Well… after avoiding it for far too long, I’ve finally updated my photo, a big deal as I really am not one to promote my ageing grey hair. 🫣😅

For those who are new here, I’m a Clinical Nutritionist, mum of two, and someone passionate about helping people better understand their health in a practical and realistic way.

I support babies, children, teenagers and adults with a focus on microbiome health, metabolic function, chronic fatigue, systemic inflammation and autoimmune conditions. My approach combines nutrition with functional and orthomolecular medicine to help explore possible root causes and support long-term wellbeing and healthy ageing (that includes grey hair).

Much of my passion for this work comes from my own health journey, and from supporting my children and loved ones through theirs. Seeing the impact that nutrition, lifestyle and targeted support can have on overall wellbeing is what continues to inspire me every day.

I aim to keep things practical, realistic and supportive — because health should feel achievable, not overwhelming.

This photo update is long overdue because honestly… I’d much rather talk about gut health than posing for the camera. 😂👍🙃

I am pleased to finally see a name change for this condition, which I was personally diagnosed with in my 20s. The updated name makes WAY more sense to me!

From my own experience, the metabolic reference is key. Polyendocrine Metabolic Ovarian Syndrome (PMOS) helps shift the focus toward the metabolic and hormonal disruptions that are often driving symptoms, rather than focusing only on ovarian cysts.

When I was diagnosed about 25 years ago, the attention was almost entirely on the cystic appearance of the ovaries, along with irregular cycles, and not the metabolic consequences that came with it. At the time, I had already been identified as pre-diabetic, yet this was largely disregarded as unrelated to the condition. Over the years, through my own perseverance and deeper learning, (and ultimately training to become a clinical nutritionist!!) I came to understand just how significant metabolic dysfunction can be in the overall symptom picture of what was then called PCOS.

I am hopeful that the shift to PMOS will help support women in better understanding the broader aspects of the condition, including blood sugar irregularities, inflammation, body composition and muscle mass goals, skin concerns, hirsutism, and overall hormonal imbalance.

I also hope this change encourages more comprehensive annual lab testing, helping women gain greater clarity around why lifestyle factors such as nutrition, movement, sleep, and stress management can play such an important role in supporting long-term health outcomes.

A name change alone will not change everything, but it may encourage earlier support, deeper investigation, and more personalised care for women navigating this condition.

Along with my own journey, I have helped many women on their own PMOS journey, to learn and understand their specific drivers. If you want to know more, make sure to reach out ! 👍🤓

Wow. PCOS finally has a new name. After years of debate, the consensus has landed on PMOS for polyendocrine metabolic ovarian syndrome.

The name change was needed because the so-called "cysts" of "polycystic" are not actual cysts, but really just follicles or eggs, which are normal for the o***y.

What are your thoughts on the new name? As Dr Fiona McCulloch ND points out, it does sound a bit too similar to PMS.

I couldn’t agree more with the comment about the importance of understanding a patient’s markers for B12, for cognitive decline.

And the fact that this is no longer a funded blood test in NZ – unless you meet certain criteria – blows my mind.

B12 is such an important nutrient to consider for brain function in all population. And we just don’t consume enough from our diet. Let’s be honest, here in NZ the majority do not eat organ meat, shellfish or enough seafood, DAILY, to have optimal B12 intake.

Also, I love the statement “this does not mean everyone should start taking high dose supplement…..” this is certainly true! Understanding a person’s methylation is fundamental in knowing if B12 is even the issue, it could be another B vitamin or other nutrient altogether, that is needed. Even working out which type of B12 should be taken.

And the serum B12 test reference is so wide, it is important to understand if we are actually dealing with a true B12 deficiency, in the context of presenting symptoms.

So yes, I feel we need to bring back funded B12 testing, and to understand where on the reference range someone falls in the context of risk for dementia, but also for children and teenage brain health.

But we should also be considering methylation as part of this picture and this is where I tend to ask patients to consider Active B12 and methylmalonic Acid, plus nutrigenomic testing.

We may have misunderstood vitamin B12 — and the brain could be paying the price.

A new study led by researchers at the University of California, San Francisco suggests that older adults with vitamin B12 levels considered “normal” may still show signs of subtle neurological decline.

The research focused on 231 healthy older adults with no dementia or mild cognitive impairment. Even though their average B12 levels were well above the current U.S. deficiency cutoff, those with lower levels of active B12 — the form the body can actually use — performed worse on tests of thinking speed and visual response.

The most concerning finding came from brain scans. MRI results showed that people with lower active B12 had more white matter lesions, a type of brain change linked to cognitive decline, dementia, and stroke risk. White matter acts like the brain’s communication network, helping different regions send signals to each other quickly and efficiently.

Researchers say this raises an important question: are current B12 deficiency cutoffs too low to protect brain health, especially in older adults?

Vitamin B12 is essential for making red blood cells, supporting DNA production, and maintaining healthy nerves. But this study suggests that simply being “not deficient” on a lab report may not always mean the brain is getting enough.

The researchers believe future guidelines may need to look beyond total B12 levels and include functional biomarkers that better reflect how much B12 is actually available to the nervous system.

This does not mean everyone should start taking high-dose supplements without medical advice. But it does highlight the need for better testing, earlier detection, and more attention to B12 status in older adults with memory, nerve, or thinking-speed concerns.

Celery: the crunchy green stick everyone forgets about… until your digestion says thank you!

As a kid, I hated when my mum would pop these “palos” in my lunch box (Spanish for sticks). On the days these were in my lunch box, I could sense she had reached her limit for lunch inspiration! 😅 😅

But now of course, I have a much deeper appreciation for the humble celery stick. !!

While celery probably does not give off glamourous Pinterest image vibes, it does quietly bring some impressive nutrition to the table. It contains vitamin K for bone and blood health, vitamin C for immune support, folate, potassium, and small amounts of antioxidants that help support overall health. And most importantly the fibre content can help keep digestion moving and support a healthy gut microbiome.

And let’s not forget hydration — celery has a great amount of water, making it a great snack for busy days when your coffee intake is suspiciously higher than your water intake 👀☕️

We are at the start of celery season, so here are some easy ways to use these “sticks”:

>Dip into hummus or nut butter
>Toss into soups, stir fries, or stews/casseroles
>Chop into salads for crunch
>Fill with cream cheese

Celery may not be glamorous, but neither is a healthy bowel motion… and both deserve more appreciation 😅👍🤓

Why jumping into methyl B9 is not always the golden answer!!!

Methylated B9, often referred to as methyl-folate, is often seen as the “go-to” supplement for supporting energy, mood, detoxification and overall methylation pathways. But in clinical practice, jumping straight to high dose methylfolate does not always work well for everyone.

Methylation is a TOTAL BIOCHEMISTRY process, NOT JUST a folate process. I like to refer to it as highway, at risk of bottle necks or traffic jams.

For methylfolate to be used well, the body also relies on enough vitamin B12, B6, B3, zinc, magnesium and choline. If these nutrients are low, adding methylfolate alone can sometimes leave people feeling overstimulated, anxious, irritable, wired, headachy or fatigued instead of better.

This can be especially relevant in people with variations in COMT and MAO genes, as these pathways are involved in processing neurotransmitters such as dopamine, adrenaline and serotonin. Some people may simply be more sensitive to rapid shifts in methylation and nervous system activity.

Supporting the foundations first — including digestion/microbiome, protein intake, mineral status and nervous system support — is often a gentler and more effective approach than starting with large amounts of methylated nutrients straight away.

Bioindividuality matters. Genetics, environment and nourishment need to be considered on an individual basis.

Because what works well for one person may not feel right for another.

We started off with the basics. Just some strain specific probiotics and mineral supplementation to support her chronic cough, which was affecting her in more ways than one. Repeated endoscopies showed some inflammation, but with no firm plan on how to improve this, she was stuck with the same symptoms.

The first feedback came back as “ Regarding my cough, thank you for making me feel better, even just 30% , that’s a great start! None of the doctors achieved that in years. I'm looking forward the stool results and hopefully know more about what else is going on”

She was ready to dig in deeper. She knew there was more to her symptoms than what the repeated endoscopy results were coming back with. We both knew that the clue was in how she felt a benefit from being on antibiotics. Short term gains, but long-term consequence. So she went ahead with stool analysis.

Sure enough, there was plenty of data there to move on with. Factors that helped to explain her low energy and digestive complaints. The second feedback came back as “I’m feeling slightly better overall, less congested , more energy. I hope with the next round of treatment, I will be feeling even better!”

Small wins! Enough for her to finally notice a positive change overall.

Loving the client feedback! 👍🤓

I am having an overgrowth of parsley in my herb garden this year, but I am not complaining! Parsley is one of those super versatile herbs which can be added to almost any dish, or used as part of homemade dressings.

Parsley is a highly functional food, maybe you want to call it a super food, that can support multiple genetic pathways, particularly those involved in detoxification, inflammation, and methylation.

Super rich in flavonoids such as apigenin and luteolin, parsley can provide strong antioxidant support for genes like GSTM1, GSTM3, and NQO1, which are involved in phase II liver detoxification.

Individuals with reduced function in these genes may benefit from parsley’s ability to enhance glutathione activity and reduce oxidative stress. It is also naturally high in chlorophyll, which will further supports toxin binding and elimination. It is my go-to recommendation for a food as medicine approach to supporting detoxification.

Parsley is also a valuable source of folate, making it beneficial for individuals with variations in methylation-related genes such as MTHFR, MTR, and MTHFD1. While it does not replace targeted supplementation, including parsley regularly can contribute to overall methylation support, which is important for DNA repair, neurotransmitter balance, and energy production.
For inflammatory gene variants such as IL6, TNF-α, and IL1β, parsley offers anti-inflammatory effects through its polyphenol content. These compounds help modulate inflammatory pathways, potentially reducing chronic low-grade inflammation often seen in individuals with these SNPs (DNA variants).

Parsley also contains vitamin C and other antioxidants that support genes like SOD2 (MnSOD) and CAT, which are responsible for managing oxidative stress at the mitochondrial level. This makes it particularly useful for supporting energy production and reducing cellular damage.

As you can see, parsley is a simple yet powerful addition to a nutrigenomic-focused diet, offering broad-spectrum support across detoxification, methylation, inflammation, and oxidative stress pathways.

Not only supporting DNA data, parsley is a nutrient-dense herb that can support a healthy microbiome. It contains polyphenols and flavonoids, which act as prebiotics by feeding beneficial gut bacteria and encouraging microbial diversity. Parsley is also rich in vitamin C and chlorophyll, both of which may help reduce oxidative stress and support a balanced gut environment. Its mild antimicrobial properties can help inhibit the growth of less desirable bacteria without disrupting beneficial strains.

Parsley may also aid digestion by stimulating gastric juices, helping to improve nutrient breakdown and absorption—key factors in maintaining overall gut health and microbiome resilience.

Simple ways to add parsley to your diet:

>Add it to fresh salads

>Make a gremolata or chimichurri type dressing – lemon juice and zest, Olive oil, parsley, garlic, (chilli if you like)

>Add to a dish of freshly roasted root vegetables along with garlic, and home made mayo

>Make a “green’s” smoothie, using plain or vanilla protein powder, cucumber, pineapple ginger and parsley with coconut water
🤤👍😍
