In people

When people raise their glutathione, blood and red-cell glutathione climb within two weeks and keep rising over a month. Oxidative stress markers fall, and natural killer cell activity and lymphocyte growth rise. People describe clearer skin, more even tone, better energy and easier recovery after alcohol or a hard week. Those with a heavy toxin or oxidative load, from diabetes, alcohol, smoking or chronic illness, notice the most change. Injection skips the gut, where much of a swallowed dose is broken down.
