Why are now supplements so cheap?

The price of a tub is six costs stacked, so here is the stack, and the five lines a large vertically integrated brand shrinks

Why are NOW supplements so cheap is a question about a large American family-owned brand that manufactures in its own facilities, runs its own laboratories, sells a very wide range at very high volume, spends almost nothing on advertising and packs in plain bottles, and the answer is found by taking apart the price of any tub into the six costs stacked inside it and asking which of the six such a brand has shrunk. Cost one is the raw material: the magnesium salt, the creatine, the fish oil, bought by the kilogram from a chemical or ingredient supplier at a price that falls steeply with quantity, so that a brand buying by the tonne for hundreds of products pays a fraction per kilogram of what a small brand pays for a few drums, and the saving goes straight to the first line of the stack. Cost two is manufacturing: blending, encapsulating, bottling and labelling, which most brands buy from a contract manufacturer who adds a margin for doing it, and which a brand with its own factory does at cost, removing the margin and running the lines at a scale where the fixed costs of a facility are spread across millions of units a year. Cost three is testing: identity, purity, potency and the category's analytes, which cost a fixed fee per batch at an outside laboratory and which a brand with its own accredited laboratory runs at marginal cost across every batch it makes, so that the per-unit testing cost of a high-volume product is pence where a small brand's is pounds. Cost four is packaging: the tub, the label, the seal and the box, where a plain white bottle with a two-colour label costs a fraction of a heavy matte tub with an embossed label and a presentation box, and where a brand that has decided its customers buy the contents rather than the container has shrunk the line on purpose. Cost five is marketing: the advertising, the sponsorships, the influencers and the campaigns, which for an advertised brand can be the largest single line in the stack, and which a brand sold by the breadth of its catalogue, its decades on the shelf and word of mouth has reduced to nearly nothing.

Five lines shrunk, and the sixth, channel margin, is different rather than smaller: a brand reaching the UK largely through online marketplaces and importers rather than through high street shelves pays the marketplace's fees and the importer's margin instead of a retailer's markup, which for a commodity product usually comes out lower. The stack explains cheap without a shortcut, and it is worth seeing that the explanation is structural: a brand with its own factory, its own laboratory, tonne-scale purchasing, plain packaging and no advertising can sell the same molecule for half the price of a brand that buys from a contract manufacturer, tests at an outside laboratory, packs in a presentation tub and runs campaigns, and the molecule in both tubs can be identical. The buyer of the advertised tub is paying for lines five and four, which do not reach the capsule, and the buyer of the plain tub is not, which is the whole of the difference for a well-specified commodity product and is a reason to prefer the plain tub rather than to suspect it.

Three reservations the stack does not show: the importer's responsibility, the commodity forms in a wide range, and the reads that a low price is a reason to run rather than skip

Three reservations sit outside the stack, and a UK buyer needs all three. The first is the cost the stack hides, which is the importer's responsibility. A product manufactured outside the UK is placed on the UK market by an importer, and under the food information regulations the food business operator under whose name the product is marketed is responsible for the label, which for an imported food means the importer must ensure a compliant label in English with a UK or EU address, the mandatory food supplement particulars, and amounts declared against the UK nutrient reference values rather than the American daily values. An authorised importer adds that cost and that address; a grey import, a tub bought in bulk abroad and listed on a marketplace by an anonymous seller, skips both, arrives with a US-format panel in international units and percent daily values, and has nobody in the UK answerable for it. The brand's own price is the same in both cases, and the difference between a bargain and a risk is entirely in who placed the tub on the UK market, which the seller name and the label's address reveal and which the grey-import audit on the marketplace legitimacy page walks through. The second reservation is the range: a brand with hundreds of products has, among them, the commodity forms chosen for cost per milligram rather than for absorption, magnesium oxide rather than glycinate, cyanocobalamin, synthetic vitamin E, and the cheapest tub in the range is often cheap because of its form as well as its stack; the form is on the label and the reads catch it. The third reservation is the reads themselves: a low price is a reason to run them rather than a reason to skip them, since a brand that is cheap by structure can still ship a batch out of specification, and the batch certificate for the tub's lot number, which a brand with its own laboratory can produce more easily than most, is the document to ask for.

The worked example is a UK tub priced by the same stack, with the lines shown so that a buyer can see where 22p a day goes: {FL}, raw material bought as magnesium bisglycinate at a stated 20 per cent elemental; manufactured in the UK on a GMP and BRC audited site; batch tested for lead, mercury, arsenic and cadmium with the certificate on request; packed in a plain tub with a label that carries every mandatory particular and a UK address; sold without an advertising campaign; and reaching the buyer through a marketplace listing sold by the brand, so that the sixth line is the marketplace fee and the importer's cost does not exist because nothing was imported. 1500mg of the compound stated as 300mg elemental at 80% NRV, two capsules with the evening meal, four authorised claims and no others, 180 capsules for £19.99 at 22p a day, which is the commodity price for the elemental milligrams with lines four and five kept small on purpose. Why are NOW supplements so cheap is answered by the stack: a very large brand that owns its factory and laboratory, buys by the tonne, packs plainly and does not advertise has shrunk five of six costs, and a UK buyer who confirms that the sixth was paid by an authorised importer with an address on the label, reads the form on the label and asks for the batch certificate has bought the stack's benefit without its one hidden cost.

Questions people also ask

How are NOW supplements so cheap?

By the structure of the price stack rather than by a shortcut: a large American family-owned brand that manufactures in its own facilities removes the contract manufacturer's margin, runs its own laboratories so that testing costs pence per unit across millions of units, buys raw material by the tonne for hundreds of products at the lowest price per kilogram, packs in plain bottles, and spends almost nothing on advertising because it is sold by the breadth of its catalogue and decades on the shelf; five of the six costs in any tub are shrunk, and the molecule inside can be identical to an advertised tub at twice the price.

Are cheap supplements lower quality?

Not by price alone; the price of a tub is six costs stacked, and two of the six, packaging and marketing, never reach the capsule, so an advertised brand in a presentation tub can charge twice as much for an identical molecule, and a plain tub from a brand with its own factory and laboratory can be cheap and in specification; what a low price is a reason for is running the ordinary reads, the form on the label, since the cheapest products in a wide range are often oxide or cyanocobalamin chosen for cost per milligram, and the certificate of analysis for the tub's batch number, which decides whether the batch matches its label.

Is it safe to buy American supplements in the UK?

Safe when an authorised importer has placed the tub on the UK market, which the food information regulations require: the importer becomes the food business operator responsible for a compliant label in English with a UK or EU address, the mandatory food supplement particulars and amounts declared against UK nutrient reference values; a grey import, bought in bulk abroad and listed by an anonymous marketplace seller, arrives with a US-format panel in international units and percent daily values and no UK address, so nobody in the UK is answerable for it, and the brand's own price is identical in both cases, which makes the seller name and the label's address the whole difference.

Why does the same supplement cost twice as much from another brand?

Because the other brand is paying for lines in the stack that the cheap brand has shrunk: a contract manufacturer's margin instead of its own factory, an outside laboratory's per-batch fee instead of its own, a heavy tub and a presentation box instead of a plain bottle, and an advertising budget that for some brands is the largest single cost in the price, none of which changes the molecule in the capsule; the difference is worth paying only when the dearer tub shows something the cheaper one does not on the reads, a better form, a higher elemental dose, a batch certificate the cheap one will not send, or a UK address the import lacks.

Which cheap supplement forms should lifters avoid?

The forms chosen for cost per milligram rather than absorption or activity, which a very wide range always contains: magnesium oxide, which has lower fractional absorption than citrate or glycinate and is the usual form in the cheapest magnesium, synthetic DL-alpha-tocopherol vitamin E, which has about half the activity per milligram of the natural form, and any product whose compound weight is stated without an elemental figure; cyanocobalamin is cheap and corrects B12 deficiency as well as the dearer form, so cheap is not always the worse choice, and the form on the label decides product by product.
