The Unprocessed Truth

Spirit Studios

I’m Sunna Van Kampen. After years of battling constant illness, I realised that the health headlines we’re fed are often nothing more than clever marketing. Now, I’m on a mission to cut through the noise. I founded Tonic Health to change the industry, and now I’m on a mission to bring that same clarity to your life.

Each week, I’m grilling the UK’s leading nutritionists, doctors, and scientists to get the facts behind the fads. We’re stripping away the jargon to answer your burning questions about what we’re really putting in our bodies.

From the ‘healthy’ habits that are secretly holding you back to the simple changes that actually deliver results, we’re exposing the good, the bad, and the essential facts.

No more confusing trends, no more industry spin - just The Unprocessed Truth.

Join me every week as we finally uncover what it actually takes to thrive in the modern world.
