THORNE Leaky Gut Support, formerly known as EnteroMend, is a scientifically formulated gut health supplement designed for individuals seeking to maintain a healthy intestinal barrier. It is particularly beneficial for athletes and active individuals who experience GI discomfort during training, as well as anyone dealing with symptoms of 'leaky gut' syndrome.
The standout feature of this product is its unique combination of L-glutamine, a key amino acid for gut lining repair, with well-studied botanicals like aloe vera, curcumin, and boswellia. Together, these ingredients help soothe irritated mucous membranes, reduce inflammation, and support overall digestive function, making it a comprehensive solution rather than a single-ingredient approach.
THORNE has built a solid reputation as the #1 most recommended clinical brand by healthcare practitioners, and Leaky Gut Support lives up to that standard. The powder mixes easily in water, has a pleasant orange vanilla flavor, and is NSF Certified for Sport, meaning it is free from nearly 300 banned substances and meets rigorous label accuracy standards.
One potential drawback is the price, which is higher than basic L-glutamine powders. Additionally, the orange vanilla flavor, while nice, may not be for everyone, and the 30-serving container means you will need to repurchase monthly if using daily. However, for those serious about their gut health and willing to invest, these are minor trade-offs.
Overall, THORNE Leaky Gut Support is an excellent choice for athletes, fitness enthusiasts, and anyone with digestive sensitivity. Its evidence-based formula, third-party certification, and trusted brand reputation make it a standout product in the gut health category, despite its higher cost.
