A Gram of Lion's Mane a Day in Two Capsules, With the Beta-Glucan Figure Printed on the Label: What That Gram Is, Where It Grows, and How Far It Sits From the 3.2 Grams of the Twelve-Week Trial in Adults Over 50

Real Mushrooms' Organic Lion's Mane Extract Capsules are the plainest bottle in this category I've read: one mushroom, hot-water extracted from the fruiting body, 1,000 milligrams per two capsules, 300 milligrams of beta-glucans, and nothing else but the capsule. I went from the oak the mushroom grows on to the number on the panel to the trial that made it famous, read the eleven hundred reviews' most recent page, and read the seller's two return pages, which don't agree with each other.

Everett Lowe 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 9, 2026.

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.

A customer of another product in the same store says the seller offered a ten-dollar credit for a review, so read every review on this page with that in mind.

Everything about the bottle, from the label to the two return pages, comes from the seller's own label and pages, read the same day.

The mushroom on this label grows on trees I've walked past my whole life.

Lion's mane comes off the trunks of old beeches and oaks in the woods of the northern half of the world, a white shaggy thing the size of a grapefruit with spines that hang down like a beard.

People have eaten it for centuries.

In Japan it's yamabushitake, the mountain-priest mushroom.

On the East Coast you can find it in October if you know which trees to look at.

So the honest first question about a bottle of it isn't whether the mushroom is real.

It is.

The question is how much of the mushroom is in two capsules, and how that amount compares with the only twelve-week trial in people my age.

That's what this page is.

The tree, the extract, the number on the label, the trial, the customers, and at the end, a return policy that turned out to be two.

One gram of extract a day, in two capsules.

Sixty days to the bottle.

Every number on this page is for that gram.

Here's what the bottle is.

Organic Lion's Mane Extract Capsules, from Real Mushrooms, a company with its office in Calgary, Alberta, that grows its mushrooms organically and ships its American orders from Sparks, Nevada.

A white bottle of 120 vegetable capsules, which at the label's two a day is sixty days; a 300-capsule bottle if you want five months.

The panel has one active line: organic lion's mane mushroom extract, 1,000 milligrams per two capsules, and under it, indented, the part most labels leave off: beta-(1,3)(1,6)-glucans, 300 milligrams.

Then the capsule itself: hypromellose, cellulose, silicon dioxide.

No caffeine, no vitamins, no second mushroom, no blend.

I did what I always do.

I read the label before the listing.

I read the trial behind the mushroom, at the dose it actually used, in people as old as I am.

I read the seller's page on how the extract is made, and its Canadian label, which says one thing the American one doesn't.

I read the ten most recent reviews of the eleven hundred and kept five.

And I read the seller's promise page and its return policy back to back, which I recommend, because they were written by two different people.

What I found is the most honest mushroom label I've read this year, one real ingredient at a real amount, printed with the number that tells you it's really there, and a gram a day that sits at a third of the trial dose, from a seller whose two return pages don't agree.

One more thing before the first line, 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 capsule, 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 seventh line, and the honest version of every headline we run is in the guide linked at the foot.

Line one · The treeA White Beard on an Old Oak, and the Part of It That Goes in the Bottle

This is where it starts.

A large white lion's mane mushroom with hanging spines growing from the trunk of an old oak in an autumn wood

Lion's mane, Hericium erinaceus, is a wood-rotting fungus.

It grows where an old hardwood has been wounded, a broken limb or a woodpecker hole, and it pushes out a white mass that ripens into a cascade of soft spines.

The part you see on the tree is the fruiting body.

The part you don't see, the threads inside the wood, is the mycelium.

That distinction matters more than anything else on a mushroom label, and I'll say why in a moment.

Cooked, it has a texture people compare with crab.

It's eaten as food in China, Japan and Korea, and it's been in American farmers' markets for twenty years now, grown on logs and on sawdust blocks.

A mushroom you can buy at a market and cook is a different kind of ingredient from most of what's sold for memory.

It's food first.

Line two · The extractHot Water, the Fruiting Body Only, and the Word "Mycelium" That Isn't on This Label

The line that separates this bottle from most of the ones beside it on the shelf.

Real Mushrooms says its extract is made by simmering the fruiting body, the part you'd eat, in hot water, and drying what comes out.

That's the traditional way, and it's the way the trial preparation was made too, more or less: dried fruiting body, ground.

The seller also says, on the label and everywhere else, that there's no grain, no starch and no mycelium in the bottle.

Here's why that word matters.

A lot of mushroom supplements are grown as mycelium on grain, and the grain gets ground up with the threads and goes in the capsule.

Those products are mostly starch, and the mushroom compounds are a small fraction.

The seller's Canadian label puts a number on its own extract: one-to-one, 500 milligrams of extract from 500 milligrams of dried mushroom, per capsule.

So a gram of this extract is about a gram of dried mushroom.

Not a concentrate, not a grain powder.

The mushroom, dried, in a capsule.

Hot-water extract of the fruiting body, one-to-one, no grain. That sentence is the whole difference between this bottle and a bottle of ground-up mycelium on rice, and it's printed.

Line three · The numberThree Hundred Milligrams of Beta-Glucans, and What a Printed Figure Is For

The indented line under the mushroom, and the reason I'd trust this label over one that doesn't have it.

Beta-glucans are long chains of glucose that make up much of the cell wall of a mushroom.

They're the fraction a serious mushroom-extract maker measures to show how much mushroom, rather than grain or filler, is in the product, and a hot-water extract concentrates them.

This label prints 300 milligrams per gram, which is 30 percent, and the seller's page says it promises more than that.

What the number isn't is a promise.

I registered no trial of beta-glucans on memory or attention in healthy adults.

The figure is a quality measure, the way the octane number on a pump tells you what's in the fuel and not how far you'll drive.

Thirty percent, printed, is the honest reason to prefer this bottle over a cheaper one.

It isn't a reason to expect anything the trial didn't find.

Three hundred milligrams of beta-glucans per gram tells you the mushroom is really there.

It doesn't tell you what it will do.

Most labels don't tell you either thing.

Line four · The trialOne Gram a Day Against Three Point Two

The line the whole bottle stands on, and the honest arithmetic behind it.

The trial worth reading is small and has been read many times.

Thirty-one Japanese adults over 50 took a daily preparation of the dried fruiting body, 3.2 grams a day, in tablets three times a day, or a placebo, for twelve weeks.

The lion's mane group scored higher on a standard mental-status test than the placebo group, and the difference faded in the weeks after they stopped. [1]

A visual-retention test in the same trial didn't change.

Three point two grams of dried mushroom a day.

Two capsules of this extract are a gram, and the seller's own label says that's about a gram of dried mushroom.

A third of the trial's daily amount.

Three bottles a day would get you there, and the bottle would last twenty days.

There's a second study, in younger people, that's honest to mention.

Forty-one healthy adults aged 18 to 45 took a single 1.8-gram dose or a placebo, and the lion's mane group was faster on an attention task an hour later; after 28 days at that dose there was a trend on one questionnaire and nothing clear on the other tests. [2]

A gram is a little over half of that single dose.

A gram a day is a real amount of the right part of the mushroom, honestly labeled, at a third of the only twelve-week dose in people over 50. That's the sentence to buy or not buy on.

And the caution that goes with it, from the trial and from the seller's own label.

A few participants in one clinical study reported stomach discomfort, nausea or a skin rash.

Anyone allergic to mushrooms should leave it alone.

The label says to check with a clinician before use if you take anything daily or have a medical condition, and I'd do exactly that.

Line five · The reviewsEleven Hundred Reviews, the Ten Most Recent, and Five Kept

The seller's product page shows more than eleven hundred reviews, and each of the ten most recent, which is what the page loaded for me, carries the store's own buyer mark.

The seller's page also notes that its average rating and count are aggregated from Amazon and its own store.

I read the ten and kept five, including one at four stars from a woman a week in.

I threw out one that spoke of a condition that isn't this page's business, one that was mostly about a different product, and two that didn't say anything.

And I'll tell you what I found on a different product's page in the same store: a customer who says the seller offered him a ten-dollar credit for a review.

I have no way of knowing which of the reviews below were nudged that way, so read all of them as if they might have been.

These are real customers, quoted word for word from the seller's product page; the small photos beside them are illustrations, not the reviewers.

telma m. Confirmed Buyer
★★★★★
I love, love, this product. It makes me feel energized, sharp and ready for life! I have let many People Know about it!

Read those the way I did.

Susan has taken it for five years and puts her difference at three months in, which is the one review on the page shaped like the trial: months, not mornings.

Marvin researched brands and chose this one.

That's a review of the label, and the label earns it.

Nina, at four stars, is a week in and says it's too early to tell, which is the most honest sentence a person can write a week in.

Telma feels energized and sharp.

There's no caffeine in the bottle and no trial that measured "energized," so I read that as a woman who's glad to have a routine.

Nobody I kept describes their memory coming back.

One describes three months, one describes a label, one describes a week, one describes a feeling.

That's what a gram a day looks like from the customer's side of the counter.

Line six · The two promisesA Hundred Days on One Page, Thirty and Unopened on the Other

This is the section I'd read twice if I were you, because it's the one where the seller's pages disagree.

A man's hands comparing two printed pages side by side beside a small white bottle

The product page and a page of its own, called the 100-Day Satisfaction Promise, say this: on every product the seller makes, if it isn't the right fit, the seller will help you find one that is, or make it right with a replacement or a full refund.

One opened product per customer.

Meant for reasonable evaluation.

Only for purchases on the seller's own site.

Contact by email, phone or text.

The seller's return policy, a different page, says this: unopened, unused products within 30 days of shipping can be returned with a prepaid label; from 31 to 60 days you pay the shipping; after 60 days, no returns; opened products are not accepted, "no exceptions."

The same page also mentions a 30-day satisfaction promise, with a refund of the product price or an exchange, for purchases on the seller's site.

So which is it?

I take the seller at its most recent and most specific word, which is the hundred-day page: one opened bottle, per customer, evaluated in good faith, refund or replacement.

But I'd write to the seller before I bought, ask which page governs, and keep the answer.

A promise that lives on one page and is contradicted on another is a promise you want in writing.

A hundred days for one opened bottle on the promise page; thirty days and unopened on the return page. Ask first, keep the email, and buy the 120-count bottle, not the 300.

Line seven · 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, on one line, so here it is.

A bowl of frosted cereal beside its box, a glass of water and a small white bottle on a wooden table

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. [3]

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. [4]

Both are associations across a population, not a sentence on your bowl.

And a quarter faster than slow is still slow.

A mushroom capsule with no sugar and no grain is the one thing on this page the cereal shelf and the supplement shelf don't share.

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. [5]

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. [3]

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.

These capsules have no caffeine, and taking them doesn't change how much you're drinking.

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. [6]

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.

Mushrooms are a vegetable on that list, and a pan of sautéed lion's mane from the market is a better supper than a capsule is a supplement.

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 capsule.

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 bottle included, take it to the pharmacist, and ask one question: is anything here a poor choice at my age?

The label itself tells you to ask if you take anything daily.

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 bottle that has nothing to do with it, where the real answer was always a plainer bowl and a pan of mushrooms for supper.

Line eight · What it isn'tSix Things Two Capsules Won't Do

  • It won't wake you up. There's no caffeine in it and nothing else but the mushroom.
  • It won't give you the lion's mane of the trial. A gram is a third of the 3.2 grams a day that produced the twelve-week result.
  • It won't be a concentrate. The seller's own label calls it one-to-one: a gram of extract is about a gram of dried mushroom, honestly, and no more.
  • 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 suit anyone allergic to mushrooms, and a few people in one study had an upset stomach or a rash.
  • It won't come with one return policy. It comes with two, and you should ask which one applies before you buy.

If that list annoys you, I'd rather you were annoyed now than when the bottle arrives from Nevada.

Line nine · The routineIf You Do Buy It: The 120-Count Bottle, Two Capsules at Breakfast, Sixty Days, One Notebook

If you're going to spend the money, spend it as a test with a date on it.

  • Buy the 120-count bottle, not the 300. Sixty days is the test, and the hundred-day promise, if it governs, covers one opened bottle per customer.
  • Email the seller first and ask which return page applies to an opened bottle. Keep the reply.
  • Two capsules with the same breakfast every day, for the whole sixty days. The trial took twelve weeks; a capsule on the days you remember won't test it.
  • Keep the coffee exactly as it was. There's nothing in the capsule to change your morning.
  • Write one line a day in a notebook. Not "sharper" or "foggier." What you were doing at ten, and how it went.
  • On day sixty, read the sixty lines. If they read better than the two months before, you've found a habit, and the 300-count bottle makes sense. If they don't, you've found out for the price of one bottle, and the promise page says you can ask for the money back.

Look at that list the way I do.

Four of the six things cost nothing.

The bottle is the one you'll pay for, and the notebook and the same breakfast at the same hour are the ones that will do the work.

A man's hands writing a line in a small notebook beside a glass of water and a small white bottle

Line ten · Who it's forWho It Suits, and Who It Doesn't

This is worth a look if:

  • You want lion's mane on its own, from the part of the mushroom you'd eat, with no second ingredient and no blend, and you've now read what a gram is against the trial.
  • You want a label that prints the beta-glucan figure and a seller that prints how the extract is made. You have both now.
  • You want a company with a street address, a toll-free number, an email and a warehouse in the United States. You have all four now.
  • You can hold two ideas at once: the most honest label on the shelf, at a third of the trial dose.
  • You'll email the seller about the promise first, and run the bottle as a sixty-day test with a notebook.

Give it a miss if:

  • You want the trial dose. Two capsules are a third of it; six a day is a bottle every twenty days.
  • You're allergic to mushrooms, or you take anything daily and haven't asked a pharmacist. The label tells you to ask; do that first.
  • You want something that acts on a condition a clinician has named. This is a dietary supplement.
  • You want a return policy that says one thing. This seller's pages say two, and the return page is the stricter one.
  • You'd rather eat the mushroom. So would I; a pan of it from the market is a supper, and the capsule is a habit.

Line eleven · Where it's soldFrom Calgary, Shipped From Nevada, With Shipping at no charge Above a Line

The bottle is sold by Real Mushrooms on its own website, and that's the only place this page links to.

A quiet Calgary street at dawn with bare poplars and faint snow-capped mountains at the end

The company is easy to find.

Real Mushrooms Inc., with its office on Fifth Avenue Southwest in Calgary printed on the label, a second Calgary address on its return page, a toll-free number that takes calls and texts, and an email.

American orders ship from a warehouse in Sparks, Nevada, which is also where returns go.

The label says the extract is verified for its active compounds and tested by an independent lab, and it prints the beta-glucan figure.

The current price is shown on its page, not here.

The day I read it, the 120-count bottle cost about what a good pair of work gloves costs, and it worked out to well under a dollar a day; the 300-count bottle was cheaper per capsule.

Buy the 120.

Sixty days is a test.

Five months of something you haven't finished is a bet, and the promise covers one opened bottle.

Now the two things that matter more than the price.

First, shipping.

Real Mushrooms ships within the United States from Nevada; shipping costs nothing above the seller's order line, and a single 120-count bottle, the day I read it, was below that line, so expect a small shipping charge.

Second, the return policy.

Read this twice, because there are two of them.

The promise page: a hundred days, one opened product per customer, replacement or refund, by email, phone or text, for purchases on the seller's site only.

The return page: unopened products only, prepaid label within 30 days of shipping, your postage from 31 to 60 days, nothing after 60, and opened products not accepted.

Both pages are the seller's own words.

Ask which one applies before you pay, and keep the answer.

I'd rather say so than call it a refund with no strings.

QuestionsWhat Readers Ask Me Before Their First Bottle

Questions readers ask

Is this medicine?

No. It's a dietary supplement, one mushroom extract in a vegetable capsule, made for a company in Calgary.

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?

No. Nothing in the bottle but the mushroom extract and the capsule.

What does "one-to-one" mean?

It's on the seller's Canadian label: 500 milligrams of extract from 500 milligrams of dried mushroom, per capsule. A gram of this extract is about a gram of dried lion's mane.

It isn't a concentrate, and it isn't ground-up mycelium on grain.

How does a gram compare with the trial?

The twelve-week trial in adults over 50 used 3.2 grams a day of the dried fruiting body. Two capsules are about a third of that.

Six capsules a day would match it, and the bottle would last twenty days.

What are beta-glucans, and does 300 milligrams do anything?

Long chains of glucose from the mushroom's cell wall, and the fraction a serious maker measures to show the mushroom is really there. The figure is a quality measure; I found no trial of beta-glucans on memory or attention in healthy adults.

Will it help my memory?

I can't tell you that, and you should be wary of any page that does. The only twelve-week result in people your age came at three times this daily amount.

What the customers I kept describe is three months, a label, a week, and a feeling.

Can I take it alongside what I already take?

Ask your clinician or pharmacist and take the ingredient guide with you. The label itself says to check with a clinician if you take anything daily, and anyone allergic to mushrooms should leave it alone.

Are the reviews real?

They're public on the seller's page and carry its buyer mark. A customer of another product in the same store says the seller offered a ten-dollar credit for a review, so I'd read all of them with that in mind.

I quote them word for word.

Does it ship to me?

Within the United States, from Nevada. At no charge above the seller's order line; a single 120-count bottle is below it, so expect a small charge.

What if it arrives and I don't like it?

The seller's promise page says a hundred days and one opened bottle per customer, by email, phone or text. Its return page says unopened bottles only, within 30 days for a prepaid label.

Write to the seller before you buy, ask which applies, and keep the reply.

Your advertisement was about a cereal, or three foods, or three drinks. Where is that on this page?

On line seven, 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, mushrooms included.

None of it is in the capsule, 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.

The short versionEverything Above, in Sixty Seconds

  • A bottle of 120 vegetable capsules from Real Mushrooms of Calgary, shipped from Nevada: organic lion's mane extract, hot-water extracted from the fruiting body, 1,000 milligrams per two capsules, 300 milligrams of beta-glucans printed, no grain, no caffeine, nothing else.
  • The seller's Canadian label calls the extract one-to-one: a gram of extract is about a gram of dried mushroom.
  • A gram a day is a third of the 3.2 grams of the twelve-week trial in adults over 50. [1] The single-dose study in younger adults used 1.8 grams. [2] Beta-glucans are a quality measure, not a promise.
  • Eleven hundred reviews with the seller's verified mark; the four I kept say "three months," "the best available," "too early to tell," and "energized," and a customer of another product in the store says the seller offered ten dollars for a review.
  • Ships from Nevada; at no charge above the seller's line; a hundred-day promise on one opened bottle on one page, and an unopened-only return rule on another: ask first.
  • The cereal, three drinks, three foods and the word test from our own advertisements, on line seven: less sugar, less alcohol, keep the coffee, more like the Mediterranean shelf, and no test on a screen. None of it is in the capsule.
  • The honest use: two capsules with the same breakfast for sixty days, a notebook, and an email to the seller before you pay.

The last lineWhat a Gram of the Mushroom Is Actually Worth

Here's the whole thing in one breath.

One mushroom that grows on the oaks in your own woods, dried and put in a capsule by a company that prints how it was made and how much is really there.

A gram a day, a third of the trial, from the right part of the mushroom, with no grain and no second line.

Eleven hundred customers, the most honest of whom is a week in and says so.

And two return pages, one generous and one strict, waiting for you to ask which is which.

If you're a man who wants lion's mane on its own, from a label he can trust, tested over sixty days with a notebook, that's worth one bottle.

Not because of anything on the front.

Because you'll know exactly what's in the two capsules, and exactly how far that is from the trial.

Buy the 120-count bottle, email the seller about the promise first, take two capsules with the same breakfast, and write one line a day for sixty days. The notebook is a better judge than I am.

Organic Lion's Mane Extract Capsules

A gram a day of hot-water lion's mane extract in two capsules, with the beta-glucan content printed on the label.

CHECK AVAILABILITY

Sold by Real Mushrooms Inc., Calgary, and shipped within the United States from Sparks, Nevada · Shipping at no charge above the seller's order line; a single bottle is below it · A 100-day satisfaction promise on one opened product per customer on the seller's promise page, and a stricter unopened-only return policy on its return page: ask the seller which applies before you buy

P.S. If you take one thing from this page, take the two numbers.

One gram a day, a third of the trial.

Three hundred milligrams of beta-glucans, printed, which is how you know the gram is really mushroom.

Everything else about this bottle sits between those two.

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.

Two capsules at breakfast are a small habit.

They were never going to answer a question a clinician answers in fifteen minutes and a blood test.

P.P.P.S. And if you do order it, keep the notebook, and keep the seller's email about the promise.

When the bottle is empty, you'll have sixty lines about your own mornings and one answer in writing, and both are worth more than the bottle, whichever way the lines turn out.
