Ingredient & advertising guide

This page has two jobs. First, it explains every ingredient in the product 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 We have marked each family of headlines as Exaggerated, Partly true, Withdrawn or Broadly supported.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 mental decline. Nothing "begins" at a word. Word-finding and naming tasks do appear inside real cognitive screening tools, but those tools are administered and interpreted by a clinician alongside your history, your medications and a physical exam. Failing a word online means nothing on its own: plenty of people with perfectly healthy brains stumble over a word when they are tired, anxious, or being timed. "Top doctors" and "MDs" refer to no specific doctor. See section 5.
"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 in an important way. Memory loss is strongly related to age. Age is the single largest risk factor for dementia, and no diet removes it. What is true is narrower: certain long-term drinking and eating patterns are associated with faster cognitive decline in large population studies. 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.
"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 added sugar and refined starch are associated with poorer memory scores and greater cardiovascular risk over years. 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. Heavy and even moderate regular drinking has been linked in long-running studies to worse brain outcomes, including shrinkage of the hippocampus, the region most involved in forming memories. Excessive alcohol is one of the risk factors named in the 2024 Lancet Commission on dementia. [1] [2] What is overstated is the word "behind." Alcohol is one contributing risk factor among many, not the cause of memory loss. Cutting back is a genuinely good idea. It is not a cure, and it will not undo damage already done.
"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""Neurologists Say Cognitive Decline Isn't Age: Just Stop Drinking These 2 Popular Drinks""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. Large reviews of coffee and cognition have generally not found ordinary coffee drinking to be a risk factor for dementia; several report a neutral or modestly favourable association. If you drink coffee and enjoy it, this headline gave you a reason to worry that the evidence does not support. 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 heart, your sleep and your weight, and long-running population studies link heavy use of the first two to poorer cognitive outcomes over years. 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 your doctor, because several treatable causes listed in section 6 look exactly like memory loss and none of them 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 and for your heart. Not enough plain water belongs on the list too, and it is one our own article keeps on the table, refilled between columns. See sections 2 and 6.
"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. Mental decline is strongly tied to age, and no drink removes that. The five kitchen drinks are alcohol, sugar-sweetened sodas, diet sodas, energy drinks and sweetened coffee-shop drinks, 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. The largest studies point to blood pressure, hearing, physical activity, social contact and education far more than to any food; see section 7. The three everyday foods are sugary breakfast cereals, processed meats and packaged baked goods, all in section 3. Eating less of them is associated in population studies with better long-term brain and heart outcomes. That is a modest, slow effect across a population, and no food is a guarantee at any age. See sections 3 and 7.
"Drink one cup a day and watch your memory change"	Exaggerated There is no cup. The product is two tablespoons of a liquid, poured from the fridge door and taken straight or in a drink. Nothing in that serving has been shown to change memory: four of its ingredients are vitamins and choline at ordinary amounts, and the eleven in its two blends carry no stated amount at all, so no comparison with any trial is possible. B vitamins do little for thinking in people who are not short of them. [3] What a daily serving can honestly give you is a fixed point in the morning that the rest of a routine hangs on. "Watch your memory change" should not have been written. See sections 7 and 9, and the ingredients below.
"Neurologists Name 5 Popular Prescriptions Now Tied to Memory Decline"	Partly true, and the most dangerous to act on This one is closest to real research. Several widely prescribed drug classes have been linked in large studies to higher dementia risk, and prescribing guidelines already flag some of them as poor choices for older adults. [4] [5] [6] But an advertisement is the worst possible reason to change a prescription. Stopping some of these medicines suddenly can cause seizures, dangerous rebound anxiety, or a return of the condition being treated. Never stop or change a prescribed medicine because of something you read in an ad, including ours. Read section 4 before you do anything.

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 "5 prescriptions" headline

Our headline said "5 popular prescriptions now tied to memory decline." It named none of them. These are the drug classes that research has actually flagged. "Tied to" means associated in observational studies, not proven to cause.

What this section is not. It is not a claim that these medicines cause dementia, not medical advice, and not a suggestion that a liquid supplement is an alternative to any of them. It is a prompt to have one specific conversation with a professional who knows your history.

5. 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 actual cognitive screening looks like. Clinicians use short structured tools. The Mini-Cog, the MoCA (Montreal Cognitive Assessment) and the MMSE are the common ones. 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 administered in person, in a standard way, by someone trained to do it.
• The score is interpreted against your age and education, not against a fixed pass mark.
• A low score is a reason for further evaluation (bloodwork, medication review, history from a family member, sometimes imaging), never a diagnosis by itself.

Screening tools also produce false alarms. Anxiety, poor sleep, hearing loss, depression, pain and simply being nervous all lower scores in people whose brains are fine. This is precisely why an online word quiz is meaningless: it has none of the context that makes the real instrument useful.

6. Real warning signs, and the causes worth ruling out

The genuinely useful list is not about spelling. It is about whether memory or thinking has changed enough to interfere with everyday life. Signs that deserve a medical appointment include:

• Memory loss that disrupts daily life: repeatedly asking for the same information, relying on notes and family for things you used to handle yourself.
• Difficulty completing familiar tasks: a routine recipe, a regular route, paying the usual bills.
• New trouble following or joining a conversation, stopping mid-sentence, or calling things by the wrong name.
• Confusion about time or place: losing track of dates or seasons, or how you got somewhere.
• Trouble judging distance, or reading. Worth checking, since it can also be vision.
• Putting things in unusual places and being unable to retrace steps, sometimes with a sense that others are to blame.
• Noticeably poorer judgement, especially about money.
• Withdrawing from work, hobbies or social life; changes in mood, personality, suspicion or apathy.

Ordinary ageing looks different: occasionally forgetting a name and recalling it later, misplacing your glasses and finding them, needing help with an unfamiliar device, taking a moment to find a word, re-reading a column of figures on a short night. That is normal and common at every age.

7. What actually has the best evidence

If we only had one section to be useful in, this would be it. The 2024 report of the Lancet standing Commission on dementia concluded that nearly half of dementia cases worldwide, around 45%, could potentially be prevented or delayed by addressing fourteen modifiable risk factors across the life course. ^[1] Not one of them is a supplement, a liquid, or a list of three foods.

• Treat hearing loss. Use hearing aids if you need them.
• Control blood pressure from mid-life onward. Take the medication as prescribed.
• Treat high LDL cholesterol and manage diabetes.
• Do not smoke.
• Stay physically active. Regular walking counts, and it is free.
• Limit alcohol.
• Treat depression, and take it seriously in older adults.
• Stay socially connected. Isolation is a measured risk factor, not a soft one.
• Correct vision loss: get cataracts treated, keep the prescription current.
• Protect your head from injury; reduce fall risk at home.
• Sleep properly. Persistently short sleep in mid-life has been associated with higher dementia incidence. ^[9]
• Keep learning: education and continued mental engagement across life.
• Maintain a healthy weight and reduce exposure to air pollution where you can.

These are unglamorous. They cannot be delivered in a headline, they take years, and none of them can be sold to you by us. They are also, by a wide margin, the best-supported things on this entire page.

8. Ingredient guide: what is actually in the product we sell

What each ingredient in Neurologic is, what it is traditionally used for, and what the cited research says. This is a liquid dietary supplement, not a medicine. Four of its ingredients carry a stated amount on the label; the other eleven sit inside two "proprietary blends" of 815 mg and 655 mg with no amount given per ingredient, so for those eleven no comparison with any study is possible. One label line, folate, prints two figures that do not agree with each other; the seller's phone number is the place to ask which is right. Read the statement at the end of this section before you buy anything.

Vitamin E (as d-alpha tocopherol acetate)

A fat-soluble vitamin that works as an antioxidant in cell membranes. The label form, d-alpha tocopherol acetate, is the natural form of the vitamin with an acetate group attached to make it stable in a liquid. Nuts, seeds, vegetable oils, spinach and avocado are the usual food sources.

What the research says. In the Women's Health Study, 6,377 generally healthy women aged 65 or older took 600 IU of vitamin E on alternate days for up to 9.6 years and gained no cognitive benefit over placebo.^[12] That amount is many times the 7.5 mg in this product, so the trial says nothing in favour of the label amount either.

Amount per serving in Neurologic. 7.5 mg (50 % DV)

Good to know. At high supplemental doses vitamin E can interfere with vitamin K and raise the risk of bleeding, which matters if you take anything that thins the blood; the amount here is modest. The upper limit for adults is 1,000 mg a day. Talk to your doctor before use if you are under a doctor's care.

Folate (as 5-formyltetrahydrofolate from calcium folinate)

A water-soluble B vitamin, also called vitamin B9, found in leafy greens, beans, lentils, asparagus and fortified grains. The label form is calcium folinate, also known as folinic acid or leucovorin, a reduced folate that the body can use without the enzyme step that ordinary folic acid needs.

What the research says. A Cochrane review of 14 trials in 27,882 cognitively healthy adults concluded that B-vitamin supplements, including folic acid, probably have little or no effect on global cognitive function up to five years.^[3] That review says nothing about people who are actually short of folate.

Amount per serving in Neurologic. 7.5 mg, as printed (printed beside it as 50 % DV; the two figures do not agree with each other, and 50 % of the 400 mcg Daily Value would be 200 mcg)

Good to know. The upper limit for folic acid from supplements and fortified food is 1,000 mcg a day; large amounts of supplemental folate can hide a shortage of vitamin B12 on a blood test. Talk to your doctor before use if you are under a doctor's care.

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.^[3] 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 Neurologic. 400 mcg (16,667 % DV)

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.

Choline (from Vitacholine® choline bitartrate)

An essential nutrient that is not strictly a vitamin. The body uses it to make acetylcholine, a messenger chemical involved in muscle control, memory and many other nerve functions, and phosphatidylcholine, a building block of every cell membrane. Eggs, meat, poultry, fish, cruciferous vegetables, peanuts and dairy are the main food sources. Vitacholine is a branded choline bitartrate, the common supplement salt.

What the research says. In a dementia-free community cohort of 1,391 adults aged 36 to 83, higher choline intake from food was associated with better scores on verbal and visual memory tests.^[13] That is an association with diet, not a trial of a supplement, and it does not show that adding choline improves memory.

Amount per serving in Neurologic. 100 mg (18 % DV)

Good to know. The upper limit for adults is 3,500 mg a day; very large intakes have been associated with low blood pressure, sweating, a fishy body odour and stomach upset. The amount here is far below that. Talk to your doctor before use if you are under a doctor's care.

Aloe vera juice (Aloe barbadensis, inner leaf gel)

A cactus-like plant that grows in hot, dry climates. Products are made from different parts of the leaf: the clear gel from the inner leaf, the bitter yellow latex from the outer layer, and the whole crushed leaf. In this product it is the inner-leaf gel, pressed into a juice, and it most likely serves as part of the liquid base of the blend.

Traditional and everyday use. The gel has been applied to the skin for centuries; aloe drinks are a common beverage ingredient.

What the research says. No research links aloe to memory or attention, and we make no claim for it here.

Good to know. Aloe latex is a laxative and in 2002 the FDA required its removal from over-the-counter laxative products for lack of safety data; the inner-leaf gel is the milder part. Oral aloe leaf extracts have been linked to rare cases of liver inflammation. Talk to your doctor before use if you have a liver condition or are under a doctor's care.

Acetyl-L-carnitine

The acetylated form of carnitine, a compound the body makes from amino acids and also gets from meat and dairy. Carnitine carries long-chain fatty acids into the mitochondria, the parts of the cell that burn fuel. The acetyl form is the one usually sold and studied for the nervous system; it is available without prescription as a supplement.

What the research says. The research on acetyl-L-carnitine and thinking has been done in people with a diagnosed condition, not in healthy adults, so none of it can be cited here and we make no claim for it.

Good to know. Generally well tolerated; large amounts can cause nausea, cramps or diarrhoea and a fishy body odour. Talk to your doctor before use if you have a thyroid or seizure-related condition or are under a doctor's care.

Alpha GPC (L-alpha-glycerylphosphorylcholine)

A compound made of choline joined to a glycerophosphate group. The body makes small amounts of it when it breaks down phosphatidylcholine, and it occurs naturally in milk and organ meats. In a supplement it is a concentrated source of choline that is also sold, in some countries, as a medicine for uses that have nothing to do with a healthy adult's memory.

What the research says. Trials in healthy adults are small and short, and none in healthy older adults could be found, so we make no claim for it here.

Good to know. Can cause headache, heartburn or dizziness in some people. Talk to your doctor before use if you are under a doctor's care.

Phosphatidylserine (from non-GMO soy)

A phospholipid, one of the fatty building blocks of cell membranes, present in high concentration in brain tissue. Supplement phosphatidylserine is made from soy or sunflower lecithin; this product uses soy.

What the research says. In a six-month double-blind trial of 78 Japanese adults aged 50 to 69 with memory complaints, soy phosphatidylserine at 100 or 300 mg a day was safe, and test scores rose similarly in every group including placebo; only the subgroup that started with low scores improved from its own baseline, mostly in delayed word recall.^[14] The main comparison with placebo, in other words, was null.

Good to know. Made from soy, so relevant to anyone with a soy allergy: note that the store's own product tags say "Soy Free" while the panel says "from Non-GMO soy". Talk to your doctor before use if you take anything that affects clotting or are under a doctor's care.

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.^[15] The published summary of that study does not state the dose used, so no comparison with any product amount can be made from it.

Good to know. Generally well tolerated. If you are pregnant, nursing, or under a doctor's care, talk to your doctor before adding any supplement.

Alpha lipoic acid

A sulphur-containing compound, also called thioctic acid, that the body makes in small amounts and uses as a helper for several enzyme complexes in the mitochondria. It occurs in food bound to protein, in spinach, broccoli and organ meats; supplements contain the free form. It is a direct antioxidant, although any effect on free radicals in the body is likely brief.

What the research says. No trial of alpha lipoic acid on memory or attention in healthy adults could be found, and we make no claim for it here.

Good to know. At supplement doses it can enhance the uptake of glucose by cells, which matters to anyone who manages their blood sugar. Talk to your doctor before use if you are under a doctor's care.

L-tyrosine

An amino acid found in protein foods such as cheese, meat, fish, eggs, beans and nuts; the body also makes it from another amino acid, phenylalanine. It is the starting material for the messenger chemicals dopamine and norepinephrine.

What the research says. A 2015 review concluded that tyrosine seems to help cognitive performance mainly in short-term stressful or demanding situations, and only when the body's messenger chemicals are temporarily depleted; its usefulness for treating any condition seemed limited.^[16] Most of those studies were in young adults.

Good to know. Tyrosine is also a building block of thyroid hormone. Talk to your doctor before use if you have a thyroid condition or are under a doctor's care.

DMAE (dimethylaminoethanol, from DMAE bitartrate)

A small nitrogen-containing compound, 2-(dimethylamino)ethanol, that is chemically related to choline and occurs naturally in small amounts in oily fish such as sardines and anchovies. In supplements it is usually supplied as the bitartrate salt.

What the research says. There is no good-quality research on DMAE and memory or attention in healthy adults, and we make no claim for it here.

Good to know. Not enough is known about its safety in pregnancy or breastfeeding, so it should be avoided then. Talk to your doctor before use if you are under a doctor's care.

Rhodiola rosea root extract

A plant known as arctic root, golden root or rose root that grows in cold regions and at high altitude in Europe, Asia and North America. The root is the part used.

Traditional and everyday use. A long history of use in Russia, Scandinavia and other parts of Europe for fatigue and work performance.

What the research says. In a double-blind crossover study of 56 healthy young physicians on night duty, one tablet a day of a standardized extract was associated with better scores on tests of mental fatigue during the first two weeks.^[17] The National Institutes of Health states there is not enough reliable evidence to say whether rhodiola is useful for any health-related purpose.

Good to know. Possibly safe for up to 12 weeks; side effects reported include dizziness, headache, trouble sleeping and dry mouth. Little is known about safety in pregnancy or breastfeeding. Talk to your doctor before use if you are under a doctor's care.

Ginkgo biloba leaf extract

An extract of the fan-shaped leaves of the ginkgo tree, a species so ancient it is called a living fossil, planted along city streets across the world. This is the herbal extract, a different thing from the homeopathic dilution of ginkgo found in some sprays.

Traditional and everyday use. Ginkgo leaf extract has been sold as a "memory herb" for decades.

What the research says. In the largest trial to date, 3,069 adults aged 72 to 96 took 120 mg of a standardized extract twice a day for a median of 6.1 years and declined at the same rate as the placebo group in memory, attention, language and every other domain measured.^[18] The National Institutes of Health states there is no conclusive evidence that ginkgo is helpful for any health condition.^[19]

Good to know. Ginkgo may increase the risk of bleeding in people who take anything that thins the blood; fresh ginkgo seeds are toxic. Talk to your doctor before use if you are under a doctor's care or are due for surgery.

Huperzine A (from the club moss Huperzia serrata; the label prints "Club serrata")

A purified alkaloid isolated from a Chinese club moss. It slows the enzyme that breaks down acetylcholine, so it acts on the nervous system in a way most botanical ingredients do not, and it is the one ingredient on this label that behaves more like a drug than like a food.

Traditional and everyday use. The moss has a history of use in Chinese herbal practice; the purified compound is a twentieth-century isolate.

What the research says. The research on huperzine A has been done in people with a diagnosed condition, not in healthy adults, so none of it can be cited in support of this product and we make no claim for it.

Good to know. Because it acts on acetylcholine it can cause nausea, sweating, a slow heartbeat or muscle twitching, and it can add to the effect of anything else that acts on the same system. Not for pregnancy or breastfeeding. Talk to your doctor before use if you take anything for your heart, your breathing or your nervous system.

*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. This information does not constitute medical advice and it should not be relied upon as such. This product is not a substitute for medication or other treatment prescribed by a physician or health care provider. Consult your doctor before starting any dietary supplement.

9. 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 product will improve your memory.
• That it will prevent, delay, slow or reverse dementia or Alzheimer's disease.
• That it offsets alcohol, sugar, processed food, or any drink or food named on this page.
• That it can replace a prescribed medicine, or make a medication review 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 liquid is absorbed better than a capsule. The seller says so; no published comparison of this product exists.

Things we can say honestly:

• It is a liquid dietary supplement, and every ingredient is listed above: four with the amount printed on the label, eleven inside two blends without individual amounts.
• The vitamins and choline in it are real nutrients with real Daily Values. Trials of B vitamins in people who are not short of them have found little or no effect on thinking; a blood test, not a bottle, tells you whether you are short.
• The price, shipping and the seller's 30-day exchange-or-store-credit policy are exactly what is written on the order page. Nothing more, and no promise made elsewhere overrides them.
• 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 doctor.

10. 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?

Ordinary coffee is not an established risk factor for cognitive decline, and reviews generally find neutral to modestly favourable associations. 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.

Should I stop my sleeping tablet or my anxiety medication?

Not on your own, and not because of an advertisement. Some of these drugs cause seizures or severe rebound symptoms if stopped abruptly. Take your full medication list to your doctor or pharmacist and ask whether anything on it is a poor fit for your age. See section 4.

Is this product a treatment for Alzheimer's or dementia?

No. It is not a treatment for any disease. If you or a family member is facing a diagnosis, the people to talk to are your doctor and a support organisation such as the Alzheimer's Association helpline listed above.

Is the folate line on the label a mistake?

The label prints "7.5 mg" and "50 %" side by side. The US Daily Value for folate is 400 mcg, so 50 % would be 200 mcg and 7.5 mg would be 1,875 %. One of the two figures is wrong; we do not know which. The other three vitamin and nutrient lines agree exactly with the Daily Value table. Ask the seller before you rely on either figure.

Why does this page talk about medicines if the product is not one?

Because one of our headlines pointed at "5 prescriptions", and you deserve to know what was behind it. Nothing in section 4 is advice to change a medicine, and the product is not an alternative to any of them.

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 5, 6 and 7 requires you to buy anything or trust us. If this page and our headlines disagree, believe this page.

Does this page cost anything?

No. It is free, 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 title. For general information, the National Institute on Aging (nia.nih.gov) and the Alzheimer's Association (alz.org) publish plain-language material and sell nothing.

References

These are the sources behind the claims marked with a number above. Most 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.
