Leaky gut and chronic inflammation are locked in a cycle. Tarsul’s MSM sulfur breaks this cycle by reducing gut inflammation and providing the building blocks for gut barrier repair, while potassium supports the anti-inflammatory gut microbiome.
Leaky gut and chronic inflammation are locked in a vicious cycle. Gut inflammation breaks down the gut barrier, allowing inflammatory compounds to enter the bloodstream. These compounds trigger systemic inflammation throughout the body. That systemic inflammation feeds back into the gut, causing more gut inflammation and more barrier breakdown. Breaking this cycle requires addressing both the gut inflammation and the gut barrier simultaneously.
The Inflammation-Leaky Gut Cycle
Gut inflammation damages the tight junctions that seal the gut barrier. When tight junctions break down, bacterial fragments (LPS) and other inflammatory compounds enter the bloodstream. Your immune system responds with systemic inflammation — elevated cytokines, activated immune cells, increased oxidative stress.
This systemic inflammation doesn’t stay in the bloodstream. It feeds back into the gut, activating gut immune cells and causing more gut inflammation. More gut inflammation means more barrier breakdown. More barrier breakdown means more LPS in the bloodstream. The cycle continues until something breaks it.
How Tarsul Breaks the Cycle
MSM sulfur is one of the most effective natural anti-inflammatory compounds available. It reduces the production of pro-inflammatory cytokines (particularly TNF-alpha, IL-6, and IL-1beta) that drive both gut inflammation and systemic inflammation. By reducing gut inflammation, it allows the gut barrier to repair itself.
At the same time, MSM sulfur provides the building blocks for tight junction proteins, supporting the structural repair of the gut barrier. The potassium in Tarsul supports the gut microbiome, which produces anti-inflammatory short-chain fatty acids that further reduce gut inflammation. The combination addresses both sides of the inflammation-leaky gut cycle.
Reducing Systemic Inflammation
As the gut heals and becomes less permeable, the LPS burden in the bloodstream decreases, and systemic inflammation begins to resolve. This is why people healing leaky gut often notice improvements in symptoms far removed from the gut — joint pain, skin problems, fatigue, brain fog — as the systemic inflammation that was driving these symptoms decreases.

When the gut barrier breaks down, bacterial fragments (LPS) enter the bloodstream and trigger systemic immune activation, producing chronic inflammation throughout the body.
Yes. MSM sulfur reduces the production of pro-inflammatory cytokines (TNF-alpha, IL-6, IL-1beta) and supports glutathione production, which is a key regulator of inflammatory response.
Initial reduction in gut inflammation typically occurs within 4 to 6 weeks. Significant decrease in systemic inflammation usually follows the gut healing timeline of 3 to 6 months.
Reduced bloating, improved energy, clearer thinking, less joint pain, improved skin, and better tolerance of previously reactive foods are all signs that leaky gut inflammation is resolving.
