Turning 40 often brings a fresh look at nutrition, and the supplement aisle does not make it easy. This guide walks through the nutrients most commonly discussed for women in midlife, what the research actually supports, and where a conversation with your GP matters more than any label.
Key takeaways
- Nutrients, not miracles. Vitamin D, magnesium, vitamin B12, iron and omega-3 are the building blocks worth understanding first, because several carry approved health claims and are genuinely easy to fall short on.
- Vitamin D does real work. It contributes to the maintenance of normal bones and to normal muscle function, which is why it comes up so often for women thinking about long-term bone health.
- Magnesium is a quiet workhorse. It contributes to a reduction of tiredness and fatigue, to normal psychological function and to normal muscle function.
- Adaptogens are interesting, not proven. Herbs like ashwagandha have been studied, but they carry no approved UK health claims, so treat them as an area of research rather than a promise.
- Your GP comes first. Around menopause, or if you take medication or manage thyroid or other conditions, professional advice should lead your choices, not a supplement label.
Why midlife changes the nutrition picture
The years around 40 and beyond bring gradual shifts in hormones, bone turnover and how the body handles certain nutrients. None of this means something is wrong, but it does change which gaps are worth watching. Bone maintenance becomes a more common topic of conversation, energy levels can feel less predictable, and dietary patterns often change as life gets busier.
Supplements are not a substitute for a varied diet, and they are certainly not a treatment for menopause or any medical condition. What a sensible supplement routine can do is help top up specific nutrients that are hard to get consistently from food, especially for anyone eating a plant-based or restricted diet. The honest approach is to understand each nutrient on its own terms rather than reaching for a product that promises to fix everything.
The nutrients worth understanding first
These are the ones with the strongest evidence base and, importantly, the ones that carry approved UK claims you can rely on.
- Vitamin D. Vitamin D contributes to the maintenance of normal bones and to normal muscle function, and it contributes to the normal function of the immune system. In the UK, official advice suggests considering a daily supplement during autumn and winter, when sunlight is limited. Our Super Greens Gummies provide Vitamin D3 at 2,000 IU, which is 1000% of the NRV.
- Calcium and bone health. Calcium works alongside vitamin D in the context of bone maintenance. Dairy, fortified plant milks, tofu and leafy greens are the usual dietary sources, and it is worth reviewing your intake with your GP before adding a calcium supplement, since needs vary a great deal from person to person.
- Magnesium. Magnesium contributes to a reduction of tiredness and fatigue, to normal energy-yielding metabolism, to normal psychological function, to the normal functioning of the nervous system and to normal muscle function. It is one of the more commonly under-consumed minerals.
- Vitamin B12. Vitamin B12 contributes to normal energy-yielding metabolism, to the reduction of tiredness and fatigue and to the normal function of the immune system. It is found almost entirely in animal foods, so anyone eating less meat or a fully plant-based diet should pay particular attention here.
- Vitamin B6. Vitamin B6 contributes to normal energy-yielding metabolism, to the reduction of tiredness and fatigue and to normal psychological function.
Iron, omega-3 and iodine considerations
A few more nutrients deserve a mention, with more nuance attached.
Iron. Iron needs can shift through the perimenopausal years. Some women need more, others need less once periods become lighter or stop, and too much iron is not harmless. This is precisely the kind of decision to make with a blood test and your GP rather than by guessing, so we would not suggest self-prescribing an iron supplement based on a guide like this one.
Omega-3. Omega-3 fatty acids are widely discussed for general wellbeing in midlife. Oily fish is the classic source, and algae-based options exist for anyone avoiding fish. The evidence here is genuinely mixed depending on the outcome being measured, so treat it as a reasonable addition to a balanced diet rather than a guaranteed benefit.
Iodine. Iodine contributes to normal thyroid function, to normal energy-yielding metabolism and to normal cognitive function. Sea vegetables are a natural source, and our Sea Moss with Bladderwrack & Burdock Gummies provide Irish Sea Moss and Bladderwrack as a natural source of iodine. Because iodine intake interacts closely with thyroid health, and thyroid conditions become more common with age, this is another area to raise with your GP before starting, especially if you already have a diagnosed thyroid issue. You can read more in our guide to vegan iodine sources.
What about adaptogens like ashwagandha
Adaptogens have become a fixture in wellness conversations, and ashwagandha is the one you will hear about most. It is worth being clear about what can and cannot be said. Ashwagandha and similar herbs carry no approved UK health claims, so we cannot tell you a product will deliver a specific benefit. What we can say is that researchers have studied standardised extracts such as KSM-66, and studies have measured a range of outcomes, with results that continue to be explored rather than settled.
Our Ashwagandha & Lion's Mane Gummies use KSM-66 Ashwagandha at 2,500 mg alongside Lion's Mane, Ginkgo Biloba, Magnesium and vitamins B6 and B12. The magnesium and B vitamins in that formula are the components with approved claims, including magnesium and B6 contributing to normal psychological function. If you want to understand the state of the evidence before deciding, our overview of the ashwagandha and stress research lays out what studies have and have not measured. Treat adaptogens as an interesting area to explore with realistic expectations, not as a solution to any midlife symptom.
What to actually look for
Once you know which nutrients matter to you, the label tells you whether a product is worth buying. Here is what separates a considered formula from a disappointing one.
- Dose transparency. Every active ingredient should show its amount per serving. Vague blends that hide quantities make it impossible to know whether you are getting a meaningful dose or a token sprinkle.
- Standardised extracts. Where herbs are involved, standardised extracts such as KSM-66 for ashwagandha give more consistency than generic powders of unknown strength.
- Third-party testing. Independent testing confirms that what is on the label is what is in the bottle. All of our gummies are third-party tested and made in the UK.
- Vegan formulation. If you avoid animal products, check the base. Our range is pectin-based rather than gelatine, so it suits plant-based diets.
- Avoiding under-dosing. A long ingredient list at tiny amounts is a common trap. Fewer ingredients at honest doses usually serves you better than a crowded label.

Building a routine that lasts
The best supplement is the one you actually remember to take. Consistency matters far more than chasing the newest ingredient, so it helps to anchor your routine to something you already do every day, such as breakfast. Gummies suit this well because they need no water and are easy to keep by the kettle or on the counter. Start with the one or two nutrients most relevant to you rather than overhauling everything at once, and give any change several weeks before judging it. Our guide to building a daily supplement routine that sticks covers the practical habits that make this easier.
Above all, keep your GP in the loop. If you are pregnant, breastfeeding, taking medication, going through menopause or managing any condition, speak to your GP before starting a new supplement. That single conversation is worth more than any product claim, and it is the responsible way to make midlife nutrition decisions.
Common questions
Do women over 40 need different supplements?
Not dramatically different, but the emphasis often shifts. Bone maintenance, energy and, for anyone eating fewer animal foods, vitamin B12 tend to come up more. The sensible move is to look at your own diet and blood work with your GP rather than assuming your age alone dictates what you need.
Can supplements help with menopause symptoms?
Supplements are not a treatment for menopause or any medical condition, and we would not claim otherwise. Some nutrients, such as vitamin D for bone maintenance and magnesium for tiredness and fatigue, support normal functions that matter through midlife, but managing menopause itself is a medical conversation for your GP.
Is it safe to take several supplements together?
Often yes, but not always, and some nutrients and medications interact. Iron and iodine in particular deserve caution. The safest approach is to list everything you take, including supplements, and review it with your GP or pharmacist so nothing works against you.
Are gummies as effective as capsules?
What matters is the dose and quality of what is inside, not the format. A well-dosed, third-party-tested gummy can serve you just as well as a capsule, and many people find they are more consistent with a format they enjoy taking.
