This allows for potentially more glutathione to enter the brain where it is most needed

This master antioxidant works quietly behind the scenes to reduce oxidative damage to brain cells, support healthy neurotransmitter function, and protect against the processes that lead to cognitive decline

Cul3-mediated Nrf2 ubiquitination and antioxidant response element (ARE) activation are dependent on the partial molar volume at position 151 of Keap1

This means that it reaches your bloodstream and cells

these enzymes promote hydrogen peroxide metabolism and protect cell membrane structure and function from oxidative damage
