Follow for Updates →O'Neill Labs is the personal brand and product studio of Niall O'Neill — born in Dublin, Ireland. Diagnosed with coeliac disease as an infant, Niall developed an early and deep understanding of how the body responds to what we put into it.
That curiosity led him across disciplines — judo, boxing, GAA coaching, dance, business, and computer science — and eventually to a simple conclusion: most people don't fail from lack of information. They fail from lack of structure.
O'Neill Labs exists to close that gap — with books, tools, and content that turn good intentions into repeatable systems.
"Most people don't fail from lack of information. They fail from lack of structure."
— Niall O'Neill, Upgrade Your Body
O'Neill Labs sits at the intersection of health science, technology, and habit design. Every product we build is grounded in one belief: a better system changes more than your habits — it changes how you show up in every area of your life.
