This research showed that GSH supplementation of amino acids (including L-glycine) and micronutrients (including vitamin C, vitamin E, and magnesium), as well as specific dietary patterns (vegetarian, the Mediterranean diet, and the DASH diet) had the potential to raise glutathione concentrations, which in turn slowed the rate of tissue deterioration

Age-related decline in glutathione synthesis contributes to changes in cognitive function, making supplementation particularly valuable for older adults seeking to support mental acuity [5]
Also, if you are taking any medications or have underlying health conditions, it's important to consult with a healthcare professional before starting glutathione supplements to ensure there are no potential interactions
