Mariel Nasis-Matuza, CPNP - Integrative Pediatrics Functional & integrative medicine www.integrativepediatricsli.com

I am a certified pediatric nurse practitioner (CPNP) specializing in integrative and functional medicine, looking for root causes of illnesses and always thinking “outside the box.” I care for children and their families all over the country, treating the whole child, not just the symptoms. Our goal is always to provide exceptional health care while also educating and empowering parents so they can be their child’s leading advocate, and developing and delivering evidence-based treatment plans using the most cutting-edge research. I have treated Autism Spectrum Disorders, PANS/PANDAS, allergies, and mitochondrial and metabolic disorders, among many others.

🌱 “You wouldn’t plant a seed in contaminated soil and expect it to grow. The same goes for conception.”

I wish I could coach more women before conception, because there is so much we can do to support fertility and reduce the risk of miscarriage when we prepare the body early.

Toxins play a major role in infertility and pregnancy loss. But most women are never told that.

Your body deserves to be supported, cleansed, and nourished before that seed is planted so it has the best possible chance to grow and thrive 💛

If you're thinking about starting or expanding your family, let’s talk. There are steps we can take now to help you feel confident and supported on your journey.

🎤 “I test, I don’t guess.”

Whether I’m working with kids or adults, I want real answers. That’s why I run labs to check for:
🩸 vitamin and mineral deficiencies
🧬 toxins, infections, and allergies
💩 and gut health (your second brain!)

If your gut isn’t working properly, your body can’t absorb what it needs to function. That’s where deeper issues can begin.

Let’s stop guessing and start understanding.

🎗️ September is Childhood Cancer Awareness Month.

To the families walking this path, my heart is with you.

To the children in treatment, in remission, and in memory, you are seen, loved, and never forgotten.

As a pediatric provider and a mother, I want you to know this:
We may not always have the right words. But we will always show up with compassion, support, and care.

💛 To the warriors, the survivors, the siblings, the parents, and the caregivers, you are incredible.
Your strength is unmatched. Your journey matters. You are not alone.

– Mariel

Today we reflect. We remember.

Visiting the 9/11 Memorial with my sons was powerful, emotional, and necessary, holding space with the thousands taken far too soon on that September morning.

And as we walked, those were not just names etched in stone. These were uncles, aunts, sons, daughters, fathers, mothers, family, friends, loved ones. Despite the loss and heartache that remains even 24 years later, somehow there is strength to keep going.

To all who lost loved ones, to the first responders, to the survivors, and to all who carry the weight of that day, we see you. We honor you. We will never forget.

September is National Childhood Obesity Awareness Month, and it’s not about blame. It’s about support, education, and prevention.

Obesity is not just about weight. It’s connected to gut health, nutrient absorption, hormone balance, inflammation, and emotional well-being.

As a pediatric provider, I look at the full picture.
I ask:
🥦 What are they eating?
🧠 How is their mood, focus, and energy?
💤 Are they sleeping well?
🦠 How is their gut absorbing nutrients?
💩 Are they pooping daily?

When we understand the why, we can create a plan that supports the whole child, physically and emotionally.

If you’re worried about your child’s weight, energy levels, or digestion, you’re not alone. There are answers and there is help.

Back-to-School just got easier with support from Mariel! 📚✏️

As the school year begins, Mariel is sharing her favorite tips to help your child stay healthy for their mind, body, and gut.
Here's a checklist to consider:

🍽️ Focus on nutrient-dense meals. Think healthy fats, protein, and colorful fruits & veggies
💧 Filter your water & go organic when possible. Minimize environmental toxins where you can
😴 Prioritize 9–11 hours of sleep per night. Rest supports immunity, behavior, and brain health
🌱 Support gut health. Limit sugar, load up on real food, and consider probiotics
🧠 Watch for mood, focus, or behavior shifts. These can be signs, not phases, so early support matters

📖🌍 Today is International Literacy Day! 🌍📖

Literacy is a powerful tool that transforms lives. It's not just for children—learning has no age limit. Whether it’s a child discovering the magic of books or an adult gaining confidence through reading and writing, education empowers people to dream bigger, do more, and live better.

💡 Lifelong learning opportunities are essential. Early childhood education lays the foundation, but the journey continues throughout our lives.

Let’s celebrate the power of literacy and commit to a world where everyone has the opportunity to learn, grow, and thrive—regardless of age or background.

📚 Because when we invest in literacy, we invest in stronger communities and brighter futures.

👇 Tell us: Who inspired your love of reading? Or share your favorite book that changed your life!

As a provider and a parent, I believe in informed consent, and that starts with having real, unbiased information you can trust. That’s why I’m excited to recommend "Vax Facts" by Dr. Paul Thomas and DeeDee Hoover.

It’s honest. It’s non-judgmental. And it gives families the clarity they need to navigate vaccine decisions confidently, at every age and stage. 📖
