The Best Vitamins for Women Over 40: What Your Body Needs as You Age
When I turned 40, I was very excited about my party, where I will be celebrating with my family and friends, this was an important milestone.
We all had a great night with so many tequila shots and dancing most of the night. My joints very aching and my head was like a shooting star when I turned 40 years and one day. This is when I realised I need to pay a lot more attention to my body.
Eventually, I noticed changes in my energy levels, sleep, mood, skin, weight and menstrual cycle. I responded differently to exercise and diet. While, I would diet for few weeks and lost all the unwanted weight in my thirties, that wasn’t the case anymore. This wasn’t isolated to me, most of my friends complained of the same thing.
These changes are often associated with hormonal fluctuations, particularly during perimenopause and menopause.
One question I was often asked: What are the best vitamins for women over 40’s?
This is my summary of what we need to look for:
1. Vitamin D – Essential for Strong Bones
Vitamin D is one of the most important nutrients to consider as women get older.
It helps the body absorb calcium, supports bone health and plays an important role in normal muscle and immune function.
As women approach menopause, declining oestrogen levels can contribute to a reduction in bone density. This makes maintaining adequate vitamin D and calcium intake particularly important.
Where can you get it?
Vitamin D is produced by the skin following exposure to sunlight. Small amounts are also found in foods such as oily fish, eggs and fortified products.
Women with limited sun exposure or low vitamin D levels may benefit from supplementation following professional advice, make sure you discuss this with your pharmacist to get the best possible options.
2. Vitamin B12 – Supporting Energy and Brain Function
Do you sometimes feel tired, mentally foggy or lacking in energy?
Vitamin B12 is essential for red blood cell formation, normal nervous system function and DNA production.
Some women may become more susceptible to vitamin B12 deficiency as they age, particularly if you are vegetarian.
Certain medications can also affect vitamin B12 absorption.
Where can you get it?
Vitamin B12 is naturally found in animal-based foods, including:
-
Eggs.
-
Fish.
-
Meat.
-
Milk and dairy products.
Vegetarians and vegans may need fortified foods or a B12 supplement.
If you are experiencing persistent fatigue, make sure you do a blood test.
3. Magnesium – Important for Muscles, Nerves and Sleep
Magnesium is an essential mineral involved in hundreds of processes in the body.
It plays a role in muscle and nerve function, energy production and maintaining healthy bones.
Many women become interested in magnesium during perimenopause and menopause, particularly when experiencing changes in sleep, muscle discomfort or stress.
However, magnesium supplements are not a proven treatment for all menopause symptoms.
Where can you get it?
Good dietary sources include:
-
Almonds and cashews.
-
Pumpkin seeds.
-
Spinach and leafy green vegetables.
-
Whole grains.
-
Legumes.
A magnesium supplement may be worth discussing with your pharmacist or healthcare professional if your dietary intake is insufficient. I wouldn’t take just another magnesium supplement as the right magnesium salt is essential for absorption.
4. Calcium – Protecting Your Bones as You Age
Bone health deserves particular attention after 40.
During perimenopause and menopause, declining oestrogen levels can accelerate bone loss. Over time, this may increase the risk of osteoporosis.
Calcium is essential for maintaining strong bones and teeth.
For Australian women, the recommended daily calcium intake is generally:
-
Women aged 19–50: 1,000 mg.
-
Women aged 51 and over: 1,300 mg.
These amounts include calcium obtained from food and supplements. There are many cheap calcium supplements available in the market, I would recommend to discuss this with your pharmacist or naturopath to choose the correct one.
Where can you get it?
-
Milk, cheese and yoghurt.
-
Calcium-fortified plant-based milk.
-
Sardines and salmon with edible bones.
-
Calcium-set tofu.
-
Some green vegetables.
5. Iron – Particularly Important for Women Still Having Periods
Iron is essential for producing haemoglobin, the protein in red blood cells responsible for transporting oxygen around the body.
Women in their forties may experience heavier or irregular periods during perimenopause. This can increase the risk of iron deficiency.
Low iron levels may contribute to fatigue, weakness, dizziness and reduced exercise tolerance.
Where can you get it?
-
Red meat.
-
Chicken and fish.
-
Lentils and beans.
-
Spinach.
-
Iron-fortified cereals.
An important point: iron supplements should not be taken routinely without a reason. Excess iron can be harmful, and women who have gone through menopause generally have lower iron requirements.
If you experience unexplained tiredness, ask your doctor to check your iron level.
6. Vitamin C – Supporting Skin and Collagen Production
As we age, our skin naturally changes. Collagen production declines, and many women notice changes in skin firmness, texture and elasticity.
Vitamin C is an important nutrient involved in normal collagen formation.
It also acts as an antioxidant and supports normal immune function.
Where can you get it?
-
Oranges and mandarins.
-
Kiwi fruit.
-
Strawberries.
-
Capsicum.
-
Broccoli.
A balanced diet containing plenty of fruit and vegetables is an excellent way to obtain vitamin C.
Should Women Over 40 Take a Multivitamin?
A good-quality multivitamin may help fill nutritional gaps, particularly if your diet is restricted or you struggle to consume a variety of nutritious foods.
However, not every woman needs a daily multivitamin.
The best approach is to identify your individual nutritional needs rather than automatically taking multiple supplements.
When choosing a multivitamin, consider:
-
Your age and stage of life.
-
Your dietary habits.
-
Whether you are still menstruating.
-
Your current medications.
-
Any confirmed nutritional deficiencies.
-
Whether you are approaching or experiencing menopause.
Remember that taking more vitamins does not necessarily mean better health. Some nutrients can be harmful in excessive amounts.
While I have been lucky compared to all my friends and I still haven’t experienced menopause, I am sure I am going through pre-menopause.
For many women, their forties and fifties bring significant hormonal changes.
Perimenopause can begin several years before menopause and may involve:
-
Hot flushes and night sweats.
-
Changes in sleep patterns.
-
Mood fluctuations.
-
Brain fog and difficulty concentrating.
-
Changes in menstrual cycles.
-
Vaginal dryness.
-
Changes in body composition.
Good nutrition, regular exercise, adequate protein intake, quality sleep and appropriate healthcare all play important roles during this stage of life.
One key word that explains pre-menopause and menopause is inflammation. This requires substantial attention that we will target in the next topic.
Supplements may help address specific nutritional needs, but vitamins alone are not a treatment for hormonal changes or menopause symptoms.
If symptoms are affecting your quality of life, speak with your GP about the available treatment options, including menopause hormone therapy where appropriate.
Our Top Tips for Women Over 40
At Respect Health, we believe that looking after your health should be proactive rather than reactive.
Here are seven simple habits worth incorporating into your daily routine:
-
Prioritise protein: Include quality protein with your main meals to help maintain muscle mass.
-
Eat foods that are easy to digest so reduces your gut inflammation.
-
Look after your bones: Maintain adequate calcium and vitamin D intake.
-
Stay physically active: Combine walking with resistance and weight-bearing exercises.
-
Prioritise sleep: Establish a consistent bedtime routine.
-
Manage stress: Make time for activities that support your mental wellbeing.
-
Check your health: Discuss appropriate blood tests and preventive health checks with your GP.
I have to accept that our forties are the beginning of ageing – however, we shouldn’t easily accept this for our body and we need to start looking after our body better.
Understanding your nutritional needs, staying physically active and addressing deficiencies early can help support your health as you move through perimenopause, menopause and beyond.
Rather than following every supplement trend, focus on what your body actually needs.
At Respect Health, we believe every woman deserves access to reliable health information and personalised support to make informed decisions about her wellbeing.
