WHAT READERS SAY
Review by Lazar Brcic Kostic, Canada, July 10, 2026: "I have finished reading your book, although I know it will take much more time to truly study and fully absorb everything it contains. It is an outstanding book—extremely informative, well organized, and genuinely inspiring. Your book impressed me so much that I purchased a second copy for my son and daughter-in-law. Thank you for writing such an exceptional book."

Foundational Volume: De huid-darm connectie (Dutch Edition) (2019)
The Comprehensive Scientific Reference Work on the Gut-Skin Axis
About the Textbook
Published in 2019, The Skin-Gut Connection is the encyclopedic foundational volume that established the clinical framework for the entire series. Categorized as advanced (para-)medical professional literature, this 632-page textbook provides an exhaustive, scientifically backed analysis of how gastrointestinal homeostasis directly governs cutaneous health.
The text explores the complex biochemical parameters driving the skin-gut axis, including mucosal immunity, sebaceous lipid composition, pH dynamics, vitamin D metabolism, and targeted nutritional physiology. Throughout the volume, the human microbiome and systemic immune pathways serve as the core investigative themes, making it an indispensable reference blueprint for root-cause dermatology.
