How Glyphosate Disrupts the Gut Microbiome

Glyphosate is a widely used herbicide that can disrupt the gut microbiome by inhibiting the shikimate pathway in bacteria, which many beneficial gut microbes rely on to produce essential amino acids. This may reduce microbial diversity and suppress protective strains, creating an imbalance that favors opportunistic organisms. Research also suggests glyphosate may impair glutathione activity, the body’s master antioxidant, by increasing oxidative stress and interfering with sulfur metabolism, which is critical for glutathione production. As oxidative stress rises and beneficial bacteria decline, the intestinal barrier can weaken. Tight junction proteins that seal the gut lining may become compromised, contributing to increased intestinal permeability, often referred to as leaky gut, which allows endotoxins and inflammatory compounds to pass into circulation and potentially trigger systemic inflammation.

The Role of MSM in Counteracting Oxidative Stress

MSM, or methylsulfonylmethane, is a bioavailable organic sulfur compound that serves as a critical building block for many processes in the body. Sulfur is essential for producing glutathione, the body’s master antioxidant, as well as for forming strong connective tissues, healthy keratin for hair and nails, and maintaining the structural integrity of the gut lining. Because glyphosate is believed to interfere with sulfur metabolism and increase oxidative stress, it may indirectly deplete glutathione and weaken the intestinal barrier. MSM helps counteract this by replenishing sulfur pools needed to synthesize glutathione, supporting detoxification pathways, and reducing inflammatory signaling.

MSM and Gut Barrier Protection

In the gut specifically, adequate sulfur supports tight junction proteins that seal the intestinal lining. By helping restore glutathione levels and lowering oxidative stress, MSM may protect the integrity of the gut barrier and reduce the risk of increased intestinal permeability, commonly called leaky gut. Maintaining strong glutathione levels is vital for stellar health because glutathione neutralizes free radicals, supports liver detoxification, regulates immune responses, and protects mitochondria, the energy engines of your cells. In short, MSM supplies the foundational sulfur your body needs to defend, repair, and maintain resilience from the inside out.

Understanding the Difference Between MSM and Glutathione

MSM and glutathione are related, but they play different roles in the body.

Glutathione is your body’s master antioxidant. It is a small molecule made from three amino acids, glutamine, glycine, and cysteine, and is responsible for neutralizing free radicals, recycling other antioxidants like vitamins C and E, supporting liver detoxification, regulating immune function, and protecting mitochondria. The challenge is that oral glutathione can be poorly absorbed and rapidly broken down in the digestive tract unless taken in liposomal or specialized forms, and its levels fluctuate quickly depending on stress, toxins, illness, and inflammation.

MSM, on the other hand, is a stable, bioavailable sulfur compound. Sulfur is required to make cysteine, which is the rate limiting amino acid in glutathione production. Instead of supplying glutathione directly, MSM supports your body’s ability to produce and maintain its own glutathione levels. It also contributes sulfur for connective tissue repair, keratin formation, joint integrity, and maintenance of tight junctions in the gut lining. In addition, MSM has its own anti inflammatory and antioxidant properties.

The Key Functional Difference

Glutathione is the finished antioxidant molecule.

MSM is a foundational sulfur donor that helps your body build glutathione and repair tissues long term.

Why Is MSM Considered More Superior For Leaky Gut?

MSM is considered more sustainable because it supports the upstream machinery your body uses to make glutathione rather than temporarily supplying the finished molecule. Glutathione levels are constantly turning over. They rise and fall depending on stress, toxins, inflammation, sleep, and nutrient status. When you take glutathione directly, even in liposomal forms, you may increase circulating levels for a period of time, but if your body lacks sulfur or cysteine, it cannot maintain production on its own. MSM helps replenish sulfur pools that are required to continuously synthesize glutathione, repair leaky gut and tissues, and maintain structural proteins like keratin and collagen. In that sense, it supports the system rather than simply topping off the tank.

Should You Take Both?

YES. They work differently and can be complementary. Glutathione, especially liposomal or acetylated forms, may be helpful during periods of acute oxidative stress, toxin exposure, illness, or high inflammation when you want a more immediate antioxidant effect. MSM works more gradually, supporting long term detox capacity, connective tissue repair, and gut integrity.

Which Has More Impact on Leaky Gut?

For structural gut support, MSM may have a broader effect because sulfur is needed for tight junction protein integrity, mucosal barrier strength, collagen and connective tissue in the gut lining, and ongoing glutathione production inside intestinal cells.

Glutathione helps reduce oxidative stress in the gut lining and calm inflammation, which is important, but it does not directly provide the structural building blocks. If the goal is reinforcing the gut barrier over time, MSM may play a more foundational role, while glutathione can help manage the oxidative and inflammatory side of permeability.

I formulated holi (radiance) MSM & ceramides for gut integrity, glutathione support and skin partially for this reason. MSM is like collagen in that it should be taken every day. The benefits of MSM are immeasurable - joint health, liver health, repairing leaky gut. On top of all of that it  brightens your skin and is often called a beauty mineral for its effect on your hair and nails. In clinical studies it ENHANCES the effects of collagen and it makes it work even better.
