Researchers may misinterpret this as high inter-subject variability or weak efficacy when the real cause is compromised sample integrity
Effects on skeletal muscle fibers, amino acid uptake, and protein synthesis IGF-1 LR3 has been shown to have a variety of effects on skeletal muscle fibers, including increased size and number of myofibrils (the contractile units within muscle cells), as well as improved sarcomere organization (the structural units within myofibrils)
Glutathione is a naturally occurring antioxidant made from three amino acids

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
