Women's Multivitamin UK: What to Look For (2026 Guide)

By the GUUDIES Editorial Team · Updated 25 October 2026 · Guidance checked against NHS pages and the GB Nutrition and Health Claims Register (sources below).

Disclosure: GUUDIES makes a daily gummy pouch with a multivitamin gummy in it. We set out below what it does and does not contain, so you can compare fairly.

The short answer: a good women's multivitamin covers vitamin D at 10µg or more, and then fits the nutrients your life stage needs. Women who could become pregnant need 400µg of folic acid, women with heavy periods may need iron, and anyone pregnant should avoid vitamin A (retinol). Gummies are easier to take every day but usually carry fewer nutrients, and less iron, than tablets, so read the label per daily serving.

Do Women Need a Multivitamin?

The NHS says most people should be able to get the vitamins and minerals they need from a varied and balanced diet. There are a few clear exceptions where UK guidance recommends a supplement or flags a common shortfall:

Vitamin D: everyone in the UK should consider 10µg a day in autumn and winter, and all year if they get little sun on their skin.
Folic acid: 400µg a day if you could get pregnant or are trying, until 12 weeks of pregnancy.
Iron: women aged 19 to 50 need 14.8mg a day, more than men, and the NHS notes heavy periods are a common reason for iron deficiency anaemia.
Vitamin B12: vegans and some vegetarians may need a supplement or fortified foods.
Iodine: adults need 140µg a day; people who eat little dairy or fish may fall short.

A multivitamin is a convenient way to cover several of these at once, which is why many women take one.

What to Look For in a Women's Multivitamin

Check	Why it matters
Vitamin D of at least 10µg	The amount the NHS recommends; vitamin D contributes to the maintenance of normal bones and normal immune function.
Folic acid 400µg if you could get pregnant	The NHS amount for the months before and early in pregnancy.
Iron, if your diet or periods call for it	Iron contributes to the reduction of tiredness and fatigue. Many gummies contain little or none.
B12 and B6	Both contribute to the reduction of tiredness and fatigue; B12 matters most if you eat few animal foods.
No vitamin A (retinol) if pregnant	The NHS advises avoiding retinol supplements in pregnancy unless your doctor says otherwise.
Individual amounts and %NRV	A long ingredient list means little without the amount of each nutrient per daily serving.
Base and sugar (for gummies)	Check whether it is gelatine or pectin based, and how much sugar is in a daily serving.

Women's Multivitamin Gummies vs Tablets

Gummies are easier to take, which helps people keep the habit, but space in a gummy is limited. That is why multivitamin gummies often leave out iron (which also tastes metallic) or carry smaller amounts of minerals such as calcium and magnesium. Tablets and capsules fit more. Neither format is better in itself: compare the amounts per daily serving, not the format.

By Life Stage

Trying for a baby or pregnant: choose a pregnancy supplement with 400µg folic acid and 10µg vitamin D and no vitamin A (retinol). A general women's multivitamin is often not suitable. Some women are advised to take a higher dose of folic acid, so ask your GP or midwife.

Heavy periods: if you feel tired, short of breath or notice heavy bleeding, see a GP rather than guessing with supplements, as a blood test can confirm whether you need iron and how much.

Perimenopause and over 50: after the menopause, iron needs fall to 8.7mg a day. Vitamin D, calcium from food and vitamin K all relate to the maintenance of normal bones.

Safety: Don't Double Up

If you take a multivitamin, check any other supplements you take for the same nutrients. The NHS sets limits for supplements, such as 1.5mg a day of vitamin A from food and supplements combined, 25mg of zinc and 17mg of iron unless a doctor advises more. If you take prescription medicine, ask a pharmacist before starting.

How GUUDIES Compares

The Daily Greens+ gummy in each GUUDIES pouch provides 14 vitamins and minerals per day, including vitamin D3 20µg, vitamin B12 24µg, vitamin B6 1.7mg, vitamin C 80mg (100% NRV), vitamin K2 80µg, iodine 38µg and zinc 2.75mg, plus a 200mg greens blend.

To be clear about what it is not: it contains no iron and no folic acid, and it does contain vitamin A as retinol (800µg). So it is not a pregnancy supplement, and it will not cover iron if you need it. It suits adults who want a broad daily routine in an easy format. The pouch has six pectin-based gummies; five are vegan, and the Marine Collagen gummy contains fish.

Common Questions

What is the best multivitamin for women in the UK?
The one that matches your needs: vitamin D for everyone, folic acid if you could become pregnant, iron if your diet or periods call for it, and B12 if you eat few animal foods. Compare amounts per daily serving.

Are women's multivitamin gummies effective?
They provide the nutrients on the label like any other format, but often in smaller amounts and usually without iron. Check the %NRV of the nutrients you care about.

Should I take a multivitamin every day?
If you take one, daily is how they are designed to be used. Do not take more than the stated serving.

Can I take a women's multivitamin while pregnant?
Only if it is made for pregnancy. Avoid vitamin A (retinol) and make sure you get 400µg of folic acid and 10µg of vitamin D. Ask your midwife or GP.
