L-Glutathione – the expert formula for natural beauty and energy
L-Glutathione is the body’s most powerful protector against aging, toxins and oxidative stress. It supports the liver and detoxification, boosts immunity, protects cells and contributes to brighter and younger looking skin. Glutathione supports mitochondrial redox balance, protects neurons from oxidative damage and the body’s overall protection from free radicals.
With age, L-Glutathione levels drop, and this accelerates fatigue and aging. Its support tangibly supports longevity.

The Benefits of Taking L-Glutathione
Long-term use of Glutathione at doses of 250 mg and 1,000 mg daily, for a period of 6 months results in an increase in body levels of Glutathione. These results support the use of oral Glutathione as an effective strategy to increase tissue depots.
The observed increase in glutathione levels is both dose-dependent and time-dependent, with the most pronounced effect observed in participants taking 1,000 mg daily.
The increase was observed in the complete blood count, red blood cells, plasma, and lymphocytes, indicating a generalized effect on the various components of the blood. After discontinuing use, glutathione levels gradually return to baseline values, which further confirms the link between its use as a dietary supplement and the observed changes.
These data are consistent with the results of experimental studies in animals, which demonstrate the existence of a specific intestinal transport system for glutathione.

Although the exact mechanism behind the increase in levels is not fully understood, the results suggest that long-term use may affect metabolism and lead to higher and more stable concentrations in the body.
A significant reduction in oxidative stress was found. In healthy volunteers with low baseline levels of oxidative stress, this effect was moderate but clinically significant.1
What does the study say about L-glutathione?
This clinical study changes the long-held belief that oral Glutathione cannot effectively raise levels in the human body. The data clearly show that with prolonged intake
Glutathione is not only absorbed but also leads to a sustained increase in its levels in various blood and immune cells.
The higher the dose and the longer the duration of use, the more pronounced the effect, which underscores the importance of time as a key factor in the biological action of glutathione.
Of particular importance is the observed improvement in redox balance, as measured by a decrease in the ratio of oxidized to reduced glutathione. This suggests a potential protective role against chronic oxidative stress, even in healthy individuals with low baseline levels of oxidative stress.
At the same time, there are indications of a potential benefit for the immune system, manifested in increased activity of NK cells, which play a key role in the antitumor and antiviral immune response.
The combination of efficacy, good tolerability, and the absence of side effects positions oral glutathione as a promising tool for maintaining cellular protection and immune homeostasis.
The results of this study not only fill an important gap in the clinical data on glutathione, but also open up new avenues for future research into conditions associated with glutathione deficiency and increased oxidative stress.
