The founder who brought phytase to human health, paired with the world's foremost authority on the phytase enzyme.
You are not what you eat. You are what you absorb.


In February 2026 Cronometer added phytic acid to the nutrients its app tracks, and built it into a new calcium absorption score that estimates how much calcium you absorb rather than how much you ate. Cronometer brought Amy on to explain it to their users. The absorption gap moved from an invisible mechanism to a metric on a screen.

Amy Puzey is a researcher and the founder and CEO of Goodphyte, the company that brought phytase to human health. She is the visionary who saw the solution to a problem no one else could see.
Her passion and dedication to bringing this knowledge to the world are astounding, and she has been relentless in her pursuit. She has advanced the clinical research and, in the process, transformed lives across the globe.
Amy's life's purpose is closing the nutritional gap that phytic acid creates in the standard diet. Plants evolved phytic acid to bind essential minerals in seeds so the germinating plants would have everything they needed. Unfortunately, humans don't make much of the phytase needed to break down phytic acid and absorb the minerals and amino acids found in the grains, legumes, nuts, and seeds at the base of much of what we eat. This nutritional gap is a hidden driver of fatigue, inflammation, autoimmunity, and chronic disease.
Amy discovered the solution to closing that gap: supplementing phytase, the enzyme that unlocks the iron, copper, zinc, magnesium, calcium and amino acids bound up by phytic acid and frees them so people can absorb them. She founded Goodphyte in 2019 to bring that solution to the world. The problem she is solving is known as "hidden hunger": micronutrient deficiency that persists even when food is abundant.
Amy was bold enough to commercialize a product at doses high enough, within safety limits, to start seeing real effects, including autoimmune disease remission reported both clinically and anecdotally. Don't believe it? Most people don't, until they read the science and the testimonials. Autoimmune diseases are falling.
Amy worked as a nutritionist in private practice for nine years before turning her focus to phytase.
She is also an accomplished endurance athlete. Amy has won multiple single-day and multi-day ultra races, won the Canadian Mountain Running Championship, and represented Canada twice at the international level. Before Goodphyte she led 5 Peaks Adventures, Canada's national trail-running series, for nine years as CEO and National Race Director.
Dr. Mike Bedford is widely recognized as the world's foremost authority on the phytase enzyme. He is the peer-reviewed science behind Goodphyte.
Over a research career spanning four decades and more than 250 publications and patents, Dr. Bedford established much of the mechanistic understanding of how phytic acid (also called phytate) locks up the minerals in plant foods, and how phytase breaks it down to release them. His work drove the commercialization of phytase in animal nutrition and its translation into human health.
In 2019 that science crossed into human nutrition when Amy Puzey and Goodphyte became the first to bring phytase to market for human health, drawing directly on the evidence base Dr. Bedford's research helped build. He serves as the head of Goodphyte's scientific advisory team.
Dr. Bedford is a compelling guest for science-heavy podcasts where peer-reviewed credentials and mechanistic depth matter: from the chemistry of the phytate molecule to superdosing, gut immunity, and why four decades of livestock research translate directly to human mineral nutrition. He appears alongside Amy Puzey as a researcher-and-founder pairing.
Nutrition software started modeling absorption instead of intake alone. What that changes for anyone measuring their own health.
Why billions are micronutrient-deficient even when calories are abundant.
The phytic acid problem in whole foods, and why intake does not equal absorption.
The enzyme that frees the minerals phytic acid locks away, and what it could change for chronic disease.
Chasing the absorption gap from clinical practice to the lab to a company.
Why cyclical iron and mineral needs are so often overlooked, and what closing the gap changes.
How mineral absorption translates into real autoimmune and metabolic outcomes.
