This finding reveals a new mechanism through which hydrogen exerts neuroprotective effects indirectly via the stomach-brain axis

Glutathione depletion is particularly linked to neurodegenerative disorders, pulmonary diseases, immune disorders, cardiovascular diseases, and chronic geriatric conditions [50]

However, as with any supplement that impacts internal chemistry, questions about safetyspecifically regarding the kidneysare common

High-quality whey protein is particularly powerful because it's loaded with cysteine - often the bottleneck amino acid in glutathione production

Since they show a range of redox reactions, their mechanism of action in vivo may not be related to an antioxidant effect
