Free-Form L-Glutamine for Gut and Muscle Support
Glutamine is one of the amino acids your body leans on most. SFI Health (formerly Klaire Labs) describes it this way: "L-Glutamine is an amino acid that is the primary energy source for your intestinal cells and is widely present in muscle tissue."*
Who I Reach For This With
- Patients building a gut-support protocol who need a simple, single-ingredient amino acid

- Anyone whose plan calls for flexible dosing of 1 to 4 capsules a day between meals
What Makes This Form Different
- 500 mg of L-glutamine per capsule, in the free form
- Small capsule size makes it easy to scale the amount up or down

How It Fits Into a Protocol
L-glutamine is a foundation piece in many of my gut-support protocols. It pairs naturally with a broad probiotic like Ther-Biotic Complete, with RepairVite GT Plus for the gut lining, and with GI-Synergy when microbiome balance is the focus. I set the number of capsules by the patient and the plan.
