Meet tenna
The Visionary Behind Longevity Lab
Tenna is a wellness innovator and advocate for detoxification, vitality, and deep transformation.
With over 15 years of experience, she blends grounded expertise with a forward-thinking approach to health. Her journey has included launching functional food and drink brands, co-founding Purearth and Triveda life, and becoming a quiet thought leader - driven by results, not recognition.
Her studies with pioneers like Gabriel Cousens M.D. and David Wolfe laid the foundation for a unique methodology that fuses ancient wisdom with modern science.
What began with a life-changing spiritual cleanse in Bali in 2009 became a lifelong devotion to cellular healing - from enzyme therapy, peptides and herbal protocols to breath work, handstands and fermented nutrition.
Today, based in Ibiza, Tenna leads Longevity Lab - a culmination of her work - offering advanced detox programs and functional formulations to support the body’s natural intelligence.
Ibiza is aligned with elemental healing.
“The future of healing is rooted in detoxification - and it’s more needed than ever.” – Tenna x

Cleansing isn’t a trend—it’s a return to wisdom. For Tenna, it’s a lifelong calling. Every offering is created with attention, integrity, and care.
With over 15 years of experience in detoxification, gut health, and integrative nutrition, she has supported thousands through tailored programs in the U.K. and guided transformational retreats around the world. “The healing happens when people choose to commit to themselves.”
In 2012, Tenna founded Purearth, one of the U.K.’s pioneering companies in bespoke detox programmes and gut health. What began as a kitchen project grew into an award-winning business that helped shape the clean-label movement, creating acclaimed functional food and drinks for the global market, alongside innovative cleansing protocols.
Her studies with Gabriel Cousens M.D. and David “Avocado” Wolfe deepened her knowledge of raw food nutrition, botanical medicine, and holistic healing—teachings she weaves into her own journey of self-healing and empowerment.
Blending ancient traditions with science-backed practices, Tenna’s approach is guided by nature, intuition, and results. Her programmes address everything from hormonal balance and liver health to fertility, postnatal vitality, and long-term regeneration of the body from the inside out.
Now based in Ibiza with her two children, Otto and Izabelle, Tenna continues to support clients worldwide. She specialises in:
Seasonal juice fasting & enzyme cleansing (including mucoid plaque release)
Liver, parasite, and heavy-metal detoxification
Hormonal balance (pre-menopause & menopause support)
Fertility, trimester & new-mum vitality
Gut health, longevity & vitality programmes
“I don’t believe in fixing—we create space for the body to remember its brilliance. All I ask from my clients is active participation and a commitment to growth.”

Mariel Witmore
-
Mariel’s journey into holistic wellness began from a place many will recognise, burnout, disconnection, and a body sending loud signals that it was time to change. After walking away from a high-performance career and quitting ADHD medication cold turkey, her body began to unravel - eventually revealing a series of complex diagnoses: Hashimoto’s thyroiditis, a 3cm hiatal hernia, gastritis, and excessive bile buildup.
But what came next was nothing short of transformation. Choosing to take her healing into her own hands, Mariel began to study movement, nourishment, and the deeper relationship between emotion and health.
She uses her lived experience to guide others toward balance, agency, and inner peace. Her sessions are intuitive and empowering, weaving breath, movement, and grounded wisdom to support those navigating physical symptoms, life transitions, or emotional overwhelm.
“Mariel brings raw honesty, gentleness, and real-life strength to her work. She’s walked the path—and she guides others with deep compassion.” - Tenna x
