Summary

This trial will investigate whether glutathione (GSH) precursors N-acetylcysteine and glycine can help improve cognition in humans with mild cognitive impairment.

Who is the study for?
This trial is for older adults with mild cognitive impairment, which is an early stage of memory loss. Participants should not have been hospitalized recently, have diabetes, severe kidney or liver disease, a history of stroke or heart issues, or untreated depression.
What is being tested?
The study explores if taking supplements N-acetylcysteine and glycine can improve cognition by increasing antioxidant levels in the brain. Participants will be compared to those taking alanine over a period of 12 weeks and then observed for another 12 weeks after stopping the supplements.
What are the potential side effects?
Potential side effects from N-acetylcysteine may include nausea, vomiting, rash or headache. Glycine could cause light-headedness and gastrointestinal discomfort. Alanine is generally considered safe but may also lead to stomach upset.

2Treatment groups
Active Control
Placebo Group
Group I: MCI-activeActive Control2 Interventions
30 Subjects with MCI will receive N-acetylcysteine and glycine for 12-weeks. ll subjects will be studied at baseline prior to supplementation, after completing 12-weeks of supplementation, and 12-weeks after stopping supplementation (i.e. at 24-weeks). Supplements are only provided for first 12-weeks.
Group II: MCI-placeboPlacebo Group1 Intervention
30 subjects will received alanine for 12-weeks. All subjects will be studied at baseline prior to supplementation, after completing 12-weeks of supplementation, and 12-weeks after stopping supplementation (i.e. at 24-weeks). Supplements are only provided for first 12-weeks
