Doctors’ 10 health predictions for 2025

In 2024, we saw more people than ever prioritising their long-term health. The demand for tests like our Ultimate Performance and Optimal Health Blood Tests spiked, reflecting this shift. Beyond blood testing, we also saw artificial intelligence (AI), particularly ChatGPT, make waves globally — reminding us of the information overload world we live in (and the need to fact-check what we read!).

But what about 2025? We asked our team of doctors to share the key trends and innovations bubbling beneath the surface.

Here are the topics they predict to make a surge over the next 12 months:

• Food and gut health
• Wellness retreats
• Pleasure and comfort
• Advancements in healthtech and testing

1. We'll wage war on ultra-processed foods and toxins

The convenience of modern life has come with a cost: we’re over-consuming, over-informed, and often overwhelmed. While it’s easy to have whatever we want delivered to our door, the downside is that many of these products, particularly ultra-processed foods, harm our health.

In 2025, we predict a clear shift toward cleaner eating. People are becoming savvier—reading ingredient lists instead of relying on marketing claims. And as awareness grows, so will the demand for transparency from brands.

For those wanting to get started, apps like Yuka are game-changers. Yuka scans labels on food and cosmetics to tell you if they’re good for you. Importantly, it’s independent of any brands or food companies, ensuring unbiased insights.

At the same time, we’re becoming more mindful of the toxins in cheap plastics and everyday products. There are many harmful effects of toxins to be aware of, including the oestrogenic effects of BPA. Thankfully, we predict that these materials, often laced with hormone-disrupting chemicals, will be phased out in favour of sustainable, non-toxic alternatives.

5 environmentally friendly swaps to consider*:

1. Cleaning supplies - try Purdy & Figg or Kit & Kin
2. Food containers - glass containers, like these from Amazon
3. Cookware - explore Cast Iron pans
4. Toilet rolls - Who Gives a Crap
5. Deodorant - Fussy or the Natural Deodorant Company

This movement isn’t just about health—it’s about the planet too. *We don't have any affiliates here; it's just our own research.

2. AI will deliver personalised nutrition

AI has already changed how most of us work and communicate, but its potential in healthcare is only just being realised. In 2025, we’ll see AI revolutionise how we approach nutrition.

The demand for gut microbiome testing has surged over the past five years, with search interest increasing by approximately 400% [1]. These tests provide valuable insights into our unique gut health, but the next step is pairing them with AI.

Imagine an app that analyses your gut microbiome results, preferences, and goals to create personalised meal plans, shopping lists, and even recipes. Over time, the AI learns what works for your body, adjusting recommendations to optimise your health.

3. Functional foods will become our medicine

As ultra-processed foods fall out of favour, functional foods will take centre stage. These nutrient-dense foods provide specific health benefits, such as reducing inflammation, boosting immunity, or enhancing cognitive function.

In 2025, expect to see an even bigger boom in adaptogenic mushrooms like lion’s mane (for focus and memory), reishi (for stress relief), and chaga (for immunity). CBD will also continue its rise, with more people exploring its therapeutic potential for everything from pain relief to sleep support.

Functional foods aren’t just a trend — they’re a step toward viewing food as medicine.

4. Holidays will be digital-free

In an age of constant connectivity, digital detox retreats will offer a much-needed escape. These holidays, designed to help us unplug from our devices, are gaining popularity as people recognise the toll of digital fatigue.

Doomscrolling, binge-watching, and endless notifications trick us into thinking we’re relaxing when we’re actually overstimulated. Digital detox retreats aim to break that cycle, offering rest and reconnection in a screen-free environment.

Will 2025 be the year we embrace more screen-free moments in our everyday lives too? If you like the sound of that, have a look at Unplugged or Unyoked.

5. Can we get a woo-woo?

Practices like yoga, meditation, breathwork, and sound baths have long been part of other cultures, but they’re gaining traction in the UK as we seek deeper relaxation and stress relief.

What’s driving this shift? Part of it is celebrity influence — Madonna and Kim Kardashian have both shared their love of sound baths — but it’s also a reflection of our need to unplug and recharge.

These practices may still seem “woo-woo” to some, but their benefits are backed by research. Yoga, for example, has been shown to reduce cortisol levels, while sound therapy can promote deep relaxation.

Ecstatic dance is another one that’s creeping into festivals. Google Trend graphs are also showing an increase in popularity. Time to make some moves?

6. Healthy ageing takes centre stage

The pursuit of healthy ageing is gaining momentum, and 2025 is set to bring even more advancements in this area. Supplements like Nicotinamide mononucleotide (NMN) [2], which support cellular health, and omega-3 fatty acids are drawing attention for their potential to boost longevity and well-being.

The brain, as our most complex and vital organ, is a key focus in this journey. Research shows that omega-3 supplements can improve blood markers. There is also evidence they may help protect against brain degeneration in older adults [3]. 

Similarly, NMN is gaining attention for its ability to boost levels of NAD, a molecule essential for energy production and cellular repair. Animal studies have shown promising results, suggesting NMN may improve both lifespan and healthspan.

Recent human trials also offer encouraging findings. In a 60-day study of 80 healthy middle-aged adults, NMN supplementation significantly increased blood NAD levels, improved physical performance (measured by walking distance), and maintained biological age compared to placebo. The benefits were most pronounced at a daily dose of 600 mg, with no reported safety concerns or adverse effects.

While these results are promising, more research is needed to confirm the long-term benefits of NMN for human health and establish optimal dosing guidelines. In addition to supplements, advancements in areas like hormone therapy and novel cholesterol-lowering medications are helping people age not just longer, but better. The goal isn’t simply to add years to life — it’s to make those years vibrant, active, and fulfilling.

The focus isn’t just on living longer — it’s on living well.

7. More pleasure to the people

The stigma around once-taboo topics like hormonal changes from menopause or low testosterone is fading. Discussions about sexual health are becoming more open. And people are more open to fixing the problem, rather than just accepting the symptoms as part of getting older.

Next year, we predict more people will openly explore treatments that bring pleasure back into their lives: mentally, physically, and sexually. We'll see men and women seeking to enhance their libido and overall sexual wellness as part of taking care of overall wellbeing. 

In 2025, expect continued innovation in this area, from therapies that address hormonal imbalances to treatments that support emotional and physical intimacy.

8. Advancements in wearable health technology

Wearable devices have come a long way, and their impact on healthcare is only growing. Most of us are already familiar with wearable tech — be it a smartwatch, fitness tracker, or sleep monitor. But in 2025, these devices will reach new levels of sophistication, offering even more possibilities for real-time health monitoring and remote care.

From tracking heart rhythms and glucose levels to monitoring sleep and stress, wearables are empowering people to take control of their health like never before. These devices are also becoming increasingly integrated with healthcare systems, paving the way for more effective preventative care. Innovations like the Flow Neuroscience headset are even enabling at-home treatments for mental health support, while apps synced to wearable devices provide personalised guidance and insights.

It’s not just traditional healthcare seeing these advancements — wearables are making waves in the beauty world, too. From light-therapy masks promising to detox your skin to gadgets claiming to deliver pain-free facelifts or muscle recovery, beauty tech is rapidly evolving. While some of these lofty claims may prove to be just trends, time and research will determine whether they’re truly effective or simply passing fads.

9. Testing for personalised care

Testing is no longer a luxury—it’s a cornerstone of personalised healthcare. From analysing genetics and blood biomarkers to stool, urine, and even hair follicles, testing has become an accessible and standardised approach to understanding individual health needs.

In 2025, we will see a bigger focus on genetic testing. It will play a key role in improving personalised care.

By looking at a person's genes, healthcare providers can better predict disease risks. They can also customise treatments to fit each person's genetic profile. Additionally, they can suggest lifestyle changes to improve long-term health.

Genetic tests can help people understand their predisposition to:

• Heart disease

• Diabetes

• Certain cancers 

This level of insight opens doors to preventive care, allowing doctors to identify and address potential health concerns before they become serious issues.

Beyond disease prevention, genetic testing can change the way we approach fitness and nutrition. Some tests can reveal how your body metabolises certain nutrients, which types of exercise suit you best, or even how you respond to stress. Imagine being able to create a completely personalised health plan based on your DNA.

10. Preventative care goes mainstream

As awareness of chronic conditions like diabetes and heart disease grows, so does the emphasis on prevention. In 2025, preventative care will take centre stage, with more people opting for regular health checks to catch potential issues early.

As we’ve already explored, advancements in wearable health tech and AI are making it easier to track key health metrics in real-time. However, perhaps one of the most critical tools in this preventative care shift will be blood testing.

Blood tests can offer a wealth of valuable insights into your health. They can highlight early indicators of chronic disease, helping you reduce the risk of developing them. 

These include nutrient deficiencies, hormone imbalances, cholesterol levels, and blood sugar regulation. They can also spot early signs of diseases like diabetes and heart problems.
