Binding agents are an integral part of mycotoxin illness detoxification. Trying to decide which binder is correct for which mycotoxin can be a difficult process. This blog provides a collection of research connecting mycotoxins to a good binder choice.

When it comes to mycotoxin binding research, we must keep in mind the toxic nature of these toxins. Their toxicity makes the research limited to animals, animal feed, and in vitro studies. Due to the unethical nature of purposefully exposing humans to mycotoxins, there is limited research on these binders in humans. This is acceptable as the binding capacity can still be evaluated efficiently. In your journey to understanding how our bodies process mycotoxins, it is crucial to understand their metabolism.

After a positive Organic Acids Test and MycoTOX Profile, the presence of mould and mycotoxins are usually significant answers for many symptomatic clients. When working with mycotoxicosis, choosing the correct binder can present a challenge. Oftentimes I get the question: which binder is correct for which toxin? Since the research for the binding capacity of each binder isn’t as heavily researched as other agents, it can be daunting to sift through the information. Below is a collection of research connecting mycotoxins to a good binder choice.

In our bodies, toxins are detoxed and excreted through a few pathways. Routes of elimination include urine, stool, bile, and through our skin. Other routes include tears and saliva but are negligible in the realm of detoxification. Another route is breast milk. Since breast milk is a route of excretion this means toxins can be transferred to another life this way. This fact makes binders even that much more crucial in childbearing-age women.

When it comes to binders, bile and stool are the target routes of elimination. Fat-soluble substances such as dietary lipids, certain vitamins, and fat-soluble toxins like mycotoxins get packaged into bile for absorption and detoxification. During bile’s lifecycle, it gets excreted into the GI tract and is what gives stool its brown colour. In the colon, most of the bile is reabsorbed so the liver and gallbladder do not have to work as hard to make more bile. It is recycled and reused. Dysfunction of this phenomenon, bile acid malabsorption and chronic diarrhea are the main symptoms. Since bile is reabsorbed, in the ileum and jejunum, if toxins are packaged in the bile then the toxins can be reabsorbed as well. They would then re-enter circulation via the hepatic portal system. This is where binders come in handy. Binders will adhere to the bile that packages the toxins and then it cannot be reabsorbed. Due to the nature of this adherence, it cannot be trusted that the bond is irreversible. This bond is more like a static cling, as described by Dr Neil Nathan. The lack of a tight bond allows for the bile to be released if not excreted regularly. This means that irregular bowel movements from constipation, lack of fibre, or motility issues could cause the resorption of toxins even with binder usage. Binders by nature are constipating and this should be mitigated and assessed regularly during binder usage. Properly moving bowels through diet and supplements should be achieved before adding any binding agent. 

    Peach Stone

This next adsorbent option is one I had not initially thought about. It’s peach stone. The pit of a peach has a composition of biological polymers like cellulose, lignin, and hemicellulose. These compounds increase the intensity of the hydroxyl and phenol groups which give it the adsorbing quality6. Additionally, the substantial structure of the peach stone, with all its openings and canals, also makes for a larger surface area for binding sites. By studying both modified and unmodified peach stone (MPS/PS) we know that this binder can bind Aflatoxin B1, Ochratoxin A (OTA), Deoxynivalenol (DON), Zearalenone (ZON), Diacetoxyscirpenol (DAS) and T-2 toxin. Both MPS and PS, close to a physiologic pH of 7.0, had specific affinities to each toxin6. PS had a higher binding capacity for Aflatoxin B1 than MPS, while both had equal binding capacity to Ochratoxin and T-2 toxin. MPS had a higher affinity for DON, ZON, and DAS as compared to PS6. Overall, the MPS higher the most consistent binding affinity and would be a good overall binder for multiple toxin elevations.

Micro Chitosan

Micro chitosan is another commonly used product. It is a polysaccharide from the outer shell of shellfish like crab and shrimp. It is traditionally used in drug and medicine manufacturing13. As of late, it has been studied as a binding agent in poultry and in corn and wheat crops to reduce mycotoxins. One study showed that chitosan binds Fusarium toxins, fumonisins, and DON, in corn and wheat products14. Another revealed in a poultry gastrointestinal model, that chitosan has a wide binding capacity. In this study chitosan bound to, in increasing order, AFB1, FB1, FB2, OTA, AFG2, AFG1, ZEA, and AFB22,4. Another study also linked chitosan as a good adsorbent to trichothecenes11. Not many binders have been linked to trichothecenes, so this is a benefit to clients who are unfortunately exposed to these. As a side note goji berries have been linked with charcoal as a winning pair in binding and decreasing the toxic effects of T2 toxin10. With micro chitosan take caution and avoid use in anyone who has a shellfish allergy.
