Also known as GSH, it is produced in the liver and nerve cells of the central nervous system and consists of three amino acids: glycine, L-cysteine, and L-glutamate

If your goal involves gastrointestinal healing, the peptide contacting intestinal tissues directly could provide benefit even if it never reaches the bloodstream
Notably, high doses of Vitamin B (folic acid 0.8 mg, Vitamin B6 20 mg, Vitamin B12 0.5 mg) for 2 years was shown to slow the progression of brain atrophy significantly (Donnelly et al., 2008)
The incidence of chromosomal aberrations in the bone marrow of SAMP-1 mice with accelerated aging appeared almost twice as high as in the other two models
