glutathione research study Liposomal outperforms plain glutathione in uptake, cell regeneration and systemic availability: evidence from cellular and human models | British Journal of Nutrition Glutathione 1500mg | ≥99% Purity
Description
It has been shown to reduce the neurotoxicity caused by 6-OHDA in SH-SY5Y cells and to get rid of free radicals, which suggests it could be used to treat Parkinsons disease (Silva et al., 2016)

In our opinion, the COPD study (Campbell et al.) is the most representative in this aspect, because not only were the gene signatures derived from areas with histologically confirmed pathology, but also GHKs effects on affected lung tissue were tested in vitro and their correlation to gene effects was well-established [37]
