Meet Tenna

The Visionary Behind Longevity Lab

Tenna is a wellness innovator, and a passionate advocate for detoxification, vitality, and transformation. With over 15 years of experience in the health and wellness space, she has a strong track record of bringing successful functional foods and beverages to market. With an extensive network in the innovator community, she actively contributes as a thought leader, driving new ideas and transformative solutions. Tenna has had the privilege of learning from some of the industry’s most influential pioneers - David ‘Avo’ Wolfe, Gabriel Cousins, and lots of other trailblazers who have deeply shaped her approach. Their wisdom, combined with her own hands-on experience, has equipped Tenna with the knowledge and tools to help others on their journey to greater health, vitality and longevity.

Her love for detoxification began with a spiritual cleansing retreat in Bali in 2009 - a life-changing experience that ignited her dedication to holistic wellness. Since then, Tenna has been on a mission to blend ancient healing practices with modern science, creating detox protocols that are powerful, safe, and effective. From fermentation and live enzyme therapy to breath-work and herbal remedies, she is endlessly fascinated by the body’s natural ability to heal when given the right support.

“I am proud to have seen such a movement and can now pass on my knowledge. The future is exciting and healing through detoxing is much needed”.
