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.

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 was both dose-dependent and time-dependent, with the most pronounced effect found in participants taking 1,000 mg daily. The increase was recorded in complete blood count, erythrocytes, plasma and lymphocytes, indicating a generalized effect on the different blood components. After cessation of intake, Glutathione levels gradually returned to baseline values, further confirming the relationship between its use as a dietary supplement and the changes observed.

These data are consistent with results from experimental studies in animals demonstrating a specific intestinal transport system for Glutathione. Although the exact mechanism of the increase in levels is not fully understood, the results suggest that long-term intake may affect metabolism and result in higher and 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

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 leads to a steady increase in its body depots in various blood and immune cells. The higher the dose and the longer the period of intake, the more pronounced the effect, highlighting the importance of time as a key factor in the biological action of Glutathione.

Particularly important was the observed improvement in redox balance, as measured by a decrease in the ratio between oxidized and reduced Glutathione. This points to a potential protective role against chronic oxidative stress, even in healthy individuals with low baseline levels of oxidative stress. In parallel, a possible benefit to the immune system also emerged, as expressed by increased activity of NK cells, which play a key role in the antitumor and antiviral immune response.

The combination of effectiveness, good tolerability and lack of adverse 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 new avenues for future studies in conditions associated with Glutathione deficiency and increased oxidative stress.
