Afternoon ReadA Rounded Teaspoon of Magnesium That the Listing Calls Two Grams and the Panel Calls 144 Milligrams: The Two Trials of That Form, Both Paid For by the Ingredient's Maker, the Cup of Coffee's Worth of Caffeine Stirred In With It, and Why a Jar Marked "30 Servings" Holds 24
Neuro Magnesi-Om is a seventy-four-dollar amber jar of powder from Moon Juice of Los Angeles, sold to be stirred into water or milk in place of the afternoon coffee, with a form of magnesium the listing calls two grams, a spoon of matcha or a squeeze of lemon, a little lion's mane, and fifty milligrams of caffeine. I read the panel against the listing, read the two trials of that magnesium and who paid for them, counted the caffeine, counted the teaspoons in the jar, read the thirty-seven reviews and the discount most of them earned, and read a return window that starts on the day the box arrives.
This is a paid advertisement. Sponsored by Moon Juice Inc.
Philip Renner is the pen name of this desk.
The customers quoted on this page are real; their reviews are public on the seller's product page and were read there on September 11, 2026, and four of the five were written by customers who received a discount from the store for writing, which is marked beside each.
I haven't met them and know nothing about them beyond what they wrote.
The small photos beside their reviews are illustrations, not the reviewers.
Everything about the jar, from the five lines on the panel to the forty-five-day return window, comes from the seller's own label and pages, read the same day.
Around two in the afternoon the day gets longer, and most men I know answer it with a second coffee.
This month I was asked to look at a jar that's sold to take the second coffee's place.
It's a small amber jar from a Los Angeles company, with the word Neuro on the front and the words "Focus, Memory" under it, and the listing leads with a number: two grams of a special magnesium in every rounded teaspoon.
I turned the jar over, and the panel says 144 milligrams.
Two grams on the listing. 144 milligrams on the panel.
Both numbers are true, and the difference between them is the first thing this page is about.
The second thing is who paid for the two trials of that magnesium, and the third is that the jar has caffeine in it, which the listing says plainly and the name doesn't.
One rounded teaspoon in six ounces of water or milk, in the morning or early afternoon, by the label. Every figure on this page is for that teaspoon.
Here's what the jar is.
Neuro Magnesi-Om, from Moon Juice, a Los Angeles company with a street address in its privacy policy, an email that answers, and no telephone anywhere on its site.
An amber glass jar in two flavors: matcha, which is 84 grams of pale green powder, and lemon, which is 90 grams of pale yellow.
A rounded teaspoon is the serving, 3.5 grams for the matcha and 3 for the lemon.
The panel, in the seller's order: ten calories, two grams of carbohydrate, and then the five lines that matter.
Magnesium, 144 milligrams, from 2,000 milligrams of a compound called magnesium L-threonate; a gram of matcha in the green jar only; 200 milligrams of a lion's mane extract; 100 milligrams of L-theanine; and 50 milligrams of caffeine from coffee beans.
I did what I always do on this porch.
I read the panel before I read the listing.
I read the two human trials of that form of magnesium, at the doses they used and in the people they used, and I read the last page of each to see who paid.
I read the government's own fact sheet on magnesium for what a man my age needs and what's too much from a jar.
I counted the caffeine and the teaspoons.
And I read the return page, which is fairer than most, and the shipping page, which for once includes a single jar.
What I found is a real mineral at a real dose printed two different ways, two trials that the ingredient's own maker paid for, one in people whose memory had already slipped and one in adults far younger than me, a cup of coffee's worth of caffeine sold as a coffee replacement, a jar that holds twenty-four teaspoons where the buy button says thirty, and a return window that starts when the box arrives.
One more thing before one o'clock, because most of you got here from one of our own advertisements.
Those ads talk about a boxed cereal, three foods, three drinks, and three words or phrases a man is supposed to be able to say.
None of that is in the jar, and I won't pretend it is.
It's on this page, in its place: the cereal, the drinks and the word test are the six o'clock section, and the honest version of every headline we run is in the guide linked at the foot.
One o'clock · The jarAn Amber Jar in Two Flavors, a Rounded Teaspoon, and Five Lines on the Panel
This is what's on the table.
A squat amber glass jar with a black screw lid and a cream label: Neuro, then Magnesi-Om, then "matcha magnesium L-threonate + lion's mane," then "Focus, Memory" with the asterisk every supplement carries.
The lemon jar says the same with lemon in place of matcha and adds the word caffeine on the front, which the matcha jar doesn't, though both have it.
The back is the panel, and I'll read it to you in the seller's order, per rounded teaspoon:
Calories, 10.
Total carbohydrate, 2 grams.
Magnesium, as Magtein magnesium L-threonate, 2,000 milligrams, providing 144 milligrams of magnesium, 34 percent of the Daily Value.
Organic ceremonial matcha powder, 1 gram, in the green jar only.
Organic lion's mane mushroom extract, 200 milligrams.
L-theanine, 100 milligrams; caffeine, from organic coffee bean extract, 50 milligrams.
Other ingredients: calcium silicate in the matcha; citric acid, lemon flavor, calcium silicate, monk fruit extract and turmeric for color in the lemon.
The directions: blend one rounded teaspoon in six ounces of hot or cold water or milk, up to twice a day, in the morning or early afternoon, and not so late that it keeps you up.
Five lines, one of them printed two ways, and a spoon of green tea in the green jar that brings its own caffeine without a number.
The magnesium gets the next section, because it's the reason for the jar.
Two o'clock · The two gramsWhy the Listing Says 2 Grams and the Panel Says 144 Milligrams, and What a Man My Age Actually Needs
Both numbers are on the seller's own pages, and both are honest once you know what each one counts.
Magnesium L-threonate is magnesium bound to a sugar acid, and the whole compound weighs about fourteen times what the magnesium inside it weighs.
So 2,000 milligrams of the compound is 144 milligrams of the mineral, and the mineral is the part your body counts.
The listing leads with the two grams, in large type, because two grams sounds like a lot.
The panel prints the 144 milligrams, in the line the law requires, and 144 milligrams is a third of a day.
Fourteen parts carrier, one part mineral.
What does a man my age need?
The government's fact sheet on magnesium sets the daily allowance for men over 31 at 420 milligrams, and says older adults eat less of it, absorb less of it from the gut, and lose more of it through the kidneys than younger people do. [1]
It also sets a ceiling for magnesium from jars and tablets, as opposed to food, at 350 milligrams a day, because above that the common forms tend to send a man to the bathroom faster than he'd like. [1]
One rounded teaspoon here is 144 milligrams, and the label's "up to twice a day" is 288, both under that ceiling.
So the mineral is real, the dose is honest, and the arithmetic favors the jar as far as magnesium goes.
What the arithmetic doesn't say is whether this particular form does anything for memory that a cheaper form wouldn't, and that's the next section.
Two grams of compound, 144 milligrams of magnesium, a third of a man's daily allowance in a rounded teaspoon and under the ceiling for magnesium from a jar. The listing's number and the panel's number are the same magnesium, counted two ways.
Three o'clock · The two trialsForty-Four People With Memory Trouble, a Hundred and Nine Adults Under Sixty-Five, and the Company Name on Both Last Pages
The form of magnesium in this jar has two trials in people, and I read both to the last page, because the last page is where the money is.
The first is a twelve-week trial in 44 adults aged 50 to 70 whose thinking had already slipped enough to be measured, half on 1.5 to 2 grams a day of the compound and half on a placebo, and the magnesium group scored higher on a combined measure of four kinds of thinking. [2]
Forty-four people is a small room, the people in it weren't healthy older men, and the study was paid for by the company that makes the ingredient, whose founder is the first name on the paper. [2]
The second is a thirty-day study in 109 healthy Chinese adults aged 18 to 65, who took two grams a day of the compound in a formula that also carried phosphatidylserine and three vitamins, and who scored higher than the placebo group on a hospital memory test. [3]
That study was paid for by the ingredient's maker too, the product came from the maker, the formula wasn't magnesium alone, and the oldest person in it was younger than I am. [3]
So the honest sentence is this: the form has two trials, both small, both short, both funded by the people who sell it, one in people who already had trouble and one in people mostly half my age.
Neither is a trial of healthy men over 55, and neither is a trial of this jar.
Two trials, one maker, no independent room.
I want to be fair about what that does and doesn't mean.
A company paying for the first studies of its own ingredient is how most of this business starts, and a paid study can still be an honest one.
It means the people with the most to gain designed the tests, and nobody without a stake has repeated them yet.
The listing's badge that promises clinical-grade potency is leaning on those two papers, and now you've read what they hold.
Two maker-funded trials, 44 people with memory trouble for twelve weeks and 109 mostly younger adults for thirty days, neither repeated by anyone independent and neither in men my age. The mineral is real; the memory claim rests on that, and only that.
Four o'clock · The cupFifty Milligrams of Caffeine, a Gram of Tea With Its Own, a Little Theanine, and a Small Dose of a Mushroom
Now the part of the jar you'll feel first, and the reason the seller says to take it early.
Every rounded teaspoon carries 50 milligrams of caffeine from coffee bean extract, which is about half a cup of drip coffee.
The green jar adds a gram of matcha, which is ground green tea leaf, and green tea leaf has its own caffeine; the label doesn't say how much, and a customer asked on the seller's page and got no answer.
So the green jar is somewhere north of 50 milligrams a teaspoon and the lemon jar is 50 even, and "up to twice a day" is at least 100.
The European food-safety authority puts single doses up to 200 milligrams and days up to 400 outside any concern for healthy adults, and says caffeine in moderate doses raises alertness and attention. [4]
That's the honest size of what you'll notice in the first hour: caffeine does that, from a jar or from a cup.
The seller's own page says so, and it also says not to stir this into coffee, because then you've doubled it.
Beside the caffeine sits 100 milligrams of L-theanine, an amino acid from tea leaves, and this pairing has one small trial worth knowing.
Twenty-seven volunteers took 50 milligrams of caffeine with 100 milligrams of theanine, exactly this jar's two numbers, and an hour later switched between tasks faster and more accurately, and were less thrown by distractions, than on placebo. [5]
One dose, twenty-seven people, a study whose authors worked for a tea company, and an effect that lasted the afternoon.
Theanine on its own has a single-dose study in Japanese adults aged 50 to 69 that reported faster reactions on an attention task. [6]
A pairing with a real, small, single-dose result on attention, at exactly the two numbers on this panel.
That's the best-matched line in the jar, and it's a line about the next ninety minutes, not about memory.
Last, the mushroom: 200 milligrams of a lion's mane extract, standardized to beta-glucans.
The one placebo-controlled trial of lion's mane in adults over 50 gave 3.2 grams a day of the mushroom for twelve weeks, sixteen times this line, and the scores fell back when they stopped. [7]
An extract is more concentrated than the whole mushroom, and the panel doesn't print by how much, so I can't close that gap for you.
Two hundred milligrams is a garnish beside the trial's dose, and the seller's page calls it "brain care" anyway.
Half a cup of coffee's caffeine plus a tea's worth you can't count, theanine at the dose of one small attention study, and a sixteenth of the lion's mane trial. The part you'll feel is the caffeine, and the seller's own directions say as much.
Five o'clock · The reviewsThirty-Seven Reviews, a Discount for Writing Them, and the Two Who Measured the Jar
The seller's page shows thirty-seven reviews with an average of 4.7 stars, and thirty-one of them were written for a discount.
The store offers ten percent off for a review and fifteen for one with a photo, and the review system marks the ones that took it.
That isn't a scandal; the store discloses the program, and I've marked the four rewarded reviews I quote as paid beside their names, because a discount is a payment.
I kept five, on purpose: two five-star, two three-star, and the one-star, because a page that shows you the top of the pile is selling, not reading.
I threw out the ones that talk about worry, calmness, the night, a condition, a medicine they'd rather not take, or a memory that came back, because our rules don't allow that language and because none of it can be checked.
These are real customers, quoted word for word from the seller's product page; the small photos beside them are illustrations, not the reviewers.
This matcha tastes really good and I love that I am getting magnesium with this while I drink it. The taste is not too strong, either.
My husband and I drink this daily before work. I just add it to my matcha I'm already drinking
I wasn't happy with my experience with this product. I was jittery with its use. I wanted it to work as an afternoon pick me up. I reduced the amount but still was jittery.
Good flavour, nice and light. I was really surprised when the jar arrived and it was only 1/3 full. I suppose it makes sense since there are only about 19 tsp in here (19.2 servings). So far no noticeable benefits but it's only day 3.
Not worth the price.
Read those the way I did.
Christen and Lindsay like the taste and the habit, and Lindsay stirs it into a matcha she was already drinking, which is a second gram of tea and a second dose of its caffeine on top of the jar's.
Kim wanted an afternoon lift and got the jitters instead, even at a smaller spoon, which is what 50 milligrams of caffeine plus a tea's worth does to some people.
Stephanie measured her jar and got nineteen teaspoons where the buy button promised thirty; the panel says twenty-four for the green jar, and a rounded spoon is a rough unit.
Karamie is four words long and disagrees with everyone about the price.
Nobody I kept describes a trial result, and nobody could, because no trial has ever tested this jar.
Two who like the taste, one who got the jitters, one who counted the spoons, and one who counted the dollars: that's the honest shape of the reviews, and the caffeine study is a better reason to try the jar than any of them.
Six o'clock · The bowl and the cupThe Cereal, the Three Drinks, the Three Foods and the Word Test From Our Own Advertisements
Our advertisements have been saying, in one version or another, that a boxed cereal, three foods and three drinks have something to do with memory, and that there are three words or phrases a man ought to be able to say.
You're owed the honest version, in one section, so here it is.
Start with the bowl.
A frosted, honey-coated or chocolate cereal is mostly refined starch and added sugar, and a serving can carry more sugar than a cookie.
No cereal "ages the brain faster than time."
Nobody has measured any such thing, and that phrase was written to be clicked.
What the studies do say is duller, and worth more.
In the Framingham Heart Study, adults who drank more sugary beverages scored lower on tests of memory, and daily fruit juice went the same way. [8]
In a Brazilian study of 10,775 adults followed for eight years, the ones who ate the most ultra-processed food, and the sweet cereal shelf is part of that, lost ground on tests of thinking about a quarter faster than the ones who ate the least. [9]
Both are associations across a population, not a sentence on your bowl.
And a quarter faster than slow is still slow.
The same Framingham families, in a different analysis, scored better on memory tests when their diets carried more choline, [10] which is eggs, milk, meat and beans, and none of which is in a rounded teaspoon of powder.
The three drinks.
The "evening drink" in our advertisement is alcohol, and it's the one with the strongest case behind it: in 550 British civil servants followed for thirty years, the more a person drank, the faster their scores fell on a word-fluency test, and light drinkers had no edge over those who didn't drink at all. [11]
The second is sugar in a glass: soda, sweetened tea, the tall flavored coffee from the counter, which is a soft drink with coffee in it.
The Framingham finding above is about sugary drinks, and those are sugary drinks. [8]
The third, in one of our headlines, was coffee.
That was our worst headline.
Plain black coffee and plain tea aren't the drinks any of those studies were about.
Keep your coffee.
And here's the odd part about this jar: it's sold to replace your afternoon coffee, and what it replaces it with is a smaller cup of caffeine with a mineral stirred in; if the caffeine is what you wanted, the coffee already had it.
The three foods.
Processed meat, fried food, and the white-flour shelf: pastries, packaged cakes, white bread.
Our advertisement says "just stop eating these three."
The research says something slower.
In 960 older adults followed for nearly five years, the ones whose meals looked most like the MIND pattern, vegetables, berries, nuts, whole grains, beans, fish and olive oil, held their thinking scores better, and the gap between the top and bottom thirds worked out to about seven and a half years of age. [12]
That's a pattern over years, not a list of three, and it can't be sold in a headline.
Which is exactly why our headline doesn't say it.
Notice that the greens, beans, nuts and whole grains on that shelf are where most of a man's magnesium comes from, at no charge and with no jar.
Less sugar in the bowl and the glass.
Less alcohol in the evening.
Keep the coffee.
Eat more like the Mediterranean shelf and less like the vending machine.
Every one of those costs nothing, and none of them is in the jar.
The three words, or the three phrases.
There's no such list.
What our advertisement borrowed from is the short, scored mental-status test clinicians have given at the bedside since the 1970s: the date and the place, a few words to hold in mind and give back a minute later, a sum, naming, repeating one sentence, copying a drawing.
It's given in person and read against your age and your schooling by someone trained to do it, and a low score is a reason for a proper look, not a verdict.
Stumbling on a word when you're tired or being timed means nothing on its own.
Nothing begins at a word.
If the worry behind the click is real, that's fifteen minutes with your own clinician, and it costs you nothing from me.
And the advertisement about the things some men take every day.
That one sits closest to real research, and it's the one an advertisement has no business acting on.
Some kinds of daily medicine, including a few sold over the counter for allergies and for the night, are on the lists pharmacists check for people over 65.
Don't stop or change any of it because of an advertisement, ours included. Put everything you take in one bag, this jar included, take it to the pharmacist, and ask one question: is anything here a poor choice at my age?
Two lines in this jar are worth naming at that counter: the magnesium, if your kidneys are being watched, because the fact sheet says older kidneys handle it differently, [1] and the caffeine, if anyone is watching your heart rhythm.
The guide at the foot of this page has that section written out, with the studies.
So if you clicked on the cereal, here's where the cereal went: onto the table next to a jar that shares one thing with your afternoon coffee, the caffeine, where the real answer was always a plainer bowl, a plate of greens and beans, and the coffee you already had.
Seven o'clock · What it isn'tSix Things a Rounded Teaspoon of This Powder Won't Do
- It won't give you two grams of magnesium. It gives you 144 milligrams; the two grams is the compound the mineral rides in on.
- It won't give you a trial in healthy men your age. The two trials are 44 people with memory trouble and 109 adults under 65, both paid for by the ingredient's maker.
- It won't replace your coffee without caffeine. It has 50 milligrams from coffee beans, and the green jar adds a tea's worth on top.
- It won't fill the jar to the brim. The matcha jar holds 24 rounded teaspoons where the buy button says 30, and one customer counted 19.
- It won't act on any condition a clinician has named. It's a dietary supplement, and its own label carries the sentence that says so.
- It won't come with thirty-seven independent opinions. Thirty-one were written for a discount, and the store says so in the system.
If that list annoys you, I'd rather you were annoyed now than on day twenty, when the jar is empty, the plan has charged you again, and you're jittery at three in the afternoon.
Eight o'clock · The routineIf You Do Buy It: One Jar, One Rounded Teaspoon at Two, Not in the Coffee, the Receipt Kept, One Notebook
If you're going to spend the money, spend it as a test with a date on it.
- Buy one jar, not the subscription, and buy the lemon if you already drink tea. Twenty-four days is the test in the green jar, thirty in the yellow, and the return clock is forty-five days from the day it arrives.
- Keep the confirmation email in a folder. Returns go through the seller's online returns page, and it wants the order number.
- Stir one rounded teaspoon into a glass of water at the same hour each early afternoon, in place of the second coffee, never in it. The seller's own page says stirring it into coffee doubles the caffeine.
- Don't take the second teaspoon the label allows until you've run a week on one. Kim got the jitters on a smaller spoon than the label's.
- Ask the pharmacist about the magnesium if your kidneys are being watched, and about the caffeine if anyone is watching your heart rhythm. Two minutes at the counter.
- Write one line a day in a notebook. Not "sharper" or "foggier." What you were doing at four, and how it went.
- On the last teaspoon, read the lines. If the afternoons read better than the month before, you've found a habit, and you should ask whether a plain glass of water and a smaller coffee would have done it; buy a second jar, not a plan. If they don't, you've found out for seventy-four dollars, and the return page tells you what happens next.
Look at that list the way I do.
Five of the seven things cost nothing.
The jar is the one you'll pay for, and the notebook is the one that will tell you the truth.
This is worth a look if:
- You want an afternoon cup with less caffeine than a coffee and a third of a day's magnesium in it, and you've read that the caffeine is the part you'll feel.
- You're short of magnesium in your diet, or a blood test says so, and you'd rather drink it than swallow a tablet.
- You can hold two ideas at once: a real mineral at an honest dose, and a memory claim that rests on two maker-funded trials in other people.
- You'll run one jar as a test with a notebook, and keep the email for the forty-five-day return window.
- You've asked the pharmacist about the magnesium and the caffeine, or you take nothing daily.
Give it a miss if:
- You wanted something without caffeine for the afternoon. This has half a coffee's worth, and the green jar has more.
- You wanted a trial in healthy men your age. There isn't one.
- You get the jitters easily. One customer did, on less than a teaspoon.
- You want something that acts on a condition a clinician has named. This is a dietary supplement.
- You'd like to phone the company. There's no number on its site; there's an email and a street address.
Nine o'clock · Where it's soldFrom a Los Angeles Company With a Street Address and No Telephone, Shipping Included on One Jar, and Forty-Five Days From the Day It Arrives
The jar is sold by Moon Juice on its own website, and that's the only place this page links to.
The company is findable and mostly reachable.
Moon Juice, with a street address in its privacy policy, an email that handles orders, returns and questions, and shops of its own in Los Angeles.
There's no telephone number anywhere on the site, and I looked at every page that might carry one.
If you're a man who likes to call before he buys, that's a fact about this company to weigh, and it's on this page because the seller's isn't.
The current price is shown on its page, not here.
The day I read it, one jar cost seventy-four dollars in either flavor, which is about three dollars a teaspoon in the green jar and two and a half in the yellow, and the page opens with the cheaper monthly plan already selected, so look at the buttons before you click.
Buy one jar.
Twenty-four days is a test.
A monthly plan for something you haven't tried is a bet, and the green jar doesn't reach the end of a month at one teaspoon a day.
Now the two things that matter more than the price.
First, shipping.
The seller ships at no charge on orders over sixty-five dollars in the contiguous states, and a single jar clears that line, which is the one place this jar is kinder than its cheaper cousins.
Second, the return window.
Read this twice, because it's better than most and has one thing it doesn't say.
The policy says the seller accepts returns within forty-five days of delivery, through an online returns page, and processes the refund within two or three business days of getting the jar back; for a damaged jar it asks for an email with a photo within seven days.
What it doesn't say is whether an opened jar counts or who pays the postage back, so ask by email before you post it, and keep the reply.
Count the mineral, then count the caffeine.
Forty-five days from the day the box arrives, an order number, an online returns page, and one email to ask about the opened jar: that's the whole promise, and it's a fair one for a jar that's finished on day twenty-four.
Keep the email, and buy the jar the window covers.
Every line on the panel is written out in the ingredient and advertising guide linked at the foot of this page: what each of the five is, what the research does and doesn't show and at what dose and who paid for it, what to name at the pharmacy counter, and which of our own headlines the jar does and doesn't support.
Print it and take it with you if you take anything daily; it's written for that.
QuestionsWhat Readers Ask Me Before Their First Jar
Questions readers ask
Is this medicine?
No. It's a dietary supplement, a form of magnesium with tea, a mushroom extract, theanine and caffeine in a jar, sold by a Los Angeles company.
The label carries the standard sentence every American supplement carries, the one that says the FDA hasn't evaluated its claims.
Does it have caffeine?
Yes. Fifty milligrams a teaspoon from coffee bean extract, about half a cup of drip coffee, and the matcha jar adds the caffeine of a gram of green tea on top, in an amount the label doesn't state.
The seller says to take it in the morning or early afternoon, and not to stir it into coffee.
How much magnesium is in a teaspoon?
144 milligrams of magnesium, which is 34 percent of the Daily Value, carried in 2,000 milligrams of magnesium L-threonate. The listing's "2g" is the compound; the panel's 144 is the mineral.
The daily allowance for a man over 31 is 420 milligrams, and the ceiling for magnesium from a jar is 350; two teaspoons is 288.
What do the trials of this magnesium show?
Two trials, both paid for by the ingredient's maker: 44 adults aged 50 to 70 whose thinking had already slipped scored higher on a combined test after twelve weeks, and 109 healthy adults aged 18 to 65 scored higher on a memory test after thirty days of a formula that also had other ingredients in it.
Neither was in healthy men over 55, and nobody independent has repeated them.
Will it help my memory?
I can't tell you that, and you should be wary of any page that does. What I can tell you is that the mineral is real and honestly dosed, that the memory claim rests on two small maker-funded trials in other people, and that nobody has tested this jar itself.
What you'll feel in the first hour is the caffeine, and the seller's own directions say as much.
Why does the buy button say 30 servings when the jar says 24?
The lemon jar holds 30 rounded teaspoons and the matcha jar 24, and the buy button prints 30 for both. The seller's own answer on its page confirms 24 for the matcha.
A rounded teaspoon is a rough unit; one customer counted 19.
Can I take it alongside what I already take?
Ask your clinician or pharmacist and take the ingredient guide with you. The magnesium is worth naming if your kidneys are being watched, and the caffeine if anyone is watching your heart rhythm.
Two minutes at the pharmacy counter answers it.
Are the reviews real?
They're public on the seller's page and most carry its buyer mark. Thirty-one of the thirty-seven were written by customers who received a discount from the store for writing, which the system discloses and which I've marked beside the four I quote.
Does it ship to me?
Within the United States and to Canada. Shipping is at no charge on orders over sixty-five dollars in the contiguous states, and a single jar qualifies.
What if it arrives and I don't like it?
Within forty-five days of delivery, start a return on the seller's online returns page with your order number, or email the company with a photo within seven days if the jar arrived damaged. The policy doesn't say whether an opened jar qualifies or who pays the return postage, so ask by email first.
Once the jar is back, the seller says the refund is processed in two or three business days.
Your advertisement was about a cereal, or three foods, or three drinks. Where is that on this page?
In the six o'clock section, in full, with the studies. The short version: less sugar in the bowl and the glass, less alcohol in the evening, keep your plain coffee, and eat more like the Mediterranean shelf, where most of a man's magnesium comes from anyway.
None of it is in the jar, and the ingredient and advertising guide at the foot goes through every headline we run and says which ones overstate.
Your advertisement said something about three phrases, or spelling three words. Is there a test I can take?
Not on a screen. The words and phrases come from the short mental-status test clinicians give in person, and it's read against your age and schooling by someone trained to do it.
Nothing begins at a word. If the worry behind the click is real, ask your clinician for the proper test.
It's fifteen minutes.

- An amber jar of powder from Moon Juice of Los Angeles, in matcha or lemon: 144 milligrams of magnesium from 2,000 of magnesium L-threonate, a gram of matcha in the green jar, 200 milligrams of lion's mane extract, 100 of theanine and 50 of caffeine per rounded teaspoon; 24 teaspoons in the green jar and 30 in the yellow; no telephone on the seller's site.
- The magnesium: a third of a man's daily allowance and under the ceiling for magnesium from a jar; [1] two trials of this form, 44 people with memory trouble [2] and 109 mostly younger adults, [3] both paid for by the ingredient's maker and neither repeated independently.
- The caffeine and theanine: exactly the two numbers of one small single-dose attention study; [5] the lion's mane: a sixteenth of its twelve-week trial's dose. [7]
- Thirty-seven reviews, thirty-one written for a discount; five quoted, four marked as paid, one who got the jitters and one who counted nineteen teaspoons.
- Shipping included on one jar; returns within 45 days of delivery through an online page, with one question about opened jars to ask by email first.
- The cereal, three drinks, three foods and the word test from our own advertisements, in the six o'clock section: less sugar, less alcohol, keep the coffee, more like the Mediterranean shelf, and no test on a screen. None of it is in the jar but the caffeine.
- The honest use: one jar, one rounded teaspoon in water at two in the afternoon and never in the coffee, a week on one spoon before the second, the pharmacist's two minutes, the email in a folder, and a notebook.
The last lineWhat Two Numbers Are Actually Worth
Here's the whole thing in one breath.
A real mineral at an honest dose, printed as two grams on the listing and 144 milligrams on the panel, both true.
Two trials of that form, small, short, paid for by the people who sell it, and run in people who aren't me.
A cup of coffee's worth of caffeine sold as a coffee replacement, a jar that holds twenty-four spoons where the button says thirty, a review page mostly written for a discount, and a company you can email but not call.
And a return window of forty-five days that starts when the box arrives.
If you're a man who wants a smaller afternoon cup with a third of a day's magnesium in it, who has read that the caffeine is what he'll feel and the memory claim is what he'll be sold, and who'll run one jar with a notebook and the email in a folder, that's worth one jar.
Not because of the reviews.
Because you'll know exactly what the two numbers are worth, and exactly which one the listing wanted you to see.
Buy one jar, stir one rounded teaspoon into water at two in the afternoon and never into the coffee, run a week on one spoon before the second, ask the pharmacist about the magnesium and the caffeine, keep the email, and write one line a day. The notebook is a better judge than I am, and neither of the trials was run on anyone like you.

P.S. If you take one thing from this page, take the two numbers.
Two thousand milligrams of compound, 144 of magnesium.
The listing prints the first in large type, and the panel prints the second where the law says it must.
P.P.S. If the afternoon fog has been with you for a year, and it's there before the coffee too, talk to your own clinician before you buy anything.
A teaspoon in a glass of water at two is a small habit.
It was never going to answer a question a clinician answers in fifteen minutes and a blood test, and a blood test is also the only way to know whether you were short of magnesium in the first place.
P.P.P.S. And if you do order it, keep the notebook, and keep the email.
When the jar is empty, you'll have twenty-four lines about your own afternoons and three weeks left on the return window, and both are worth more than the jar, whichever way the lines turn out.
