Ingredient & advertising guide

This page has two jobs. First, it explains every ingredient in the mouth spray we sell, what it is, and what the research does and does not say about it. Second, and this is the part most advertising pages leave out, it lists the headlines we run, tells you which ones are exaggerated, and separates the small number of things that are genuinely supported by evidence from the many that are not.

1. Our headlines, and what is actually true

These are the headlines we have run, grouped by the claim they make. The right-hand column is our own plain assessment. We have marked each family of headlines as Exaggerated, Partly true, Withdrawn, Our headline was wrong or Broadly supported.

The headline as you saw it	What is actually behind it
"Mental Decline Begins When Seniors Can't Spell These 3 Words. Test Now""Top Doctors Say Mental Decline Begins When Seniors Can't Pronounce These 3 Phrases. Can You?""MDs Say Mental Decline Begins When Seniors Can't Pronounce These 3 Phrases. Can You?""Memory Decline Begins When Seniors Say These 3 Phrases (See The List)""Declining Memory Begins When Seniors Say These 7 Phrases. See Which Ones"	Exaggerated There is no set of three words, three phrases or seven phrases whose spelling or pronunciation marks the beginning of anything. Nothing "begins" at a word. Word tasks do appear inside the short memory checks clinicians use, but those checks are given in person and read alongside your history, the things you take and your age. Failing a word online means nothing on its own: plenty of people stumble over a word when they are tired, nervous or being timed. "Top doctors" and "MDs" refer to no specific doctor. See section 4.
"Japan's Oldest Doctors Say Memory Loss Isn't Age: Just Avoid Drinking These 3 Beverages""Japan's Greatest Doctors Say Memory Loss Isn't Age: Just Avoid Drinking These 3 Beverages""Japan's Oldest Doctors Say Memory Loss Isn't Age: Just Avoid Eating These 3 Foods""Japan's Oldest Doctors Say Memory Loss Isn't Age: Just Stop Eating These 3 Foods"	Exaggerated No group of Japanese doctors issued this statement. There is no such panel, no such list, and no source we can point you to. Japan appears in the headline because it is widely associated with long life, which makes the claim feel credible. That is a marketing decision, not a citation. The second half is also wrong. Memory changes with age for everyone, and no diet removes that. What is true is narrower: certain long-term drinking and eating patterns travel with faster slippage on thinking tests in large population studies. [1] [2] Association is not proof of cause, and "just avoid these three" is not how any of it works.
"Nobel Prize's Doctors Say Memory Loss Isn't Age: Just Stop Eating These 3 Foods"	Withdrawn We retract this one outright. No Nobel laureate has endorsed this page, this product, or any list of three foods on our behalf. Attaching the Nobel Prize to an advertisement implies an authority that does not exist and we should not have run it.
"The Overlooked Boxed Cereal Now Tied to 8 Out of 10 Memory Cases"	Our headline was wrong There is no such statistic. No study ties any cereal to eight out of ten cases of anything, "memory cases" is not a category any researcher uses, and no cereal has been "overlooked" by anyone: the sugar figure is printed on the side of every box. The number was invented for the headline and we withdraw it. The grain of truth is the same as for the other cereal headlines below: a diet heavy in ultra-processed food, the sweet cereal shelf included, travels in a large Brazilian study with somewhat faster slippage on thinking tests over eight years. [2] That is a modest association across thousands of people, not eight in ten of anyone. See section 3.
"Brain Experts Now Say These 3 Cereals Age the Brain Faster Than Time""Scientists Now Say This 1 Cereal Ages the Brain Faster Than Time"	Exaggerated No food ages the brain "faster than time." That phrase was written for effect and it is not a finding from any study. It is also internally inconsistent: in one version it is three cereals, in another it is one, because the number is something we test for click-through, not something we measured. The grain of truth: diets high in ultra-processed food are associated with somewhat faster slippage on thinking tests over years. [2] That is a modest effect across a population, not a fate sealed by a bowl of cereal. See section 3.
"Doctors Now Say This Popular Evening Drink Is Behind Memory Loss""Doctors Now Say This Popular Evening Drink Is Behind Brain Health Decline"	Partly true The "evening drink" is alcohol, and of everything our ads point at, this is where the evidence is strongest. In British civil servants followed for thirty years, higher drinking went with shrinkage of the hippocampus, the region most involved in forming memories, and with faster slippage in word fluency; light drinkers had no edge over non-drinkers. [1] What is overstated is the word "behind." Alcohol is one contributing factor among many, not the cause of memory slips. Cutting back is a genuinely good idea. The spray we sell contains no alcohol.
"Doctors Name 5 Popular Drinks Now Tied To Memory Decline. Coffee Tops The List""Seniors: These 4 Drinks May Be Aging Your Brain Faster""The 4 Drinks Brain Doctors Want Seniors to Quit""Doctors: 3 Popular Drinks Now Tied to Memory Loss in Seniors"	Exaggerated Notice that the count changes: two drinks, three, four, five. It changes because it is an advertising variable we rotate, not a number that came out of a study. No neurologist is named in any version, because none was consulted. "Coffee tops the list" is the clearest thing we have got wrong: none of the studies on this page is about plain coffee. If you drink coffee and enjoy it, this headline gave you a reason to worry that the evidence does not support. Our own article about this spray says keep your coffee, before two in the afternoon. See section 2.
"Brain Doctors: Quit These 4 Drinks Before It's Too Late"	Exaggerated No brain doctor was consulted for this headline, and there is no "too late." The deadline was invented to make you click. The four drinks are the ones in section 2: alcohol, sugar-sweetened soft drinks, energy drinks and sweetened coffee-shop drinks. Cutting back on them is sensible for your sleep, your weight and your wallet, and heavy drinking travels with poorer memory outcomes over years. [1] There is no evidence that quitting them on any particular day changes anything about your memory, and there is no age after which the change stops being worth making. See section 2.
"Memory Slipping? Check These 4 Everyday Drinks First"	Partly true Half right, in the wrong order. If your memory is slipping, the first thing to check is not a drink; it is a conversation with your own clinician about sleep, hearing and the things you take every day, none of which is fixed by changing what you pour. The four drinks are the everyday ones in section 2: alcohol, sugary soft drinks, energy drinks and sweetened coffee drinks. Reviewing them is a reasonable second step, mostly for sleep. Not enough plain water belongs on the list too, and it is one our own article keeps on the desk. See sections 2 and 5.
"America's Top Experts Say Mental Decline Isn't Aging: Just Avoid These 5 Kitchen Drinks"	Exaggerated The same construction as the "Japan's doctors" headline above, with the country changed. No panel of American experts issued this statement, and we cannot point you to one. Memory changes with age, and no drink removes that. The five kitchen drinks are alcohol, sugar-sweetened sodas, energy drinks, sweetened coffee-shop drinks and sweetened bottled teas, all in section 2, where the honest version of each is written out. "Just avoid" overstates what any of that evidence shows. See section 2.
"Still Sharp at 90? Seniors Are Rethinking These 3 Everyday Foods"	Partly true The gentlest of our headlines, and still an overstatement. Nobody knows what keeps a particular person sharp at 90, and no single food does it. The three everyday foods are sugary breakfast cereals, processed meats and packaged baked goods, all in section 3. Eating less of them is part of the long, slow habits in section 5, and no food is a promise at any age. See sections 3 and 5.
"Drink one cup a day and watch your memory change"	Exaggerated There is no cup. The product is five sprays into the mouth with breakfast. Nothing in those sprays has been shown to change memory: 250 milligrams of lion's mane extract against the 3.2 grams of mushroom used in the trial everyone quotes, [3] 25 milligrams of ashwagandha against the 300 in the trial usually cited, [4] and 50 milligrams of L-theanine, a quarter of the 200 milligrams a day in its four-week trial. [5] What a daily dose can honestly give you is a small fixed gesture at breakfast that the rest of a routine hangs on. "Watch your memory change" should not have been written. See section 7 and the ingredients below.
"A customer used this peppermint focus spray for a month: clear at first, then quieter"	Broadly supported This is a real, public review on the seller's site, written in Estonian and quoted in translation, and our article is built around it. The reviewer describes clarity and energy in the first weeks, learning to use the spray in the morning because later use kept her up, and a weaker effect by the end of the month. We repeat it because it is the most useful thing anyone has written about the product, and we put it beside the twelve-week trial of lion's mane (3.2 grams a day of whole mushroom, [3]) to show that her month and the trial are not the same experiment. One customer's month is not evidence that the spray works, and her fading is not evidence that it does not; it is one honest account, and we treat it as exactly that.

2. Every drink our ads point at

Our headlines have referred, in different versions, to "3 beverages", "4 drinks", "5 popular drinks", "2 popular drinks" and "this popular evening drink" without ever naming them. Here is the complete list of what we were pointing at, and what the research actually supports for each one. Where a study is cited, it is observational unless stated otherwise: it can show that two things travel together in a population, not that one causes the other.

3. Every food our ads point at

The food headlines referred to "3 foods" and to "cereals": one cereal in some versions, three in others. Again, the number was ours, not a finding. Here is what was meant, and what stands behind it.

4. The "3 words" and "7 phrases" tests

Several of our headlines invite you to test yourself on words or phrases: spell these three words, pronounce these three phrases, see whether you say these seven phrases. There is no such validated test, and we cannot give you a real one, because a real one does not work that way.

What an actual memory check looks like. Clinicians use short structured checks. They do include word tasks: recalling three unrelated words after a delay, naming animals, repeating a sentence. But three things make them different from an online quiz:

• They are given in person, in a standard way, by someone trained to do it.
• The score is read against your age and education, not against a fixed pass mark.
• A low score is a reason for a longer conversation with your clinician, never a verdict by itself.

These checks also produce false alarms. Poor sleep, trouble hearing, pain and simply being nervous all lower scores in people whose memory is fine. This is precisely why an online word quiz is meaningless: it has none of the context that makes the real check useful.

5. Everyday habits worth more than any bottle

If we only had one section to be useful in, this would be it. Occasionally forgetting a name and recalling it later, misplacing your glasses and finding them, or rereading a paragraph after lunch is ordinary at every age. None of the habits below is a supplement, a spray, or a list of three foods, and none of them can be sold to you by us.

• Sleep enough, at regular hours. Keep coffee to the morning, and keep this spray there too.
• Get your hearing and your eyesight checked, and use hearing aids or glasses if you need them: straining to hear or see looks a great deal like not remembering.
• Walk, most days. Regular walking counts.
• Drink less alcohol. ^[1]
• Eat more like the MIND pattern and less from the ultra-processed shelf. ^{[7] [2]}
• Stay in touch with people. Conversation is exercise for memory.
• Keep learning something: a language, an instrument, a route you have never driven.
• Once a year, take everything you take to the pharmacist.
• Ask your clinician for a B12 level if nobody has checked it in a few years; the stomach takes up less of it with age.

These are unglamorous. They cannot be delivered in a headline, they take years, and they are, by a wide margin, the most useful things on this entire page.

6. Ingredient guide: what is actually in the spray we sell

What each ingredient in Shroomwell Brain & Focus Spray is, what it is traditionally used for, and what the cited research says. This is a food supplement sold in the European Union, not a medicine. Five sprays a day, the label's daily dose, carry 250 milligrams of lion's mane extract, 50 milligrams of L-theanine, 25 milligrams of ashwagandha root extract, 0.55 milligrams of vitamin B1, 8 milligrams of vitamin B3 and 250 micrograms of vitamin B12, printed as 50, 50 and 10,000 percent of the EU reference intake. The other ingredients are water, xylitol, glycerol, stevia, citric acid, potassium sorbate, peppermint oil and xanthan gum. The carton and the bottle print two different Latin names for the mushroom; everything else on the packaging says lion's mane, and we go by that. Where a study is cited below, it used one ingredient at a time, at a dose several times larger than the spray delivers; none of it tested a spray, and none of it tested this product. Read the statement at the end of this section before you buy anything.

Lion's mane (Hericium erinaceus), fruiting body

An edible mushroom with long, white, downward-hanging spines that grows on older beech and oak trees in temperate forests across the Northern Hemisphere. It is eaten as food, especially in East Asia and the United States, with a texture often compared to crab or lobster.

Traditional and everyday use. Known as yamabushitake in Japan and houtougu in China, it has a long history of use as a food and in East Asian and Native American traditions.

What the research says. In a 12-week placebo-controlled trial of 31 healthy adults over 50, a daily lion's mane fruiting-body preparation (3.2 g/day) was associated with higher scores on a standard mental-status test compared with placebo.^[3] A visual-retention test in the same trial did not change, and the dose was far larger than most blends and extracts deliver. In a separate pilot trial in 41 healthy adults aged 18 to 45, a single 1.8 g dose was associated with faster performance on the Stroop task an hour later, while 28 days of it produced only a non-significant trend on self-rated stress.^[8]

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 250 mg (per daily dose of 5 sprays)

Good to know. Generally regarded as safe as a food. Stomach discomfort, nausea and skin rash were reported by a few participants in one clinical study. Avoid if you are allergic to mushrooms.

L-theanine

An amino acid found almost exclusively in tea leaves (Camellia sinensis) and in a few mushrooms. A cup of brewed green tea contains roughly 25 to 60 mg of it. It is what gives green tea its savoury, brothy taste.

Traditional and everyday use. Consumed for centuries as part of everyday tea drinking in China and Japan; isolated and named in Japan in 1949.

What the research says. In a placebo-controlled study in men and women aged 50 to 69, a single dose of l-theanine was associated with a faster reaction time on an attention task and with more correct answers and fewer omission errors on a working-memory task.^[9] The published summary of that study does not state the dose used, so no comparison with any product amount can be made from it. In a four-week crossover trial of 30 healthy adults averaging 48 years, 200 mg a day was followed by better verbal-fluency and executive-function scores; against placebo the verbal-fluency gain showed in the half who started lower, and two authors worked for the supplier.^[5]

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 50 mg (the amino acid in green tea)

Good to know. Generally well tolerated. If you are pregnant, nursing, or take anything daily, talk to your doctor before adding any supplement.

Ashwagandha (Withania somnifera), root extract

A short shrub of the nightshade family that grows in India, the Middle East and parts of Africa. The root is dried and extracted; the plant is also called Indian ginseng or winter cherry.

Traditional and everyday use. Used in Ayurveda, the traditional medicine of India, for more than 3,000 years, usually as a root powder taken with milk or ghee.

What the research says. In a placebo-controlled trial of 125 healthy adults aged 20 to 55 who reported stress, 300 mg per day of a sustained-release root extract for 90 days was associated with better memory and focus scores, better sleep and lower stress ratings than placebo.^[4]

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 25 mg (root extract)

Good to know. Rare reports of harm to the organ that processes what you swallow have been described with ashwagandha products: stop and talk to your doctor if you notice unusual tiredness, dark urine, or yellowing of the skin or eyes. Not for use in pregnancy. Talk to your doctor before use if you take anything daily for your hormones, or if you take anything daily.

Vitamin B1 (thiamine)

A water-soluble vitamin the body cannot store in quantity, so it has to come from food every few days. It is found in whole grains, pork, fish, beans and fortified breads and cereals.

What the research says. A Cochrane review of 14 trials in 27,882 cognitively healthy adults concluded that B-vitamin supplements probably have little or no effect on global cognitive function up to five years.^[10] In the European Union, thiamine carries an authorised claim that it contributes to the normal functioning of the nervous system.

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 0.55 mg (50 % of the EU reference intake)

Good to know. Very well tolerated from food and supplements; no upper limit has been set.

Vitamin B3 (niacinamide)

One of the two common forms of vitamin B3, also called nicotinamide. Unlike the other form, nicotinic acid, it does not cause the skin flush that high doses of niacin can produce. It occurs in meat, fish, nuts, legumes and enriched grains.

What the research says. A Cochrane review of 14 trials in 27,882 cognitively healthy adults concluded that B-vitamin supplements probably have little or no effect on global cognitive function up to five years.^[10] In the European Union, niacin carries authorised claims that it contributes to normal psychological function and to the reduction of tiredness and fatigue.

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 8.0 mg (50 % of the EU reference intake)

Good to know. Well tolerated at the amounts found in supplements of this size. Talk to your doctor before taking it if you take anything daily.

Vitamin B12 (methylcobalamin)

A vitamin found naturally only in animal foods — meat, fish, eggs and dairy — and in fortified products. The body absorbs it through a two-step process in the stomach and small intestine that becomes less efficient with age, which is why supplement doses are often many times the daily requirement: only a small percentage of a large oral dose is taken up.

What the research says. A Cochrane review of 14 trials in 27,882 cognitively healthy adults concluded that B-vitamin supplements, including vitamin B12, probably have little or no effect on global cognitive function up to five years.^[10] That review says nothing about people who are actually short of B12; in the European Union the vitamin carries authorised claims that it contributes to normal psychological function, to normal functioning of the nervous system and to the reduction of tiredness and fatigue.

Amount per serving in Brain & Focus Spray with Lion's Mane 30 ml. 250 µg (10,000 % of the EU reference intake)

Good to know. No upper limit has been set, because unabsorbed vitamin B12 is not stored. A blood test is the only way to know whether you are short of it; ask your doctor rather than guessing.

Peppermint essential oil (Mentha arvensis)

The oil pressed from the leaves of a mint plant, dominated by menthol, which is what produces the cold sensation on the tongue. It is used in tiny amounts as a flavour in food, confectionery and oral products.

Traditional and everyday use. Mint leaves have been used as a culinary flavouring and in teas around the Mediterranean and in Asia for thousands of years.

Good to know. Some people find the taste strong. Rarely, mint can cause heartburn or an allergic reaction.

7. What we can and cannot promise

Set against the headlines that brought you here, this is the complete and honest position.

Things we cannot promise, and that nobody selling you a supplement can:

• That this spray will improve your memory or focus.
• That it will stop memory from changing with age.
• That it offsets alcohol, sugar, processed food, or any drink or food named on this page.
• That it can replace anything a clinician gave you, or make a yearly look at what you take unnecessary.
• That any doctor in Japan, any Nobel laureate, any neurologist or any "brain expert" recommends it. None has.
• That a word or phrase quiz can tell you anything about your brain.
• That a spray is absorbed better than a capsule. The seller says so; no published comparison of this product exists.
• That five sprays deliver the 3.2 grams of lion's mane, the 200 milligrams of L-theanine or the 300 milligrams of ashwagandha used in the trials. The label says 250, 50 and 25 milligrams.
• That the words "Brain & Focus" on the bottle describe anything that has been shown. They are a product name, and the label's own health claims are the European Union's permitted wording about normal function, not findings about this spray.

Things we can say honestly:

• It is a 30-millilitre pump spray sold as a food supplement, made in Estonia by a company that publishes four addresses, a phone number and an email; every ingredient is listed above with the amount printed on the label.
• It contains no sugar, no alcohol and no caffeine.
• The three B vitamins in it are real nutrients. Trials of B vitamins in people who are not short of them have found little or no effect on thinking; ^[10] a blood test, not a bottle, tells you whether you are short.
• The price, the shipping terms (within Europe only; no shipping to the United States) and the return terms (an unopened, unused product may be returned within 14 days of receipt at the buyer's postage; there is no refund on an opened bottle) are exactly what is written on the seller's pages. Nothing more, and no promise made elsewhere overrides them.
• The customer reviews we quote are real and public on the seller's site, written in Estonian and translated by us; the seller's review system marks none of them as a verified purchase, so we do not either. Individual experiences are not evidence.
• We earn a commission if you buy. That is our interest in this, stated plainly.
• Nothing here is medical advice, and none of it replaces your own clinician.

8. Questions people ask us

Did a Japanese doctor, a Nobel laureate or a neurologist really say this?

No. Those attributions are advertising language. No named or identifiable expert made those statements, and none has endorsed this product.

So is coffee bad for my memory or not?

None of the studies on this page is about plain coffee, and our "Coffee Tops The List" headline overstated it. What is worth watching is added sugar in coffee drinks, and caffeine late enough in the day to spoil your sleep.

Is this product a medicine?

No. It is a food supplement sold in the European Union, and it is not a substitute for anything a clinician gave you.

Why do the carton and the bottle print two different Latin names?

The carton says Hericium erinaceus, which is lion's mane. The bottle says Ganoderma lucidum, which is reishi, a different mushroom. Everything else on the packaging, the seller's page and the label's own amounts say lion's mane, so we treat the bottle's Latin name as a printing error, and we tell you about it because you would want to know.

Is there anything to be careful about?

Ashwagandha is on the label. Rare reports of harm to the organ that processes what you swallow have been described with ashwagandha products; if you notice unusual tiredness, dark urine, or yellowing of the skin or eyes, stop and speak to your clinician. It is not for use in pregnancy, and if you take anything daily, show the bottle to your pharmacist first. If mushrooms or strong mint do not agree with you, this spray will not either.

Does it ship to the United States?

No. The seller ships within Europe only, from Estonia, with shipping fees by zone. If you are in the United States, this product is not available to you from the seller, and this page does not pretend otherwise.

If your own headlines are exaggerated, why should I believe this page?

A fair question. Do not take our word for it. The references below are real, published sources you can look up yourself, and nothing in sections 4 and 5 requires you to buy anything or trust us. If this page and our headlines disagree, believe this page.

Does this page cost anything?

No. There is nothing to sign up for, and you are welcome to read it, close the tab and never come back.

Can I check these claims myself?

Yes, and you should. Every numbered reference below can be found by searching its authors and journal.

These are the sources behind the claims marked with a number above. Several are observational studies, which can show association but not cause. We have deliberately not cited anything for the claims we describe as exaggerated, because there is nothing to cite.
