Michael Hartmann

Founder of naturaveda

Michael Hartmann has spent more than thirty years studying nutrition, micronutrients and the compounds that sit inside ordinary plants. One question has driven that work from the start: why some people stay energetic and active well into old age, while others start struggling with their health decades earlier.

He works across three plant traditions, Ayurveda, Traditional Chinese Medicine and European herbal medicine, and holds all of them to the same standard. Tradition tells you where to look. Current research tells you whether you were right to look there, and at what dose.

In the naturaveda Magazine he explains what the research on an ingredient actually shows, what it does not show, and when a question belongs with a doctor instead of a supplement shelf. He is not a physician, and nothing he writes replaces medical advice.
