Why the Same Formula Has Several Names

Who actually makes a supplement

Every page, every journal post, the bottle facts and the ingredients go through review by Dr. Rachel Rubin, MD before they ship. Ask most people who makes the supplement in their cupboard and they will read the name on the front of the bottle. That name is usually a brand, and a brand is usually not a factory.

The industry is organised around contract manufacturers: companies that own the mixing equipment, the gummy depositors, the encapsulators and the quality systems, and that make products to order. A brand comes to them with a budget and a category — “a men’s vitality gummy” — and leaves with a finished product. Often the formula is one the manufacturer already had on a shelf.

That arrangement is called white-labelling, or private-labelling, and it is entirely legal. It is also how a very large share of the supplements sold online reach a customer. It is why a category can go from nothing to fifty brands in eighteen months: nobody had to develop fifty formulas.

What white-labelling is good at, and what it is not

It would be lazy to treat this as a scandal, because it is not one, and the honest version has two columns.

The second column is the reason this post exists. If you are choosing between two products, you are implicitly assuming they are different products. Sometimes they are not, and the assumption costs you the whole comparison.

How to spot it from the panel

A Supplement Facts panel is close to a fingerprint. Two brands can use the same ingredient list by coincidence — this category recycles the same dozen botanicals — but they do not match by coincidence on the details below.

That last row deserves emphasis, because it is the one that turns a suspicion into a conclusion. Two companies can independently choose the same nine herbs. Two companies do not independently make the same spelling mistake in the same sentence of the same warning paragraph.

Running the comparison on Jellyfil

We have read a different brand’s label — a different name, a different bottle design, a different website — and put it next to this one. Here is what matched.

Eight matches, including a typo and a distributor address. The bottles look nothing alike: one is navy and gold art deco, the other is not. The marketing is different, the ingredient graphics name a different subset of six, and the sales pages promise different things.

Underneath, on the only part of the package that is a regulated document, they are the same product.

Read the Jellyfil panel for yourself, line by line.

What it should change about how you buy

If two brands are the same product, then most of the ways people choose between supplements stop working. Here is what still works.

1. Compare panels, not pages

   Two sales pages can differ completely while the products are identical. Two panels cannot.

2. Compare price per day

   Total ÷ (bottles × days). If the product is the same, this is the whole comparison.

3. Compare refund terms

   Window length, who pays return postage, whether opened bottles qualify. These are set by the seller, not the manufacturer, so they genuinely differ.

4. Compare the phone number

   Call it before you buy. A desk that answers is a real difference between two identical products.

5. Ignore the branding

   The bottle design, the name, the hero image and the bonus stack are the part that was cheap to change.

There is a version of this that is good news. If you have found a formula you like and a cheaper brand sells the same panel, you can buy the cheaper one with confidence. The fingerprint works in both directions.

And the question the panel cannot answer

Matching panels tell you two products were formulated the same way. They do not tell you the two batches are the same, and that distinction matters.

Two brands ordering the same formula can still receive material from different ingredient suppliers, made at different times, tested to different specifications — or not tested at all. The panel describes the recipe. A certificate of analysis describes the batch.

Neither brand here publishes one, which is the ordinary state of affairs in this category and the single document most worth asking a seller for. And the reason to ask is not academic: the FDA maintains a public list of sexual-enhancement products found to contain undeclared prescription drug ingredients, and that is a batch-level problem rather than a formula-level one (U.S. Food and Drug Administration, “Tainted Sexual Enhancement Products”).

The bottom line

Most supplements are made by companies whose names are not on the bottle. A formula is developed once and sold to several brands, each of which supplies the design and the promises.

You can detect it from the panel: the blend weight, the order of the names, the footnote, the other-ingredients line, the distributor and — most reliably — the typos.

On this product, eight of those matched another brand’s label exactly. That is not a reason to avoid it. It is a reason to stop comparing websites and start comparing price, refund terms and whether somebody answers the phone (U.S. Food and Drug Administration, “Dietary Supplements: What You Need to Know”).
