Biochemical basics
Glutathione is a tripeptide of glutamic acid, cysteine and glycine, which occurs in two forms: reduced glutathione (GSH) and oxidized glutathione (GSSG). The synthesis of GSH is crucial for cell health and detoxification. GSH acts as an antioxidant and plays a role in neutralizing free radicals. An imbalance between GSH and GSSG can lead to oxidative stress. A balanced ratio of these two forms supports cell repair and function, protects against chronic disease and promotes overall health.
The function of glutathione
Glutathione fulfills a variety of functions that make it a central component of the human body: It acts as a powerful antioxidant and protects cells from damage caused by free radicals. Through its effect on glutathione levels, it contributes to the regulation of oxidative stress in the body. High glutathione levels are crucial for health as they help the body to reduce inflammation and repair cells. Maintaining optimal glutathione levels at all times is important to ensure the full effect of this essential molecule.
Neutralization of free radicals
Free radicals are unstable molecules that can lead to oxidative stress in the cells and thus endanger health. This is where glutathione (GSH) comes into play, acting as a powerful antioxidant by neutralizing free radicals. This neutralization protects cell structures and maintains their functionality. Various factors, such as environmental stress and lifestyle, can affect GSH levels, leading to reduced energy production in the cell. A balanced intake of nutrients can help to support glutathione production.
Support for detoxification
The liver is the main organ for detoxification, and glutathione plays a key role in this. It binds toxins such as heavy metals, environmental toxins and drug breakdown products and promotes their elimination. However, a lack of glutathione can impair the body's ability to detoxify and increase stress, resulting in low glutathione levels. This deficiency can also increase the risk of chronic disease. Ensuring that glutathione levels in the body are adequate is part of general health care and can be achieved through diet or supplements.
Strengthening the immune system
Glutathione (also known as GSH) plays a crucial role in strengthening the immune system. This tripeptide, which consists of glutamic acid, cysteine and glycine, acts as an antioxidant and protects cells from oxidative damage. Sufficient GSH levels are necessary for immune cells such as T cells and natural killer cells to work effectively. Vitamin C helps to restore GSSG, the oxidized form of glutathione, to its reduced form, thus keeping glutathione levels in balance. This strengthens the body's immune system and successfully fends off infections.
Cell repair
Glutathione plays a crucial role in cell repair. Following oxidative stress or damage from toxins, glutathione supports cell repair by promoting protein synthesis and DNA repair. It helps to revitalize damaged cells and aims to maintain or restore cell structure. Glutathione's ability to reduce oxidative damage protects the cell from further damage. Its effect is therefore essential for maintaining healthy cell functions. Effective cell repair processes by glutathione can strengthen the health of cells in the long term.
Why is glutathione important for health?
A stable glutathione level is crucial to protect the body from disease and premature ageing. A deficiency of glutathione can lead to a variety of health problems. Glutathione, also known as GSH, plays an essential role in protecting against oxidative stress. Low glutathione levels can be further exacerbated by excessive stress and a lack of key nutrients such as vitamin C. To maintain and optimize glutathione levels in the body, one should ensure a balanced diet rich in antioxidants as well as supporting minerals.
Oxidative stress and ageing
Oxidative stress occurs when the balance between free radicals and antioxidants is disturbed, which can cause cellular damage. Glutathione plays a crucial role in protecting cells from oxidative stress. Without sufficient glutathione, cells are more susceptible to damage, which can accelerate the ageing process. This stress also increases the risk of diseases such as cardiovascular disease and diabetes. An effective defense against oxidative stress therefore has a crucial impact on health and quality of life by helping to protect cells and slow down aging.
Chronic diseases
Glutathione deficiency is associated with a number of diseases, including Alzheimer's, Parkinson's, cancer and autoimmune diseases. In such diseases, the ratio of GSH to GSSG is crucial, as a low GSH level indicates a deficiency. A lack of GSH can lead to oxidative stress, which favors the development and worsening of chronic diseases. You can find out more about this in our article on the role of glutathione in chronic diseases. The optimal balance between GSH and GSSG is important to protect the body from chronic stress and promote health.
Protection from environmental pollution
Daily factors such as air pollution, pesticides and heavy metals put the body under stress. Glutathione, an essential component of cellular defense, is a tripeptide that helps neutralize these pollutants and minimize their toxic effects. Adequate glutathione levels in the body are crucial to ensure protection from these environmental stressors. A glutathione deficiency can therefore impair the body's ability to counteract these stressors, which can lead to increased susceptibility to health problems.
How can you increase glutathione levels?
To improve glutathione levels, the body's own synthesis should be supported. This includes a balanced diet with foods such as broccoli and spinach, which are rich in precursors for glutathione synthesis. Regular exercise and stress management can also have a positive effect on glutathione levels. Food supplements such as N-acetylcysteine or alpha-lipoic acid also have an effect by acting as precursors to promote synthesis. Overall, the combination of lifestyle and targeted use of supplements helps to effectively increase glutathione levels.
Nutrition
A balanced diet is crucial for supporting glutathione production. Certain foods are particularly effective. Fruit and vegetables rich in vitamin C, such as oranges and peppers, contribute to the regeneration of glutathione. Watermelon and tomatoes are also beneficial as they have antioxidant properties. Recommended foods also include spinach because of its nutrient-rich composition. A regular intake of such foods can have a positive effect on glutathione levels and contribute to overall health.
Food supplements
Products to support GSH levels are widely available. N-acetylcysteine (NAC) provides a precursor to cysteine and directly supports glutathione production. Packaged as liposomal glutathione, some products offer high bioavailability. In addition, the intake of alpha-lipoic acid promotes the regeneration of glutathione.

The difference between natural and supplemented glutathione
Glutathione, often referred to as GSH, is a key antioxidant in the body. It exists in two forms: the reduced form GSH and the oxidized form GSSG. A balance between the two is important for optimal cell protection. Unlike other nutrients, such as vitamin C, which the body cannot produce itself, it synthesizes glutathione itself, although factors such as stress can impair production. This is where supplemented sources of glutathione come into play, which can help to balance requirements, but should not completely replace natural sources.
Studies and scientific background
Numerous studies have shed light on the role of glutathione in cell health. The synthesis of this molecule is crucial as it is present in its oxidized form, GSSG. A lack of glutathione can lead to various health problems. This deficiency also affects glutathione levels in the body, which in turn can increase susceptibility to oxidative damage. Scientific research has shown that low glutathione levels are often associated with chronic diseases, which underlines the importance of this tripeptide for human well-being.
Glutathione and oxidative stress
A high glutathione level can help reduce oxidative stress, as glutathione neutralizes reactive oxygen species. This makes it an important component in the fight against cell damage caused by oxidative stress. Studies show that foods rich in vitamin C can support glutathione production. In addition, glutathione is often described as essential for protecting the body from the negative effects of environmental pollution and oxidative stress. Regular consumption of certain foods can therefore help to regulate glutathione levels and reduce stress.
Glutathione deficiency and diseases
A meta-analysis found that glutathione levels were significantly lower in patients with Alzheimer's disease than in healthy individuals. The deficiency of GSH (glutathione, often abbreviated as GSH) could be an important factor. Such a deficiency has been associated with various diseases, including neurodegenerative diseases. The importance of GSH in the prevention of these diseases emphasizes the need to maintain GSH levels. In fact, glutathione deficiency can increase susceptibility to oxidative stress and other health burdens, so it is important to promote understanding about GSH and its benefits.
