Mold and the Respiratory System: What to Notice
Breathing mold-contaminated air can contribute to inflammation, allergies, and symptoms like asthma, wheezing, and persistent cough. Kids can be especially sensitive, and ongoing exposure may raise the risk of repeated infections or school absences.

Key signs
• Asthma symptoms or chest tightness
• Wheezing that does not fully resolve
• Persistent cough
• Frequent respiratory infections

Phase I cytochrome P450 enzymes help the body process mycotoxins in the liver and even inside mitochondria. If this step is not efficient, mycotoxins may build up and impact cellular energy and oxidative balance.

Why can this happen? Genetics, low nutrient cofactors, ongoing inflammation, and exposure to certain metals or chemicals can all play a role.

Interested in a new toxins testing option that helps when cytochrome P450 function is in question? Comment “toxic” for more info.

Your mitochondria help set the tone of your immune response
When a respiratory virus hits, immune cells shift mitochondrial pathways like the citric acid cycle, fatty acid oxidation, and OXPHOS to power defense. Mitochondrial ROS also signal NF-κB, antiviral inflammasomes, and type I interferons. Afterward, you need enough antioxidant capacity to calm things down.

What influences mitochondrial and antioxidant status?
• Nutrition and key enzyme cofactors
• Age-related changes in efficiency
• Ongoing inflammation or allergies
• Environmental toxicants (metals, chemicals)
• Chronic psychological stress

If you want a biochemical snapshot, dried urine Organic Acids testing can highlight where support may help mitochondrial efficiency and immune resilience.

We have something new coming related to metabolic health and toxin insights. Use code “toxic” for exclusive details.

Fall foods for IBD
Enjoy the season while staying mindful of flare patterns. Here are simple ideas to try and then adjust based on your own tolerance.

Active flare: apples, pecans, turkey.
Intermittent symptoms: pumpkin, sweet potato, beets.
Remission or maintenance: unsweetened cooked cranberries, cabbage, beans and legumes.

Additive awareness: some people feel better avoiding products with hydrogenated oils, artificial sweeteners or colors, polysorbate 80, maltodextrin, carrageenan, and carboxymethylcellulose. Choosing simpler ingredient lists can make it easier to spot what works for you.

Xylene Metabolites and Where Exposure Comes From

Metabolites you will see reported
• 2-methylhippurate
• 3-methylhippurate

How exposure happens
Most exposure is through inhalation of vapors. Xylene is present in petroleum and coal tar and is used in motor and aviation fuels. It can also come from automotive emissions, older vehicles with poor emission control, aviation fuel, waste and landfill sites, industrial discharges and spills, and to***co smoke. Many household and workplace products contain xylene or similar solvents, including varnishes, paint thinners and removers, shellac, rust preventatives, lacquers, inks, dyes, adhesives, and various cleaning and degreasing agents. It is used as a solvent for rubbers, synthetic resins, gums, inks, and paints, in fabric and leather treatments, and in making plasticizers, polyester fiber and film, insecticide formulations, and perfumes. Job roles with potential exposure include paint and printing ink work, auto body repair, photographic processing, rubber, leather, plastics, and textile manufacturing, and flooring installation.

Possible effects
Central nervous system depression, changes in neuropsychological and neurophysiological function, anemia and thrombocytopenia, renal issues, irritation of the eyes, nose, throat, or skin, dermatitis, nausea, fatigue, headache, anxiety, shortness of breath, and in rare severe cases cyanosis.

More practical guidance on environmental exposure markers is coming soon. Stay tuned for news.

Meet Sophia.
She’s 36 and hasn’t had a menstrual cycle for 3 years due to hypothalamic amenorrhea.

When Dr. Leah Hechtman met her, she suspected mitochondrial dysfunction. The question became why—what was driving it?

They looked at early life exposures, maternal health, and even generational toxin impact.
🧬 Our mitochondria come from our mothers, so damage can trace back through the maternal line.

Symptoms of Glyphosate Exposure: What to Know
Short-term exposure can cause skin or eye irritation and breathing discomfort, especially for people who apply herbicides or touch recently treated surfaces.

Long-term exposure has been linked in research to issues such as endocrine disruption, insulin resistance/type 2 diabetes, reproductive problems, microbiome imbalance, and mitochondrial dysfunction. Some studies also report associations with non-Hodgkin lymphoma and neurobehavioral concerns, though results are not all the same.

Symptoms often reported: abdominal cramps, nausea or vomiting, headache, dizziness, weakness, mouth/throat irritation, breathing difficulty, and low blood pressure. Severity varies by dose and individual factors.

Why the mixed messages? Major health organizations do not fully agree: IARC labels glyphosate “probably carcinogenic,” while the EPA and EFSA consider it safe when used as directed. That’s why continued research and careful use matter.

When Dr. Leah Hechtman sees elevated 4-OHEstrone or 16-OHEstrone, she starts asking deeper questions.

“Phase 1 estrogen metabolism tells me to look at methylation.”

She reviews:
👉 SAM/SAH ratio
👉 Folate and B12 metabolites
👉 SNPs and nutrient quality

It’s how she uncovers what’s really driving hormone imbalance.
