Unlock the Science of Living Well
I’m Dr Jenna Macciochi, immunologist, author, and teacher of breathwork and meditation. I help people understand the science of staying well, optimising their health, performance, and longevity through every stage of life.
A little about me…
Hi, I’m Jenna. I’ve spent over 20 years studying the immune system, but what really drives me is helping people like you understand how their mind and body work as one, so you can live well for longer.
I’m not just interested in lab results. I want to show how the science of psycho-neuro-immunology can shape everyday choices, not only our physical health, but our moods, energy, and sense of self.
My approach blends rigorous research with a human touch. I translate complex biology into practical tools that feel doable, sustainable, and empowering.
I’m the author of three books: Immunity: The Science of Staying Well, Your Blueprint for Strong Immunity, and Immune to Age. Through them, I share how modern immunology can help us build lifelong health from the inside out.
My work and commentary have featured across BBC, The Guardian, The Times, Women’s Health, among others. I regularly share my expertise internationally as a speaker, consultant, and educator, helping people connect the science and art of staying well.
