At the end of each year I like to pause—really pause—and listen. Not to the noise of resolutions or the pressure of reinvention, but to the quiet signals my body and the natural world offer. After all, our health journeys aren’t linear checklists. They’re ecosystems of small decisions, shifting seasons, setbacks, curiosity, and grace.
And in 2025, as our understanding of the microbiome continues to expand, I find myself returning again and again to one question:
What is your gut trying to tell you?
Listening to the Inner Terrain
When I first stepped into microbiome science nearly two decades ago, it was out of necessity. I was looking for answers to support my husband’s health, and the conventional path left so many pieces unexplored. The gut—this vast, ancient community of bacteria, fungi, viruses, and metabolites—became my teachers.
What struck me then, and still amazes me now, is how much the gut mirrors the natural world. Diversity creates resilience. Cooperation is more powerful than competition. Balance isn’t a fixed point—it’s a relationship we recalibrate every day.
If your health journey this year felt messy or unfinished, you’re not alone. That’s the nature of ecosystems. They adapt. They recover. They surprise us.

The Small Signals That Matter
Many people think gut health shifts only show up as digestive changes. But the gut is a storyteller with a wide vocabulary. It speaks in:
- Energy levels
- Sleep quality
- Mental clarity
- Stress resilience
- Immune patterns
- Even the steadiness of your mood
Our modern environment pulls constantly on this system—whether through stress, travel, low-nutrient diets, or the countless chemical exposures in our soil, water, and food. That’s why reflection is so valuable. When we slow down, we start to recognize the connections that were there all along.
What have you noticed this year?
Maybe you noticed how your digestion changed during a stressful season.
Maybe you felt more grounded when you prioritized fiber-rich foods.
Maybe a daily walk softened the tension you didn’t realize you were holding.
These insights are guideposts, gently pointing you toward what your internal terrain needs next.
Returning to Balance Through Community—Inside and Out
One of the ideas that continues to inspire me is that our bodies are not machines to be fixed; they are communities to be supported. Every time we nourish our microbiome—with whole foods, targeted probiotics, movement, sunlight, or rest—we're essentially tending the soil.
And just like in nature, you don’t need perfection to grow something meaningful. You only need consistency and curiosity.
I’ve always believed that healing happens in community. That includes the microscopic guilds of bacteria working together in your gut, and the people walking alongside you—family, friends, practitioners, and the wider wellness community seeking more natural, sustainable ways to support their health.

A Gentle Invitation for 2026
As you look toward the new year, consider taking a moment to reflect on your gut health journey:
- What supported your balance over the last year?
- What challenged it?
- What small shifts are you ready to explore in the new year?
Not from a place of pressure, but from a place of partnership with your own body.
Your microbiome is incredibly adaptive. It wants to support you. And the more you understand its rhythms, the more empowered you become to support your health in ways that feel aligned and sustainable.
Walking Forward With Intention
If there’s one thing experience has taught me, it’s that the body is always trying to move toward balance. When we give it the right conditions—nutrient-dense foods, supportive microbes, less toxic load, a little more rest—it often responds more gracefully than we expect.
So as we leave behind 2025 and 2026 unfolds, I invite you to stay curious. Stay compassionate with yourself. Keep learning, keep listening, and keep nurturing the inner ecosystem that shapes so much of your well-being.
And as always, discuss any new steps with a trusted health professional who can support your personal path.
Here’s to another year of cultivating resilience—from the inside out.

the reach of science and BiotiQuest, the first of it’s kind probiotic line. Since John’s diagnosis in 2002,
Martha began learning the science of agriculture, nutrition, environment, infectious disease, Parkinson’s
pathology and much more. In 2014, when the first research was published showing a connection between the gut
bacteria and the two phenotypes of Parkinson’s, Martha quit her former career as a business turnaround expert
and founded The BioCollective to accelerate the discovery of the impact of gut health on all human disease. Martha was a speaker at the White House 2016 Microbiome Initiative launch, challenging the scientific
community to “think in a broader context”. Her systems thinking background and experience has led to collaborations
across the scientific spectrum from neuroscience to engineering to infectious disease. She is a respected out of the
box problem solver in the microbiome field and brings a unique perspective to helping others understand the
connections from the soil to the food to our guts and our brains.
