Across and Down: A Bottle Called GoldenBrain, Solved Like a Sunday Puzzle

GoldenBrain is a supplement sold online in two, three or six bottles. I wrote what its label says across the top and what its four ingredients have been shown to do down the side, and looked for where the letters cross.

This is a paid advertisement. Sponsored by GoldenBrain Research (seller); orders are processed by BuyGoods.

Nora Whitfield is the name this desk signs with, and the Sunday puzzle in this story is a habit its writers share.

What this page says about the bottle comes from the seller's own pages, its list of ingredients, its refund terms and the published studies on each ingredient, all read in October 2026.

Every Sunday morning I fold the paper to the puzzle page, pour the coffee, and sharpen a pencil.

I've done it since I was a young teacher, and I'm long retired now.

The rules haven't changed.

The clues run across and the clues run down, and a letter only counts when it works in both directions.

A word that fits across but breaks the word going down is a wrong answer, however good it looks.

That rule has turned out to be useful for far more than puzzles.

You probably have a Sunday habit of your own.

A word game on the phone, a jigsaw on the dining table, a card game after church, the sports page read front to back.

And you probably know the moment I'm about to describe, because it happens to all of us at that table.

Seven letters, "Actress in the lighthouse film," and you can see her face and the color of her coat.

The name sits right behind your teeth and won't come out.

You move on, fill in the squares around it, and twenty minutes later it drops in on its own.

The name always arrives. It just doesn't take requests.

This fall my sister-in-law mailed me a printout of a web page with a bottle on it.

The bottle was called GoldenBrain, and the page said it was for memory and focus.

On the printout she'd written, "You're the puzzle person. Is this real?"

So I did what I do with a hard clue.

I wrote the bottle's words across the top of a sheet, and I wrote what I could actually find out going down the side.

Across: what the label and the sales page say, in their own words. Down: what each ingredient has been shown to do in a published study, in whom, and at what amount. A letter only counts where the two agree.

This page is that sheet, filled in so you can check my letters.

It isn't a verdict, and it isn't medical advice.

It's a puzzle person's reading of a bottle.

By the end you'll know which squares are solid, which are penciled in lightly, and which I had to leave blank.

Fifty Years of Sundays, One Pencil

I taught seventh-grade English for thirty-one years, and the crossword was the one thing I never graded.

It was mine.

My mother did it before me, in ink, which I've never had the nerve for.

Here's what the puzzle teaches, if you let it.

A clue is not an answer. It's a hint about an answer, written by somebody who wants you to work for it.

"Memory + Focus" on a bottle is a clue in exactly that sense.

It tells you what the maker wants you to think about, and it tells you nothing about what will happen.

A good-looking word can still be wrong. I've written SALMON where the answer was SARDINE more times than I'll admit.

It fit the clue; it didn't fit the crossing letters.

And the crossings are where the truth lives. A square is only solid when the word across and the word down both want the same letter.

So that's how I read anything with a price on it now.

Across, I copy what the seller says, word for word, without arguing.

Down, I go find what's been measured, and I write the size of each study, because ten people and ten thousand aren't the same square.

Then I look for the crossings.

Where they agree, I press hard with the pencil.

Where they don't, I leave the square light, or blank, and I say so.

The Clue Everyone Over Sixty Knows

Let's start where my sister-in-law started: not with the bottle, but with why she mailed it.

What kind of slips are we talking about? The ordinary ones.

The name of the actress, the word you want in a sentence, the reason you walked into the pantry.

You put the glasses down in a room you weren't in.

You tell the same story to the same neighbor, and you see it in her face before you finish.

You know the capital of a country you taught for thirty years, and for one awful second you don't.

Is that something to worry about? For most of us, no.

It's the ordinary forgetting of a full life and a busy head, and names are the hardest thing of all to hold, at any age.

A name is a label with no meaning attached, and the mind prefers things that mean something.

That's why the clue "Actress in the lighthouse film" is harder than "Opposite of under."

A blank square is not a failing grade. It's a Sunday with the coffee not yet finished.

I'm not going to tell you those moments are dangerous, because for most people they aren't.

And I'm not going to tell you a bottle makes them go away, because nothing on any shelf does that.

But I understand the printout in the envelope.

So why does someone buy a bottle with "brain" in the name? Because the squares feel slower to fill than they used to.

Because a sister worries, and buying something is a way of saying so.

Those are decent reasons to be curious.

They are not reasons to skip the crossings.

What Already Fills the Grid

Before I pencil in anything new, I look at what's already working on the page.

Most of us have a system for the slips, even if we've never called it one.

Do lists work? For the pantry and the pharmacy, yes.

The index card in my purse gets me through the grocery store nine times out of ten.

Do routines work? For the glasses and the keys, better than anything.

The glasses live on the windowsill above the sink, and when they aren't there, I know exactly which two rooms to check.

Does sleep work? You already know how different the Sunday puzzle feels after eight hours and after five.

The same goes for water, a walk, and a plate that looks more like a garden than a box.

I'll put those on the grid later, with their studies, because they belong there and they cost very little.

So where does the system stop? It stops at the thing you can't write on a card.

A list holds the errand; it doesn't hold the actress's name.

And that's where people start looking at web pages with bottles on them.

Every bottle on those pages has "memory," "focus" or "brain" in large letters.

That's exactly when the across-and-down habit earns its keep.

Wanting a little help is reasonable. Paying for help nobody measured is a word that fits the clue and breaks the crossing.

How I Read a Bottle Like a Clue

Four questions, every time, for anything I'd pay for monthly.

They're plain, and the answers are usually printed somewhere, if you look for them.

First: what exactly is in it? Not the picture, not the name. The list, and the amount next to each line.

Second: what does each line have behind it? A study of what, in whom, for how long.

And what that study measured: a blood test, a scan, an exercise test, or a memory test.

Third: does the amount match? A study of three grams tells you about three grams.

It tells you nothing about a capsule with no number printed on it.

Fourth: what does it cost, all in? Dollars, shipping, side effects, the months before you'd know anything, and the rules for getting your money back.

Across answers the first question. Down answers the second and third. The receipt answers the fourth.

One more thing before the grid.

I read the studies myself, and I'll tell you the size of each one and what it measured.

When a study is small, I'll say so.

When a study used an amount the bottle can't confirm, I'll say that too.

And when I couldn't find a study at all, I'll leave the square blank rather than guess at it.

Across: What the Label and the Page Say

Here's the top row, copied without argument.

1-Across: the name. GoldenBrain, sold by a company calling itself GoldenBrain Research, with orders handled by a payment company called BuyGoods.

The name is a name.

It goes in the top row as a clue, and it doesn't go anywhere else.

2-Across: the promise. The sales page calls it "a premium cognitive wellness formula designed to support healthy brain function, focus, memory, and mental clarity."

Those are the seller's words, and I've left them in the seller's quotation marks.

"Support" is a word the law allows on supplements, and it means less than it sounds like it means.

3-Across: the ingredients. The seller's references page names four, and I copied them exactly.

• L-arginine, as a base form and an alpha-ketoglutarate form in a two-to-one ratio.
• L-citrulline, as a hydrochloride and a malate.
• Beta-alanine.
• Niacin, which is vitamin B3.

4-Across: the amounts. This is the square I most wanted to fill, and I couldn't.

Nowhere on the sales page, the references page or the checkout does the seller print how many milligrams of anything are in a serving.

The page doesn't show a Supplement Facts panel at all.

It calls each bottle a thirty-day supply, and that's the only number about what's inside.

What about the "Scientific References" page? I clicked every link on it.

Each one says "View Scientific Reference" and each one opens the front door of PubMed, the government's medical library, with no particular study attached.

That's like a crossword clue that says "See dictionary."

So every study you'll read about below, I went and found myself.

Four across-clues: a name, a promise, four ingredients and a missing number. The missing number matters more than the other three.

The Price Grid: Two, Three or Six

Now the receipt, because I like to see the number before the arithmetic, not after.

Can you buy one bottle to try it? No.

The seller's page offers three packages, and the smallest is two bottles.

Here they are, as they appeared the day I read them.

• Two bottles for $158, which the page calls a sixty-day supply, plus $19.99 shipping. That's $177.99 all in, about $2.97 a day.
• Three bottles for $207, a ninety-day supply, shipping included. About $2.30 a day.
• Six bottles for $294, a hundred-and-eighty-day supply, shipping included. About $1.63 a day.

What about the "You save $780"? That's measured against a "normal price" of $179 a bottle that the seller prints and then crosses out.

Nobody on this page pays $179.

A crossed-out number is a clue the seller wrote for himself, and it doesn't go in my grid.

What goes in my grid is what leaves your account: $177.99, $207 or $294.

Anything else at checkout? One box worth reading twice.

The checkout offers "Save 10% when you Subscribe & Save," and the small print says that checking it means a shipment and a charge every month, billed as "BuyGoods."

You can stop it by phone, at (866) 838-5063, and the hours are printed there.

If you want one order and not a monthly one, leave the box empty.

Ten percent off is a clue. "Every month" is the answer. Read the crossing before you pencil it in.

Is $2.30 a day a lot? It depends on your grid.

It's less than the Sunday paper and more than a bag of apples.

What I'll say is that it's a known number, visible before you buy, and that counts for something.

Down: What Each Ingredient Has Been Shown to Do

Now the hard part of the puzzle.

Four down-clues, one for each ingredient, in the order the seller lists them.

For each I'll tell you what the best study I found measured, how many people were in it, how much they took, and for how long.

Keep 4-Across in mind the whole way: the bottle prints no amounts, so none of these doses can be checked against it.

1-Down: L-Arginine

What is it? An amino acid your body uses to make nitric oxide, a gas that relaxes blood vessels.

That's why it turns up in products for circulation, for the gym, and now for the brain.

What does the study say? This is the only down-clue with a thinking test behind it, so let's go slowly.

In Italy, seventy-two frail older adults with high blood pressure finished a four-week trial: thirty-five took L-arginine and thirty-seven took a placebo. ^[1]

The dose was 1.66 grams twice a day, about 3.3 grams in all.

At the end, the arginine group scored higher on a standard thirty-point screening test of thinking than the placebo group. ^[1]

So what's solid here? A real result, in people who were older, frail and hypertensive, over four weeks, at 3.3 grams a day.

Every one of those words is part of the answer, and none of them appears on the bottle.

Is there anything to be careful about? Yes, and I want to press hard with the pencil on this one.

In a trial at Johns Hopkins, 153 people who had just had a heart attack were given L-arginine or a placebo on top of their usual care. ^[2]

Six people in the arginine group died within six months and none in the placebo group, and the safety board stopped the trial early. ^[2]

The authors wrote that L-arginine should not be recommended after a heart attack.

If you've had a heart attack, this is not a bottle to open without your cardiologist's say-so. That square is black, not blank.

2-Down: L-Citrulline

What is it? Another amino acid, first found in watermelon, which the body converts into arginine.

It's often sold alongside arginine because of how it behaves in the gut.

What does the study say? Twenty healthy volunteers in Germany took different doses of citrulline, arginine or placebo, a week at a time. ^[3]

Citrulline at three grams twice a day raised the level of arginine in their blood more than taking arginine itself did. ^[3]

But none of the treatments improved how well their arteries widened on the test the researchers used for that. ^[3]

What about memory? I looked for a trial of citrulline alone, in older adults, with a memory or thinking test at the end.

I didn't find one I could stand behind.

So this square gets what I found: a blood-level result in twenty people, at six grams a day, and nothing about remembering.

3-Down: Beta-Alanine

What is it? An amino acid that builds up a buffer in muscle called carnosine.

If you've ever tried a pre-workout powder and felt your face tingle, that was beta-alanine.

What does the study say? Two small ones, and they point in slightly different directions.

In Buffalo, twelve adults averaging sixty took 2.4 grams a day or a placebo for twenty-eight days, then cycled to exhaustion. ^[4]

The beta-alanine group cycled longer, and five minutes after stopping, they didn't slow down on a color-word test the way the placebo group did. ^[4]

In Israel, twenty young soldiers took six grams a day for twenty-eight days during hard training. ^[5]

They shot more accurately, but on a mental arithmetic test done while tired, there was no difference from placebo. ^[5]

So what's solid? Twelve people and twenty people, both exercising hard, both at grams a day.

One study saw less mental slowing after exhaustion; the other saw no mental difference at all.

Neither one asked anybody to remember a name on a Sunday morning.

4-Down: Niacin

What is it? Vitamin B3, the one in chicken, tuna, peanuts and fortified cereal.

A severe shortage of it causes a disease with confusion as one of its signs, which is why it's been of interest to memory researchers.

What does the study say? This is the biggest study on the whole sheet, and it's about food, not pills.

In Chicago, 3,718 people over sixty-five filled out diet questionnaires and took thinking tests every three years for about five and a half years. ^[6]

Those who got the most niacin from food declined more slowly than those who got the least. ^[6]

The link was stronger for niacin from food than for niacin from supplements, and the top group was eating roughly 22 milligrams a day, about what two servings of chicken and a bowl of fortified cereal provide.

So what's solid? A large, long observation, in food, in people like us.

It's a reason to eat your tuna sandwich.

It isn't a trial of a capsule, and this capsule doesn't print how much niacin it carries.

Where the Letters Cross, and Where They Don't

Now the part of the puzzle I actually enjoy: holding the across row against the down column.

Where do they agree? The ingredients are real, and each one has been studied for something.

Three of the four are about blood flow, and a fourth is a vitamin your brain needs some of.

"Support healthy blood flow" is a square where the letter holds in both directions.

Where do they disagree? At the word "memory."

Across, it's the second word in the promise.

Down, I found one small trial that measured a thinking score, in frail hypertensive people, at a dose the bottle can't confirm.

That's a light pencil mark, not a solid letter.

And where is the square simply empty? At the amounts.

Every study above used grams of arginine, grams of citrulline, grams of beta-alanine.

A capsule holds a fraction of a gram, and the bottle doesn't say how many capsules make a serving or how much is in each.

So I can't tell you whether a day of GoldenBrain gives you the Italian dose, a tenth of it, or a hundredth.

A formula is a word. The amounts are the letters. Without the letters, you can't check the word.

Has anyone tested the bottle itself? Not that I could find.

No study has put these four ingredients together, in whatever amounts this bottle holds, in anyone.

That's common for products like this, and it's still worth saying out loud.

It's the one square I can never fill from my kitchen table, because nobody has written the clue.

What You Might Feel in the First Week

I promised the fourth question: the costs that aren't dollars.

Here's what these four ingredients are known to do in the body, so a surprise isn't a surprise.

The flush. Niacin above roughly thirty to fifty milligrams can make your face and neck go warm and red for half an hour.

It's harmless and it's startling, and whether it happens depends on an amount the bottle doesn't print.

The tingle. Beta-alanine in the gram range makes the skin of the face and hands prickle for a while after taking it.

Again, harmless, and again, it depends on the amount.

The lightheaded moment. Arginine and citrulline both relax blood vessels.

If you already take something that lowers blood pressure, or anything for the heart, the two can add up.

Standing up quickly and feeling the room tilt is the kind of thing to tell somebody about.

Three things you might feel, and a pharmacist who can tell you in five minutes which ones apply to you.

Why the pharmacist and not just the label? Because this label doesn't give amounts, and because the pharmacist can see the rest of your cabinet.

Take the bottle, or a printout of the ingredient list, and everything else you take daily.

Ask two plain questions.

• Does anything I take argue with amino acids that widen blood vessels, like arginine and citrulline?
• Is there any reason niacin or beta-alanine is a poor fit for me?

And if you've had a heart attack, ask the cardiologist, not the pharmacist, and ask before the first capsule.

Who Should Pencil It In, and Who Should Leave the Square Blank

Not every answer belongs in every grid.

It might make sense for someone who understands this is a circulation formula with a brain name, and wants to try it on those terms.

For someone who's already asked the pharmacist, and whose cabinet is simple.

For someone who can afford to find out that two bottles did nothing noticeable, and who will keep a one-line note every day to know.

And for someone who will write the delivery date on the calendar the day the box arrives, for reasons I'll get to.

It doesn't make sense for anyone who has had a heart attack without a cardiologist's explicit yes.

It doesn't make sense for anyone who takes blood-pressure medicine, nitrates, or a pill for erectile function and hasn't checked, because all of those work on the same blood vessels.

It doesn't make sense for someone who needs to know exactly how much of something they're taking, because this bottle won't tell them.

And it doesn't make sense for someone whose worry about memory is real and growing.

That worry belongs with a doctor, in a proper appointment, not in a package from a website.

A supplement is a small daily choice. It belongs in the grid only when you can see what's in it.

Sixty Days, Counted From the Doorstep

Here's the clue I always solve in red pencil: the refund terms.

They're the only part of a purchase that protects you if the rest of the puzzle doesn't work out.

What does the seller promise? Sixty days to ask for your money back, counted from the day the package is delivered, not the day you order.

That's a better clock than most, and I'll give it its due.

What do you have to do? Four things, and the order matters.

• Email the seller's support address with "Refund Request" in the subject line, inside the sixty days.
• Pack up every bottle you received, full, half-full or empty. The terms say all of them must come back.
• Mail them, with the packing slip and your name and order number, to a post office box in Ogden, Utah. The return postage is yours to pay.
• Wait. The seller says five to ten days after the box arrives for the refund to process.

What's the catch? Two, and a puzzle person spots them.

First, the same refund page advises using the product "for at least 3 months" before judging it, and the window closes at sixty days.

You can't do both.

If you want the refund option, you have to decide at about eight weeks, whatever the page says about three months.

Second, with six bottles, you're mailing six bottles back to Utah at your own cost, and shipping the first order wasn't refunded either way.

Write the delivery date on the calendar. Then count fifty days forward, not sixty, and write "decide" on that square.

Why fifty and not sixty? Because the bottles have to arrive in Utah, and you want a week of slack for the mail and for yourself.

The payment company, BuyGoods, also prints a sixty-day guarantee of its own at checkout, with a phone number.

Keep the order confirmation email; it has everything you'll need.

A Sunday With the Bottle in It

If you do try it, here's how I'd fit it into a week, so that the one new thing stays one thing.

When? With breakfast, after the pharmacist has said yes, following whatever the label says about servings when the bottle arrives.

A habit sticks best when it rides along with one you already keep.

What else changes? Nothing, if you can help it.

Same coffee, same walk, same bedtime, so the only new square on the page is the capsule.

How would you know if it's doing anything? One line a day, under the crossword.

• Did I take it, and did I feel anything after: warm face, tingling, lightheaded?
• How did I sleep, roughly?
• Did I walk?
• One sentence about the day: a name that came quickly, or one that didn't.

Thirty seconds, and at the end of eight weeks you have a record instead of a feeling.

Why write down the sleep and the walk? Because they move your Sunday more than any capsule, and if you don't write them down you'll give the bottle credit for a good night.

And on day fifty? Read the lines back the way you'd check a finished grid.

If the good days were the days you slept and walked, you have your answer.

If you can't tell, that's an answer too, and it's worth knowing before the window closes.

Squares That Cost Nothing

Before I fill in the last corner, here's the page I always add: the squares with the longest studies and the smallest price.

Water. In 1,111 adults aged 60 to 89, the third who were measurably short of fluid did worse over time on a test of how fast they processed information. ^[7]

A review of eighteen studies in adults over sixty found the same pattern linking too little fluid to poorer thinking scores. ^[8]

A glass of water beside the puzzle is the cheapest square on this page.

The plate. In a three-year trial of 604 older adults, people on a MIND-style diet and people who simply ate a little less both improved their thinking scores by about the same amount. ^[9]

Chicken, tuna and peanuts, by the way, are where most of us get our niacin, and nobody mails them back to Utah.

The evening glass. In British civil servants followed for thirty years, heavier drinking went with shrinkage of the hippocampus and slower word-finding, and light drinking showed no advantage over none. ^[10]

Less in the glass is a square with a thirty-year study behind it.

The walk and the puzzle itself. I don't need a study to tell me a walk and a crossword do me good, but I'll say it anyway: they're the two squares I'd fight to keep.

The cheapest squares have the longest studies. That's not a coincidence, and it's not a secret.

The Whole Puzzle on One Card

If I had to fit this sheet on one index card for my sister-in-law, here's what I'd write.

• Across: a name, a promise, four ingredients and no printed amounts.
• Across: the references page points to the front door of PubMed and nothing more.
• Receipt: $177.99 for two bottles, $207 for three, $294 for six; no single bottle; a subscription box at checkout to leave empty unless you want monthly charges.
• Down: arginine raised a thinking score in seventy-two frail hypertensive adults at 3.3 grams a day for four weeks. ^[1] A trial after heart attacks was stopped early for deaths. ^[2]
• Down: citrulline raised blood arginine in twenty volunteers at six grams a day; no memory test found. ^[3]
• Down: beta-alanine, in twelve and twenty people exercising hard, showed less mental slowing in one study and nothing in the other. ^{[4] [5]}
• Down: niacin from food, in 3,718 people over five years, went with slower decline. ^[6]
• Blank square: the bottle itself has never been tested, and none of the doses above can be checked against it.
• Black square: no one who has had a heart attack opens it without a cardiologist.
• Red pencil: sixty days from delivery; every bottle back to Utah at your cost; decide by day fifty.

Filling In the Last Square

I finished this sheet on a Sunday in October, with the actual crossword still half done beside it.

Here's where the puzzle landed.

The across row is clear: a name, a promise, four ingredients and a missing number.

The down column is honest but thin: four real ingredients, each studied for something, mostly blood flow, at doses in grams, in small groups.

One crossing holds, at "blood flow."

One is penciled lightly, at "memory."

And one stays blank, at the amounts, because nobody has written that clue.

Is that a reason to buy it or not? That's your square, not mine.

What I can tell you is the shape of the question: a known price, a sixty-day clock from the doorstep, a pharmacist's five minutes first, and a cardiologist's yes if your heart has a history.

Fill in what you can check. Leave light what you can't. Never ink a square because the clue was pretty.

I mailed the sheet back to my sister-in-law with the printout.

At the bottom I wrote, "It's a circulation formula with a brain name, and the amounts are missing. Ask your pharmacist. Then it's your call."

If you decide to try it, you now know what goes across, what goes down, and which day to write "decide" on the calendar.

If you decide not to, the water, the walk, the plate and the puzzle are still on the grid, and they don't come in packages of two.

Either way, I hope the actress's name arrives before your coffee goes cold.

Mine did, by the way.

It was seven letters, and it was there all along.
