A multivitamin has no single dose, so nothing is totalled or ranked by milligrams or ingredient count. Compare the audience, the serving schedule and each key nutrient as the label states it (iron, vitamin D, folate, B12, vitamin K, iodine). Amounts are label amounts per labelled daily serving, not adequacy ratings; where directions give a range, the range is shown. Read the dose guide ↓

How to read multivitamin doses nutrient by nutrient
UK multivitamin labels use nutrient-specific NRVs, not a single multivitamin target. [2] A product may provide 100{3683f0b818e4e7eac3a25ad8212965194ab09621a23bd0189e97e17dfedff11f} NRV for zinc while only 16{3683f0b818e4e7eac3a25ad8212965194ab09621a23bd0189e97e17dfedff11f} NRV for magnesium; adding those percentages together would be meaningless.
NRV is also not always the same as current UK intake guidance. For example, the vitamin D label NRV is 5 mcg, while NHS guidance says adults need 10 mcg/day and should consider a 10 mcg supplement during autumn and winter. [4] Iron requirements differ by sex and age, and pregnancy has separate folic-acid/vitamin-A guidance. [7][8]
For each product, calculate every nutrient separately from the labelled daily serving. Never create a total-active milligram figure.
What multivitamin evidence does — and does not — show
Multivitamins can help increase micronutrient intake when diet does not supply enough, but they can also push some nutrients too high when combined with fortified foods or separate supplements. [11]
Long-term randomized evidence does not show a broad cardiovascular benefit: the Physicians' Health Study II found no reduction in major cardiovascular events after a median 11.2 years. [12] The same trial found a small reduction in total cancer incidence, but not a broad reduction in site-specific cancers or cancer mortality. [13]
Newer COSMOS studies suggest modest cognitive benefit in older adults using a specific older-adult multivitamin, but this does not establish that every formula improves cognition. [14]

Read the full evidence-by-goal detail
Filling nutrient gaps
A multivitamin can raise intakes of nutrients that are low in the diet, but adequacy and excess must be assessed nutrient by nutrient. [11]
Heart and cancer prevention
Current trial evidence does not justify selling a general multivitamin as cardiovascular prevention. Cancer evidence includes a small signal in one major trial but is not a universal prevention result. [12][13]
Healthy ageing and cognition
COSMOS cognitive studies in older adults found modest benefits with a specific commercial multivitamin/mineral. [14] The evidence is audience- and product-specific.
When to take a multivitamin
There is no one evidence-based time of day for every multivitamin. Follow the product directions. Taking a multi with food can improve tolerance and may help absorption of fat-soluble vitamins, but medicine-specific timing instructions take priority.
If a multivitamin contains iron, calcium, magnesium or vitamin K, check medicines and other supplements rather than assuming all ingredients can be taken together.
Multivitamin safety, overlap and interactions
Who should be cautious?If any of the following apply to you, speak to a healthcare professional before taking Multivitamin - see the full detail below for why.
Pregnant people or those trying to conceive who need prenatal-specific guidance
People taking warfarin or another medicine with nutrient interactions
People already taking several standalone vitamin/mineral supplements
People with diagnosed iron deficiency, B12 deficiency or another condition requiring clinician-led dosing
People choosing high-potency formulas with several nutrients far above label NRVs
Multivitamin safety depends on the individual nutrients and total intake from food, fortified products and other supplements. UK legislation does not set one multivitamin maximum, and national statutory maximum levels for every vitamin/mineral supplement have not been established; nutrient-specific guidance must be used. [10]
Key examples include the NHS 10 mg/day supplemental vitamin B6 caution, iron overlap, preformed vitamin A/retinol in pregnancy, and vitamin K with warfarin. [6][7][8][9]
Multivitamins alongside other supplements
Before adding standalone vitamin D, iron, zinc, magnesium or other supplements, check what the multivitamin already supplies. Overlap can turn an ordinary individual product into a high total intake.
This is particularly important for vitamin A, vitamin B6, iron and other nutrients with specific safety guidance. [5][6][7]
Who might consider a multivitamin
Most people should aim to meet nutrient needs through a healthy balanced diet, while specific supplements are recommended in some situations such as vitamin D in autumn/winter and folic acid around pregnancy. [1][4][8]
A multivitamin can be a practical way to cover several small gaps, but the formula should match the person's life stage rather than simply contain the largest number of nutrients.
How to compare multivitamin testing evidence
Multivitamins are harder to verify than single-ingredient products because a strong test programme needs to confirm many nutrients, relevant chemical forms, contaminants and finished-product performance. A heavy-metals-only report does not confirm the vitamin/mineral label.
The Supplement Compare's testing guide distinguishes manufacturer claims, COAs, independent testing and recognised certification. Read the guide Testing quality should therefore depend on the report's scope, not simply the words 'third-party tested'.

Your questions, answered
Is 100{3683f0b818e4e7eac3a25ad8212965194ab09621a23bd0189e97e17dfedff11f} NRV of every vitamin and mineral ideal?
No. NRVs are label reference values, not a universal multivitamin recipe. Some bulky minerals are commonly partial, while nutrient needs and safety limits differ. [2] A product should be judged nutrient by nutrient.
Should men and women take different multivitamins?
The label should be assessed against actual nutrient needs rather than the gender marketing alone. Iron is one obvious difference: NHS requirements vary by sex and age. [7]
Can I take vitamin D as well as a multivitamin?
Check how much vitamin D the multivitamin already provides. NHS adult guidance is 10 mcg/day, with autumn/winter supplementation advised for everyone and year-round supplementation for some groups. [4] Avoid unintentionally stacking multiple products.
Can I use a normal multivitamin in pregnancy?
Pregnancy has specific guidance. NHS recommends folic acid and vitamin D and advises avoiding supplements containing preformed vitamin A/retinol. [8] A prenatal formula should therefore be assessed separately.
Do multivitamins prevent heart disease or help you live longer?
A major long-term randomized trial found no reduction in cardiovascular events, and a 2024 analysis of three large prospective cohorts found no mortality benefit. [12][15]
