The gut is not just a digestive organ. It produces neurotransmitters, regulates immune function, and communicates directly with the brain. When gut health is compromised, the effects extend far beyond digestion. Bloating, fatigue, brain fog, immune dysfunction, and mood instability are all commonly linked to gut lining integrity and intestinal inflammation. Peptide therapy offers a class of compounds that address these mechanisms directly.
How peptides support gut health
The key mechanisms are gut lining repair and inflammation reduction. The intestinal epithelium (the single-cell layer lining your gut) depends on tight junctions between cells to maintain its barrier function. When these junctions become compromised, the condition commonly described as "leaky gut" allows inflammatory compounds to pass into the bloodstream. Certain compounds directly support the repair of these tight junctions and reduce inflammation in the gut lining.
Compounds available through Tides
The compounds below are available through the Tides platform. BPC-157, which is the most commonly discussed compound for gut healing, is expected to be available in late 2026 pending FDA approval. In the meantime, patients interested in BPC-157 can flag it during their assessment and their physician will advise accordingly.
BPC-157 (discuss with your physician)
BPC-157 is the most studied compound for gut healing. Originally studied for its gastric protective properties, it has shown strong effects on intestinal repair, inflammation reduction, and gut motility. For gut health specifically, oral administration is often preferred because it delivers the compound directly to the gut lining. BPC-157 is not currently in Tides' standard lineup but is worth discussing with your physician during your assessment.
Glutathione for gut oxidative stress
The gut is highly vulnerable to oxidative stress, which contributes to inflammation and impaired barrier function. Glutathione is the body's primary antioxidant and is produced in significant quantities in intestinal cells. Injectable glutathione supports antioxidant defense in the gut, reduces oxidative damage, and may support overall gut resilience. It is available through Tides as a physician-prescribed protocol.
NAD+ and gut cellular energy
Intestinal cells have very high energy demands. NAD+ supports cellular energy production in these cells and may support the repair processes that maintain gut integrity. It is not a primary gut therapy but is sometimes included in broader wellness protocols for people dealing with chronic gut dysfunction and fatigue.
Methylene Blue and gut oxidative stress
Methylene Blue supports mitochondrial function and reduces oxidative stress at the cellular level. Chronic gut inflammation generates significant oxidative burden, and compounds that address this can support the overall environment for gut repair. It is not a primary gut therapy but may be relevant for people with significant systemic inflammation alongside their gut symptoms. Available through Tides as a physician-prescribed protocol.
Good to know: Gut health is highly individual. What drives dysfunction varies significantly between people, including stress, diet, medications, infections, and genetics. A physician evaluation helps identify the most appropriate approach for your specific situation.
Approaches to gut health support
| Approach | Mechanism | Best for |
|---|---|---|
| BPC-157 oral (discuss with physician) | Tight junction repair and inflammation | Leaky gut, IBD, IBS, GI motility |
| Glutathione injectable (Tides) | Antioxidant defense and cellular protection | Oxidative stress, systemic inflammation |
| NAD+ injectable (Tides) | Cellular energy support | Fatigue alongside gut dysfunction |
| Methylene Blue (Tides) | Mitochondrial support and oxidative stress reduction | Systemic inflammation alongside gut symptoms |
| Dietary and lifestyle changes | Foundational gut support | Everyone, as the base of all approaches |
How to get started through Tides
Start with an online health assessment covering your health history, symptoms, and goals. Takes about five minutes. If you want to discuss BPC-157 specifically, note this during your assessment.
A licensed physician reviews your assessment the same day and determines which compounds are clinically appropriate for your situation. Prescriptions are filled at a licensed U.S. compounding pharmacy.
Your medication ships to your door within five to seven business days. Your physician is available for check-ins throughout your protocol. Cancel or adjust anytime.
Realistic expectations
Gut healing is not immediate. Most people notice reduced bloating and improved digestive comfort within two to four weeks of starting an appropriate protocol. More significant improvements in gut lining integrity and systemic inflammation typically take six to twelve weeks. Chronic gut conditions that have been present for years may require several months of consistent treatment. Always work with a physician and disclose all medications and supplements. Lifestyle factors including diet and stress management remain foundational to gut health outcomes.
