Top Ten Nutrients for Healthy Ageing
September is Healthy Ageing Month, a good reminder that getting older does not have to mean simply accepting low energy, poor mobility, brain fog, aches and pains or a steady decline in health.
Many people are living longer than ever before, but living longer is not quite the same as living well.
In the UK, around one in five people are now aged 65 or older, and healthy life expectancy is much lower than overall life expectancy. The latest ONS figures show that healthy life expectancy at birth in the UK is around 61 years, which means many people may spend a significant number of later-life years in less-than-optimal health.
That can sound a little sobering, but I want this article to feel encouraging.
Because it is never too late to support your body.
The food you eat, the nutrients you absorb, the way you move, your sleep, your digestion, your stress levels and your daily habits can all make a difference to how well you age.
Nutrition is not the only answer, of course, but it is a very important foundation.
So let’s look at ten key nutrients and foods that can help support healthy ageing.
No time to read? You can watch my previous video on the top ten nutrients for healthy ageing below.

Top Ten Nutrients for Healthy Ageing
1. Omеgа-3 Essential Fatty Acids, especially EPA/DHA.
Omega-3 fats are always top of my list.
They are called “essential” because the body cannot make them, so they must come from the diet.
The most reliable food sources are oily fish, such as mackerel, sardines and wild Alaskan salmon.
These fats have an anti-inflammatory action in the body and help balance the inflammatory effects of excess omega-6 fats, processed fats and too much sugar.
Omega-3 fats are important for brain health, cardiovascular health, joint health and many inflammatory conditions. The brain itself is rich in fatty acids, which is one reason I think about omega-3 intake when supporting memory, mood and cognitive health as we age.
To obtain a good intake from food, aim for around three portions of oily fish each week. If you do not eat oily fish regularly, a good quality EPA/DHA supplement may be worth considering.
You can read more about healthy fats here: Why Healthy Fats Are Important for Your Gut, Brain and Overall Health.
And how nutrition is only one part of the picture. Did you know that meal timing could help brain health and reduce dementia risk?.
2. Vitamin D3
Vitamin D3 is essential for the immune system, strong bones, muscle function and brain health.
Older adults are more likely to be at risk of low vitamin D because they may spend more time indoors, cover up more when outside, or have less exposure to sunlight on bare skin.
In the UK, we cannot make enough vitamin D from sunlight during the autumn and winter months. NHS guidance recommends that adults consider taking a daily vitamin D supplement during autumn and winter, and that people at higher risk of deficiency may need to consider supplementation throughout the yearm 1000IU every day, 365 days of the year.
This is especially important for older adults, those who are housebound, people who cover most of their skin, and those with darker skin.
Vitamin D is one nutrient where testing can be very helpful, especially if you are tired, achy, low in mood or concerned about bone health.
3. Magnesium
Magnesium is a miracle mineral in my mind, yet it often lives in the shadow of calcium.
It is involved in hundreds of processes in the body and is one of the first nutrients I think about when clients present with headaches, cramps, poor sleep, anxiety, low mood, low energy, osteoporosis, asthma or cardiovascular concerns.
Magnesium is required for a healthy nervous system, energy production, muscle contraction and relaxation, and strong bones.
It is also known as nature’s tranquilliser because it can be so supportive for stress, anxiety and sleep.
Good food sources include dark green leafy vegetables, avocados, nuts, seeds, pulses and wholegrains such as brown rice.

4. Curcumin
Curcumin is the active ingredient in turmeric.
This golden spice has many valuable health properties, especially because of its anti-inflammatory action.
That matters for healthy ageing because inflammation can play a role in many ongoing health concerns, including joint pain, inflammatory bowel conditions and brain ageing.
Curcumin may help support memory and brain health, and I often think about it when looking at inflammation in the body.
The one thing to be aware of is that curcumin is poorly absorbed from the gut into the bloodstream. If you use it in cooking, add it to healthy fats such as olive oil or coconut oil. If choosing a supplement, look for a well-absorbed formula.
5. Vitamin C
Vitamin C is an important antioxidant, helping to protect cells against damage and ageing.
It also supports wound healing and is needed for collagen production. Collagen is not only important for keeping skin plump, but also for bones, tendons, ligaments and connective tissue.
Good food sources include peppers, kiwi fruit, citrus fruits, berries and dark green leafy vegetables.
This is where food quality and variety really matter. Brightly coloured fruit and vegetables provide a wide range of antioxidants that help support healthy ageing.

6. Zinc
Zinc is a critical nutrient for the development and function of the immune system.
It is involved in hundreds of enzyme processes, including energy metabolism, nerve function, digestion, skin health and wound healing.
For men specifically, sufficient zinc intake may also support prostate health.
Good sources include nuts, seeds, especially pumpkin seeds, shellfish, red meat, legumes and eggs.
Because zinc is so important for immunity, skin, fertility and healthy ageing, it is one of those nutrients I do not want people to overlook.
7. Vitamin B12
Vitamin B12 nourishes the brain and nervous system.
It is also required for red blood cell production, so low levels can contribute to tiredness, weakness and anaemia-type symptoms.
B12 is found mainly in animal foods, which means vegans and some vegetarians need to be particularly mindful of their intake. A deficiency can take years to become apparent, so it is important not to wait until symptoms become obvious.
Low B12 can also become more common with poor digestion, low stomach acid or absorption issues, which is why I always come back to the importance of digesting and absorbing food well.
Chew your food properly, eat slowly, support your digestion and consider testing if you are concerned.

8. B Vitamins
B vitamins work best together, which is why they are often taken as a complex.
They play a crucial role in energy production, DNA repair, immune health, mood and brain function.
They also help lower a substance called homocysteine. High homocysteine levels have been linked with Alzheimer’s and cardiovascular disease.
Good food sources include legumes, meat, fish, eggs, dark green leafy vegetables and wholegrains such as brown rice.
If you are tired, stressed, low in mood or feeling mentally foggy, B vitamins are worth considering as part of the wider picture.
9. Co Q10
CoQ10 is an important antioxidant and energy producer.
It is found in abundance in heart cells, but it is important for energy generation in cells throughout the body.
CoQ10 naturally becomes more important to consider as we age, especially when thinking about cardiovascular health, energy and vitality.
It is also important to know that statins can lower levels of CoQ10. This is why I often recommend considering CoQ10 supplementation for those taking statins, but always alongside appropriate medical guidance.
Food sources include organ meats, oily fish and wholegrains.
10. Fibre
Fibre is not a nutrient in the same way as vitamins and minerals, but it is essential throughout life and especially as we age.
Fibre supports healthy elimination, helping the body clear waste and toxins through the bowel.
It also feeds the gut microbiome, which we now know plays a role in many aspects of health, including digestion, immunity, mood, inflammation and brain health.
Low fibre intake is linked with poorer bowel health, and bowel concerns become more common as we age.
To support fibre intake, aim for a diverse and colourful range of vegetables, herbs, nuts, seeds, legumes and whole foods.
I often encourage people to aim for variety rather than perfection.
Different fibres feed different beneficial gut bacteria, so diversity really matters. You can read more about Fibre for Gut Health: Soluble vs Insoluble to see what would work for you.
Food Quality Matters Too
When we talk about nutrients for healthy ageing, we also have to talk about food quality.
A diet rich in vegetables, herbs, good fats, quality protein, fibre and antioxidant-rich foods will always be the foundation.
But the quality of the food matters too.
This is where organic food can sometimes fit into the conversation. Organic fruit and vegetables may have higher antioxidant levels, and choosing organic may also help reduce exposure to pesticide residues.
That does not mean you have to buy everything organic.
If cost is a concern, I’ve written a practical guide on whether organic food is worth the cost and how to choose organic wisely here: Is Organic Food Worth the Cost?
Final Thought
Healthy ageing is not about fighting age or trying to turn back the clock. It is about supporting your body so you can feel as well, strong, clear and energised as possible for as long as possible.
These ten nutrients are a wonderful place to start: omega-3 fats, vitamin D3, magnesium, curcumin, vitamin C, zinc, B12, B vitamins, CoQ10 and fibre.
But remember, nutrients do not work in isolation.
They work best as part of a varied, colourful, real-food diet, alongside good digestion, movement, sleep, stress support and a lifestyle that feels manageable.
Start with one small change… Add more oily fish. Eat more colourful vegetables. Try more fibre. Check your vitamin D.
