 It was great chatting with you the other day. I’ve put together this general overview, but as I mentioned, you’ll definitely want to do your own deeper research. This is a very complex, interactive environment, and you’ll naturally come across many different opinions about what’s happening. Most opinions tend to focus on single layers, but as I’ve discovered, these layers are highly interconnected and influence one another.

I don’t want to oversimplify things, nor do I want to overcomplicate them. It takes time to truly understand the gut environment in its proper context. I’m also cautious about saying “do X and you’ll get Y,” because results are rarely that straightforward. When I introduce layered therapies, I look for subtle changes across a list of markers I track. That’s why I believe this should be approached with care and patience—though I’m very optimistic about the research I’ve uncovered.As you know, it takes diligence to track these things down. There’s no one-size-fits-all solution or magic pill, and I appreciate that you’re already aware of this.
As I mentioned, much of the research points to the gut as the central pivot in many autoimmune conditions. This makes sense when you consider that roughly 70% of the immune system resides in the intestinal tract.The gut is composed of multiple layers that function in a specific order. While many people focus primarily on the microbiome as the key player, in autoimmune and especially severe autoimmune cases, the microbiome is really just the outer layer. It often reflects what’s happening in the deeper layers beneath it.Because the gut is a multi-factorial system, there is significant crosstalk between these layers. One important component is the mucin layer, which tends to become degraded in many people with gut issues. When this protective layer breaks down, the entire system becomes dysregulated.
Tight junction proteins are another critical element. These proteins are made up of specific amino acids and nutrients. They can begin to separate under stress from viruses, bacteria, toxins, or other triggers. This is one reason binders can be helpful—they protect the tight junctions not only from environmental toxins but also from metabolic toxins produced during immune stress. When toxins accumulate, they pull the tight junctions apart.I’ve experimented with several amino acids that support these structures. Glycine and threonine are particularly useful, as threonine also helps strengthen the mucin layer. Another valuable one is NAG (N-acetylglucosamine). For these proteins and amino acids to be properly assimilated and utilized, the body needs foundational nutrients such as vitamin B6, zinc, and others.
Since you’re still producing some saliva, that may indicate you still have some functional mucin layer remaining. In my case, it was badly damaged, which I could tell by the extremely dry mouth I experienced. Saliva production is closely tied to the mucin layer, which is similar to the one in the gut.
I’ve tried various layered approaches. For example, combining vitamin A, vitamin D, and colostrum is a solid, low-cost option. I’d approach it as a layered protocol and not stay on it indefinitely, though you could. In many cases, you may notice a difference within one to two weeks.
I would also consider adding bone broth or collagen peptides, which supply many of the key amino acids directly to the gut lining for tissue repair. Pairing these with the vitamin A, D, and colostrum combination can be very supportive. I’d also include the Life Force product I sent you, as it provides the baseline nutrients needed to properly convert and utilize the amino acids.
If there’s no noticeable improvement, a simple next step could be cassava flour (inexpensive) paired with unpasteurized kimchi or sauerkraut—such as Cleveland Kraut, which is widely available (including at Walmart) and contains live cultures. The cassava flour works with the probiotics to help produce short-chain fatty acids. It’s a straightforward, low-cost (~$10) approach.
Some people experience disruptions (such as histamine release) when taking certain probiotics. This is often a sign that the deeper gut layers are still compromised, causing the probiotics to trigger an immune response. In those cases, it’s better to focus first on repairing the underlying layers before adding probiotics. As with any protocol, it’s important to introduce things gradually at low doses so the body can acclimate. Over-stimulation can do more harm than good, so careful monitoring is essential.
Research also shows links between autoimmune diseases and whether someone was breastfed or bottle-fed. Key factors include the presence of Bifidobacterium (especially Bifidobacterium infantis), which is passed from mother to child, and human milk oligosaccharides (HMOs) that feed these beneficial bacteria. Bifidobacteria are considered master regulators of immune responses in the gut. Low levels are commonly seen in autoimmune conditions, along with reduced short-chain fatty acid production.Studies (including some from Duke University) have found dysregulated microbiomes and low bifidobacteria/short-chain fatty acids in autoimmune patients. What’s often missing from the discussion is that healthy bacteria can be diminished by high levels of reactive oxygen species (ROS) generated by ongoing immune activation. Antioxidants such as vitamin C can help protect these beneficial bacteria from oxidative stress.
Chronic ROS stress also promotes gut inflammation and biofilm formation. Biofilms are complex and can include oxidized lipids, aldehydes, fibrin, and other material—essentially creating a “sludge” environment. Some approaches, such as high-dose enzymes (e.g., nattokinase, serrapeptase) or bismuth protocols (like the one from Dr. Anderson that we discussed), have been used to address them. However, biofilms tend to resolve more effectively once the underlying tissue is healthier.When I focused on repairing the deeper layers—primarily through bone broth and selected polyphenols like turmeric—I noticed meaningful improvements, including better neurological function and reduced anxiety.
The topic gets quite complex, and I don’t want to overwhelm you. If I were in your position, I would start with the simple, low-cost vitamin A + vitamin D + colostrum combination, then layer in bone broth or collagen peptides. Monitor how you feel rather than staying on it for extended periods, as these can be quite active. Many people notice benefits within 1–2 weeks.
Finally, it’s worth researching the GALT system (gut-associated lymphoid tissue). The body often redirects energy resources (ATP) from muscles and other areas to support immune activity in the gut. This prioritization shows how central the gut is to overall health.

Paneth Cells - guardians of the intestinal tract

  Click for the AI slideshow: https://sl.bing.net/hBioK3sTdDw From Google Gemini: Paneth Cells: The Guardians of the Gut Paneth cells are specialized epithelial cells found at the base of the intestinal crypts (small invaginations in the intestinal lining). They play a crucial role in maintaining the gut's health by acting as a first line of defense against harmful microorganisms. Key Functions: Antimicrobial Defense: Paneth cells produce and secrete a variety of antimicrobial peptides and proteins, such as lysozyme, defensins, and phospholipase A2. These substances help to kill bacteria, fungi, and other pathogens that may invade the intestinal tract. Regeneration of Intestinal Epithelium: Paneth cells contribute to the maintenance and regeneration of the intestinal lining by supporting the stem cells located nearby. Immune Regulation: These cells participate in regulating the immune response within the gut, helping to balance the body's reaction to both beneficial and ha...
You can buy most of this at Kroger's, I listed the pictures below. The idea is that you are targeting the gut, the microbiome to be exact. I am not going to list out all the studies but they have discovered that the right bacteria in the gut can change a lot of things including metabolic, neurological, immune responses, weight gain and many other things.  Increasing the good bacteria such as bifidobacteria etc. can also suppress the bad bacteria which have been linked to numerous problems.  There are products that you can buy on Amazon and these will also support the microbiome by giving the nutrients they need.  Kroger's has the ones in the pictures below, you will find the Cleveland Kraut in the refrigerated section and so is the Kefir. Both of these are live foods meaning they contain the good bacteria. Sauerkraut as canned does not work since there are no live organisms.  You will have to experiment with the doses; I do a couple of tablespoons of the kraut and ju...

 Educational only: Keep in mind that the system is really a networked system meaning that one system, say neurology can impact other systems such as endocrine, immunity etc. The gut contains 70% of the immune system and when immunity is triggered, it can seep into other systems, particularly the neurological. The gut/brain axis is well established and now they know that many neuropsychiatric conditions have origins the gut. Examples of this are Parkinson's disease or Autism, but also more common problems like depression, anxiety etc. There are several explanations that I will not go into but primarily, it is the immune responses that are occurring within the gut mostly due to a gut whose microbiome is out of balance.  Sleeping issues can be a telltale sign of some immune triggering, insomnia is one of those which in my case is due to histamine release, that is why anti-histamines tend to help me fall asleep. Histamine is a byproduct of immune activation.  The gut/brain ax...
