Welcome
Hi, I’m Jaclyn, a clinical nutritionist specializing in gut health, inflammation reduction, and metabolic imbalances. I take a root-cause approach using comprehensive lab testing, health history, and personalized protocols to uncover what's driving symptoms like fatigue, bloating, anxiety, and weight gain.
With a unique focus on how nutrition supports mental health, mood, and stress, I guide clients toward sustainable energy, better digestion, and whole-body balance.
My practice is grounded in fiber-forward, whole-food nutrition, habit-building, and science-backed strategies, including anti-inflammatory protocols, lifestyle integration, bloodwork analysis, and advanced nutrigenomic testing.
To provide a clear path forward, I developed the Essential Core4 Framework—a structured approach built around four key pillars: inflammation, metabolism, hormones, and gut–immune health.
This method helps uncover the root causes of imbalance and guides the creation of targeted, evidence-based solutions that go beyond surface-level fixes.
While my approach centers around fiber-focused, nutrient-dense eating, I meet clients wherever they are, helping them build sustainable habits that align with their lifestyle and goals.

Are You Ready?
Here’s the thing: this is your one life. And while we all move at our own pace, staying stuck doesn’t serve us.
Every small step forward is a step toward better health, more energy, and a life that feels lighter, clearer, and more aligned.
The truth is, time doesn’t wait. There’s no time machine when we’re sick, tired, or overwhelmed. But the good news? You don’t have to do it alone.
If you're seeking more energy, less bloating, sustainable weight loss, glowing skin, better mood, and a real-life approach to healthy eating, then yes, you’re ready.
But maybe you're thinking:
“I’m constantly bloated, inflamed, and exhausted, and I don’t know what’s causing it.”
“My hormones feel out of balance, my energy, weight, mood, or sleep just aren’t what they used to be.”
“Every time I try to eat better, I end up overwhelmed, confused, or back where I started.”
“I’ve seen doctors, done tests, but no one has helped me figure out what’s really going on.”
I want a sustainable way to eat for energy, weight, and long-term health without extremes or obsession.”
Take a breath, I’ve got you.
The Essential Core4 Framework
Most programs only scratch the surface. My Essential Core4 Framework goes deeper, helping me uncover why you’re feeling bloated, tired, stressed, or stuck. By assessing these four key pillars, I create a clear, step-by-step plan to restore balance and get you feeling like yourself again.
1. Inflammation & Oxidative Stress
Hidden inflammation can show up as joint pain, skin flare-ups, brain fog, or fatigue. I look at how your body is handling stress, toxins, and everyday exposures and support your natural detox and antioxidant systems so your body can calm inflammation and heal.
2. Nutrient Deficiencies & Metabolic Health
Energy crashes, cravings, and stalled weight loss often trace back to nutrient gaps and blood sugar imbalance. I assess your vitamin and mineral status, digestion, and how your body uses energy, then create a plan that restores balance with the right foods, supplements, and lifestyle strategies.
3. Hormonal Balance
Hormones control everything from mood and sleep to weight and metabolism. Whether it’s thyroid issues, adrenal stress, or shifts in perimenopause or menopause, I look at the full picture and guide you in balancing your hormones naturally, so your body feels stable and supported again.
4. Gut & Immune Health
Your gut is central to your digestion, energy, and even your immune system. I help uncover hidden imbalances like food sensitivities, bloating, or microbiome diversity issues, and rebuild gut integrity so you can finally feel comfortable, energized, and resilient.
