Having a way to measure brain ageing with a home test kit from a pin prick of blood, means we can realistically see what the impact of specific diet changes and antioxidant supplements might be

In a 2020 review, the researchers corroborated that silymarin's capacity to reduce oxidative stress on the liver could indeed improve biomarkers associated with conditions such as alcoholic fatty liver disease, nonalcoholic fatty liver disease, alcoholic cirrhosis, and drug-induced liver injury.29 Although the studies covered in the review used 420mg silymarin doses, others have found that amounts as low as 200mg could also impart the desired effects on liver health.30 If that weren't all, a 2018 study concluded that silymarin may actually increase glutathione levels in the liver.31 Selenium (55mcg) Selenium is an essential mineral with antioxidant properties, and one that may increase levels of an enzyme called glutathione peroxidase (GPx).32 GPx is important because it uses reduced glutathione to neutralize hydrogen peroxide,33 one of the major ROS

Individuals with certain gene variants may have a more challenging time eliminating these metals, making glutathione support crucial for recovery
Also, there is lack of literature evaluating its efficacy.[] IV administered GSH is not directly utilized by cells but is cleaved into its component amino acids and is resynthesized to GSH intracellularly after transmembrane transport
