Supplement dosage checker
A supplement label is a marketing document. A long ingredient list reads as value, but the only thing deciding whether an ingredient does anything is the amount printed beside it — and on a great many labels that amount is a small fraction of the dose the published research used. The trade has a name for it: fairy dusting, an ingredient added in a quantity too small to matter, so that it can appear on the list.
Across the 244 products checked so far, 527 ingredients are printed on the labels. 116 of them are below half their published reference dose and 7 don't state an amount at all. 56 products have nothing on the label at a full dose.
This page does the arithmetic: the amount on the pack, multiplied by the servings a day, against a published reference dose. It compares figures — it does not rule on whether a product works. The best value picks below are the ones that come out of it actually delivering a full dose, at the lowest cost per full dose in their category.
Not medical advice
Best value picks
One per category: of the products that reach a full dose of the category's headline substance at their own stated serving, the cheapest per full dose. A low price for half a dose is not a low price, which is why the ranking is on cost per full dose rather than on the price on the shelf.
Affiliate links: "View on Amazon" links are affiliate links. We may earn a commission if you buy through one, at no cost to you. It does not affect which product is picked — the pick is arithmetic, and the same rule runs over every product in the category whether it is on Amazon or not.

Magnesium
Magnesium supplements compared against the EU Nutrient Reference Value of 375 mg of elemental magnesium a day. Magnesium is sold as a compound, and pack strengths almost always quote the compound weight rather than the mineral it contains — the elemental fraction ranges from about 60% for magnesium oxide down to roughly 7% for magnesium L-threonate, so a 2,100 mg pack can deliver less magnesium than a 500 mg one.
One caveat this comparison cannot resolve: ranking on dose alone favours magnesium oxide, which is high in elemental magnesium but the least well absorbed of the common forms. Several products here reach 100% of the reference value using oxide or hydroxide, and some blends marketed on their glycinate content are quietly buffered with oxide. Where a label discloses the split we record it; most do not.

Vitamin B12
Vitamin B12 supplements compared against the EU Nutrient Reference Value of 2.5 micrograms a day. No tolerable upper limit is established for B12, so no product here is flagged for exceeding one.
The caveat this category needs stating up front is the opposite of the magnesium one: dose is not the interesting axis. Nineteen of the twenty products carry between 400 and 200,000 times the reference value, so a dose comparison bands almost the whole category identically and tells a shopper nothing. What actually separates these products is the form (methylcobalamin against the cheaper synthetic cyanocobalamin), the delivery format, and how honestly the pack states its own numbers — a gummy and a tablet from the same brand carry the same 1,000 µg at a sevenfold difference in price per day, and the price spread across identical 1,000 µg methylcobalamin products runs from under 2p a day to 50p.

Collagen
Collagen supplements compared against 10 g of hydrolysed collagen a day — the dose used in the joint and skin trials the marketing on these packs rests on. There is no Nutrient Reference Value for collagen, so unlike the vitamin categories this figure comes from clinical use rather than regulation.
This is the category where dose separates products most sharply, and it separates them by format. Every powder and liquid here reaches at least half the reference dose and most reach all of it. Every capsule, tablet and gummy falls between 1.5% and 24% of it — not because they are cheaper, but because 10 g of powder is two tablespoons and will not fit in a capsule. A gummy at 150 mg a serving would need roughly 133 gummies a day to match one scoop of powder.
Compare on cost per gram of collagen, never on pack price or cost per serving. The headline price is close to meaningless here: the most expensive pack in this comparison is mid-table per gram, while some of the cheapest packs are the dearest per gram by a factor of forty. Watch, too, for pack fronts quoting a figure that is the sum of every active in the formula rather than the collagen alone, and for multi-source blends advertising five collagen types where four of them are present in single-milligram amounts.

Vitamin B7
Biotin supplements compared against the EU Nutrient Reference Value of 50 micrograms a day. No tolerable upper limit is established for biotin, so no product here is flagged for exceeding one.
As with vitamin B12, dose is not the axis that separates these products. Every one of them carries between 20 and 400 times the reference value, so a dose comparison bands the whole category identically. What separates them is price per day — a thirty-fold spread for the same molecule — whether the pack states its figure per tablet or per two-tablet serving, and whether the added zinc and selenium are present at a meaningful fraction of their own reference values or not at all.
One label here quotes its percentage against the US Daily Value of 30 µg rather than the EU value of 50 µg, printing 33,333% for a dose another pack prints as 20,000%. The two products contain exactly the same amount. Compare the microgram figures, never the percentages.

Vitamin B9
Folate supplements compared against the EU Nutrient Reference Value of 200 micrograms a day. Unlike the other B vitamins in this comparison, folate has a real tolerable upper intake level — 1,000 µg a day, and it is set for synthetic folic acid specifically. Several products here sit exactly on it.
Three different molecules are sold as ‘vitamin B9’ on these labels: synthetic folic acid, L-methylfolate (5-MTHF) and folinic acid. They are not interchangeable on a label, and at least one product in this comparison is titled ‘folic acid’ while containing none.
⚠️ Watch the units. Some packs state the amount in DFE (Dietary Folate Equivalents), a US-only unit that multiplies supplemental folic acid by 1.7 — so one tablet can be described as 1,667 µg DFE, 1,000 µg folic acid and 417% all at once, and only the middle figure compares with a UK label. Two products here print a percentage computed against the US Daily Value while labelling the column %NRV. Compare the microgram figure for the named form, never the percentage.

Creatine
Creatine supplements compared against 3 g of creatine a day — the intake the EU authorised performance claim is written for, and the figure most of these packs quote at themselves. No tolerable upper intake level is established, so no product here is flagged for exceeding one.
The catch in this category is a single word. Almost every pack is sold on a creatine monohydrate figure, and monohydrate is only about 88% creatine — the rest is the water it crystallises with. So a tablet advertising ‘3000mg’ of monohydrate delivers roughly 2.6 g of creatine and misses the 3 g claim it is being sold on, while another advertising the same 3000mg states it as Providing Active Creatine 3000mg from 3,372 mg of monohydrate and clears it. Only four labels in this comparison publish both numbers; for the rest the creatine figure is calculated from the compound weight, not printed on the pack.
Two other things to watch. A scoop size is not a dose: one flavoured powder here states 5 g per serving on the front and 4,250 mg of creatine monohydrate on the back, the difference being flavouring, sweetener, acid and colour. And format costs more than formula does — the powders in this comparison run from about 5p to 22p a day for the same molecule, single-dose sachets reach £1.00, and gummies 57p. There is no dose advantage on offer at the top of that range.

Iron
Iron supplements compared against the EU Nutrient Reference Value of 14 mg a day. Unlike most categories here, dose is not simply better when higher: the UK Expert Group on Vitamins and Minerals sets a guidance level of 17 mg a day from supplements, and products in this comparison run from 5 mg to 42 mg.
The good news for anyone reading a label is that iron is the one mineral the rules already handle well. EU labelling requires the elemental iron to be declared, so a pack saying “Iron 14 mg (from 42 mg of ferrous fumarate)” is telling you the dose first and the salt second — the opposite of magnesium, where the compound weight is usually the headline. The salts still differ enormously in how much iron they carry (ferrous fumarate and sulfate about 33%, bisglycinate about 20%, gluconate about 12%), but that arithmetic has been done for you.
What to compare instead is the number against the guidance level, and the cost of getting there. Several products here are marketed on carrying two or three times the reference value, and one pack presents its 28 mg against a rival’s 14 mg as a straight win. Iron is also the category where the safety wording matters most: accidental overdose of iron-containing products is a leading cause of fatal poisoning in young children, every UK pack carries a version of that warning, and anyone with haemochromatosis, or any man or post-menopausal woman without a diagnosed deficiency, should be taking advice rather than picking on price.

Absorbed best on an empty stomach, but that is also when it is most likely to upset the stomach — the packs here split evenly between the two instructions. Vitamin C taken alongside increases absorption; tea, coffee, milk and calcium reduce it.

Commonly taken in the evening. A large single dose can have a laxative effect; splitting it across the day reduces that.
The 250 mg upper level is EFSA’s figure for magnesium added to supplements, and it is set on the basis of loose stools rather than long-term harm — it is a tolerance threshold, not a toxicity one. Dietary magnesium from food is not counted towards it. Many products here exceed it while also meeting the 375 mg reference value, because the two figures answer different questions.
