High Phenolic Olive Oil After 40

PRACTICAL SUPPORT FOR BLOOD PRESSURE, JOINTS AND EVERYDAY ENERGY 

In a few words:

After 40, oxidative stress and inflammation start playing a bigger role in heart, joint and bone health. High phenolic olive oil won't fix any of this on its own, but its polyphenols have real research behind them, including an EFSA-approved claim for protecting blood lipids from oxidative stress. Swap your everyday oil for a lab-tested high phenolic one, use it daily, and pair it with the basics - movement, sleep, and a plate with some colour on it.

Even for the healthiest of us, forty doesn’t arrive quietly. Blood pressure creeps up, joints that never used to complain start making themselves known after a long walk, energy dips a little earlier in the afternoon, and recovery just isn’t quite as quick as it used to be.

None of this is a crisis; it's just the body asking for a bit more support than it used to need - a natural process of ageing! So here’s what actually matters after 40, what the research says, and how to use it properly

Why 40 is a turning point

None of this happens overnight, and none of it is really about a birthday. It’s more a gradual change in how the body responds to everyday stress: recovery from exercise or a bad night’s sleep takes a little longer, cardiovascular risk starts to rise, and it’s also the decade the NHS flags for a routine health check.

The NHS Health Check is offered to everyone aged 40 to 74 simply because this is the stage of life where a few common conditions can start to show up quietly - and it makes sense to catch them early while they’re still easy to manage.

Why phenols matter more as you get older

As we get older, the body naturally deals with a bit more oxidative stress and low-grade inflammation. Nothing dramatic, just the kind of background wear and tear that’s been linked with things like heart health, joint stiffness, and that slow dip in energy many people start to notice from their 40s onwards. 

Polyphenols are the plant compounds thought to help the body handle some of that load. We’ve gone into this in more detail on the benefits of polyphenol intake in our article on olive oil and longevity, where we look at what the research actually says and how it fits into the bigger picture.

The important bit is that not all olive oils give you much of them. Typical supermarket extra virgin olive oil often sits around 50-200 mg/kg of polyphenols. A true high-phenolic oil is a different category entirely - usually early-harvested, cold-pressed, and independently tested well above that, often 500 mg/kg and beyond.

If you want to see what that looks like, take a look at our NOVEMBER guide - it breaks down how our oils compare with what you’ll usually find on the shelf.

Blood pressure and heart health

Olive oil for heart health tends to become a bigger focus after 40, and for good reason. Around 1 in 4 adults in the UK have high blood pressure, often without any symptoms at all. 

It's a common reason people ask whether extra virgin olive oil is good for high blood pressure, and also why the NHS offers free health checks from age 40 onwards - available through your GP and, in many areas, local pharmacies too.

• Polyphenols help olive oil reduce cholesterol oxidation - protecting LDL from the process linked with arterial health.

• Diets that regularly include olive oil, such as the Mediterranean diet, are associated with healthier blood pressure and circulation.

• The British Heart Foundation highlights olive oil as a source of heart-healthy monounsaturated fat, best used in place of saturated fats rather than alongside them.

It’s worth being clear on this: this isn’t a treatment for high blood pressure, and it won’t replace any prescribed medication. If blood pressure is something you’re keeping an eye on, it’s always worth speaking to your GP alongside any dietary changes. The NHS also has straightforward, practical guidance on managing it if you want to read more.

Joints and everyday stiffness

Stiffness or joint aches after activity are common complaints from your 40s onward. Polyphenols, and one in particular called oleocanthal, have anti-inflammatory properties that researchers have compared to ibuprofen, though at a far gentler intensity from diet alone.

This is a big enough topic that we've written about it in more depth - see our guide on olive oil and arthritis for the fuller picture on joint health and inflammation.

Olive oil for bone strength

A common question at this stage is whether olive oil is good for bones and joints as well as heart health. Bone density naturally starts to decline from the mid-30s, and the drop can speed up in some circumstances - most notably around the menopause, as we've covered in more depth in our women's health guide. 

Diet alone won't offset that shift, but a Mediterranean-style diet, rich in olive oil, vegetables, oily fish, and calcium sources, is one of the lifestyle factors that supports bone and joint health more broadly, alongside weight-bearing exercise. 

Choosing the right olive oil for this stage of life

Not every bottle labelled "extra virgin" delivers a meaningful polyphenol dose, and picking the wrong one is the easiest way to undo everything above before you've even started. We’ve gone into how to read a label properly, including mg/kg figures, harvest dates, all of that, in our How to Buy Olive Oil guide, so we won’t repeat it here.

The short version is simple: Masworth Family Groves sits at 965 mg/kg, and NOVEMBER Polyphenols, our early-harvest Cretan oil, certified at 1,200+ mg/kg by the World Olive Centre for Health in Athens, is designed for exactly the kind of daily, consistent use this stage of life calls for.

They’re among the higher end of what's available in the UK - and well clear of the EU threshold for the official health claim.

Making high phenolic extra virgin olive oil a daily habit

1-2 tablespoons a day, used consistently, is the sweet spot - and the swaps that matter most at this stage are the ones replacing less helpful fats you're already eating.

• Swap the butter on your morning toast for a good olive oil and a pinch of salt. 

• Trade shop-bought dressings, often high in salt, for a squeeze of lemon and a spoon of olive oil on your lunch salad. 

• Use it in place of cream or butter to finish soups - an easy win if blood pressure is on your radar. 

• Keep the heat gentle. High phenolic oil is best used raw or added at the end of cooking; sustained high heat degrades the phenols that make it worth choosing in the first place.

Like most things at this stage, it’s consistency that really counts. A small, steady daily habit tends to go further than the occasional big effort.

Why olive oil matters after 40

From 40 onwards, things like oxidative stress and low-grade inflammation start to play a bigger role in how the body feels day to day - from heart health to joints and general energy.

A high-phenolic olive oil is one small, evidence-backed change you can make here. It’s not a fix-all, and it’s not a replacement for medical advice on things like blood pressure or cholesterol, but there’s a wealth of research and science behind its health benefits.

Ageing well after 40 isn’t about one big change; it’s a handful of small, steady habits.

If you want to keep it simple, the easiest way is to stay stocked with a properly high-phenolic oil. You can subscribe to both NOVEMBER and Masworth Family Groves, so they just turn up just when you need them, or have a read through the blog if you want to go a bit deeper before choosing.
