Why One Supplement Costs Three Times Another

Two products sit side by side on the shelf. One costs eleven pounds, the other thirty-four. The ingredient list looks broadly similar and the milligram numbers are comparable. Almost everyone concludes the expensive one is a markup on identical material — and sometimes that's exactly right. But there are five specific places where the cost genuinely goes, and knowing them turns an impossible comparison into a fairly quick one.

01One: the form of the ingredient

This is the largest single driver and the easiest to check.

Magnesium oxide costs a fraction of magnesium bisglycinate. Folic acid costs a fraction of methylfolate. Zinc oxide costs a fraction of zinc picolinate. Iron sulphate costs a fraction of iron bisglycinate. In each pair, the cheaper option is also the one your body absorbs less of.

So a large share of the price gap between two magnesium products isn't margin — it's the difference between a bulk industrial salt and a chelate that costs several times more per kilogram to produce. The cheap product isn't a bargain version of the expensive one; it's a different material with a different absorption profile.

Check the word after the nutrient name. If two products name different forms, you're not comparing like with like and the price difference is partly explained before you look at anything else.

02Two: standardisation, for anything botanical

For plant extracts, the concentration step is where the money goes.

Ground root or raw powder is cheap. An extract standardised to a verified percentage of active compounds requires processing, testing and rejection of material that doesn't meet spec. Enriching for a minor constituent — AKBA in boswellia, for instance — is more expensive again.

A turmeric product at 1,000 mg of root powder and one at 500 mg of extract standardised to 95% curcuminoids can differ by an order of magnitude in actual compound delivered, and the price follows that rather than the milligrams.

03Three: delivery technology

Several compounds absorb poorly on their own — curcumin, berberine, quercetin, CoQ10 among them. Fixing that costs money.

Phytosome complexes, liposomal preparations, enzymatically modified forms and particle-size reduction all require additional manufacturing steps and often a licensed branded ingredient with a royalty attached. A product that has solved its absorption problem has spent real money doing it, which is why it says so on the front.

Conversely, a large milligram number with no delivery story attached is the cheap way to look potent.

04Four: testing

This one is invisible on the shelf and it's where a lot of the difference sits.

Independent third-party testing costs money per batch — identity, potency against label claim, heavy metals, microbials. A company testing every production lot carries that cost continuously. A company testing occasionally, or relying on a supplier's certificate, or not testing at all, does not.

The reason this matters is that testing is the only thing standing between a label claim and reality, and it's the easiest cost to remove without any visible change to the product. Two bottles can look identical and differ entirely in whether anyone independent has confirmed what's inside.

Which is why the practical question isn't "does this brand test" — nearly all of them say yes — but "can I read the certificate for the lot number on this bottle, right now, without asking."

05Five: what isn't in it

Capsule material, flow agents and excipients all have cheaper and more expensive versions, and none of it appears on the front of the label.

This is worth understanding without being oversold. These choices affect cost genuinely; they are not usually the main event, and a brand building its entire pitch on what it left out is often distracting from a weaker answer on forms or testing.

06Where the expensive product is genuinely not worth it

Being even-handed: sometimes the premium buys nothing.

Creatine monohydrate is the clearest case — the cheapest form is also the best-evidenced, and premium creatine forms mostly solve a problem the research hasn't found. Plain ascorbic acid is well absorbed and inexpensive; exotic vitamin C forms are usually a comfort feature rather than an efficacy one. And any product whose premium rests on an ingredient present at a token amount is charging for a name.

Price is not a proxy for quality. It's a signal that something cost more to make, and your job is to work out whether that something is the form, the standardisation, the delivery, the testing — or the marketing budget.

07The one-minute comparison

Put two bottles side by side. Compare the forms, not the milligrams. For botanicals, compare standardisation percentages. Check whether either addresses absorption. Check whether either publishes a certificate you can open right now. Then divide by servings rather than by bottle, since serving sizes differ more than people expect.

That's usually enough to explain most of a price gap, and occasionally enough to reveal that the cheaper product is the better buy.

08How we approach it

We name every form, state every amount, avoid proprietary blends and publish an independent certificate for every lot on the product page. Those choices are most of why our products cost what they do, and we'd rather explain that than let the number sit unexplained.

A supplement being expensive proves nothing on its own. A supplement being expensive for reasons you can identify on the label is a different proposition — and the five above are where the money actually goes.
