nac precursor to glutathione N-acetylcysteine Clinical Applications Existing and potential therapeutic uses

Most side effects are mild and transient

Patch test recommended before regular use

Beyond telomeres, Epitalon is also thought to help regulate melatonin and serotonin production, reduce oxidative stress, and support immune function

Future research should focus on large-scale, well-controlled randomized trials with standardized dosing protocols, clearly defined deficiency thresholds, and long-term follow-up to strengthen the evidence base and guide clinical practice

Research efforts are also focused on understanding how variations in experimental design, concentration, and molecular stability may affect peptide behavior across different in vitro systems
