Why Women Over 40 Need Supplements

Perimenopause brings a drop in oestrogen, and at the same time, your body becomes less efficient at pulling nutrients from food. So even with a good diet, a gap opens up between what your body needs and what it actually gets. Your energy needs dip slightly, while your need for several key nutrients goes up.

The gaps

Three things shift at once.

1. Your hormones increase the rate at which bone breaks down and rebuilds, making it harder to maintain muscle.
2. The stomach produces less acid, which makes it harder to absorb nutrients like vitamin B12, while the skin becomes less efficient at producing vitamin D from sunlight.
3. Appetite often decreases just when the body actually needs more nutrients.

This is simply the gap, and the gap is what good supplementation is built to close.

Can’t I just get it from food?

Food is the foundation, always. But modern produce is often lower in minerals, processing strips others, and some nutrients are genuinely hard to get from food at all. Vitamin D is the clearest case: in the UK, official guidance recommends a daily supplement through autumn and winter, because diet and limited sunlight rarely provide enough. Good supplementation fills specific, evidence-based gaps.

The nutrients most worth your attention

• Vitamin D. Contributes to normal bones, muscle function and immunity. Hard to get from food and UK light.
• Magnesium. Contributes to reduced tiredness, normal muscle and psychological function. Choose bisglycinate over oxide.
• Omega-3 (EPA & DHA). Contribute to normal heart function. Mainly from oily fish, easy to fall short on.
• B vitamins, especially B12. Support energy metabolism and reduced fatigue. Absorption declines with age.
• Calcium. Needed for normal bones. Works alongside vitamin D, magnesium and protein.
• Protein and collagen. Protect muscle, skin and joints. Collagen drops sharply as oestrogen falls. More on collagen after 40.

How to choose well

Supplements are not a substitute for sleep, protein, strength training or managing stress. Used on top of those foundations, the ones worth taking share a few things in common:

• Clinically meaningful doses, the amount used in the research, not a token sprinkle.
• Bioavailable forms your body can actually absorb and use.
• Formulated for women over 40, not a generic multivitamin for everyone.

The goal isn’t more of everything. It’s the right things, at the right doses for you.

Perimenopause and menopause is the life stage where needs and gaps peak, as oestrogen falls and affects bone, muscle, mood and sleep. Evidence-led supplements at clinically meaningful doses can support those changing needs, alongside diet, movement and sleep.
