The Cusack Protocol

The Cusack Protocol is a supplement-based regimen developed by Deborah Cusack for people with Ehlers-Danlos Syndrome (EDS) and related connective tissue disorders. It focuses on improving connective tissue integrity and function through a combination of supplements targeting specific cells involved in collagen production and tissue repair. While anecdotal reports suggest positive outcomes for some individuals following the Cusack Protocol, it is important to note that the protocol lacks clinical validation through large-scale studies. Before attempting any treatment protocol or diet, you should consult with your doctor. Below is an in-depth look at the core components and concepts behind the Cusack Protocol.

What is the Cusack Protocol?

Key Supplements in the Cusack Protocol

1. Polysaccharides (Aloe Vera or Maitake Mushroom)
   These polysaccharides target fibroblasts, which are essential for the production of connective tissue collagen. Aloe Vera and Maitake are believed to improve the integrity of ligaments, tendons, and vascular structures, including veins, arteries, and the heart. They also support areas like the dura (the brain's protective membrane) and ligaments in the spine. Symptoms addressed by this supplement include:
   • Joint hypermobility and pain
   • POTS (Postural Orthostatic Tachycardia Syndrome)
   • Cranio-cervical instability and headaches
   • Scoliosis and spinal issues
   • Easy bruising and slow wound healing​.
2. Probiotics (Lactobacillus rhamnosus GG - L-GG)
   Probiotics help regulate mast cells, which play a crucial role in immune system function. L-GG is suggested to improve gastrointestinal symptoms and food intolerances common in EDS by supporting gut health. It also helps reduce the permeability of the blood-brain barrier, potentially alleviating cognitive symptoms like brain fog. This supplement addresses:
   • Mast cell disease (MCAS)
   • Gastrointestinal hyperpermeability (leaky gut)
   • Food intolerances, frequent illness, and allergies​.
3. Pyrroloquinoline Quinone (PQQ)
   PQQ promotes mitochondrial health, which enhances energy production. It also improves the lining of the gastrointestinal tract and bladder, addressing issues such as gastroparesis (delayed stomach emptying), bladder dysfunction, and frequent infections. PQQ also targets cognitive function by promoting clarity and memory improvements​.
4. L-Arginine (Low Dose)
   This amino acid enhances the production of nitric oxide, improving blood flow and oxygen delivery. L-Arginine is essential for the health of endothelial cells, which line the blood vessels. This supplement can improve energy levels, cognitive function, and reduce vascular-related symptoms such as vascular insufficiency and fatigue​​.
5. Lion’s Mane (Hericium Erinaceus Mushroom)
   Lion’s Mane is a neuroprotective supplement that promotes the production of myelin, which insulates nerve cells. It targets the central nervous system, reducing stress and improving cognitive functions like memory and concentration. It may also help alleviate symptoms related to ADHD, OCD, and sensory processing issues​.
6. Diatomaceous Earth (Food Grade)
   This powdered form of fossilized algae is believed to detoxify the body by removing heavy metals, parasites, and other pathogens. Diatomaceous Earth also supports joint health by improving the lining of the gastrointestinal tract and reducing inflammation. It helps manage arthritis pain and degenerative joint diseases​.
7. Glucosamine Chondroitin
   A well-known supplement for joint health, Glucosamine Chondroitin promotes the regeneration of cartilage and dentin (the tissue beneath tooth enamel). It is commonly used to reduce joint pain, improve mobility, and slow the progression of joint degeneration. In this protocol, it also helps with tooth decay and fractures​.

The Healing Curve (Healing Crisis)

When starting the Cusack Protocol, users may experience what Cusack refers to as a "healing curve" or "healing crisis." This phase is characterized by a temporary worsening of symptoms as the body detoxifies and begins the process of tissue regeneration. Common symptoms during this period may include:

• Joint stiffness and muscle aches
• Fatigue, mild fever, headaches, and nausea

The healing curve can last anywhere from a few days to several weeks, depending on the individual. Cusack advises that it is crucial to regulate mast cells before starting the protocol to minimize these effects. Supplements like Lactobacillus rhamnosus and PQQ are suggested to help with this regulation​​.

Targeting Multiple Body Systems

The Cusack Protocol is designed not only to improve connective tissue but also to address secondary conditions often seen in EDS, such as:

• Vascular System: Supporting vein and artery health to manage conditions like POTS, pulmonary hypertension, and heart valve dysfunction.
• Musculoskeletal System: Reducing symptoms like scoliosis, spinal instability, and joint dislocations.
• Neurological Function: Enhancing cognitive function and reducing symptoms like brain fog, anxiety, and sensory issues through supplements like PQQ and Lion’s Mane.

Considerations and Safety

While anecdotal reports suggest positive outcomes for some individuals following the Cusack Protocol, it is important to note that the protocol lacks clinical validation through large-scale studies. As with any supplement regimen, potential interactions with medications or other treatments should be carefully considered. The protocol is not intended as a cure for EDS but rather as a long-term management strategy. Users are advised to consult with healthcare professionals before starting the regimen to ensure it aligns with their individual health needs and circumstances.

Scientific Theories Supporting the Cusack Protocol

Although the Cusack Protocol is not yet backed by clinical trials, some scientific studies provide theoretical support for its focus on improving collagen production and connective tissue health. These studies, while not directly proving the protocol’s efficacy, present hypotheses about how certain components of the protocol, such as Aloe polysaccharides, may contribute to connective tissue regeneration.

1. Aloe Vera Polysaccharides and Fibroblast ProliferationA key component of the Cusack Protocol, Aloe polysaccharides, have been studied for their role in promoting fibroblast proliferation, a type of cell responsible for producing collagen. Research has shown that Aloe polysaccharides can enhance the secretion of hyaluronic acid and hydroxyproline, two critical substances involved in skin and connective tissue health. One study found that treating fibroblasts with Aloe polysaccharides led to increased collagen synthesis and improved cell proliferation, both of which are essential for tissue repair and regeneration . This suggests that Aloe may help strengthen the connective tissue matrix, supporting the protocol’s goal of regenerating damaged tissues in EDS.
2. Collagen Production and Wound HealingAnother study on Aloe vera's impact on wound healing in rats demonstrated that it increased collagen content in healing wounds. Specifically, the research indicated that Aloe vera enhanced the cross-linking of collagen fibers, contributing to stronger and more resilient tissue. Additionally, the study found that Aloe vera promoted the production of type III collagen, which is typically found in early-stage wound healing, before being replaced by type I collagen. This could explain how Aloe vera in the Cusack Protocol supports not only superficial wound healing but also internal connective tissue repair .
3. Aloe Vera and Epithelial Cell ProliferationAloe vera's benefits extend to epithelial cells, which are responsible for lining various organs and tissues, including the skin, blood vessels, and digestive tract. A study on human epithelial cells treated with Aloe polysaccharides found that the substance promoted cell proliferation, allowing these cells to regenerate faster. This mechanism may be crucial for individuals with EDS, as weakened epithelial linings in the digestive system and vascular system are common issues. The findings suggest that Aloe vera could help improve the integrity of these tissues, aligning with the protocol’s goal of addressing symptoms like gastroparesis and vascular dysfunction .
4. Mitochondrial Support and Cellular EnergyOne of the central supplements in the Cusack Protocol, Pyrroloquinoline Quinone (PQQ), has also been linked to improvements in mitochondrial function. Mitochondria are known as the powerhouses of the cell, responsible for energy production. Studies suggest that PQQ can enhance mitochondrial biogenesis (the creation of new mitochondria) and improve cellular energy output. This mechanism could be particularly beneficial for individuals with EDS who suffer from chronic fatigue and muscle weakness, providing an additional layer of support through improved cellular energy and function .

While these studies provide theoretical support for the effects of some components of the Cusack Protocol, such as Aloe vera and PQQ, it is important to emphasize that these findings are still hypotheses. They offer potential explanations for how the protocol could improve collagen production and connective tissue health, but clinical validation is needed to fully confirm these effects. Until then, individuals considering the Cusack Protocol should consult with healthcare professionals and proceed with caution.

What Is the Cusack Protocol Used For?

The Cusack Protocol is proposed to help manage a wide range of symptoms associated with Ehlers-Danlos Syndrome (EDS) and other connective tissue disorders. These conditions often lead to a variety of issues related to joint instability, chronic pain, vascular problems, and digestive dysfunction. While EDS is the primary focus, the protocol may also benefit individuals with related conditions affecting connective tissue health. Below are some of the key areas that the Cusack Protocol aims to address:

1. Joint Hypermobility and Pain
   Many individuals with EDS experience joint hypermobility, where joints move beyond their normal range, leading to dislocations, subluxations (partial dislocations), and chronic pain. The supplements in the Cusack Protocol, such as glucosamine chondroitin and Aloe polysaccharides, are believed to support collagen production and improve joint stability, potentially reducing pain and the frequency of joint dislocations.
2. Vascular Issues
   EDS can affect the integrity of blood vessels, leading to conditions like Postural Orthostatic Tachycardia Syndrome (POTS), which causes lightheadedness, rapid heart rate, and fatigue upon standing. The protocol, particularly through supplements like L-Arginine, aims to strengthen the vascular system by improving endothelial function, enhancing blood flow, and supporting the overall health of blood vessels.
3. Gastrointestinal Dysfunction
   Many people with EDS suffer from gastroparesis (delayed stomach emptying), leaky gut syndrome, and general digestive issues. The Aloe polysaccharides and probiotics in the protocol are designed to improve the health of the gastrointestinal lining, regulate mast cells, and support the body’s ability to absorb nutrients. These elements can potentially help with symptoms like bloating, nausea, and food intolerances.
4. Chronic Fatigue
   Fatigue is a common symptom in people with EDS, often due to mitochondrial dysfunction or energy deficits in cells. The inclusion of PQQ in the protocol is aimed at improving mitochondrial function, which can enhance energy production and reduce symptoms of chronic fatigue and muscle weakness.
5. Cognitive Function (Brain Fog)
   Many EDS patients report experiencing brain fog, which includes issues with memory, concentration, and mental clarity. The Lion’s Mane mushroom and PQQ in the Cusack Protocol target cognitive function by promoting nerve growth and mitochondrial health, potentially improving mental clarity and reducing fatigue-related cognitive issues.
6. Mast Cell Activation Syndrome (MCAS)
   Mast cell disorders, like MCAS, are commonly associated with EDS. These disorders involve the overactivation of mast cells, leading to allergic reactions, inflammation, and a range of symptoms like rashes, hives, and gastrointestinal problems. The protocol includes supplements like Lactobacillus rhamnosus and PQQ, which may help regulate mast cells and reduce histamine-related symptoms.
7. Wound Healing and Skin Integrity
   People with EDS often experience poor wound healing, easy bruising, and fragile skin due to connective tissue defects. Aloe vera, a key component of the Cusack Protocol, has been studied for its potential to promote fibroblast proliferation and enhance collagen production, which could aid in better wound healing and improve skin integrity.

The Cusack Protocol is proposed to treat a variety of symptoms related to connective tissue dysfunction, including joint instability, vascular and digestive issues, chronic fatigue, and cognitive impairments. By targeting the underlying collagen and connective tissue deficits, the protocol aims to support tissue regeneration and provide relief from many of the debilitating symptoms experienced by individuals with EDS and related disorders. However, it is essential to consult with a healthcare provider before beginning this or any supplement regimen.

Conclusion

The Cusack Protocol offers a unique, supplement-based approach to managing symptoms associated with EDS and connective tissue disorders. By focusing on collagen production and supporting various body systems, it aims to improve quality of life for individuals dealing with joint instability, vascular issues, and chronic fatigue. While the protocol has garnered support from some patients, its efficacy remains largely anecdotal, and more research is needed to fully understand its potential benefits and risks.
