✨ Meet Mare'ka Jensen-Madison

Clinical Nutritionist • Herbalist • Founder, Hana Hou Juice Co.

As a functional nutrition specialist, my mission is to guide individuals back to balance—supporting the body’s innate capacity to heal, while allowing the immune system to operate at its full potential. Even in the face of autoimmune or chronic conditions, there are clinically-proven, root-cause strategies that work. With the right tools and guidance, the body often does what it was designed to do: restore, rebuild, and thrive.

I bring together the science of functional medicine with the wisdom of traditional healing. My background is rooted in evidence-based nutrition, clinical herbalism, and lab-informed care. I draw from bloodwork, stool and hormone testing, genetics, and digestive markers to uncover imbalances—and I work to correct them using personalized diet, therapeutic herbs, and targeted interventions.

After becoming a Reiki Master at 17, I began to feel the energetic impact of foods, people, and places. I earned my bachelor’s degree from the University of Hawai‘i and finished postgraduate training in Applied Clinical Nutrition through Northeastern University. While cooking for a husband-wife team of an acupuncturist and chiropractor, I studied Chinese Herbalism and witnessed firsthand the healing synergy between food and medicine. I later completed board certification as a Holistic Nutrition Consultant and a second board certification as a Naturopathic Practitioner. I was accepted into the Rupa Health Physician Program, which allows me to order and interpret advanced lab testing for clients.

In 2008, I opened L.A.’s first organic juice and herbal tonic bar on Ventura Blvd in Studio City. With Master Herbalist Dean Thomas of Shaman Shack running the bar, we facilitated 3- and 5-day detox cleanses for hundreds of clients across Los Angeles. People came through our doors daily with fatigue, inflammation, anxiety, and digestive issues. My simple questions were:
“How do you feel?” and “How do you want to feel?”
Those questions launched my lifelong devotion to studying with Taoist herbalists, superfood pioneers, clinical nutritionists, detox specialists, chefs, oncologists, and vitamin formulators. I learned that the answers were rarely one-size-fits-all—but when we listened closely and nourished wisely, people healed.

Today, that legacy continues through my private nutrition practice and my functional culinary company, Hana Hou Juice Co., here on Oʻahu. Each week, I handcraft nutrient-dense juices, broths, meals, and tonics based on my clients’ lab results, symptoms, and lifestyle needs. I support those navigating everything from autoimmunity and cancer recovery to adrenal fatigue, metabolic dysfunction, and advanced digestive conditions.

If you’re ready to explore a personalized approach to healing that blends ancestral wisdom with cutting-edge science, I’m here for you.

And if you’re on Oʻahu, I invite you to explore our local organic cold-pressed juices, functional meal plans, and anti-inflammatory cleanse programs, delivered straight to your door:
