About 4Well
The 4Well Story
We started on the other side of the shelf.
4Well is a US supplement company, and for most of its life it wasn't a website at all — it was a seller on Amazon and Walmart. That is an unglamorous origin and also the most useful one: from the seller's side, every trick in this category is visible in daylight.
What we do with that is narrow and deliberate. Eight formulas, every active printed with its own number, no proprietary blends anywhere in the range, made and tested in the United States. We are trying to prove one thing — that a company can disclose everything without charging a hundred dollars a bottle for the privilege.
Full disclosure is the premium standard. We just don't think it should carry a premium price.

Where we came from
We didn't start with a lab. We started with a marketplace listing.
Years on a marketplace teach you the category from the wrong end of it. You learn which claims sell, which numbers can be printed without technically lying, and how much of a formula can disappear inside a single line on a label.
Here's how a bottle gets to look impressive: pick eight fashionable actives, put them in a proprietary blend so nobody can see there's 15 mg of each, print a bold number on the front that refers to the blend total, and let the reviews do the rest. It works. It's legal. It's most of the shelf.
What a marketplace listing doesn't give you is any way to prove you're not running that playbook. There's no room for a testing page, no room for a full ingredient rationale, no room to publish a certificate of analysis. That gap is the reason this site exists, and the reason every dose is now printed.
Where we're going
What we're trying to build
Three things we want to be true about 4Well that aren't fully true yet. They are written down here so they can be held against us later.
Disclosure without the premium
Every brand that prints its doses in full charges a premium for doing it. We want full disclosure to be the normal, boring, twenty-dollar option — and to still be at that price when the rest of the category catches up.
A formula built for a person, not for a shelf
Right now one pair of our products is split by biology. We want that to be the rule across the whole range: where two people need different actives at different doses, they get two formulas — not one bottle with two labels.
Proof you never have to ask for
Today the certificate of analysis for your batch arrives when you email us. The goal is a site where every lot number, every test result and every study behind a dose is already published, and nothing about a 4Well product depends on trusting us.
What we're reacting to
Four ways a supplement label misleads you
None of these are illegal. All of them are standard. Once you can name them you'll spot them on any shelf, ours included — which is the point.
Opaque blend
500 mg — one number for eight actives
4Well standard
300 mg KSM-66® · 200 mg theanine
Proprietary blends
Eight actives listed by name, one combined milligram total underneath. You cannot tell whether you're getting a studied dose of anything, and that's the function, not a side effect.
On the label
In the research
Fairy dusting
An ingredient included at a fraction of the researched amount, purely so it can appear on the label. The name does the marketing; the dose does nothing.
Magnesium oxide
Glycinate + citrate
Cheapest available form
Magnesium oxide instead of glycinate. Pyridoxine HCl instead of P-5-P. The label says “magnesium” and “vitamin B6” either way, and absorption differs by multiples.
Front claim
crude blend weight
Actual active
50% standardized
Front-of-bottle numbers
A large figure on the front that refers to the whole blend rather than to the active you came for. Technically accurate, practically meaningless.
Our rules
Five rules. Four of them the best brands already follow.
We stopped writing values because a value can't be falsified. These can. If you find a 4Well label that breaks one of them, tell us and we'll either fix the formula or drop the rule.
-
Separate formulas where the biology differs
Key standardOur men's and women's saw palmetto are different products, not different labels — different actives at different doses, because prostate support and hormonal support aren't the same problem. This is the rule most of the industry skips, including brands charging three times our price.
Men's biology
Saw Palmetto for Men
Saw palmetto with DHEA, arjuna and ashwagandha. Built around prostate and urinary support.
See the formula →Women's biology
Saw Palmetto for Women
Saw palmetto with DHEA and collagen peptides. Built around hormonal balance, skin and nails.
See the formula →One formula can't be right for a man and a woman. These are the two we make instead.
-
If the research used a dose, we use that dose
Or we leave the ingredient out. 300 mg of KSM-66® because that's the amount in the trials, not 50 mg so the word “ashwagandha” can appear on the front.
-
The form is named, not just the mineral
Glycinate, citrate, P-5-P, HCl, liposomal. “Magnesium 610 mg” tells you almost nothing on its own; the form is where absorption lives.
-
Where a branded extract has the research, we buy the branded extract
Generic root powder is a different material at a different concentration, so the published trials don't transfer to it. Paying more for the studied version is the only way the citation means anything.
-
Every active gets its own number
No proprietary blends, in any product, including the eight-ingredient ones where hiding doses is standard practice. We'd call this our defining rule, except the best brands in the category follow it too — so instead we'll say it's the one we're least willing to trade away for margin.
How a formula gets made
Six steps, in this order
-
Start from human trials
Not from what's trending on TikTok this quarter. If the evidence base is animal studies and enthusiasm, we don't build it.
-
Set the dose to match the trial
The studied amount, not the amount that keeps cost-per-bottle attractive. This is where most of the price difference comes from.
-
Choose the form for absorption first
Then look at price. Chelated over oxide, active B6 over the cheap salt, even when it costs several times more per kilo.
-
Write the label before formulating
Key stepThis is the rule the others follow from. If a dose would be embarrassing to print in full, the formula doesn't ship — we change it or we drop it. It's much harder to fairy-dust something when the label already exists.
-
Manufacture in a cGMP facility in the US
Blending, encapsulation and bottling under US standards, whatever country the raw material came from.
-
Test the finished capsule, batch by batch
Independent lab, testing identity, potency, heavy metals and microbiology on the finished product — not just on incoming ingredients.

Everything on this site is written and kept current by the people who work on the formulas. We don't have a clinician reviewing it, and we won't put “medically reviewed” on a page that hasn't been — which is why nothing here is written as medical advice.
The other half of the rules
Things we won't do
No proprietary blends
Not in any product, not ever, including the complicated ones.
No fairy-dusted ingredients
If it's below a meaningful dose, it comes off the formula rather than onto the label.
No claims that a formula treats or prevents anything
It isn't legal and it isn't true.
No countdown timers or fake stock counters
You'd spot it, and you'd be right to.
No “clinically proven formula”
We don't run our own trials. The honest phrasing is that our ingredients have been studied at these doses — and that's what we write.
No promising you'll feel it in three days
Sleep moves in about two weeks, hormones take three months. Saying otherwise sells one bottle and loses the customer.
No pretending a capsule outranks the basics
Nothing we make will outrun four hours of sleep a night, and we'd rather say so than sell you a second bottle.
No selling you a stack when one bottle would do
If you want a single active, a mono-product is cheaper and we'll tell you that.
Still open
What we're still working on
Publishing this list is a commitment, not a disclaimer. None of it is live yet; ask us where any of it stands.
Certificates of analysis published by lot number
Right now we email the COA for your batch on request. It should be searchable on the site instead — you shouldn't have to ask us for proof.
Third-party certification beyond our own testing
Independent batch testing is not the same as an NSF or USP certification mark. We're pursuing one.
A full ingredient library with linked studies
Every active, its form, its dose, why that dose, and the human trials it comes from — including the ones with mixed results.
A phone number
Email gets answered in a business day, but some questions want a voice. Fair criticism, and it's on the list.
