L-Glutathione (GSH) 98% – 100 Caps x 400 mg – Antioxidant


+ Minimal Shipping

L-Glutathione (GSH) 98% contains a tripeptide that functions as strong antioxidant and prevents damage to cells due to reactive oxygen.


L-Glutathione (GSH) 98% is a polypeptide composed of the three amino acids glutamic acid, cysteine and glycine. The substance is ubiquitous as it’s naturally found in all cells of the body. It is an effective antioxidant that prevents damage to important cellular components caused by reactive oxygen, such as free radicals and peroxides.

Thiol groups are reducing agents, existing at a concentration of approximately 5 mM in animal cells. The l-glutathione supplement reduces disulfide bonds formed within cytoplasmic proteins to cysteines by serving as an electron donor. In the process, it is converted to its oxidized form disulfide (GSSG), which is better known as glutathione.

The supplement is found almost exclusively in its reduced form, since the enzyme that reverts it from its oxidized form, glutathione reductase, is constitutively active and inducible upon oxidative stress. In fact, the ratio of reduced form to the oxidized form within cells is often used as a measure of cellular toxicity.


As is a powerful antioxidant GSH neutralizes free radicals in the body. Free radicals are reactive molecules that can cause oxidative stress, leading to cellular damage. The antioxidant activity is crucial for protecting cells from oxidative damage, supporting overall cellular health.

Cellular Repair

L-glutathione is involved in cellular repair mechanisms and DNA synthesis. It helps repair damaged cells and maintain the integrity of genetic material. This role is critical for preventing mutations and supporting overall cellular health.


The antioxidant properties of GSH extend to cardiovascular health. It helps protect blood vessels from oxidative damage, supports proper blood vessel function, and may contribute to lower blood pressure. These effects contribute to overall heart health and reduce the risk of cardiovascular diseases.


Glutathione has anti-inflammatory properties that help modulate inflammatory responses in the body. Chronic inflammation is linked to various health conditions, including cardiovascular diseases, arthritis, and neurodegenerative disorders. The anti-inflammatory effects contribute to overall health and may reduce the risk of inflammatory diseases.


The compound is involved in energy production at the cellular level. By supporting mitochondrial function, it may contribute to increased energy levels and overall vitality.


L-glutathione 98% GSH is present in high concentrations in the brain, where it plays a crucial role in protecting nerve cells from oxidative stress. It has been studied for its potential neuroprotective effects, making it relevant in the prevention or management of neurodegenerative diseases.

Immune System

GSH is essential for a well-functioning immune system. It helps modulate immune responses, enhances the activity of immune cells, and contributes to the body’s defense against infections and diseases. Adequate levels are crucial for optimal immune function.


L-Glutathione plays a central role in the body’s detoxification processes. It binds to and helps eliminate toxins, heavy metals, and other harmful substances. By supporting the liver and enhancing detoxification pathways, it contributes to the body’s ability to eliminate potentially harmful compounds.

Youthful Skin

L-glutathione is often associated with skin health and anti-aging. It helps combat oxidative stress in the skin, which contributes to a more youthful appearance. Some people use the supplement for skin lightening.


Glutathione supplement has been studied for its role in respiratory health. It may help protect the lungs from oxidative damage and inflammation, making it of interest in managing respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Chronic Conditions

Some chronic conditions, such as autoimmune issues and certain neurodegenerative disorders, are associated with low glutathione levels. Supplementing with l-glutathione may provide support for individuals dealing with these conditions, although the specific benefits varies.
