Profound and mysterious fatigue plagues many people. Sometimes the cause is related to mold toxins from water damaged buildings or mold contaminated foods. Certain supplements are useful in helping eliminate mold and mycotoxins from the body. In this article, we delve into how the body handles mycotoxins, genetic susceptability, and the role that nutritional supplements can play in binding mold and mycotoxins to help remove them from the body.

What Are Mold and Mycotoxins?

Mold and mycotoxins are common concerns that can affect indoor environments, posing potential risks to health. Mold refers to various types of fungi that thrive in damp and humid conditions, often found in areas such as bathrooms, kitchens, basements, and poorly ventilated spaces. When mold spores land on damp surfaces, they can multiply and form colonies, releasing spores into the air. Mycotoxins are the toxic substances produced by certain molds as they grow, which can contaminate indoor air and surfaces.

Exposure to mold and mycotoxins can lead to a range of health symptoms, varying in severity depending on factors such as the individual’s sensitivity and the type and amount of mold present. Common symptoms of mold exposure may include respiratory issues such as coughing, wheezing, and throat irritation, as well as nasal congestion, sneezing, and eye irritation. Some people may also experience skin rashes, fatigue, headaches, and worsening of asthma symptoms.

Several factors can contribute to the growth of mold and the production of mycotoxins indoors. High humidity levels, water leaks or flooding, inadequate ventilation, and poor building maintenance are common culprits. Additionally, certain building materials, such as drywall and ceiling tiles, can provide an ideal environment for mold growth if they become damp or water-damaged. Poor indoor air quality and prolonged exposure to mold-contaminated environments can worsen health issues and increase the risk of developing respiratory problems and other adverse health effects. Understanding the causes and symptoms of mold and mycotoxin exposure is crucial for effectively addressing and mitigating these potential health hazards.

Mycotoxins in The Body

Mycotoxins enter the body through breathing the air in a water damaged building or eating contaminated food such as grains, nuts, spices, and coffee. Once inside the body, mycotoxins are absorbed into the bloodstream and distributed to various organs including the liver for detoxification.

The liver’s ability to detoxify and excrete mycotoxins can be impaired for several reasons. Genetic variations may decrease the efficiency of detoxification enzymes, while liver overload from prolonged exposure or existing liver conditions can further hinder this process. Nutrient deficiencies can impair the liver’s detoxification capabilities. Phase 1 liver detoxification requires nutrients such as B vitamins (B2, B3, B6, B12), folate, glutathione, and antioxidants (vitamin C, vitamin E), while Phase 2 detoxification relies on compounds like glutathione, amino acids (glycine, taurine, glutamine), sulfur-containing amino acids (methionine, cysteine), and molybdenum. These factors can compromise the liver’s detoxification effectiveness in susceptible persons, potentially leading to an accumulation of mycotoxins in the body.

Genetic Vulnerability To Mold

Genetic factors are another reason people vary greatly in their ability to detoxify and excrete mycotoxins. The HLA (Human Leukocyte Antigen) genes are important for the immune system’s ability to distinguish between self and non-self molecules. The HLA genes control how antigen presenting cells respond to mycotoxins. Certain HLA gene patterns can make individuals more susceptible to chronic inflammatory responses when exposed to the mycotoxins found in water-damaged buildings.

This genetic pattern can lead to chronic inflammatory responses when exposed to environments contaminated with mold. This condition is often referred to as Chronic Inflammatory Response Syndrome (CIRS). CIRS results when alterations in the antigen presenting cells cause a failure to make specific antibodies to clear mycotoxins. CIRS arises from the immune system’s use of prolonged inflammation to clear the unrecognized pathogen.

Research suggests that nearly a quarter of the population carries genetic variations in their HLA genes that make them more susceptible to mold illness, also known as Chronic Inflammatory Response Syndrome (CIRS) when exposed to environments with high levels of mold toxins. These individuals may have a harder time clearing mycotoxins from their bodies due to an impaired ability to recognize and respond to these toxins, leading to prolonged exposure and accumulation in the body, which can trigger a range of chronic symptoms and health issues.

Urine Tests For Mold Exposure

Testing For Mold Toxicity

In the NutriScape Lab Shop, there are two urine tests for mycotoxins. There are probably countless other mycotoxins that could cause issues that have not yet been discovered.

The MycoTOX (affiliate link) from Mosaic Diagnostics tests for:

  • Gliotoxin
  • Zearalenone
  • Verrucarin A

  • Aflatoxin M1
  • Chaetoglobosin A
  • Citrinin
  • Dihydrocitrinone
  • Enniatin B1
  • Mycophenolic Acid
  • Ochratoxin A
  • Roridin E
  • Sterigmatocystin

The Total Mycotoxin Panel (affiliate link) from Real Time Laboratories tests for:

  • Gliotoxin
  • Zearalenone
  • Verrucarin A

  • Aflatoxin B1
  • Aflatoxin B2
  • Aflatoxin G1
  • Aflatoxin G2
  • Isosatratoxin F
  • Ochratoxin A
  • Roridin A
  • Roridin E
  • Roridin H
  • Roridin L-2
  • Satratoxin G
  • Satratoxin H
  • Verrucarin J

For people with certain HLA gene variants and mold illness (often referred to as Chronic Inflammatory Response Syndrome, or CIRS), urinary excretion of mycotoxins may not be efficient. This inefficiency can lead to an accumulation of mycotoxins in the body, contributing to the ongoing symptoms of mold illness. Consequently, improving detoxification pathways through dietary adjustments and binder supplements is necessary to improve the excretion of mycotoxins and alleviate symptoms.

The liver processes mycotoxins and releases them along with the bile into the intestines. When there is no fiber or other binders in the intestine, these toxins can easily be reabsorbed into the bloodstream rather than being eliminated from the body in the stool. Binders work by physically binding to the mycotoxins in the gut, preventing their reabsorption.

Binders act like sponges that cling to the mycotoxins and help increase their direct excretion through the feces. This mechanism effectively reduces the body’s toxic burden by interrupting the cycle of toxin recirculation and aiding in the detoxification process. Common binders used include activated charcoal, bentonite clay, and specific types of fiber, each with unique properties that make them effective against different toxins. By incorporating binders, people with mold illness can improve their ability to clear mycotoxins.


Different types of binders have unique chemical properties and mechanisms of action so they vary in their ability to bind the different mycotoxins. Depending on the exact types of mycotoxins you are trying to remove, some binders will work better than others. The best researched binders are:

  • Cholystyramine: This is a prescription medicine that was designed many years ago to bind cholesterol in the gut. It is highly effective at binding Ochratoxin A.
  • Activated Charcoal
  • Clay
  • Glucomannan Fiber
  • Chlorella
  • Okra Fiber
  • Probiotics: It is a good idea to alternate various types of probiotics.
    • Saccharomyces boulardii
    • Lactobacillus species


What many do not realize is that these organisms can also directly bind to mycotoxins. Lactobacillus strains work to directly bind Aflatoxins, especially the B1 variety. The specific strains are L. pentosus and L. beveris. Another promising strain is L. plantarum C88. This strain works not only to bind to Aflatoxins but also by upregulating the antioxidant activity of glutathione s-transferase. It also shows great binding capacity to the common mycotoxin, Sterigmatocystin.

Strains of saccharomyces also work well to bind mycotoxins. S. cerevisiae has been shown to bind tightly to aflatoxins. It has also shown great efficacy in binding to OTA and Zearalenone. Saccharomyces boulardii, clinically, has shown great efficacy against Gliotoxin. It has also shown efficacy in reducing Aspergillus and Fusarium molds in the GI tract. This will indirectly reduce mycotoxins, as it reduces the producers of mycotoxins including Zearalenone, Enniatin B, OTA, Gliotoxin, and Aflatoxins. Mannan oligosaccharides (MOS) are prebiotics derived from the outer cell wall of S. cerevisiae. This prebiotic has been shown to bind to Citrinin, which a wide variety of molds produce.

Mycotoxins in Food

A low mold diet focuses on minimizing exposure to molds and mycotoxins by emphasizing fresh, whole foods and avoiding those known for mold susceptibility. This includes opting for fresh fruits and vegetables (while being cautious with mold-prone items like berries), choosing fresh, unprocessed meats, poultry, and fish over aged or processed varieties, and selecting whole grains such as quinoa and brown rice instead of mold-prone grains like corn. Dairy alternatives, fresh or roasted nuts and seeds (avoiding peanuts, pistachios, and Brazil nuts due to higher mold risk), and limiting high-sugar and leftover foods are recommended to reduce mold growth opportunities. Alcoholic beverages, especially beer and wine, should be avoided due to their potential mold content. Proper food storage and selection, such as choosing organic produce and avoiding cooking methods that introduce moisture, are also key components of maintaining a low mold diet. For those with mold sensitivities or related health concerns, consulting with healthcare professionals for personalized dietary advice is advisable. Mosaic Diagnostics has put together this resource showing the possible food sources of mold contamination.

What Other Lab Tests Might Be Helpful In Managing Mold and Mycotoxins?

Several lab tests can be helpful in managing mold and mycotoxin exposure. These tests can provide valuable insights into the presence of mold in the environment, the extent of exposure, and any potential health effects. Some lab tests that may be useful include:

  • Visual Contrast Test: Failing the Visual Contrast Test (VCS) indicates biotoxin illnesses including either mold exposure (as seen in conditions like Chronic Inflammatory Response Syndrome, CIRS) or Lyme disease. The rationale behind the test is that biotoxins can affect the nervous system, including parts of the brain involved in processing visual information, potentially leading to a decreased ability to distinguish visual contrasts.

  • Mold Testing: Various methods, such as air sampling, surface sampling, or dust sampling, can be used to detect the presence of mold in indoor environments. These tests can help identify the types and concentrations of mold spores present, providing information about potential sources of exposure.
  • Mycotoxin Testing: Laboratory analysis of biological samples, such as urine or blood, can detect the presence of mycotoxins in the body. Mycotoxin testing can help assess the extent of mycotoxin exposure and evaluate its potential health effects on individuals.
  • IgE/IgG Testing: Allergy testing, including IgE and IgG antibody testing, can help identify immune reactions to specific mold species or mycotoxins. IgE testing is commonly used to diagnose mold allergies, while IgG testing may indicate past or ongoing exposure to mold or mycotoxins.
  • C-Reactive Protein (CRP): Laboratory tests measuring inflammatory markers, such as C-reactive protein (CRP) or cytokine levels, can assess the body’s inflammatory response to mold exposure. Elevated inflammatory markers may indicate ongoing inflammation and immune activation.
  • Neurological Testing: Neurological tests, including cognitive assessments, imaging studies (e.g., MRI or CT scans), and neurophysiological tests, can evaluate any neurological symptoms or complications associated with mold exposure. These tests can help identify changes in brain structure or function and guide treatment decisions.
