Is NOW supplements a good brand?

One brand, two shelves: why a catalogue of hundreds carries both the commodity forms and the better ones, and why the brand is only as good as the tub a buyer picks from it

Is NOW supplements a good brand is a question about a large American family-owned manufacturer with a catalogue of several hundred products, and the honest answer begins with something that a catalogue that wide does which a small one cannot: it sells the same brand on two shelves at once. A brand with eight products chooses one form of magnesium and lives with the choice; a brand with hundreds carries magnesium oxide for the buyer who wants the biggest number for the least money, magnesium glycinate and citrate for the buyer who has read about absorption, and magnesium in several other salts besides, all under the same name and the same plain label, and the same is true of its B12, cyanocobalamin and methylcobalamin side by side, its vitamin E, the synthetic DL-alpha-tocopherol and the natural form, its calcium, the carbonate and the citrate, and its fish oils at two or three concentrations. The first shelf holds the commodity forms, chosen for cost per milligram and for a large label number, and a buyer who picks a tub from it has a value-playbook product with the absorption cost that playbook carries; the second shelf holds the better-absorbed forms, chosen for the buyer who reads the ingredients paragraph before the price, at a somewhat higher price that is still the commodity price for that form. The brand is good in the precise sense that it lets a buyer choose, which a narrower brand does not, and it is only as good as the tub the buyer chose, which is why two people can hold a tub each of the same brand and one has a well-absorbed mineral at a stated elemental dose and the other has an oxide whose large number delivers less. Neither tub is dishonest; the form is in the ingredients paragraph on both, and the catalogue's width is an invitation to read it.

So the question is a good brand splits into a question about the company, which the next section answers, and a question about the tub, which the buyer answers by reading the form and the elemental dose on whichever of the two shelves they have reached for, and the second question is the one that decides whether the purchase was good.

The company behind the brand, the testing scale an own laboratory gives, the UK ledger that the importer's address decides, the worked example with one shelf, and the verdict

The company behind the brand answers the question who makes it more plainly than most, and that is a real point in its favour. It is a privately held American manufacturer that makes its products in its own facilities rather than buying them from a contract manufacturer the label does not name, which means the maker and the brand are one company and the facility standard is the company's own; and it runs its own laboratories, which test every batch at the marginal cost that scale allows, so that a certificate of analysis for a lot number is produced more easily than most brands can manage and the mechanism behind batch-to-batch consistency, release testing against a written specification, is in the building. Those two facts place the company well on the quality questions that are about the building, identity, purity and consistency, and they say nothing about the form in any given tub, which is the catalogue's two-shelf question and the buyer's to answer. The UK ledger is the third question and the one the brand does not control. An American tub reaches a UK buyer either through an importer who, under the food information regulations, becomes the operator responsible for an English label with the mandatory particulars, amounts against the UK nutrient reference values and a UK or EU address, or through an anonymous marketplace account that bought a pallet abroad and skipped all of that; the tubs are identical, the company's reputation is identical, and the difference between a lawful product with a company to write to and a grey import with nobody in the UK answerable is entirely in the address on the tub and the name of the seller. A buyer holding a tub from this brand with an importer's UK address on an over-label has a good brand's tub on the UK market; a buyer holding the same tub with a US-only panel has a good brand's tub and no UK recourse.

The worked example is a brand with one shelf, so that the choice the wide catalogue leaves to the buyer is already made: {FL}, magnesium bisglycinate and no other form, 1500mg of the compound stated as 300mg elemental at 80% NRV, two capsules with the evening meal, UK made under GMP and BRC with the operator's UK address printed and nothing imported, batch tested for lead, mercury, arsenic and cadmium with the certificate for the lot number on request, four authorised claims and no others, 180 capsules for £19.99 at 22p a day, which is the second shelf's form at the second shelf's price with the UK ledger already in order. The verdict on is NOW supplements a good brand is that the question has three answers: the company is a good one in the sense that matters for the building, a manufacturer that makes its own products and tests every batch in its own laboratories; the brand is good in the sense that its catalogue carries both the commodity forms and the better ones and lets a buyer choose; and the tub is good only if the buyer chose from the right shelf, read the form and the elemental dose in the ingredients paragraph, and bought it through an importer whose UK address made it a product someone here is answerable for, which is a question the brand's reputation cannot answer and the label can.

Questions people also ask

Is NOW a good supplement brand?

In three senses that need separating: the company is a good one for the questions about the building, a privately held American manufacturer that makes its products in its own facilities and tests every batch in its own laboratories, which answers who makes it and how it is checked more plainly than most brands; the brand is good in that its catalogue of hundreds carries both the commodity forms, oxide and cyanocobalamin, and the better-absorbed forms, glycinate and methylcobalamin, under one name and lets a buyer choose; and a given tub is good only if the buyer chose from the right shelf and bought it through an importer whose UK address makes someone here answerable.

What company makes NOW supplements?

The brand belongs to a privately held, family-owned American manufacturer that makes its products in its own facilities and runs its own laboratories, so the maker and the brand are the same company and the facility standard is its own, which is more than most supplement brands can say, since most are marketing companies buying from a contract manufacturer the label does not name; for a UK buyer the more useful question is who imported the tub, since the company's own reputation does not travel across the border without an importer's address on the label.

Which NOW magnesium is best?

The one from the second shelf: the catalogue carries magnesium oxide, chosen for cost per milligram and a large label number with the lower fractional absorption that form has, and magnesium glycinate and citrate, chosen for the buyer who reads, with better absorption at a somewhat higher price that is still the commodity price for the form; the form is in the ingredients paragraph on both, the number to compare is the elemental milligrams rather than the compound weight, and a stated glycinate at around 300mg elemental is the benchmark the oxide is read against per absorbed milligram.

Why does the same brand sell both cheap and better forms?

Because a catalogue of several hundred products serves two buyers at once and a wide manufacturer can afford both shelves: the buyer who wants the biggest number for the least money gets the commodity form, oxide, cyanocobalamin, synthetic vitamin E or calcium carbonate, and the buyer who has read about absorption gets the glycinate, the methylcobalamin, the natural tocopherol or the citrate under the same name; neither tub is dishonest, since the form is printed in the ingredients paragraph of both, and the catalogue's width is an invitation to read it before reaching for the price.

Is it safe to buy NOW supplements in the UK?

Safe when an importer has placed the tub on the UK market and, under the food information regulations, taken responsibility for an English label with the mandatory particulars, amounts against the UK nutrient reference values and a UK or EU address, which appears on an over-label or a converted panel; the same tub bought from an anonymous marketplace account that shipped a pallet from abroad arrives with a US-only panel in international units and percent daily values and nobody in the UK answerable for it, and the brand's own reputation is identical in both cases, so the address and the seller's name are the whole difference.

The vitamin and mineral form literature: magnesium oxide has lower fractional absorption than citrate or glycinate; synthetic DL-alpha-tocopherol has about half the biological activity of the natural RRR form per milligram; cyanocobalamin and methylcobalamin both correct B12 deficiency; form changes absorption or activity per milligram rather than whether a nutrient works.

The batch release and certificate of analysis framework: a product has a written specification for identity, assay, contaminants and physical properties, each batch is tested against it before release, and the certificate of analysis for a batch reports the results against the specification, so that batch-to-batch consistency is read by comparing certificates across lot numbers.
