The science behind Goodphyte for Northwest Territories Indigenous governments and communities — and the published research it rests on.
A reference for community health and food-security advisors. Goodphyte is a dietary supplement, not a treatment for any disease.
Food security is also an absorption problem. The shelf-stable staples that survive the cost and logistics of the North — flour, rice, oats, pasta, cereal, and canned legumes — are the foods richest in phytic acid, the storage form of phosphorus in seeds and grains. Phytic acid works like a magnet: it binds iron, copper, zinc, calcium, and magnesium in the gut and holds them so the body cannot absorb them, both from the grain food itself and from other foods eaten in the same meal (Hallberg 1989; Sandberg 2002; Kumar 2010). Humans produce little of the enzyme that breaks it down (Brouns 2022).
The result can be adequate calories with inadequate micronutrients — what the World Health Organization calls “hidden hunger.” A diet reads as sufficient on paper while the body runs short of the minerals that food is supposed to deliver.
Micronutrient inadequacy is well documented in Northern and Indigenous populations. A major review of First Nations and Métis nutrition in the Northwest Territories identified inadequate intakes of vitamins A, C, D and E, and of calcium, iron, magnesium, phosphorus, zinc and folate, with children, women, and remote communities particularly vulnerable (NCCIH review). Iron-deficiency anemia is a recognized public-health issue among children in remote northern Indigenous communities, and studies of Arctic Indigenous populations repeatedly find high rates of suboptimal vitamin D status. Declining access to traditional foods and greater reliance on expensive, nutrient-poor market foods are identified as key drivers.
Phytase, the enzyme in Goodphyte, breaks phytic acid apart and releases the minerals it was holding, so the body can absorb them from the food already on the plate. Human studies show phytase can substantially improve the absorption of the minerals phytic acid binds, particularly iron and zinc (Troesch 2013; Sandberg 1996), and reducing dietary phytic acid increases calcium absorption (Hambidge 2005).
Iron and copper absorbed together; copper puts iron to work carrying oxygen. Relevant to fatigue and reduced work capacity from subclinical iron depletion, which precedes clinical anemia (Zimmermann & Hurrell 2007).
Calcium, magnesium, and phosphorus freed for bone building in children and bone maintenance in Elders, from the staple foods already on the table (Hambidge 2005).
Zinc unlocked to support immune function through long, low-light winters when infections spread hardest (Prasad 2008).
More of every gram of protein reaching the body, and magnesium freed for restful sleep, which is itself linked to daytime function (Abbasi 2012).
We are not asking anyone to take our word for it. Here is the evidence as it stands, including where it is thin.
| Claim | Primary source | Evidence |
|---|---|---|
| Phytic acid inhibits iron absorption, dose-dependently. | Hallberg 1989 | Human |
| Added phytase increases iron absorption from a phytic-acid-rich meal. | Sandberg 1996 | Human, controlled |
| Phytase improves iron and zinc bioavailability from phytic-acid-rich foods. | Troesch 2013 (reviews 12 human iron & 5 zinc studies) | Human, systematic review |
| Reducing dietary phytic acid increases calcium absorption. | Hambidge 2005 | Human |
| Subclinical iron depletion, short of anemia, impairs energy and work capacity. | Zimmermann & Hurrell 2007 | Human, review |
| Phytase improves mineral status and protein use at scale. | Four decades of poultry & swine nutrition literature | Animal only |
| Goodphyte specifically improves mineral status in a human population. | Unpublished; Goodphyte human trial data available to advisors under confidentiality | Not yet shown |

“I am 76 years old and have always had a sensitive digestion system resulting in gas, bloating, and pain after digesting certain foods. The difference in 2 weeks is amazing. To date I have not had cramping or bloating. I am sleeping better as well. I even notice the pain in my shoulders and knees is less. I am so thankful!”
Mary — age 76 · Newmarket, Ontario
“First day on Goodphyte: came home from work and moved 3 whole bedrooms in the house. Wife was in shock. Next day: first 7 full hours’ sleep since diagnosis. Four weeks in: no 2–5pm fatigue crash, more energy, better mood, restful sleeps.”
Tyler — husband & father of two, age 43 · living with MS
“I’ve struggled with chronic constipation and IBS for my entire life … For the first time I can remember, I’ve been regular for the last week. I’m shocked, as nothing in the past has ever improved my digestion. This has been a complete game changer for me.”
Shared anonymously — lifelong digestive issues
“I have been taking 5 capsules of the original Goodphyte and feeling IBS relief in the form of less bloating and gas, more regular bowel movements, reduced reactions to food.”
Sharon Walker — living with IBS
“I’m a nurse … I’ve not felt this good in such a long time. My cognitive ability — it’s like a light bulb has switched on again. Today was my third day … I have so much more energy: I was in my clinic all day, came home, and tidied the full house.”
A nurse — shared anonymously · three days in
“I struggled with extreme fatigue. … Once I started taking phytase, my fatigue went from moderate to very mild — I couldn’t believe it! I had so much energy, my mood improved.”
Alison D. Elliott — teacher & mother · living with MS
“I haven’t had a nap for a long time now since taking phytase … that’s been a huge change.”
Sandra Yaworski — running coach living with rheumatoid arthritis; her full interview is on the Goodphyte YouTube channel
“I used to have mid-day crashes of fatigue and that has stopped. My energy and alertness are consistent day to day.”
