We’re just entering that time of year again with all the sneezing, the sniffling, the blocked nose, the headaches, and for many, the frustration that comes with it.

Hay fever affects so many of us (between 10-30% to be exact), and every year it seems to catch people off guard. We look forward to summer for months, and then suddenly it hits, and you find yourself thinking - this is the only thing I don’t enjoy about this time of year!

Isn’t it interesting that so many people say their symptoms ease, or even disappear, when they go abroad? It really does make you wonder, is there more to it? And the answer - there absolutely is.

Because hay fever isn’t just about pollen, it’s about how your body responds to it. When you’re on holiday, you’re often less stressed, more relaxed, and naturally less inflamed. Your body isn’t sitting in that same reactive state, and that can have a real impact on how strongly you respond to things like pollen.

So What is Hay Rever Really?

Hay fever, also known as allergic rhinitis, is what we call an IgE mediated immune response. In simple terms, this means your immune system is mistakenly identifying something completely harmless like pollen as a threat.

When this happens, the body produces something called IgE antibodies, which attach to immune cells called mast cells. When you’re exposed again, these cells release inflammatory chemicals and that’s where your symptoms begin.

Most people have heard of histamine, and yes, it’s a big part of the picture. But it’s not causing the chaos alone. So, if you’ve ever though you can deal with the sneezing, but the congestion really gets to you, then this is why…

While histamine drives the more immediate symptoms like itching and sneezing, leukotrienes are responsible for the deeper, more stubborn symptoms, like:

• Nasal congestion
• Sinus pressure
• That heavy blocked feeling
• Increased airway sensitivity

These are inflammatory compounds released during the same immune response, and research shows they can increase swelling in the airways, mucus production, and overall inflammation.

They basically make it physically harder to breathe through your nose, which is why congestion can feel so intense and persistent. This is also why a purely antihistamine approach doesn’t always feel like enough, because there's so much more going on than just histamine, it’s a whole cascade of immune responses involving:

• Histamine
• Leukotrienes
• IgE antibodies
• And other inflammatory signals

There’s also another immune response behind it, known as a Th2 dominant response, which is often seen in allergic conditions, as well as asthma and eczema. What’s happening here is your immune system is a little more primed to react and leaning towards that allergic response, producing more IgE and inflammatory chemicals, which makes you more sensitive to things like pollen.

So this is the key thing to remember, It’s not the pollen itself causing the problem, it’s your body’s reaction to it. For some people, that reaction is mild and manageable. For others, it’s intense, draining, and can genuinely impact day to day life or completely ruin a weekend away in nature.

This is where things start to get really interesting, and sometimes a little confusing too, especially if your symptoms seem to change from year to year. That’s because your response to pollen is heavily influenced by your internal environment such as:

• Gut health: Around 70% of your immune system sits in the gut, so if your immune system is overreacting, the gut is always a really good place to look.
  
  The gut microbiome is essentially the collection of bacteria living in your digestive system, and it plays a huge role in how your immune system behaves. Research has shown that changes in this microbiome can influence how the body responds to allergens like pollen.
  
  There’s also the idea of gut permeability (leaky gut), where certain substances can pass into the bloodstream more easily, potentially triggering inflammation and immune responses.
  
  

• Histamine balance: Another question is how well is your body breaking down histamine? This is where the enzyme DAO (diamine oxidase) comes in, as its job is to help clear histamine from the body, and lower levels may be linked to more intense symptoms.
  
  Low histamine diets can sometimes help, but they’re restrictive and not always sustainable, so supporting the body’s ability to manage histamine is a bit more realistic.
  
  

• Inflammation levels: The more inflamed the body is, the stronger the reaction tends to be. Hay fever itself is part of a wider inflammatory response, and when that baseline level of inflammation is already higher, whether from diet, lifestyle, stress, or ongoing exposure to allergens, symptoms can feel much more intense.
  
  So if you’re more stressed, your nutrition isn’t quite as balanced, and life has just gotten a bit busy, this could be why one year you’re absolutely fine, and the next you’re hiding indoors!

• Stress: Stress is a big one as it has a direct impact on immune function and inflammatory processes, largely through its effect on something called the HPA axis, which helps regulate how the body responds to stress.
  
  When stress levels are higher, the body tends to be more reactive, and this can show up as more frequent or more intense hay fever symptoms. And this is where that ‘holiday effect’ comes in again, as so many people notice that their symptoms ease when they’re away and in a more relaxed, calm state.
  
  

• Nutrient status: Your overall nutrient status also makes a real difference. Nutrients like:
  
  - vitamin C
  - zinc
  - flavonoids (like quercetin)
  - vitamin D and vitamin E
  
  all play important roles in regulating the immune response and managing inflammation. So when the body is undernourished or lacking key micronutrients, it can shift into a more pro-inflammatory state, which may increase symptoms.

When you bring all of this together, it becomes clear that hay fever isn’t just about exposure to pollen. It’s about:

• how balanced your immune system is
• how inflamed the body is
• how well you process things like histamine
• and how supported your body is overall

Which is why two people can be exposed to the exact same pollen and have completely different experiences.

So What’s the Goal?

Rather than just trying to block symptoms with antihistamines, the aim is to support the body so it reacts less in the first place.

Our top nutrition tips for supporting symptoms:

• Bee pollen & Honey:
  
  Bee pollen and honey are really interesting options. The idea behind them is that small, regular exposure to pollen may help the body gradually build tolerance over time, a bit like a gentle form of desensitisation.
  
  They also naturally contain:
  - antioxidants
  - enzymes
  - small amounts of nutrients that support immune balance
  
  There are some small studies backing this. For example, one study using birch pollen honey found a noticeable reduction (around 60%) in symptom severity and a reduced need for antihistamines compared to controls.
  
  That said, this approach isn’t for everyone, and the research is still quite limited. So if you are going to try it, start very small and build up slowly, especially if your symptoms tend to be more severe.
  
  

• Omega 3 rich foods:
  
  Omega 3 fats are really important when it comes to inflammation. They’re found in foods like:
  
  - oily fish (salmon, mackerel, anchovies, herring and sardines)
  - walnuts
  - flaxseeds
  - chia seeds
  
  Diets rich in omega 3s such as the Mediterranean diet, are well known for their anti-inflammatory benefits, and there’s good evidence to show how they may help support allergic conditions. If struggling with including omega 3 rich foods, then look into taking an omega supplement instead.
  
  

• Plant rich diet:
  
  Fruits, vegetables, herbs, and whole plant foods are rich in antioxidants, flavonoids (like quercetin), vitamins such as C, D, and E, and they all help to:
  
  - reduce inflammation
  - support the immune system
  - and protect against oxidative stress
  
  You could also include things like spirulina, which is rich in antioxidants and has been studied for its anti-inflammatory and immune supportive effects, with some research even looking at how it can influence pathways involved in leukotrienes.
  
  There’s increasing evidence that diets rich in plant based compounds may help support allergic conditions, partly through their effect on both inflammation and the gut microbiome. It doesn’t need to be perfect, just aim to include a good variety regularly.
  
  

• A simple daily tonic
  
  If you like something easy and consistent to build into your routine, this is a lovely place to start.
  
  Warm water with:
  - fresh ginger
  - lemon
  - and a little local honey
  
  This combination is anti-inflammatory, soothing for any itchy throats and wonderful for the immune system.

Supplements can be incredibly helpful when it comes to hay fever, but it’s important to remember that no two people are the same and everyone’s immune system is different.

It’s also worth saying, these don’t tend to work like antihistamines, where you take something and feel instant relief within the hour. Instead, they work more gradually by helping the body become less reactive over time. Which is why they work best when used consistently, ideally before and during the season.

• A Vogel Luffa Complex:
  
  This is one of those products that works really nicely when symptoms are already there. It’s a blend of several herbs that all work slightly differently, which is why it’s quite effective for a lot of people.
  
  Why it works so well:
  
  - Luffa operculata (Luffa) → Traditionally used for sinus congestion to help ease that blocked, heavy, pressure feeling and reduce sneezing.
  - Galphimia glauca (Golden Thryallis) → One of the key herbs used in allergic rhinitis. Helps calm the immune system’s overreaction to pollen, rather than just masking symptoms.
  - Cardiospermum (heartseed) → Particularly helpful for inflamed mucous membranes like an irritated nose, throat, and even skin reactions.
  - Aralia racemosa (American spikenard) → Supports the respiratory system and helps with excess mucus and irritation in the airways.
  - Ammi visnaga (Toothpick Weed) → Traditionally used to support the airways and ease tightness, especially helpful if hay fever affects breathing.
  
  Overall, it works by calming inflammation, supporting the sinuses, and helping the body feel less reactive.
  
  

• Black Seed Oil:
  
  This one is a bit of a hidden gem for hay fever. It’s often talked about in relation to allergies, with some clinical studies showing that people with allergic conditions found a noticeable reduction in symptom severity when taking black seed oil regularly.
  
  Why it works:
  
  Black seed oil contains a compound called thymoquinone, which has strong anti-inflammatory and immune modulating effects. Rather than just blocking symptoms, it helps to calm the immune response itself, which can make reactions feel less intense over time.
  
  There’s also some evidence suggesting it can support respiratory health, which is perfect if your hay fever tends to affect your sinuses or breathing.

• Quercetin Complex:
  
  Quercetin is one of the most well known natural compounds when it comes to hay fever support. It’s a plant flavonoid found in foods like onions, apples, and tea, and it’s been studied quite a lot for its anti-allergic effects.
  
  Why it works:
  
  - Helps stabilise mast cells, meaning less histamine is released in the first place
  - Supports a more balanced immune response (including Th1/Th2 balance)
  - May help reduce inflammatory signalling linked to allergic reactions
  
  There’s also research suggesting it can help balance other inflammation pathways, including those linked to leukotrienes. This is why it can be so helpful not just for sneezing and itching, but also for symptoms like nasal irritation and sinus pressure.
  
  While on the topic of leukotrienes, you may have come across apple polyphenols, which are currently being looked at for their potential role in supporting these same inflammatory pathways.
  
  

• Vitamin D:
  
  Simple but actually really important. Vitamin D plays a key role in how the immune system behaves, particularly when it comes to allergic conditions.
  
  Why it works:
  
  - Helps regulate the immune system
  - Supports balance in that Th2 dominant response we talked about earlier
  - May reduce sensitivity to allergens when levels are optimal
  
  There’s quite a bit of research showing that lower vitamin D levels are associated with increased allergy risk and more severe symptoms. So while it’s not a quick fix, it’s a really important vitamin to keep topped up.

• Probiotics:
  
  This links back to what we spoke about earlier with gut health. Probiotics are beneficial bacteria that help support the gut microbiome, which in turn has a big influence on the immune system.
  
  Why they work:
  
  - help balance gut bacteria and support a healthier microbiome
  - support immune regulation, again supporting the Th2 response
  - may help reduce the severity of allergic responses by making the immune system less reactive
  
  Some studies have shown that specific probiotic strains can:
  
  - improve quality of life during allergy season
  - influence how the body responds to allergens
  - support a better balance between Th1 and Th2 immune responses
  
  They can be a really helpful supportive layer, particularly if gut health is a factor for you. Take daily, ideally at the same time each day and give it time, benefits are usually seen over weeks rather than days.
  
  

• Vitamin C:
  
  Vitamin C is one of those simple but really effective additions. You might have heard of people mega dosing vitamin C to get quick relief from hay fever symptoms, while this can sometimes help in the short term, the effect doesn’t tend to last very long. That’s because vitamin C is water soluble, so the body doesn’t store it very well, we literally use what we need and excrete the rest. So it’s better when taken consistently intake over time.
  
  Why it works:
  
  - powerful antioxidant that helps reduce oxidative stress
  - supports the immune system
  - helps the body break down histamine more effectively
  
  There’s also some suggestion that people with allergies may have lower levels of vitamin C, which could make symptoms feel more intense.
  

• Reishi mushroom:
  
  This is a really lovely option, especially if your symptoms feel a bit more systemic or stress linked. Reishi is what we call an adaptogen, which means it helps the body respond to stress in a more balanced way, and that includes the immune system.
  
  Why it works:
  
  - helps regulate the immune system (rather than overstimulating it)
  - supports balance in that Th2 dominant response we talked about earlier
  - has anti-inflammatory and immune modulating compounds
  
  It contains things like beta glucans, polysaccharides, and triterpenoids, which have been studied for their role in immune function, including reducing seasonal allergy symptoms.

• Helios Hayfever 30c Pillules
  
  These are a really lovely option if you prefer a gentler, more homeopathic approach.
  Rather than overriding symptoms, they work more gently with the body’s natural response, which is why many people find them easier to tolerate.
  
  Why they work:
  
  The blend is designed around the classic hay fever symptom picture, including:
  
  - sneezing
  - streaming eyes
  - irritation
  - sensitivity to pollen
  
  It contains:
  
  - Allium cepa → traditionally used for runny noses and watery eyes
  - Euphrasia → commonly used for itchy, irritated eyes
  - Sabadilla → often used for repetitive sneezing and pollen sensitivity
  
  They’re particularly popular for children, more sensitive individuals, or those who don’t tolerate stronger supplements very well
  
  And while responses can vary, we’ve seen them work really nicely alongside things like quercetin complexes and more anti-inflammatory support.

Other options to consider:

There are so many different options when it comes to hay fever. But what works really well for one person might not work in quite the same way for someone else.

So while the core supplements we’ve covered tend to work well for most people, there are a few other options worth taking a look at.

• Omega 3: We touched on this earlier, but for inflammation support, this is one of the key supplements to consider, especially if your diet is lacking in oily fish or healthy fats.
  
  

• Bromelain: An enzyme found in pineapple, which works well when inflammation and congestion are the main symptoms. It’s often used alongside quercetin, as it can enhance its effects, especially when it comes to nasal congestion and sinus pressure.

• A.Vogel Pollinosan Hayfever Eye Drops: If your symptoms are more eye focused, this is such an easy and effective option. It contains Euphrasia (eyebright), which is traditionally used for itchy, watery, irritated eyes.

• Organic Pharmacy Sneeze Away: And if you prefer something more herbal, this is a lovely option. It contains calming, anti-inflammatory herbs like chamomile, nettle and elderflower, and works by softening the body’s response rather than completely blocking symptoms which can feel much more manageable day to day.

Ok, so you may have read all of this and thought... I think I need all of those.

Because maybe your digestion feels off, your symptoms feel stress related, so reishi sounds great, maybe quercetin and vitamin C sound like the perfect combination and why not some black seed oil too. And before you know it, it starts to feel like you need seven different supplements just to get on top of your hay fever.

But, I'm happy to tell you that's not necessary. And this is one of the exact reasons why we created YourGut Defence.

Rather than buying lots of separate supplements, Defence was designed to bring many of these supportive nutrients together into one blend that works beautifully as an all rounder for:

• immune support
• stress
• inflammation
• gut health
• and overall resilience

It was literally created to help 'defend' the body, whether that’s from pollen, stress, illness, or just those periods where the immune system feels more reactive.

What makes it particularly interesting is that it contains several nutrients and compounds that support immune balance, especially around that Th2 dominant response we spoke about earlier.

Of course, when you take a blended formula, you’re not getting the same isolated doses as taking every nutrient individually. But when the ingredients genuinely complement each other well, which they do here, it can work brilliantly as a foundation.

Then you can build around it depending on your symptoms.

Maybe:

• you need extra vitamin D alongside it
• maybe Luffa feels like a great companion during active symptoms
• or perhaps you’d like to combine it with the Helios Hayfever Pillules for a gentler multi-layered approach

And please use us. Our team are incredibly knowledgeable, and we genuinely love helping people build the right little defence bundle based on their own symptoms and needs.

Ideally, with the right support, the goal is to bring the body back to a point of balance where hay fever becomes minimal, or even something you no longer struggle with. This isn’t about being perfect, and it’s definitely not about quick fixes. It’s about doing what’s sustainable, and supporting your body consistently enough that it can respond better over time.

Because in reality, the immune system takes time to rebalance, gut repair is gradual and inflammation doesn’t just disappear overnight. Which means what you do now, really does shape how your body responds next year.

If this is something you would like some more support with, then we offer Nutritional Therapy consultations which can be invaluable for the likes of managing allergies. Rather than just focusing on symptoms, our therapists look at the body as a whole, including gut health, immune balance, inflammation, nutrient status, and also offer a wide range of testing to get exact results.
