Little known, glutathione is undoubtedly the most powerful antioxidant in the body. It has many roles within it, both on vital organs and in the prevention of chronic diseases. Nutrimuscle reveals everything there is to know about this amino acid.

What is glutathione?
Glutathione is a powerfulantioxidant . It is composed of 3 amino acids: L-cysteine, glycine and L-glutamate.
It works in synergy with other antioxidants (vitamin C, vitamin E, etc.) to protect the body from free radicals. The latter constitute unstable molecules produced in response to external aggressions (pollution, stress, alcohol, poor diet). They are factors in the development of chronic diseases and degeneration of the body.Indeed , their presence releases oxidative stress which damages cellular DNA, proteins and lipids. Taking glutathione helps prevent these inconveniences.
Where is glutathione found?
Glutathione and its three amino acids are present in the body and in food.
The body can synthesize glutathione and certain organs contain more than others: this is the case of the liver, lungs, kidneys, brain and intestines.
In the diet, we find glutathione in rich foods such as:
Here are some foods that can promote glutathione production:
- Garlic and onions: These vegetables contain cysteine, an amino acid component of glutathione.
- Cruciferous vegetables: Rich in sulfur, these vegetables are responsible for the production of glutathione.
- Leafy green vegetables: They contain glutamine, the other amino acid necessary for the synthesis of glutathione.
- Avocados: They contain glutathione precursors, making them an excellent food for supporting the levels of this antioxidant in the body.
Although the body is able to synthesize glutathione, the body produces less and less as it ages. It is therefore essential to consume it through food or food supplements, in its active form: L-glutathione.
The benefits of glutathione
Glutathione acts on all physical and cognitive functions. Its benefits are numerous and concern many areas: cells, the digestive system, the brain system, mental health, the immune system, eye health, respiratory tract, bone health, but also addiction and addiction problems. 'infertility. Here are some examples of the benefits of glutathione:
Powerful powerful antioxidant : On the front line against free radicals, glutathione protects cells from oxidative stress. In fact, glutathione rebalances cells that have become free radicals by providing them with an electron.
Immune system support: Glutathione supports white blood cells and destroys invading pathogens. In addition, it regulates the phenomenon of inflammation. Glutathione supports the immune system and speeds recovery.
Detoxification of the liver : The main action of the liver is to detoxify the body. Glutathione is essential for allowing the liver to eliminate toxic substances, such as heavy metals. Glutathione acts on chemical residues by making them soluble in water, thus facilitating their elimination through natural channels (bile, urine).
Protection against chronic diseases: Glutathione protects the body from chronic diseases, particularly cardiovascular and pulmonary. A glutathione deficiency increases the risk of type II diabetes.
Discussions are ongoing regarding the effects of glutathione on the skin. Although it is used in East Asian countries to lighten the complexion, it has harmful effects on melanin production.
Glutathione deficiencies
Although glutathione is synthesized by the body, it is possible to develop a deficiency over time. Indeed, as previously mentioned, glutathione stocks decrease as we age.
Several factors can lead to glutathione deficiency. First of all, we find external aggressions such as a polluted environment, stress, an unbalanced diet, alcohol and tobacco consumption. In short, the free radicals caused by these factors multiply. If glutathione reserves are too low, they can no longer neutralize free radicals.
Therefore, glutathione deficiency weakens the immune system, increases vulnerability to infections, worsens oxidative stress, and increases the risk of chronic diseases. You should therefore not wait until you have a deficiency to supplement with glutathione.
It is therefore recommended to vary your diet and enrich it with green vegetables to ensure a sufficient intake of this antioxidant. In this way, glutathione detoxifies and protects the body from numerous external attacks.
