Table 2 Effect of low protein diet with and without supplemental folate on erythrocyte and liver glutathione in rats

From: Preovulatory exposure to a protein-restricted diet disrupts amino acid kinetics and alters mitochondrial structure and function in the rat oocyte and is partially rescued by folic acid
