Why Hookworms?

Forty years ago, I was diagnosed with severe colitis. Medical doctors told me I needed surgery or I might not survive. I chose a different path and am still here today. That experience became the foundation of my life’s work.

Ten years ago, my 17-year-old son was diagnosed with primary biliary sclerosis—one of the most aggressive autoimmune liver diseases. As a naturopathic doctor with 20 years of clinical experience at that point, I had every conventional and alternative tool available. None of them worked. His liver inflammation was severe.

I gave him hookworms. Two months later, his liver tests returned to normal. They have remained normal for the past eight years.

That experience changed everything. This book explains why hookworms succeed where everything else often fails and how they can help people with autoimmune conditions, chronic inflammation, allergies, and related disorders.

The Only “Alive” Approach

Hookworms are not parasites in the traditional sense. They are ancient symbiotic organisms that have co-evolved with humans for millions of years. They only thrive when their host is healthy, so they actively work to keep you well.

Modern hygiene has removed these tiny helpers from most people’s bodies. For many—especially those with “Viking” genetics (highly reactive immune systems shaped by Northern European ancestry)—this absence creates chaos. Without the natural regulatory signals hookworms once provided, the immune system overreacts, driving chronic inflammation throughout the body.

Hookworms act like a living thermostat. They sense inflammation and release precise signals that calm the immune response—more accurately than any drug and without the side effects of steroids or immunosuppressants. They also organize gut bacteria, produce anti-inflammatory compounds, support stem-cell repair, balance stress hormones, improve sleep, and reduce anxiety.

They restore the missing piece our bodies evolved to expect.

Real People, Real Results

Julie’s Story – Joint Pain and Thyroid Issues
Diagnosed with chronic inflammation in her thyroid and joints, Julie found medications offered only partial relief with heavy side effects. After starting hookworms, the pain and fatigue lifted almost immediately. Within three months she was back lifting weights, practicing yoga, and living an active life again. Her husband said he had “his old wife back.”

Kathy’s Story – Long-Term Hypothyroidism
Kathy had battled hypothyroidism for over thirty years, along with severe food sensitivities and anxiety. Two years after beginning hookworm therapy, her TSH normalized, she stopped thyroid medication entirely, and her hidden food allergies disappeared. She feels she has her life back.

Rose’s Story – Chronic Back Pain & Menstrual Issues
For years Rose suffered debilitating lower-back pain (especially after pregnancies) and severe menstrual bleeding and clotting. In July 2020 she started hookworms. Within one day she was walking upright. Within three days the pinching pain was gone. Four months later her periods had normalized dramatically, her energy returned, and she finally tackled long-postponed projects. “I am thankful and humbled by the work they do.”

Matt’s Story – Crohn’s Disease
Diagnosed with Crohn’s Disease at age eight, Matt’s health continued to worsen despite being on many different medications. His family feared he would slowly decline with no real cure. After starting hookworms, Matt feels great. For the first time in ten years he has complete freedom of diet—which essentially gives him freedom in life.

AZ’s Story – Food Allergies, Fibromyalgia & Barrett’s Esophagus
AZ suffered from multiple severe food allergies, fibromyalgia-like muscle pain, tennis elbow, and Barrett’s Esophagus. After reading the book twice and attending a seminar, he started with 5 hookworms in March 2019 and reached 20. Within months he could eat gluten again (including real pizza) with zero symptoms. His Barrett’s Esophagus cleared, tennis elbow disappeared, and at age 61 he was doing pull-ups at the gym.

These stories reflect what I see regularly in practice. Hookworms frequently deliver life-changing results for conditions that previously resisted every other treatment.

Why NA457 (“Wormy”) Is Our Preferred Strain

After years of clinical experience, the NA457 strain has proven to be the safest and most effective for most people. Key advantages:

It cannot reproduce in the human body—you control the exact number.
Minimal side effects while settling in.
Stays small (no longer than half an inch) and lives only in the small intestine.
Does not cause anemia.
Safe to use alongside conventional medications.
Easily eliminated if ever needed.
Excellent at balancing gut bacteria, calming the nervous system, reducing anxiety, improving sleep, and regulating stress hormones.

Different helminth lineages have different “personalities.” NA457 has consistently delivered reliable results across a wide range of conditions.

Serum Specific Helminths
For even greater precision, we offer Serum Specific Helminths — an advanced technique in which the hookworm larvae are preconditioned with a small sample of the patient’s own blood serum before they are introduced. This personalizes the worms to the individual’s unique immune profile. The approach is utilized in a variety of clinical situations, including for patients who are currently undergoing chemotherapy as well as those who are not.

The Bigger Picture: Viking Genetics and Modern Disease

Many autoimmune patients carry powerful immune genes that once provided a survival advantage. In our sanitized modern world, those same genes—without the regulatory influence of hookworms—turn against the body, creating allergies to foods, bacteria, viruses (including Lyme and Epstein-Barr), and even normal gut microbes.

Hookworms do not “cure” disease in the conventional sense. They re-establish the symbiotic relationship our physiology expects. The result is reduced inflammation, restored immune regulation, and dramatic recovery in conditions that resisted every other treatment.

Practical Considerations & Final Thoughts

Managing a living organism requires attention and nurturing—unlike taking a pill. The relationship is dynamic. Hookworms respond to your body’s state and adjust accordingly. We carefully select the right strain and dosage (and, when appropriate, apply the serum-specific personalization) for each person. Because the worms are easily controlled and reversible, they offer a flexible, natural option suitable for all ages.

Autoimmune conditions often trap people on a seesaw between toxic drugs and extremely restrictive lifestyles. Hookworms offer a third path—one that works with your body instead of against it.

This is not theory. It is the lived experience of my family, my patients, and hundreds of others who have welcomed their body’s little friend back and regained their health.

If you or a loved one struggles with chronic inflammation or autoimmune disease, hookworms may be the missing piece you have been searching for.

Welcome home to your body’s natural balance.
