These cells did not grow in medium without any glutathione (0 M) but they grew in media with very small amounts of glutathione (i.e., more than 0.25 M of extracellular glutathione)
For example, in a study at John Hopkins University , forty boys and young men, ages 13 to 27, with moderate to severe autism, were treated for 18 weeks with a daily dose of either a placebo or sulforaphane, a plant chemical derived from broccoli sprouts

These tree-like nanostructures improve peptide penetration through cell membranes
You can bolster your glutathione levels even more by including glutathione-rich foods in your diet and with glutathione precursors like n-acetyl-cysteine, selenium, and alpha lipoic acid
