follows within fourteen days.
Open it, and it's yours. So open one, and leave nothing else to open.

QuestionsWhat Readers Ask Me Before Their First Bottle
Questions readers ask
Is this medicine?
No. It's a food supplement made in Estonia: water, a sweetener, an extract of lion's mane mushroom, L-theanine, an ashwagandha root extract, three B vitamins and peppermint oil. The sentences on the bottle are the ones European law allows for the vitamins and for the root; they describe normal function, not an improvement.
Does it ship to the United States?
No. The seller's shipping table covers Estonia, the Baltic countries, Finland and Sweden and the rest of Europe, and stops there. This page is written for readers with a European address.
What does it taste like?
The box says peppermint. One three-star reviewer says the taste is a long way from pleasant peppermint. Expect mint over something green and bitter, sweetened with xylitol and stevia. No sugar, no caffeine.
How long does a bottle last?
The seller says five sprays a day; it doesn't print the number of sprays per bottle. Marta's review describes about a month, which matches a 30-milliliter pump bottle used once a day.
Will it help my memory or focus?
I can't tell you that, and you should be wary of any page that does. Lion's mane has one twelve-week trial at 3,200 milligrams of whole mushroom a day; the spray gives 250 milligrams of an extract. Ashwagandha's trial used 300 milligrams for ninety days; the spray gives 25. What one customer described is a clear first week that faded by the fourth. That's the honest ceiling.
Why does the box say one mushroom and the bottle another?
I don't know, and nobody at the company told me. The box and the seller's ingredient list say lion's mane, Hericium erinaceus; the bottle prints the name of reishi. I go with the box and the list, and I'm telling you so you're not surprised when you turn the bottle over.
Is 10,000 percent of B12 a lot?
It's a hundred days' worth in one dose, and on an American label it would read about 10,400 percent of the Daily Value. Your body takes what it can use and passes the rest. For someone who isn't short of it, the big Cochrane review found B-vitamin supplements probably make little or no difference to thinking. If you think you are short of it, that's a blood test.
Can I take it alongside what I already take?
Ask your doctor or pharmacist and take the ingredient guide with you. Ashwagandha's reference texts advise care with thyroid conditions, and the seller's page says nothing about pregnancy either way, which means ask. Two minutes at the pharmacy counter answers all of that.
Should I take it in the afternoon when I fade?
Marta tried that and it kept her up. Take it at breakfast, and put the afternoon fade down to coffee timing, which the free list above deals with better than any spray.
What if it arrives and I don't like it?
If it's unopened, you have fourteen days from delivery to send it back at your own postage and get a refund. If it's open, it's yours. That's why the answer to "how many should I buy" is one.
Are the reviews real?
They're public on the seller's site, in Estonian, and I quote three of them in translation, word for word. The seller's review system doesn't mark any of them as verified purchases, so I don't call anyone a verified buyer.
The short versionEverything Above, in Sixty Seconds
- A white 30-milliliter pump spray from Shroomwell, a mushroom company outside Tallinn, Estonia, with a street address, a phone number and an email.
- Five sprays into the mouth, once a day, in the morning. Sugar-free, caffeine-free, peppermint, vegan.
- Per day: 250 milligrams of lion's mane extract, 50 of L-theanine, 25 of ashwagandha root extract, half a day's B1 and B3, and a hundred days' B12.
- Lion's mane's trial: 3,200 milligrams of whole mushroom a day for twelve weeks in adults over 50. [4] Ashwagandha's: 300 milligrams for ninety days in adults under 55. [5] Neither is anywhere near five sprays.
- L-theanine has a single-dose study in adults 50 to 69, which is the honest explanation for a good first week. [2] B vitamins in people who aren't short of them: little or no effect, per Cochrane. [3]
- One real customer's month: clear at first, morning only, quieter by week four. Seventeen reviews, none marked as verified purchases.
- Ships within Europe only. Fourteen-day returns, unopened, at your postage. No money-back guarantee.
- The honest use: a sugar-free morning ritual next to the coffee tin. Buy one, keep a notebook for thirty days, and let the notebook decide.
The last bearingWhat Five Sprays Are Actually Worth
Here's the whole thing in one breath.
A mint, a sweetness and one amino acid that can give you a good first week.
A famous mushroom at a thirteenth of the trial's weight, and a famous root at a twelfth.
A hundred days of a vitamin you almost certainly don't need, and half a day of two you already get.
In a bottle that lives well next to the coffee tin and badly on the afternoon shelf.
If you're a man in Europe who wants a morning ritual with no sugar and no caffeine, and you'll keep a notebook, that's worth one bottle.
Not because of what's in the sprays. Because of what you'll do at nine instead of three.
Buy one, not two, put it next to the coffee, and write one line a day for thirty days. Marta's method is a better judge than I am.

P.S. If you take one thing from this page, take the two numbers. Three thousand two hundred milligrams a day of whole mushroom for twelve weeks in the trial; 250 milligrams of extract a day in the bottle. Everything else about this spray follows from holding those two side by side.
P.P.S. If the afternoon fog has been with you for a year, and it's there in the morning too, talk to your doctor before you buy anything. A morning spray is a small habit. It was never going to answer a question a doctor answers in fifteen minutes.
P.P.P.S. And if you do order it, put it next to the coffee tin, not in the drawer by your reading chair. Marta wrote the only instruction on this page that came from a month of use, and it's that one.
