What Vitamins Should Women Take Daily?

A Guide to Essential Vitamins & Supplements

With so many vitamins and supplements available, it can be difficult to know where to start.

Should women take a multivitamin every day? Do you need vitamin D? What about iron, magnesium, B12, folic acid or omega-3?

The answer depends on your age, diet, lifestyle and stage of life. A woman in her 20s who has regular periods may have very different nutritional requirements from someone going through menopause or a woman following a vegan diet.

At Your Local Pharmacy, we're here to make choosing supplements simpler.

In this guide, we look at some of the most important vitamins and minerals for women, what they do and when supplementation may be worth considering.

Quick Answer: What Vitamins Should a Woman Take Every Day?

There isn't one supplement routine that's right for every woman.

A healthy, balanced diet should provide most of the nutrients your body needs. However, some nutrients deserve particular attention, including:

• Vitamin D

• Folic acid

• Iron

• Vitamin B12

• Calcium

• Magnesium

• Omega-3 fatty acids

• B vitamins

• Vitamin C

• Zinc

Whether you actually need to supplement each one depends on your diet and individual circumstances.

For many women, the goal shouldn't be to take as many supplements as possible. It should be to identify what you actually need.

1. Vitamin D – An Important Everyday Consideration in Ireland

If there's one vitamin worth paying particular attention to in Ireland, it's vitamin D.

Vitamin D contributes to:

• Normal function of the immune system

• Maintenance of normal bones

• Maintenance of normal muscle function

• Normal absorption and utilisation of calcium and phosphorus

• Maintenance of normal teeth

Our bodies can produce vitamin D when skin is exposed to sunlight, but Ireland's climate means getting sufficient vitamin D from sunlight throughout the year can be challenging.

For healthy adults aged 12–65 in Ireland who get summer sunlight exposure and have fair skin, current Irish guidance recommends 15 micrograms (600 IU) of vitamin D daily during the extended winter months, from the end of October to March.

Some people are advised to supplement throughout the year, including adults with darker skin, pregnant women and adults aged 65+.

Who should pay particular attention to vitamin D?

Consider your vitamin D intake if you:

• Spend most of your day indoors

• Get little sun exposure

• Cover most of your skin outdoors

• Have darker skin

• Are pregnant

• Are over 65

• Have been advised by a healthcare professional that you're at risk of deficiency

Our tip: Check your multivitamin before buying separate vitamin D. It may already provide your daily amount.

2. Folic Acid – Particularly Important for Women Who Could Become Pregnant

Folic acid isn't only something to think about after discovering you're pregnant.

Women who could become pregnant are advised in Ireland to take 400 micrograms (mcg) of folic acid every day, even if they're not currently planning a pregnancy.

Folic acid is the supplemental form of folate, also known as vitamin B9.

Folate contributes to:

• Normal blood formation

• Normal psychological function

• Normal function of the immune system

• Reduction of tiredness and fatigue

• Maternal tissue growth during pregnancy

Adequate folic acid before and during early pregnancy is particularly important because it helps reduce the risk of neural tube defects.

If you could become pregnant, this is one supplement that's worth making part of your daily routine.

3. Iron – Especially Important for Women Who Have Periods

Iron deserves particular attention during the reproductive years.

Iron contributes to:

• Normal formation of red blood cells and haemoglobin

• Normal oxygen transport in the body

• Normal energy-yielding metabolism

• Reduction of tiredness and fatigue

• Normal cognitive function

• Normal function of the immune system

Women who have periods have greater iron requirements because iron is lost through menstrual blood.

Signs that can occur with iron deficiency include:

• Persistent tiredness

• Lack of energy

• Shortness of breath

• Heart palpitations

• Pale skin

• Headaches

However, these symptoms can have many different causes.

Should every woman take an iron supplement?

No.

Iron is a good example of a supplement that shouldn't automatically be added to everyone's daily routine.

If you have heavy periods, follow a restrictive diet or regularly experience unexplained fatigue, speak to your GP or pharmacist. A blood test can determine whether you have iron deficiency or iron-deficiency anaemia.

4. Vitamin B12 – For Energy Metabolism & Nervous-System Health

Vitamin B12 has several essential roles in the body.

It contributes to:

• Normal energy-yielding metabolism

• Normal functioning of the nervous system

• Normal psychological function

• Normal red blood cell formation

• Normal immune function

• Reduction of tiredness and fatigue

Vitamin B12 is naturally found mainly in animal-derived foods, including meat, fish, eggs and dairy products.

Who should particularly consider B12?

Women following a vegan diet need to pay particular attention to vitamin B12 because plant foods do not naturally provide reliable amounts.

Vegetarians may also need to consider their intake depending on the foods they eat.

B12 absorption can also become less efficient as we age.

5. Magnesium – One of the Most Popular Women's Supplements

Magnesium has become one of the most talked-about supplements in women's wellness – and it has several recognised functions in the body.

Magnesium contributes to:

• Reduction of tiredness and fatigue

• Normal functioning of the nervous system

• Normal psychological function

• Normal muscle function

• Maintenance of normal bones

• Normal energy-yielding metabolism

• Electrolyte balance

Good dietary sources include nuts, seeds, wholegrains and leafy green vegetables.

A magnesium supplement may be considered if your dietary intake is insufficient, but check whether your existing multivitamin already contains it before adding another product.

6. Calcium – Think About Your Bones

Calcium isn't only important during childhood.

Women should continue thinking about bone health throughout adulthood, particularly as they approach menopause.

Calcium is needed for the maintenance of normal bones and teeth and also contributes to normal muscle function.

Good sources include:

• Milk

• Yoghurt

• Cheese

• Calcium-fortified plant milks

• Some green vegetables

• Tinned fish where the soft bones are eaten

Women who consume little or no dairy should pay particular attention to alternative calcium sources.

Rather than automatically taking a calcium supplement, look at how much you're getting through your diet first.

7. Omega-3 – An Important Part of a Healthy Diet

Omega-3 fatty acids aren't vitamins, but they're another popular part of women's daily supplement routines.

The omega-3 fatty acids EPA and DHA contribute to the normal function of the heart when consumed at appropriate daily levels.

Good dietary sources include oily fish such as:

• Salmon

• Mackerel

• Sardines

• Herring

• Trout

If you rarely eat oily fish, you may want to consider an omega-3 supplement.

Vegetarian and vegan alternatives containing omega-3 derived from algae are also available.

8. B Vitamins – Everyday Energy Support

The B-vitamin family includes B1, B2, B3, B5, B6, biotin, folate and B12.

Different B vitamins perform different functions, but collectively they're involved in areas such as energy metabolism, the nervous system, psychological function and blood formation.

Vitamin B6, for example, contributes to:

• Normal energy-yielding metabolism

• Normal psychological function

• Normal functioning of the nervous system

• Regulation of hormonal activity

• Reduction of tiredness and fatigue

A balanced diet usually provides a range of B vitamins, so taking a high-strength B-complex isn't automatically necessary.

9. Vitamin C – More Than Immune Support

Vitamin C is probably best known for supporting the immune system, but it performs several other important functions.

Vitamin C contributes to:

• Normal function of the immune system

• Protection of cells from oxidative stress

• Normal collagen formation

• Normal function of skin

• Reduction of tiredness and fatigue

• Increased iron absorption

Fruit and vegetables can provide plenty of vitamin C, particularly peppers, berries, citrus fruits, broccoli and other fresh produce.

If you regularly eat a varied diet rich in fruit and vegetables, you may already be getting enough.

10. Zinc – Skin, Hair, Nails & Immunity

Zinc is another useful mineral to know about.

It contributes to:

• Maintenance of normal hair

• Maintenance of normal skin

• Maintenance of normal nails

• Normal function of the immune system

• Normal fertility and reproduction

• Protection of cells from oxidative stress

Zinc is available through foods including meat, shellfish, dairy products, bread, seeds and nuts.

Again, more isn't necessarily better. Check the amount in your multivitamin before adding a separate zinc supplement.

Should Women Take a Multivitamin Every Day?

A good-quality women's multivitamin can be a convenient option, particularly if your diet isn't always as varied as you'd like.

Instead of opening five or six different bottles every morning, a multivitamin can provide a broad range of vitamins and minerals in one product.

However, a multivitamin shouldn't be viewed as a substitute for healthy food.

Think of it as nutritional support rather than nutritional insurance for an unhealthy diet.

Vitamins for Women by Life Stage

Women in Their 20s & 30s

Priorities may include:

• Folic acid if pregnancy is possible

• Vitamin D

• Iron if required

• B12, particularly for vegans

• Omega-3 if oily fish intake is low

• A balanced multivitamin where appropriate

Women in Their 40s

Alongside general nutritional needs, it can be useful to start paying greater attention to:

• Vitamin D

• Calcium

• Magnesium

• B vitamins

• Omega-3

Women entering perimenopause may also wish to consider a dedicated perimenopause supplement.

Women 50+

As menopause approaches or occurs, nutritional priorities can change.

Particular attention may be given to:

• Vitamin D

• Calcium

• Magnesium

• B12

• Omega-3

• Overall protein and nutritional intake

After periods stop, iron requirements generally reduce, so an iron-containing women's multivitamin may no longer be necessary unless a healthcare professional has recommended it.

What About Hair, Skin & Nail Vitamins?

Biotin, zinc, selenium and vitamin C are commonly found in beauty supplements.

Biotin contributes to the maintenance of normal hair and skin, while zinc contributes to normal hair, skin and nails. Selenium contributes to the maintenance of normal hair and nails.

However, if you're suddenly experiencing significant hair loss, brittle nails or changes to your skin, don't automatically assume you need a beauty supplement.

Hair loss, for example, can sometimes be associated with iron deficiency, thyroid problems, hormonal changes or other conditions.

Speak to your GP or pharmacist if changes are significant or persistent.

Can I Take All My Vitamins Together?

Many standard vitamins can be taken together, which is why they're combined in multivitamin products.

However, certain minerals and medicines can interact or compete for absorption.

If you take prescription medication or several different supplements, ask your pharmacist to review everything together.

It's particularly important to avoid unintentionally doubling up by taking a multivitamin plus several separate supplements containing the same nutrients.

Food First, Supplements Second

Supplements are designed to supplement your diet, not replace it.

Try to build your daily nutrition around:

• Plenty of vegetables and fruit

• Wholegrains

• Protein-rich foods

• Nuts and seeds

• Calcium-rich foods

• Healthy fats

• Oily fish where appropriate

• Plenty of water

Then use supplements strategically where your diet, lifestyle or life stage leaves a nutritional gap.

A Simple Daily Supplement Routine for Women

If you're confused by dozens of different supplements, keep things simple.

For many women, a sensible approach is:

1. Start with vitamin D according to Irish recommendations.

2. Take 400 mcg folic acid daily if you could become pregnant.

3. Consider a women's multivitamin if your diet is inconsistent or you have specific nutritional requirements.

4. Consider omega-3 if you rarely eat oily fish.

5. Add individual supplements such as iron, B12, calcium or magnesium only when they're appropriate to your diet and individual needs.

The best supplement routine isn't necessarily the one containing the most products. It's the one that's appropriate for you.

Frequently Asked Questions

What vitamins should every woman take daily?

There isn't a universal list that every woman needs to supplement. Vitamin D is particularly important to consider in Ireland, while women who could become pregnant should take 400 mcg of folic acid every day. Other supplements depend on diet, age and individual requirements.

Is it good to take a women's multivitamin every day?

A multivitamin can help complement your diet, but it isn't essential for every healthy woman eating a balanced and varied diet. Choose one appropriate for your age and life stage.

Should women take vitamin D every day?

Irish vitamin D recommendations depend on age, skin type, pregnancy and sun exposure.

Healthy adults aged 12–65 with fair skin and adequate summer sun exposure are advised to take 15 mcg (600 IU) daily from the end of October to March, while some groups are advised to supplement throughout the year.

Should women take iron every day?

Not necessarily. Women who menstruate have higher iron requirements, but that doesn't mean everyone needs an iron supplement. If you have heavy periods or symptoms of iron deficiency, speak to your GP about testing.

Should women take magnesium every day?

Magnesium is essential, but many women can obtain it through food. Supplementation may be considered when dietary intake is inadequate or where advised by a healthcare professional.

What vitamins should women over 40 take?

Vitamin D, calcium, magnesium, B vitamins and omega-3 are commonly considered at this stage, but requirements depend on diet, health and whether you're approaching perimenopause.

What vitamins should women over 50 take?

Vitamin D and calcium become particularly important considerations for bone health, while B12, magnesium and omega-3 may also deserve attention depending on diet and individual requirements.

Is it okay to take several supplements every day?

It can be, but check the labels carefully. Taking a multivitamin alongside individual vitamin and mineral supplements can lead to duplication and unnecessarily high doses.
