The Trials Weighed Every Dose. This Liquid Prints 1,470 Milligrams and No Amounts.

Neurologic is a 32-ounce bottle from Liquid Health of Mesquite, Nevada, poured two tablespoons at a time. I set each of its eleven blended ingredients beside the study that measured it, and wrote down the distance between them.

A man in his sixties reading printed pages on his back steps at dusk

Warren Hadley is the pen name of this desk.

The reader mentioned below is a composite drawn from letters we received; names and identifying details have been changed.

Everything about the product, from the amounts to the label wording, the policies and the reviews, comes from the seller's own pages and label photographs, read on September 4, 2026.

The small photos beside the reviews are illustrations, not the reviewers.

I read supplement labels at a table in a room with too many windows.

The morning light is good for small print, and most of the print I read is small.

This month the bottle on the table was amber glass, 32 ounces, with a red name on the front.

I turned it around before I read the front, the way I always do.

Four lines on the back have a number and a percentage next to them.

Then come two boxes.

One box weighs 815 milligrams and holds six names.

The other weighs 655 milligrams and holds five.

1,470 milligrams, eleven names, and not one amount.

That's legal, and plenty of labels do it.

But it changes what a careful reader can know.

A study tells you exactly what it gave people. A blend tells you only what everything weighs together.

So I did the one thing a blend leaves open to you.

I printed the studies behind each of the eleven names and laid them out beside the bottle, one page at a time.

Some names have a large trial behind them.

Some have a small one, in the wrong age group.

Some have nothing useful at all in healthy adults.

And one name works differently from the other ten, which is why it gets its own section below.

What I found isn't a scandal. It's a distance, and I'd rather you knew its size before you buy.

The Grocery List, the Calendar and the Spare Room

Let's start somewhere that has nothing to do with a bottle.

Let's start in your house, on an ordinary Tuesday.

You write a grocery list on Sunday night.

On Monday you're standing in the cereal aisle, and the list is on the kitchen counter at home.

You know there were six things on it.

You can remember four.

A man in his sixties with a basket in a supermarket aisle, trying to remember what he came for
*Six things on the list, four in the basket, and the list itself on the counter at home.*

Or it's the calendar on the side of the fridge.

The haircut is on Thursday, you wrote it there yourself, and on Thursday morning you're halfway through the lawn.

And then there's the spare room.

You walk down the hall with a clear purpose, you step through the door, and the purpose stays behind in the hall.

You stand there, look at the bed, look at the closet, and come up empty.

Sound familiar?

If it does, you're in very large company, and most of that company is perfectly fine.

Here's the thing I want to say plainly before anything else.

A lost item on a grocery list is a busy morning, not a verdict.

An older married couple laughing over a paper calendar at a table in a glassed-in sunroom
*Most houses have a morning like this one: two cups, one calendar, and a date nobody wrote down.*

The people in this part of the page are composites too, drawn from the same letters as the reader with the bakery.

None of them is quoted, and none of them is credited with any result.

Picture a married couple in their late sixties, in a sunroom much like the one I read in.

They go over the week's calendar with the first cup of coffee, the way some people read the paper.

She keeps the dates.

He keeps the list of what's running low in the pantry, and he keeps it in his head, which is where the trouble starts.

On a good morning they laugh about it.

On a tired morning, after a short night, it's less funny, and he'll say so.

Notice what changes between those two mornings: not the man, just the night before it.

That's the first honest thing to know about the grocery list and the spare room.

They're affected by sleep, by rushing, by doing three things at once, and by how much is on your mind that week.

A man in his sixties stepping into a spare bedroom, pausing, and turning back toward the hall
*The spare room: in with a purpose, out with a shrug. Almost everyone has made this trip.*

So is walking into a room and forgetting why a sign of something?

On its own, it's one of the most ordinary moments a person has, at any age.

A doorway is a break in whatever you were doing.

It feels as if the errand got set down in the hall, and a break is exactly where small errands go missing.

And the name that won't come, then comes an hour later?

Same family of moment.

You're reaching for a word while you're talking, watching the road and holding the rest of the sentence.

Then you're washing a plate, nothing is asked of you, and there it is.

Nothing in this page is about fear, and nothing in it should make you worried about a grocery list.

It's about something smaller and more practical.

If you're going to add one more thing to your morning, you should know exactly what it is.

Why the Lists on the Fridge Only Go So Far

Most of us already have a system, whether we call it one or not.

A pad on the fridge, a hook by the door for the keys, a phone that buzzes before the dentist.

Those work.

Honestly, they're the best tools in the house for what they do.

Two halves: a notepad on a refrigerator door, and keys hanging on hooks by a front door
*Two of the best memory tools ever made cost about three dollars together.*

But notice what they do.

They hold the information for you, so you don't have to.

The list remembers the eggs.

The hook remembers the keys.

That's a fine arrangement until the list stays on the counter.

Or until the question isn't where the keys are, but how sharp you feel at the table at nine in the morning.

So what else do people usually try?

The usual advice, and it's good advice, goes something like this.

  • Sleep a proper night, because a short one shows up the next morning.
  • Drink water through the day, not only coffee.
  • Walk, even if it's just to the mailbox and back twice.
  • Eat more vegetables, beans, fish and olive oil, and less out of a packet.
  • Keep talking to people, the neighbor included.

There's real research behind some of that.

In a Berlin study of 1,111 adults aged 60 to 89, about a third were short of water, and they did worse over time on a timed test of processing speed. [1]

That's an association, not a trial.

But a glass of water costs nothing, and it's the easiest item on this page.

Food is a more interesting story.

In a three-year trial of 604 older adults, one group followed a Mediterranean-style eating plan and the other simply ate a little less. [2]

Both groups improved their thinking scores.

The difference between the two plans was small enough that the researchers couldn't separate them. [2]

I like that result more than a flashy one.

It says the act of paying attention to your plate, week after week, seems to count for something by itself.

Two neighbours in their sixties talking across a low garden fence beside a vegetable bed
*Two neighbours, one fence, and a conversation about tomatoes that ran twenty minutes longer than planned.*

Picture two neighbors across a low fence on a Saturday.

One is on his knees in the tomato bed, and the other has come out with a mug and nowhere to be.

They swap the same things men swap across fences.

Who forgot the recycling day, whose wife found the car keys in the freezer, and which one of them read about a bottle in the newspaper.

That conversation is worth something on its own.

Company, a laugh and a Saturday with nowhere to be are on nobody's label, and most of us are glad of them anyway.

But here's where the usual advice runs out for a lot of readers.

You can do every item on that list and still want to know about the bottle your neighbor mentioned.

That's a fair question, and it deserves a straight answer rather than a sales pitch.

So what can a bottle add, if anything?

That depends entirely on what's in it and how much, and that's the rest of this page.

One bottle, one label, and one reader who asked the right question first.

Let's go and look at it.

Thirty-Two Ounces From Mesquite, Nevada, Two Tablespoons at a Time

The bottle is heavy, amber glass with a metal cap, about the size of a bottle of maple syrup.

Thirty-two fluid ounces is thirty-two mornings at two tablespoons.

It's called Neurologic.

It's made by Liquid Health, a company in Mesquite, Nevada, that has sold liquid vitamins for years.

The flavor is berry pomegranate.

It goes in the refrigerator once it's open.

The company publishes a street address, a phone number you can call or text, an email and its customer-service hours.

It also prints its whole Supplement Facts panel on its own product page, at a size you can read.

That's more than most brands in this aisle will show you, and every number below comes off that panel.

A reader sent me a photograph of this same bottle in April, standing in his refrigerator door between the milk and the orange juice.

He keeps the books for his wife's bakery and reads invoices before the sun is up.

He'd been pouring it for five months.

He wanted to know one thing: how much of what he was pouring was actually in there.

A man in an apron going through invoices at a steel table in a bakery back room before dawn

It's the right question.

This page is my answer to it, and for most of the bottle the answer is that nobody can say.

Two Tablespoons, Every Line in Order

Here is the whole panel for one serving of two tablespoons.

Read it the way you'd read the back of a cereal box, top to bottom.

  • Vitamin E, 7.5 mg, printed as 50 percent of the Daily Value
  • Folate, printed as 7.5 mg and as 50 percent of the Daily Value
  • Vitamin B12, 400 mcg, printed as 16,667 percent
  • Choline, 100 mg, printed as 18 percent
  • A "Memory and Focus Blend" of 815 mg: aloe vera juice, acetyl-L-carnitine, alpha GPC, phosphatidylserine, L-theanine, alpha lipoic acid
  • A second blend of 655 mg, named on the label for alertness: L-tyrosine, DMAE, rhodiola root extract, ginkgo leaf extract, huperzine A

Five calories, one gram of carbohydrate, zero sugar.

The label says vegan, non-GMO, cold processed, third-party lab tested and made in the USA.

What does the front of the bottle say it's for?

One sentence, and here it is.

A powerful blend to promote mental acuity in everyday life & brain health over time.

— Liquid Health, front label of the bottle

"Promote" is a soft verb, and it's the right one for a supplement.

The label is more careful than the website, and that's usually how it goes.

What a Proprietary Blend Tells You, and What It Leaves Blank

A proprietary blend lists names in order of weight, heaviest first, and prints one total for the group.

That's all the law asks of it.

Think of it like a grocery bag with a weight on the receipt and no itemized list.

You know what's in the bag, and you know the bag weighs 815 grams, but not how much of that is the eggs.

So in the first box, aloe vera juice weighs the most and alpha lipoic acid the least.

In the second, L-tyrosine leads and huperzine A comes last.

Beyond that order, the label is silent.

You can't tell whether the phosphatidylserine is 300 milligrams or 3.

The order is a ranking, not a measurement.

Aloe vera juice is probably part of the liquid base, and it sits at the top of the first box.

That means the five names after it share whatever weight the juice leaves over.

An open ledger with handwritten columns, a pencil and reading glasses on a kitchen table

I'm not saying the amounts are small.

I'm saying no one outside the company can check them, including me.

I can tell you what the studies used. I can't tell you what the bottle gives you.

So the rest of this page goes one name at a time, and it says which of the two I'm doing.

Six Years, 3,069 Adults, 240 Milligrams a Day, and No Difference From Placebo

Ginkgo leaf extract is the famous one, and it has the biggest trial of anything in this bottle.

The Ginkgo Evaluation of Memory study gave 3,069 adults aged 72 to 96 a standard extract, 120 milligrams twice a day.

They were followed for a median of six years.

At the end, the ginkgo group had lost ground at the same rate as the placebo group, in memory, attention, language and everything else measured. [3]

Six years, three thousand people, and the same result as placebo.

The National Institutes of Health says plainly that there's no conclusive evidence ginkgo helps with any health condition. [4]

It also notes that ginkgo may raise the chance of bleeding in people who take anything that thins the blood.

Now set the trial beside the bottle.

The trial's daily amount, 240 milligrams, would be more than a third of the entire 655-milligram box, which ginkgo shares with four other names.

And ginkgo is fourth of five in that box by weight.

So whatever this bottle holds, the largest trial ever run on the plant gave its volunteers far more, for far longer, and found nothing.

That's the most useful sentence I can write about ginkgo, and it isn't flattering to anyone selling it, this bottle included.

Seventy-Eight Adults Aged 50 to 69, and a Placebo Group That Improved Too

Phosphatidylserine is the one with a trial in roughly the right age group.

Seventy-eight Japanese adults aged 50 to 69, all of whom had complained about their memory, took 100 or 300 milligrams a day for six months.

Scores went up in every group, including the placebo group.

Only the people who started with the lowest scores improved against their own starting point, mostly on remembering words after a delay. [5]

A man in his sixties on the phone at his kitchen table, taking notes

Remembering words after a delay is the grocery-list skill, if you think about it.

You read the list on Sunday, and you need it back on Monday in the aisle.

That's a modest result, honestly reported, and it's the best one in the first box.

The trial knew its dose to the milligram.

This bottle's phosphatidylserine sits fourth of six in the 815-milligram box, behind aloe juice, acetyl-L-carnitine and alpha GPC.

The label says it comes from non-GMO soy, which matters if soy matters to you.

One of the seller's store tags says there's no soy in it.

The panel says soy, so believe the panel and ask before you buy.

A Single Dose, Two Weeks of Night Shifts, and Short Demanding Spurts

L-theanine is the amino acid in green tea.

In Japanese men and women aged 50 to 69, the right age group for once, a single dose came with faster reaction times on an attention task. [6]

The summary of that study doesn't state the dose.

Neither does this label, so there are two blanks where a comparison would go.

A second theanine study did print its dose: 200 milligrams a day for four weeks, in 30 healthy adults with an average age of 48. [7]

Verbal fluency and a test of planning improved, and against placebo the verbal gain showed up mainly in the half who started lower.

Two of that study's authors worked for the company that supplied the theanine.

That's worth knowing, and it's the kind of thing a good study tells you itself.

A small glass of dark red liquid and a tablespoon on a kitchen counter in morning light

Rhodiola has one small study I'd mention.

Fifty-six young physicians on night duty took a standard extract, one tablet a day, and did better over two weeks on tests of calculation, short-term memory and concentration. [8]

Young physicians on night shifts is not a man of 65 at his kitchen table.

And the bottle doesn't say how much rhodiola sits in the second box.

L-tyrosine leads that second box by weight.

A review of the research found it seems to help in short, demanding situations, and mostly when the brain's messengers are temporarily run down. [9]

Outside those moments, the same review found its usefulness limited.

Four honest studies, four different kinds of volunteer, and not one amount on this label to set beside them.

One Name in the Second Blend Works Differently From the Other Ten

Huperzine A deserves its own sentence, so here it is.

It's a purified compound from a Chinese club moss, and it slows the enzyme that clears acetylcholine, one of the messenger chemicals nerves use.

The other ten names are nutrients, amino acids, plant extracts and a juice.

This one acts directly on the nervous system, in a measurable way, in small amounts.

In one small study, healthy adults took a single dose of 100 or 200 micrograms, twelve people per group.

Both doses slowed the enzyme in the blood, the higher dose held recall steady across sessions, and neither improved overall performance on the test battery. [10]

Micrograms, not milligrams, and last in the box by weight.

Being last tells you it's the lightest of the five names in the second box.

It doesn't tell you how light, and for this compound the amount is the whole conversation.

That's a reason to talk to your pharmacist or clinician before you start, not a reason to be impressed.

Bring the ingredient guide from the foot of this page, so they can see every name in the bottle.

Five Names With Nothing Useful to Report in Healthy Adults

Then there are the ones where the pile of printed pages stays empty.

Acetyl-L-carnitine, alpha GPC, alpha lipoic acid and DMAE have no useful evidence in healthy adults that I could set beside this label.

Aloe vera juice is probably part of the liquid base, and nobody sells it for memory.

That makes five of the eleven names with nothing to compare, before we even get to the missing amounts.

So the honest summary of the blends is short: real ingredients, real research on a few of them, and no way to tell how much of any of them you're getting.

What Has Been Studied, Put in Plain Words

Let's stop and gather it up, because that was a lot of names.

If you asked me across the kitchen table what's actually been studied, here's what I'd say.

Notice the word I keep using: studied.

Not promised, not settled, and not what you'll feel on day three.

So what does that add up to for your grocery list?

A few of these names have been tested for the kind of everyday recall and attention a busy morning asks for, at amounts this label doesn't print.

That's a real reason to be curious, and it's not a reason to expect anything in particular.

If that sounds like faint praise, it's meant to be exact praise.

You deserve to know which is which before a bottle goes in your door.

That's the bottle on its own, at a size you can see.

Now the part of the label you can check at the kitchen table with a pencil.

Where the Arithmetic Works, and the One Line Where It Doesn't

Four lines carry an amount and a percentage of the Daily Value.

Those are the only four you can hold up against a published table.

The Supplement Facts panel of Neurologic as published by the seller
*The panel, as the seller publishes it. Four lines with numbers, two boxes without.*

Vitamin E: 7.5 mg is exactly 50 percent of 15 mg.

B12: 400 mcg is exactly 16,667 percent of 2.4 mcg, the Daily Value the FDA publishes. [11]

Choline: 100 mg is 18 percent of 550 mg.

Three lines add up to the digit.

The folate line reads "7.5 mg" and, next to it, "50 %."

Those two figures can't both be right.

The Daily Value for folate on a US label is 400 micrograms, so fifty percent is 200 micrograms.

And 7.5 milligrams is 7,500 micrograms, which would be 1,875 percent.

Three lines add. One doesn't.

It's a misprint, either the amount or the percentage, and I won't guess which in print.

The company's phone number is on the bottle, and asking costs nothing.

Is 7.5 milligrams of vitamin E worth anything on its own?

A trial gave 6,377 healthy women aged 65 and older 600 IU on alternate days, far more than this, and found no benefit for thinking over nearly ten years. [12]

The B12 figure looks generous and means less on its own than it seems.

Absorbing B12 from food gets harder with age, and the National Institutes of Health says somewhere between 3 and 43 percent of older adults living at home run short, depending on how it's measured. [13]

The B12 in a supplement doesn't need the stomach's help to be released, the way the B12 in food does. [13]

That's a genuine point in favor of any B12 supplement, this one included.

A Cochrane review of fourteen trials in 27,882 adults with normal thinking found that B-vitamin supplements probably do little or nothing for overall thinking over five years. [14]

That review is about people who are not short of these vitamins.

A real shortfall of B12 gets more common with age, and a blood test answers that question in a week.

Choline is the line I'd point a friend to.

In 1,391 adults aged 36 to 83, the ones who ate more choline scored better on verbal and visual memory tests. [15]

That's food, not a supplement, and an association, not a trial.

But it's a real nutrient with a real amount printed beside it, and on this label that makes it the exception.

A Liquid Absorbs Better? No Comparison Has Been Published

The seller makes one more claim, and it's the one that justifies the whole format.

Its page says the liquid's absorbability is "vastly better" than tablets, capsules and chewables.

This means your body will readily take in all the vitamins we've sourced and formulated for you.

— Liquid Health, from the seller's own product page

I looked for a published comparison of this liquid against a capsule, or anything measuring how much of it reaches the blood.

I didn't find one, and the company doesn't publish one either.

The advantage of a liquid isn't chemistry. It's behavior.

It lives in the fridge door, it doesn't need to be swallowed dry, and you taste it, so you notice when you've skipped it.

A Normal Day in a House With the Bottle in the Door

So what would a day look like with this bottle in it?

Let's go back to the couple in the sunroom and walk through an ordinary Wednesday.

The inside of a refrigerator door with milk, juice, jam and eggs
*The door shelf is where things get remembered. That's the whole argument for putting a bottle there.*

Seven o'clock, the kitchen.

He opens the fridge for the milk, and the amber bottle is standing right there in the door.

He shakes it and pours two tablespoons into a small glass.

He drinks it cold, caps it, and shuts the door in about twelve seconds.

A man's hands lifting a small glass of dark red liquid at a kitchen counter and setting it down

Seven fifteen, the sunroom.

Coffee, toast, and the calendar laid flat on the table between them, the way they do every morning.

An older couple in a glassed-in porch in the morning, the man writing on a notepad while his wife looks on
*The calendar gets read out loud, and the grocery list gets written down. Two small habits, one table.*

She reads the week out loud.

He writes the grocery list on paper this time, not in his head, and he sticks it to the fridge before he leaves the room.

A man in his sixties writing one item on a notepad stuck to the refrigerator door
*The list goes on the fridge door, a few inches from the bottle. Both of them get seen every time the door opens.*

Is the bottle doing anything in that scene?

Honestly, I can't tell you, and neither can he.

What I can tell you is what the scene is made of.

A regular breakfast, a paper list, a calendar read out loud, and twelve seconds at the fridge door.

Ten o'clock, the garden.

The neighbor comes to the fence, and the two of them argue about tomatoes for twenty minutes.

Two o'clock, the spare room.

He walks in for the extension cord, stops, and can't remember why he's there.

It still happens. It happens to everybody.

He goes back to the hall, sees the lamp that needed the cord, and laughs at himself.

That's an honest day, and I'd rather describe one than sell you a perfect one.

Nothing in a bottle retires the spare room.

The reader with the bakery lives a version of the same day.

He takes his two tablespoons before the coffee, with a slice of toast, which was his wife's rule, not the label's.

  • A real breakfast before the invoices, on the days he knows they'll be thick.
  • Water on the table, refilled when the first column is done.
  • Two tablespoons with the toast, every day, whether or not a hard morning is coming.
  • A hard stop at sixty minutes, then five minutes at the back door doing nothing.
A man in his early sixties looking up from a ledger at his kitchen table before dawn

Three of those four things cost nothing.

The fourth is the one he pays for, and he'd tell you that's the right way round.

Five months in, he says less has changed than the label suggests, and more than nothing.

The morning when a column won't add still shows up after a bad night, because that morning is mostly made of the night before it.

And he'll tell you himself he can't separate the bottle from the toast, the water and the sixty-minute rule.

That's not a testimonial.

It's a grown man refusing to overclaim on his own behalf, and I trust it more than five stars.

Who It Suits, and Who It Doesn't

So is this bottle for you?

Here's how I'd sort it, honestly, if you were sitting across from me.

This is worth a look if:

  • You've failed at capsules before, for reasons of habit rather than belief.
  • You want something you'll see every time you open the fridge, and you'll actually use.
  • You like a morning routine with a fixed spot in it, right next to the milk and the grocery list.
  • You can hold two ideas at once: real ingredients, and amounts nobody outside the company can check.
  • You're in the United States, because the seller ships nowhere else.

Give it a miss if:

  • You want something that acts on a condition a clinician has named.
  • You want to know exactly how much ginkgo, theanine or huperzine A you're getting. This label won't say.
  • You have a soy allergy. The phosphatidylserine comes from soy, whatever the store tag says.
  • You dislike berry flavors. One of the eighteen reviewers took a star off for exactly that.
  • You take anything daily and haven't shown the label to your pharmacist yet.
  • You're pregnant or nursing, or under a clinician's care and haven't asked first.

Three Honest Objections: The Price, the Taste and the Wait

Every reader who writes to me about a bottle has at least one of these three.

They're good objections, so let's take them one at a time.

"It costs more than a bottle of vitamins from the pharmacy shelf."

It does, and a plain B12 tablet would give you the B12 for less.

What you'd be paying for here is the rest of the panel and the format.

If the format is the thing that gets you to take anything at all, that's worth something; if you never forget a capsule, it may not be.

The current price is shown on the seller's site rather than here, because prices change.

I'm not going to print a number that goes stale.

"What if I can't stand the taste?"

One of the four reviews below says exactly that, and she still gave it four stars.

The seller's own questions page says you can mix the serving into a drink.

A splash of juice or a glass of water is the usual answer, and it costs you nothing to try.

A hand pouring water into a small glass of dark red liquid on a sunroom table
*Two tablespoons and a splash of water. If the taste is the problem, this is the usual answer.*

"How long before I'd know anything?"

Longer than you'd like, and shorter than the studies.

The phosphatidylserine trial ran six months, and the placebo group improved too. [5]

A bottle is a month, so if you try it, decide in advance to give it a season and judge the habit, not a single week.

The fair test of a daily habit is a quarter of a year, not a Tuesday.

And keep the grocery list on the fridge the whole time, because that part works on day one.

Six Things This Bottle Will Not Do

  • It will not tell you how much of any of its eleven blended ingredients you're getting. The label prints two totals and no amounts.
  • It will not match the ginkgo trial. That trial gave 240 milligrams a day for six years and found no difference from placebo.
  • It will not act on any condition a clinician has named. It's a dietary supplement, and that's all it is.
  • It will not make up for four hours in bed. Nothing sold in a bottle does.
  • It will not tell you whether you're short of B12. Only a blood test does that.
  • It will not remember the grocery list for you. The pad on the fridge still does that best.

If that list annoys you, I'd rather you were annoyed now than in a month.

The Seller's Thirty Days, in Plain Terms

What happens if I buy it and don't like it?

The seller's policy covers exactly that, and it's worth reading before you click.

Within thirty days of buying on Liquid Health's own site, you can call or write for any reason: taste, packaging or effect.

The seller will exchange it for another product or give you store credit.

It's an exchange or a store credit, not your money back.

And it covers only bottles bought directly from the seller, not from another store.

The bottle is also sold in a couple of big retailers, the seller says, but its policy only covers the direct purchase.

That's why the direct site is the only place this page links to.

What Readers Ask Before Their First Bottle

Questions readers ask

Is this medicine?

No. It's a dietary supplement, and no regulator has approved it for any health condition.

Why doesn't the label say how much ginkgo or phosphatidylserine is in it?

Both sit inside proprietary blends, which only print a total weight and the names in order.

Is there enough ginkgo in it to match the big trial?

Nobody outside the company can say. The trial gave 240 milligrams a day and found no difference from placebo after six years.

Should I ask someone about huperzine A?

Yes. It acts on the nervous system directly, so show the ingredient guide to your pharmacist or clinician first.

Why doesn't the folate line add up?

I don't know. The other three lines match the Daily Value table exactly, so call the number on the bottle.

How long does a bottle last?

Thirty-two mornings at two tablespoons. Call it a month.

Can I mix it into something?

The seller says yes, into a drink. Water or a splash of juice works.

Will it help me remember the grocery list?

I can't promise that, and be wary of any page that does. A few of its ingredients have been studied for everyday recall at amounts this label doesn't print.

Eighteen Reviews on the Seller's Page, and the Three-Star One Says the Most

The seller's own page carries eighteen reviews.

Thirteen are at five stars, four at four and one at three.

Fourteen carry the review platform's buyer mark.

One five-star review says the writer never received the product, which tells you how much a star count is worth.

Two mention a family member's health, and I've left those out on purpose.

I've kept four below, all with the buyer mark, and I deliberately kept the lukewarm ones.

NeuroLogic is one of my go-to brain health supports. I will always have it in my health cupboard. I've tried many supplements - most I wouldn't buy again. This one I've bought several times, 3 or 4 bottles each time.

Taste is very tolerable. We have almost finished the bottle. Have not seen a difference that we can tell.

This is a great combination. Unfortunately, I am having a bit of trouble getting used to the taste. I do appreciate that they have tried to give this a good flavor; I am just not into it.

The product I purchased seems to be effective and works. So far so good. But need more time to feel how effective it actually is. But would buy this product again.

The most useful one on that page is the three-star review.

A whole bottle, finished, taste fine, and no difference the writer could point to.

That's what an honest account of a supplement usually sounds like.

Some people notice something and some don't, and nobody can tell you in advance which one you'll be.

Everything Above, in Sixty Seconds

  • The grocery list, the calendar and the spare room are ordinary moments, and a paper list still beats any bottle at them.
  • Water, a regular plate and company cost nothing, and there's research behind the first two. [1] [2]
  • A 32-ounce liquid from Liquid Health, a Nevada company that publishes an address, a phone number, an email and its full label.
  • Two blends, 1,470 mg, eleven names, and no amount for any of them.
  • Ginkgo: 3,069 adults, six years, 240 mg a day, no difference from placebo. [3]
  • Phosphatidylserine: 78 adults aged 50 to 69, a modest result only in those who started lowest. [5]
  • Theanine, rhodiola and tyrosine: small studies, in volunteers unlike you or at doses this label doesn't print.
  • Huperzine A acts on the nervous system directly; ask your pharmacist before you start.
  • Four lines with numbers; three add up exactly, and the folate line doesn't.
  • A thirty-day exchange or store credit, not a refund; ships within the United States only.

The Bottle, the Blends, and What You Can Know Before You Buy

The reader with the bakery is on his sixth bottle.

He still has a morning when the column won't add after a bad night, and anything that promises otherwise isn't being straight with you.

The couple in the sunroom still lose a date now and then.

The list on the fridge catches most of what the calendar misses, and they laugh about the rest.

What changed for the bakery reader is twelve seconds at the start of the day, in front of an open fridge.

And he knows exactly what he bought, including the eleven names nobody weighed for him.

One amber bottle for the refrigerator door, sold from Mesquite

Neurologic

A liquid blend of vitamins, choline and eleven botanical and amino-acid ingredients, poured out two tablespoons at a time from an amber glass bottle.

P.S. If you take one thing from this page, take the distance between the studies and the blends: the trials weighed every dose, and this label weighs two boxes.

P.P.S. If names or lists have been slipping for a year, book the blood test before you buy anything. [14] A bottle takes a month and still doesn't answer a question a laboratory answers in a week.

P.P.P.S. And if you do buy it, put it in the door next to the grocery list, not the back of the shelf, because the whole case for this format is that you can't open the milk without seeing it.

Every line on the panel, both blends included, is written out in the ingredient and advertising guide linked at the foot of this page: what each name is, what the research does and doesn't show, and at what amount.

Print it and take it to the pharmacy counter if you take anything daily; huperzine A is the name to point at.
