What are the best multivitamin supplements for men in the UK?

The NRV column read top to bottom: the four shapes every nutrient in a multivitamin takes, and why the two minerals a lifter most wants are always token or absent

What are the best multivitamin supplements for men in the UK is a question that the front of the tub answers with the word men and a list of twenty-six nutrients, and that the back of the tub answers with a column almost nobody reads, the percentage of nutrient reference value beside each amount, which is where the whole product actually lives. Read top to bottom, every nutrient in that column takes one of four shapes, and counting the shapes is the review. The first shape is the full dose: a nutrient at or near a hundred per cent of its reference value, which is what a buyer imagines the whole tablet is and which, in most multis, describes the cheap water-soluble vitamins, C, the B vitamins, biotin and folate, plus vitamin D in the better ones, because a full dose of those is a few milligrams or micrograms and fits. The second shape is the token: a nutrient at five to fifteen per cent of its reference value, present at a dose that does nothing nutritionally and is there so that the nutrient's name can appear on the front of the tub and in the count of twenty-six; a multi listing magnesium at 50mg, 13 per cent, or calcium at 100mg, 12 per cent, has decorated its label with two minerals it has not supplied. The third shape is the overdose: a nutrient at several hundred per cent of its reference value, which for most water-soluble vitamins is harmless and excreted and is printed because large numbers sell, and which for one vitamin is worth watching, since B6 at the several-times-reference doses some men's and sports formulas carry has, over months of daily use above the safe upper level, a documented record of peripheral neuropathy, numbness and tingling in the feet and hands that resolves slowly after stopping. The fourth shape is the absent: the nutrients a tablet cannot physically carry at a useful dose, and the two that are always absent or token are the two a lifter most wants, magnesium and calcium, because a full dose of either is several hundred milligrams of compound, which with twenty other nutrients would make a tablet the size of a thumb that nobody would swallow. A multi that says magnesium on the front has told the buyer the name and not the dose, and a buyer reading the column sees it at once.

Counting the shapes sorts the shelf without reading a single front. A good multi, in the only sense the word has, carries the water-soluble vitamins and vitamin D at full dose, carries nothing at an overdose that matters, keeps B6 near its reference value rather than at several times it, and either leaves magnesium and calcium out honestly or states them at the token level they are, so that a buyer knows to buy them as themselves. A poor multi carries a long list of tokens for the front, an overdose or two for the numbers, and B6 at a level that the upper-level work says to avoid over the long term, and the column shows all three in a minute. The column also shows the one thing a varied diet leaves a lifter short of in winter, vitamin D, which a multi carries at full dose or not, and the one thing the national diet survey finds young men short of year round, magnesium, which no multi carries at all, which together are the reason a lifter on a varied diet needs the first as a multi or as itself and the second only as itself.

What the word men actually changes, iron and the token minerals, the multi a lifter on a varied diet does and does not need, the worked example as the nutrient a multi cannot carry, and the verdict

The word men on the front changes two things in the column and the marketing pretends it changes twenty. The first is iron, and it changes it by subtraction. A man's daily iron reference intake is 8.7mg, met from an ordinary diet containing meat, fortified cereal, pulses or greens, and supplemental iron is not recommended for men without a demonstrated deficiency, because iron that is not needed is stored rather than excreted and because a meaningful minority of people of northern European descent carry a gene variant for hereditary haemochromatosis, in which the body absorbs iron it cannot shed and routine supplemental iron accelerates the damage to liver, joints and heart that the condition does over decades; a men's formula should therefore leave iron out entirely, and a man's multi that carries iron at a hundred per cent, which many general formulas do, is the one case where the shape that looks best in the column is the wrong one. The second thing the word changes is the handful of minerals and plant compounds marketed to men, zinc, selenium and lycopene above all, which the column sorts as it sorts everything: zinc and selenium at or near a hundred per cent are real doses of minerals with authorised claims, including zinc's for normal testosterone levels in the blood and normal fertility, which is the claim the word men is borrowing, and at ten per cent they are tokens; lycopene has no reference value and no authorised claim and is in the formula for the front.

What a lifter on a varied diet does and does not need from a multi follows from the column. The water-soluble vitamins at full dose are, for a man eating meat, dairy, eggs, vegetables, fruit and grains, nutrients he already has, and the multi supplies them to someone who did not need them, which is harmless and is the reason the multi is the shelf's least necessary product; vitamin D at full dose is needed through the UK winter by everyone and is the one nutrient a multi carries that a varied diet does not, which is why a multi with 10 to 25 micrograms of vitamin D is, in winter, doing the one job a separate vitamin D would do; and magnesium, which the national diet survey finds a large share of young men below the reference intake for, is the nutrient a multi cannot carry and the one a lifter buys as itself. The worked example is that nutrient, bought as itself: {FL}, 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV in two capsules, a dose no tablet with twenty other nutrients could hold, carrying the authorised claims for normal muscle function, normal protein synthesis, normal nervous system function and the reduction of tiredness and fatigue, batch tested for lead, mercury, arsenic and cadmium, UK made under GMP and BRC, 180 capsules for £19.99 at 22p a day. The verdict on the best multivitamin supplements for men in the UK is that the best one is read from the column rather than the front: full-dose water-soluble vitamins and vitamin D, no iron, B6 near its reference value, zinc and selenium at real doses or honestly absent, and magnesium and calcium left out or stated as the tokens they are; and that a lifter on a varied diet needs, from the whole column, vitamin D in winter and magnesium as itself, which together cost less than most multis and supply what the multi either does in one line or cannot do at all.

What to check on the label

Questions people also ask

Which multivitamin is best for men in the UK?

The one whose nutrient reference value column, read top to bottom, has the right four shapes: the water-soluble vitamins and vitamin D at or near a hundred per cent, no nutrient at an overdose that matters and B6 near its reference value rather than several times it, no iron at all, since men meet their 8.7mg from food and a meaningful minority of northern Europeans carry a gene that makes supplemental iron harmful, zinc and selenium at real doses or honestly absent, and magnesium and calcium left out or stated as the tokens they are, since no tablet can carry a full dose of either; the word men on the front changes iron and little else.

Do men need a multivitamin?

A man eating meat, dairy, eggs, vegetables, fruit and grains already has the water-soluble vitamins a multi supplies at full dose, so the multi is giving them to someone who did not need them, harmlessly; what a varied diet leaves short is vitamin D through the UK winter, which a multi with 10 to 25 micrograms supplies in one line and a separate vitamin D supplies for pennies, and magnesium, which the national diet survey finds a large share of young men below the reference intake for and which no multi carries at a useful dose; those two, bought as themselves, cost less than most multis and do what the multi either does in one line or cannot do.

Should a men's multivitamin contain iron?

No; a man's daily iron reference intake is 8.7mg and is met from an ordinary diet, supplemental iron is not recommended for men without a demonstrated deficiency because unneeded iron is stored rather than excreted, and a meaningful minority of people of northern European descent carry a gene variant for hereditary haemochromatosis in which the body absorbs iron it cannot shed, so that routine supplemental iron accelerates the liver, joint and heart damage the condition does over decades; a men's formula should leave iron out, and a general multi carrying iron at a hundred per cent is the one case where the fullest-looking line in the column is the wrong one.

Why do multivitamins contain so little magnesium?

Physics: the magnesium reference value is 375mg of the element, which as oxide is over 600mg of compound and as citrate or glycinate well over a gram, and a tablet already carrying twenty other nutrients cannot hold it without becoming the size of a thumb, so multis carry 50 to 100mg, 13 to 27 per cent, which does nothing nutritionally and lets the name appear on the front; a lifter who wants magnesium buys it as itself at a stated elemental dose, around 300mg at 80% of the reference value, in a product that carries nothing else.

Can you take too much B6 from a multivitamin?

From a multi with B6 near its reference value, no; from the men's and sports formulas that carry B6 at several times the reference value, daily over months, the safe upper level work and the case literature describe peripheral neuropathy, numbness and tingling in the feet and hands that resolves slowly after stopping, which is why the column is read for B6 specifically and a formula with it at a few hundred per cent is passed over; symptoms of that kind in anyone taking a high-dose B6 product are a reason to stop it and see a doctor.
