Review: Quality product - Product works and is high quality. Other brands that I have used up to this point haven't worked as well. You can actually tell it digests and can feel the results. It also dosnt have as overwhelming tast when mixed. Also no bad smell or taste. It is on the pricy side but in this situation I would say you get what you pay for.
Review: Essential for gut and immune health – pure, clean, and effective - I’ve been using THORNE L-Glutamine Powder for several months now, and it’s become a staple in my wellness routine. This supplement is designed to support gastrointestinal (GI) health, immune function, and muscle recovery. Each serving provides 5 grams of pure L-glutamine, an amino acid that plays a crucial role in maintaining the integrity of the intestinal lining and supporting immune cells. Key Benefits: • GI Health: L-glutamine serves as fuel for enterocytes, the cells lining the intestines, promoting a healthy gut barrier. • Immune Support: It aids in the function of immune cells, helping the body respond to stress and illness. • Muscle Recovery: Supports muscle repair and recovery post-exercise or injury. Product Features: • Unflavored Powder: Mixes easily with water or other beverages without altering taste. • Free From Common Allergens: No gluten, soy, dairy, or artificial additives. • NSF Certified for Sport®: Ensures the product is free from banned substances, making it safe for athletes. Usage Tips: I typically mix one scoop with 8 ounces of water in the morning on an empty stomach. It’s also effective post-workout for muscle recovery. Consistency is key; regular use has noticeably improved my digestive comfort and overall energy levels. Considerations: While this product is excellent for supporting gut and immune health, it’s essential to consult with a healthcare professional before starting any new supplement, especially if you have underlying health conditions. #ThorneSupplements #LGlutamine #GutHealth #ImmuneSupport #MuscleRecovery #NSFCertified #CleanSupplements #WellnessRoutine

### ⭐⭐⭐⭐⭐ My digestion feels like absolutely nothing - Perfect!
*by M***C on August 17, 2025*

This product is helping me more than any other supplement I've tried for my food intolerances. If you know, you know. Dissolves easily in a few ounces of water and has essentially no taste or texture. No residue left in the bottom of the glass. I bought it because Thorne is known for quality products but I may try another brand next time as the cost is very high in comparison. For now I consider it money well spent while dealing with acute issues.
