Rupali is a holistic health practitioner who knows there are no magic pills or 'one-size-fits-all' solutions in healthcare. A registered New Zealand pharmacist, she runs her virtual clinic, Pause.Breathe.Live, focusing on Functional Nutritional Therapy. Specializing in gut health, she offers functional testing to guide clients toward true healing.
You’re eating clean. You’ve tried keto, paleo, maybe even intermittent fasting. You’ve taken the supplements someone recommended on Instagram. And yet you still feel bloated, exhausted, or anxious. You’re not alone, and you’re not broken. You may simply be missing the one piece that changes everything: a functional approach.
As a pharmacist also trained in functional nutritional therapy, I often work with people who have “tried everything”. They’ve bounced from GP to specialist, from dietitian to naturopath, and they still don’t feel well. That’s where functional nutrition comes in. It’s not just another diet plan or supplement protocol. It’s a different philosophy altogether, one that puts you at the centre of your healing.
1. It’s root-cause focused, not symptom-obsessed
Traditional approaches often work like this:
Symptom → Diagnosis → Prescription.
If you’re tired, you might get iron tablets; if you’re constipated, a laxative. If you’re anxious, a referral to mental health services. But what if your fatigue isn’t about iron at all, but about gut dysfunction? Or is your anxiety connected to blood sugar crashes?
Functional nutrition zooms out. We ask: Why is this symptom happening in the first place? We look for the root cause- whether it’s nutrient depletion, digestive dysfunction, chronic inflammation, toxic burden, or hidden infections. We’re not just managing the problem. We’re investigating it.

2. It’s individualized, not one-size-fits-all
There is no universal “perfect” diet. And yet most conventional advice is still prescriptive: “Eat less sugar”, “cut carbs”, “follow the food pyramid”. But every person has a unique story, with different genetics, gut health, stress levels and triggers. In functional nutrition, we don’t just ask what you eat, we ask how you digest, why you crave and what your body is trying to tell you.
That’s why two people with the same diagnosis (say, Irritable Bowel Syndrome or IBS) might receive completely different plans. Your “stress bucket” is different from anyone else’s, and so is your healing path.
3. It respects the gut-brain-body connection with functional nutrition
We’re traditionally trained to treat systems in isolation: the digestive system, the nervous system, the reproductive system. But your body doesn’t work in silos and neither should your care.
A client’s anxiety may not start in the mind, it may begin in the gut, where inflammation and microbial imbalance send distress signals to the brain. Hormonal issues often stem from blood sugar swings or liver sluggishness. Functional nutrition sees these connections and works across systems to support the body’s innate ability to regulate and repair.

4. It uses testing to guide, not guesswork to mask
Rather than guessing what might be wrong or throwing supplements at symptoms, functional nutrition uses functional lab testing (such as GI MAP, hormone panels and blood chemistry) to clarify what’s actually happening inside. This removes the guesswork and helps us take action with clarity.
Conventional blood tests may show you’re “in range,” but functional testing helps us understand if you're actually thriving.
5. It’s collaborative and empowering
Instead of handing over a meal plan and a supplement stack, I walk alongside my clients. We review test results together. We discuss cravings, poop patterns, fatigue and life stressors. I teach people how to understand their body’s signals and that includes learning how their digestive system reflects their overall health.
It’s not about following rules. It’s about rebuilding trust, with your body and with your health.
You can learn more about how I bridge conventional medicine and holistic care in my Brainz Magazine interview.
In summary
Functional nutrition doesn’t promise quick fixes, because real healing takes time. It asks deeper questions. It looks beyond the surface. And it empowers you to understand your body rather than fear it.
If your symptoms haven’t gone away despite your best efforts, maybe the next step isn’t more willpower or another trend. Maybe it’s a more compassionate, personalised and functional approach.
