The Bottom Line If you are wondering how long will glutathione take effect, the most honest answer is that it works gradually
In a study published in the American Journal of Clinical Nutrition , researchers gave healthy adults 500mg of vitamin C daily and measured a rise in red blood cell glutathione of nearly 50% within two weeks, compared with baseline (Johnston et al., 1993)
Note that strong chelators, phosphate-rich buffers and reducing agents in an experimental medium will compete for the copper centre and alter the species actually present
Notice subtle shifts in skin tone, hydration, and vitality rather than expecting dramatic results in 2 weeks
