Hernan Jaen

Since childhood, Hernan Jaen struggled with severe allergies that worsened through adolescence and into adulthood. For more than ten years, he depended on daily medication to control his symptoms. After visiting numerous conventional doctors who insisted there was no cure, everything changed when a close family member began treatment through Functional Medicine—and experienced a complete transformation. That revelation inspired Hernan to study this remarkable science and to spread its message globally through his books.

Hernan stays continuously updated with the latest scientific advances in Functional Medicine. As a lawyer by profession, he is also a rigorous researcher who constantly seeks scientific evidence to support every health-related topic he writes about.

Hernan is also a best-selling author, thanks to his book Healing Autism Symptoms Naturally. Within just a few days of its release, the book achieved remarkable sales, quickly rising in the rankings and establishing itself strongly on Amazon. The success came as a surprise to Hernan, but it confirmed what he already sensed: the global interest and need for guidance in this area is immense. This experience helped him realize that one of his life’s purposes is to improve the quality of life of many people around the world through his nine books.
