Amy’s Story: From Fatigue to Fuel
Amy Puzey isn’t just a mother of four, and nutritionist. She’s also a champion runner who knows what it means to push her body to its limits — and beyond.
She’s the 2009 Canadian Mountain Running Champion, winner of the 2015 TransRockies 3-Day Solo, a multiple 50K champion, and a 3-hour marathoner who won the Cowtown Marathon in Texas in 2017 — just months after giving birth to her daughter.
Amy ran competitively for the University of Alberta and Mount Royal University, building a deep understanding of performance, recovery, and endurance from both science and lived experience.
But despite all that strength and discipline, she hit a wall she couldn’t run through: chronic fatigue, relentless exhaustion, and iron levels that just wouldn’t recover — no matter how “healthy” she ate or how many supplements she tried. And she wasn't alone. "In my group of friends, I'd say at least half of us were iron deficient or anemic. It is a constant struggle for female athletes."
The Hidden Culprit: Phytic Acid
Even the cleanest diet can work against you — especially if you’re eating like most runners do. Plant based foods are good for you, but they're also very high in phytic acid.
Common Runner Foods That Block Iron:
- Oats
- Almonds and other nuts and seeds
- Breads and cereals
- Lentils and Chickpeas
- Chocolate
- Quinoa
- Brown Rice
- Soy
- Any food made from a grain, bean, nut or seed
These foods are packed with phytic acid, a compound that binds to iron in your digestive tract and prevents your body from absorbing it. Without realizing it, female runners everywhere are pulling iron out of their systems — and never replenishing it.
The Breakthrough: Phytase Powered Iron
Using her background in nursing and nutrition, Amy discovered the secret to overcoming this iron block: phytase — a powerful digestive enzyme that breaks down phytic acid and unlocks iron absorption.
Goodphyte is the only iron supplement that:
Contains phytase to neutralize phytic acid
Uses bioavailable iron your body can actually use
Works with your diet, no drastic changes required
