Gut Protection With L-Glutamine

When you have a digestive illness, it essentially means that your delicate intestinal lining (the mucosa) is damaged, making it impossible to extract nutrients and other substances crucial for your body’s biological processes. The amino acid L-Glutamine is one of these substances. A protein building block, L-Glutamine is stored in muscle where it’s vital to tissue growth and repair. It’s involved in the formation of other amino acids and glucose (sugar), as well as the body’s adaptive response to stress and the optimal functioning of the immune and digestive system.The mucosa requires maintenance to protect and repair itself from the effects of stress, toxins, and a poor diet. When the mucosa breaks down, inflammation results and this is associated with a variety of chronic health conditions. Further, when illness, chronic or severe stress, inflammation, or food sensitivity/allergies cause the gut to fail at effectively breaking down food to acquire nutrients, deficiency results. A lack of sufficient glutamine in the gut creates a cycle of wear and tear on the mucosa.Clinical research shows that L-Glutamine supplements can break that cycle by helping repair damage and potentially help the lining regrow. This connection between glutamine and intestinal maintenance has led researchers to examine its role in Celiac Disease and gluten sensitivity.L-Glutamine supplements are available in both pill and powder form. Proper dose is crucial to its effectiveness. It’s not recommended for children under age ten or for people with certain health conditions, including kidney or liver disease. Consult with your holistic health practitioner to find out if L-Glutamine is right for you.REFERENCES

Lyme disease shares key symptoms with fibromyalgia, multiple sclerosis, and chronic fatigue syndrome, so it can be mistaken for any of them. It is also over-diagnosed in people who do have one of those conditions. The honest answer is that Lyme is worth confirming or ruling out with a knowledgeable clinician, not assumed in either direction.

Most people leave a Hashimoto's diagnosis with a prescription and no explanation for why it started. You are told your immune system is attacking your thyroid, and that you will likely take levothyroxine for life. What you are rarely told is why this started now, when other people carry the same risk genes and never get sick.

Scientists at MIT engineered mice that fight off Lyme and pass that protection to their pups. In a 2026 study, ticks that fed on these mice picked up almost no Lyme. It is a real step toward fewer infected ticks, but it does little for anyone who already has it.
