Thats likely to be because studies show peak absorption of N-Acetylcysteine - a precursor to glutathione - is 4560 minutes
Researches suggest that morning doses offer antioxidant protection throughout the day while evening works for correction

If you have a specific injury or gut issue that hasn't resolved with standard treatment, it's worth discussing with a provider who works with peptides
In the BHMT pathway, Hcy uses betaine as a methyl donor, ultimately producing methionine and dimethylglycine (DMG)
