The Gluten-Free Life Coaching and Consulting

Jennifer Formantes, CGP, CHC
Certified Gluten-Free Practitioner | Certified Health Coach | Gluten-Free Coach & Educator

Hi, I’m Jennifer Formantes, a Certified Gluten-Free Practitioner, Certified Health Coach, and founder of The Gluten-Free Life Coaching & Consulting. My journey with gluten-free living began from a deeply personal place: after becoming bedridden due to an autoimmune disease, I realized that in order to heal, I needed to reduce inflammation, repair my gut, and support my immune system. Through extensive research and trial and error, I transformed my nutrition and lifestyle. It didn’t happen overnight, but learning how to live fully and joyfully gluten-free changed my life. Now, I help others do the same.

I coach individuals, families, and communities on how to build lasting gluten-free habits that support healing before, during, and after illness. No matter what stage of healing you are in, confused on where to start, or simply wanting to feel better in your body, I’ll walk beside you every step of the way. My approach blends practical tools, evidence-based guidance, and compassionate support to make gluten-free living simple, sustainable, and empowering.

I know firsthand how overwhelming—but also freeing—this journey can be. That’s why I focus on realistic changes, meaningful education, and personalized coaching that truly sticks. Through one-on-one sessions, workshops, and online resources, I help people take the guesswork out of gluten-free living and feel confident in their choices.
You deserve to feel well, eat safely, and live fully—and I’m here to help you get there."

Tumor-Associated Antigens (Immune Reactivity)

Tumor Markers

We screen for immune activation against certain tumor- related antigens.

Why:

This is not a cancer diagnosis – it’s an immune “red flag” that can help guide early, proactive intervention and lifestyle shifts if needed.

Toxin-Related Genetics

Detox Genetics Panel

We assess SNPs that impact detox pathways, hormone clearance, and antioxidant defense.

Why:

Your genetic blueprint helps us understand where your
system may need extra support. We don’t treat the genes –
we support the pathways.

BACK TO FUNCTIONAL TESTS

Total Immunoglobulin Levels (IgG, IgA, IgM)

Serum Immunoglobulins

We evaluate your baseline immune capacity through the main antibody classes.

Why:

If you’re chronically low, you may not mount proper responses to infections, foods, or toxins – or you might overreact to benign exposures.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Autoimmune Reactivity (Early Screening)

Autoimmunity Zoomer

We screen for antibodies against tissue-specific proteins: thyroid, pancreas, joints, brain, gut lining, skin, and more.

Why:

Autoimmunity doesn’t start with symptoms – it starts with silent immune confusion. Catching these early lets us shift the terrain before disease manifests.

BACK TO FUNCTIONAL TESTS

Methylation Function

Methylation Panel

We check methylation metabolites and cofactors (like B12, folate, homocysteine) to see how efficiently your body is methylating.

Why:

Methylation is essential for detox, DNA repair, mood regulation, and immune modulation. If this system is sluggish, nothing else flows properly.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Gut & Microbiome Balance

Gut Zoomer

We look at over 100+ species of bacteria, yeast, parasites, viruses, and gut inflammatory markers.

Why:

Your gut is home to ~80% of your immune system. If it’s imbalanced — everything else is. We assess for dysbiosis, infections, and signs of intestinal inflammation.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Toxins: Chemicals, Mold & Heavy Metals

Total Tox Burden (Urine)

This comprehensive three-panel test evaluates your total toxic burden by measuring environmental chemicals, mold-related mycotoxins, and heavy metals that can silently disrupt your energy, immunity, and brain health.

Why:

These toxins bioaccumulate and block healing. They disrupt hormones, immune balance, mitochondria, and the brain. You can’t detox what you don’t detect.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Oxidative Stress & Antioxidant Status

Oxidative Stress Profile

We measure lipid peroxidation, DNA damage, and your glutathione and antioxidant enzyme activity.

Why:

Oxidative stress is at the root of aging, autoimmunity, poor healing, and fatigue. We need to know if your body is stuck in “damage mode.”
ORDER NOW
BACK TO FUNCTIONAL TESTS

Grain Reactivity (Beyond Wheat)

Grain Zoomer

We assess your immune response to non-gluten components of grains like quinoa, barley, buckwheat, rye, rice, oats, sorghum and teff.

Why:

Gluten-free doesn’t always mean inflammation-free. Some “gluten-free” grains can still trigger immune responses in sensitive individuals.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Nut Reactivity

Nut Zoomer

We test your immune response to almonds, cashews, walnuts, pistachios, pecans, hazelnuts, and more.

Why:

Non-IgE (delayed) food reactions to nuts are common and can cause low-grade inflammation, gut disruption, and skin flare-ups.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Lectins

Lectin Zoomer

Lectins are sticky proteins found in plants (like legumes and grains) that can bind to gut lining and trigger inflammation in some people. This test looks at immune reactivity to a wide range of dietary lectins.

Why:

For sensitive individuals, lectins can contribute to joint pain, skin issues, digestive problems, and chronic immune stress – even when eating “healthy” foods.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Wheat Reactivity & Leaky Gut

Wheat Zoomer

We look at your immune response to over 30 wheat peptides and measure intestinal permeability (a.k.a. leaky gut) via markers like zonulin and occludin.

Why:

Wheat is a top immune trigger. If your gut lining is compromised, inflammation becomes systemic and unpredictable.
ORDER NOW
BACK TO FUNCTIONAL TESTS

Dairy Reactivity (All Components)

Dairy Zoomer

We test your immune response to all parts of dairy: casein, whey, butyrophilin, and even cross-reactive peptides.

Why:

Dairy reactivity is often missed by standard tests – but can silently contribute to joint pain, skin issues, anxiety, gut and brain inflammation.
ORDER NOW
BACK TO FUNCTIONAL TESTS

ApoE Genotype

ApoE Genetic Test

We use this insight to personalise your nutrition, detox, and brain-health strategy so we can reduce cognitive risk and support how your body processes fats long before symptoms appear.

Why:

Identifies your ApoE status (e.g. E2, E3, E4) to assess genetic risk for cognitive decline and how your body handles fats and detox.

BACK TO FUNCTIONAL TESTS

Brain & Viruses

Neural Zoomer Plus

We assess for antibodies to brain tissue, markers of blood- brain barrier permeability, and neurotropic viruses like Epstein-Barr (EBV), HHV-6, and CMV.

Why:

We assess for antibodies to brain tissue, markers of blood-
brain barrier permeability, and neurotropic viruses like
Epstein-Barr (EBV), HHV-6, and CMV.

Mikania Guaco

“Guaco” is Sun Horse Energy founder Dan Moriarty’s favorite herb, and the reason why he’s still alive. Traditionally, it’s a well-known herb for snake bites, scorpion stings and other venomous creatures. Guaco acts as a non-steroidal bronchodilator, meaning it opens up the airways without steroids. As a result of guaco opening up the airways, the alveoli (tiny air sacs in the lungs) are better able to accept oxygen transfer and get rid of carbon dioxide. In Brazil, Guaco syrup is one of the most popular herbal medicines used to treat the symptoms of asthmatic bronchitis, cough and hoarseness.

Osha Root

A traditional Native American herb, Osha is also known as “Bear Root”. Native Americans noticed that when bears emerged from hibernation, the first thing they did after being in a state of torpor for 4 months was not feast on salmon or drink water, but rather, dig up osha and eat it. Why? It decongests and wakes up the lungs. Native Americans who used Osha were able to run further, and treat their colds and congestion. Modern research studies suggest Osha may support the immune system by offering protective effects against oxidative damage.

I want to thank you for your existence. I want you to know that functional medicine has changed my life, well the life of my autistic son. So much so that I plan on taking the Functional Medicine Health Coach Certificate and work with my new friend who is now a Functional Medicine Doctor from the Institute of Functional Medicine and spread the word on GI testing and how finding the underlying issues will help eliminate autistic traits. 

I hope to be able to meet you one day so I can share this great news with others. Changing my son’s diet has changed him. Food is medicine!! By the way, I’m cooking my rutabaga. I’m Italian and never grew up with these. With love.

April Renee

Just wanted to tell you that you’re amazing! You are helping so many people all over the world! Including me! Thank you so very much, Dr. Tom O’Bryan!

Patricia Puddle

Good morning Dr. Tom, Would just like to say thank you! This time last year I was going through a hell of a time with my gut. Terrible indigestion on a regular basis, feeling as if I had eaten a boulder and the tiredness was doing my heed (scottish for head) in! With two young girls being tired is not an option!

I went to the doctors on a number of occasions and they decided to prescribe omeprazole to mask the problem, sorry help my problem. I decided taking these drugs was not an option for me! So I started googling the life out of it!! Low and behold you started popping up!! Oh and Gluten intolerance! 

Your advice has been second to none! You have in my case really simplified what gluten does to my body and now that I have cut it out (which as it appears in lots of foods, some I can’t understand) I have found that my symptoms very quickly reduced and now I’m a year down the line they have gone for the vast majority of the time!! For that I’m truly grateful. I now follow you on YouTube and Instagram, which continues to educate me and the importance of gut health. I look forward to your future advice. Yours faithfully,

Gary Christie

Cordyceps

Cordyceps, a genus of mushroom, gained lots of attention after Chinese long-distance runners performed impressively at international competitions in the 1990s and early 2000s. Along with high-altitude training, supplementing with cordyceps was part of their intense training program. A research study concludes that cordyceps improves tolerance to high-intensity exercise after supplementation with it because the fungus is thought to increase blood flow, enhance oxygen utilization; it also acts as an antioxidant. It also has powerful anti-tumor properties, the ability to regulate the endocrine system, enhance your immune function, and protect the kidneys, lung, liver, and other organs.
