Under proper storage conditions, the solution remains stable throughout its labeled shelf life

Because of this, clinical settings often relied exclusively on intravenous (IV) glutathione or precursor amino acids to raise intracellular levels

It has been studied extensively in animal models for its ability to accelerate healing of tendons, ligaments, muscle, gut lining, and nerve tissue

Animal studies report biological activity after oral administration, especially in gastrointestinal models, which suggests potential local effectiveness

The biological rationale is interesting but unproven
