Overview

GI Select is a blend of ingredients like L-Glutamine, N-Acetyl D-Glucosamine, and various herbal extracts, aiming to support intestinal health. While each ingredient has some evidence of efficacy for gut health, the dosages may be lower than clinically studied. The combined effect of this specific formulation lacks extensive clinical validation.

The Good

Comprehensive Gut Support Formula: Combines amino acids, MSM, and herbal extracts.

L-Glutamine: Contains a clinically relevant dose of L-Glutamine, which supports intestinal cell proliferation and function.

Multiple Anti-Inflammatory Ingredients: Includes Quercetin, C3 Reduct, Aloe Vera, and Gutgard that may reduce gut inflammation.

The Bad

Relatively Low Dosing: Several ingredients appear at dosages lower than those used in some clinical trials.

Limited Clinical Evidence for Specific Combination: Studies generally examine individual ingredients, not this specific blend.

Potential Shellfish Allergen: Contains N-Acetyl D-Glucosamine which is derived from crustacean shellfish which may cause allergic reactions in sensitive individuals.
