Glutathione is the liver's primary tool for neutralizing toxins, so providing it in a liposomal form can help maintain the liver's protective capacity
Apart from TRPC channels, a role for ionotropic glutamate receptors for Ca 2+ entry has been suggested: NMDA receptors permeable to Ca 2+ accomplish Ca 2+ homeostasis [102, 103], and also AMPA receptors may be relevant as pharmacological AMPA receptor antagonism blunts Ca 2+ entry into erythrocytes in response to Cl - removal [104]
If your glutathione levels are low, you might observe discolorations or patches that just weren't there before
Drugs enter the body orally, are absorbed through the gastrointestinal tract, enter the liver through the portal vein, and some drugs may be metabolized by the liver or bind with plasma proteins before entering the systemic circulation and ultimately reaching the eyes
