Liver detoxification pathways and supportive nutrients. You should always work backwards when trying to support the phases of detoxification - pushing phase 1 before the other phases are working optimally can cause an exacerbation of symptoms due to inflammation.

I spoke with Jacie and Barbara about the first step of any CIRS/mould illness protocol - getting out of exposure. We spoke about testing, remediation and the difficulties in finding suitable housing.

If your VCS test and symptom cluster analysis are positive, then you might want to do a mycotoxin urine analysis to measure the amount of mycotoxin you're excreting. You can use either the Real Time or Great Plains labs, but my preference is Real Time because provocation (glutathione + sweating) usually prevents false negatives.

Here's an example from a teenage girl who was exposed to mould in a water damaged building. The second test is after 6 months of CIRS treatment with significant reduction of symptoms. She still has a long way to go but her mycotoxin levels are decreasing.

Here I explain how chronic inflammation can cause autoimmune conditions via a genetic predisposition, an environmental trigger, and leaky gut.

If you have 8 or more positive symptom clusters, the next step is to complete a Visual Contrast Sensitivity (VCS) test. Visual contrast sensitivity testing measures your ability to see details at low contrast levels and is often used as a nonspecific test of neurological function, which commonly declines in CIRS patients. The VCS test has a 92% accuracy rate based on data collected from tens of thousands of tests taken over the years since Dr. Shoemaker first began using it.

Below is an example of a client's VCS results while being exposed to mould (fail) and then after CIRS treatment with full resolution of symptoms (pass).

If you're concerned about mould illness/CIRS, the first step is to complete a symptom cluster analysis. This table represents research by Dr Ritchie Shoemaker, who found that 37 common symptoms could be categorised into 13 clusters. His clinical research suggests that if an adult possesses eight or more clusters of symptoms, the likelihood of CIRS exceeds 95%.

In my clinic the five most common CIRS symptoms are fatigue, difficulty concentrating, decreased assimilation of knowledge, memory impairment and mood swings. You can access the free symptom cluster analysis at https://bit.ly/mould-symptoms

Functional nutrition is never one-size-fits-all, instead it is a highly customized holistic health perspective that takes an individual's unique specifications into account. Functional nutrition follows a systems approach that takes into consideration how interrelated every part of the body is, looking at the big picture of health by restoring optimal physiological functioning. While standard healthcare will try to suppress symptoms with medication, functional nutrition instead sees them as clues for understanding the underlying issues within the body.
