Whats more, the studies we do have suggest that some injectable peptides could trigger abnormal immune system responses, leading to allergic reactions (including severe ones like anaphylaxis) or autoimmune issues in some people

Glutathiones main roles include: Neutralizing harmful free radicals Acting as a cofactor for several antioxidant enzymes Regenerating vitamins C and E Neutralizing free radicals produced by Phase I liver metabolism of chemical toxins, including formaldehyde, acetaminophen, benzpyrene, and many other compounds Participating in Phase I and Phase II detoxification reactions Adhering to toxins and heavy metals (including mercury) before carrying them out of the body Regulating cellular proliferation and apoptosis Participating in mitochondrial function and the maintenance of mitochondrial DNA Essentially, glutathione is crucial for shielding cells from endogenous and exogenous reactive oxygen and nitrogen species, as well as dealing directly with the causes of oxidative stress such as mercury and pollutants

Potential limitations of this study include the short duration, modest sample size, use of a home EEG headband rather than in-lab polysomnography, baseline dietary differences, lack of change on some sleep-related assessment scales, and industry involvement by the extract manufacturer
