Peptides Glutathione 1500mg CAS：70-18-8

**Glutathione (GSH)** is an important antioxidant peptide that is widely present in all living cells, especially in the liver. It is composed of three amino acids: **glutamic acid**, **cysteine** and **glycine**. Glutathione plays an important role in antioxidant defense, detoxification, metabolism and immune response in cells.

### **Physical and chemical properties:**

- **Chemical structure**: The molecular formula of glutathione is **C10H17N3O6S**, and the molecular weight is 307.3 Da. It is composed of amino acids **glutamic acid**, **cysteine** and **glycine** bonded by peptide bonds. Glutamic acid is bonded to cysteine ​​by a γ-peptide bond, while cysteine ​​and glycine are bonded by an α-peptide bond.

- **Solubility**: Glutathione is water-soluble and can be easily dissolved in water, but has poor solubility in organic solvents. Due to its polar amino acid side chains, glutathione has strong solubility in aqueous environments.

- **Stability**: Glutathione is an easily oxidized compound that is easily oxidized to **glutathione disulfide (GSSG)** when exposed to air, which leads to the loss of its antioxidant capacity. Therefore, its storage needs to avoid oxygen and high temperature environments.

### **Biological functions:**

1. **Antioxidant effect**: Glutathione is one of the most important reduced antioxidants in cells, which can neutralize free radicals (such as hydrogen peroxide, superoxide anions, etc.) and reactive oxygen species (ROS) to protect cells from oxidative damage.

2. **Detoxification effect**: Glutathione helps detoxification by forming soluble complexes with toxic substances. It combines with certain harmful substances (such as heavy metals, drug metabolites) to form water-soluble complexes and promote their excretion.

3. **Maintaining the intracellular reducing environment**: Glutathione helps maintain the reduction-oxidation balance (red oxygen balance) of cells, and generates **glutathione disulfide (GSSG)** through reactions, which can then be restored to reduced glutathione by glutathione reductase.

4. **Immune System Support**: Glutathione also plays an important role in the immune system, promoting the function and response of white blood cells, especially in antiviral and antibacterial responses.

### **Dosage and Use:**

Glutathione is commonly used in health care and clinical treatment, and its dosage varies depending on the purpose. Here are some common dosage and usage recommendations:

1. **Oral Dosage**:

- Conventional supplement dosage is generally **250-500 mg/day**, used to enhance antioxidant capacity, support liver detoxification function or enhance the immune system.

- In some special health problems, the dosage can be increased to **1000 mg/day**, but it should be done under the guidance of a professional doctor.

2. **Intravenous/Intramuscular Injection**:

- In clinical practice, glutathione can be supplemented by injection, especially in the treatment of critically ill patients or after acute toxic exposure. The common intravenous dosage is **600-1200 mg/day**, and is adjusted according to the patient's condition.

### **Half-life and pharmacokinetics:**

Glutathione is metabolized very quickly in the body, usually metabolized and excreted by the liver. Its half-life is relatively short, usually between **4-6 hours**, and the specific time is affected by multiple factors such as individual differences, dosage, and usage.

- **Oral**: Since glutathione is a water-soluble small molecule, it is absorbed into the blood through the gastrointestinal tract after oral intake. However, oral supplementation of glutathione may be affected by gastrointestinal degradation, and its bioavailability is low.

- **Injection**: Glutathione in the form of intravenous injection has a high bioavailability and can quickly enter the blood circulation and exert its effect.

### **Cycle and Effect:**

- **Acute Effect**: Intravenous glutathione usually takes effect within a few hours, quickly reduces oxidative stress in the body, reduces inflammatory response, and helps improve clinical symptoms. Especially when treating poisoning caused by drugs or chemicals, the effect is particularly obvious.

- **Chronic effects**: Long-term oral administration of glutathione as an antioxidant supplement can gradually improve the antioxidant capacity of cells, support the immune system, slow down the aging process, and promote liver function.

- Long-term use helps slow down the aging process, improve skin health, and improve fatigue resistance.

### **Side effects and risks:**

- **Fewer side effects**: Glutathione is considered safe, especially when used at appropriate doses. In a few cases, oral or injection administration may cause mild gastrointestinal discomfort (such as nausea, bloating).

- **Overdose risk**: Overdose may cause the body's reduction-oxidation balance to be disturbed, especially long-term high-dose use may affect the metabolism of other antioxidant substances in the body.

- **Allergic reactions**: In rare cases, individual users may have an allergic reaction to glutathione, manifested as rash, difficulty breathing and other symptoms.

### **Summary:**

Glutathione is an important antioxidant peptide, widely used in clinical detoxification, anti-aging, and immune function enhancement. Its short half-life requires frequent replenishment, but its antioxidant, detoxifying and immune-supporting effects in the body make it valuable in the nutraceutical and therapeutic fields. Appropriate use of glutathione can help improve overall health, especially in environments with high antioxidant stress.

**Glutathione** is a tripeptide composed of amino acids - glutamic acid, cysteine ​​and glycine, which is widely present in every cell of the human body, especially in the liver. It is considered to be a powerful antioxidant that can help remove free radicals and harmful substances in the body, thereby protecting cells from oxidative damage. In addition, Glutathione is closely related to multiple physiological processes such as detoxification, immune support, and cell metabolism.

### **Applicable population**

Glutathione supplementation is usually suitable for the following groups of people:

1. **Anti-aging population**: As age increases, the level of Glutathione in the body will gradually decrease, so supplementing Glutathione can help anti-aging and slow down the aging process of the skin.

2. **People with low immunity**: Since Glutathione is involved in the generation and function of immune cells, proper supplementation can enhance the immune system's ability to resist disease.

3. **People with impaired liver function**: Glutathione plays an important role in the liver's detoxification process, especially for people who drink alcohol for a long time, abuse drugs or suffer from liver diseases (such as fatty liver, hepatitis, etc.). Supplementing Glutathione can help restore liver function and promote liver self-repair.

4. **People with heavy environmental pollution or exposure to toxic substances**: People who are exposed to toxic substances such as air pollution, industrial pollution, tobacco smoke, heavy metals, etc. for a long time, Glutathione can help remove toxins and heavy metals in the body and alleviate environmental toxicity.

5. **People with skin problems**: Glutathione is believed to have the effect of whitening and fading spots. Some people use it for skin beautification and brightening, especially those who want to improve uneven skin color, freckles, yellowness and other skin problems.

6. **Athletes or people who often perform strenuous exercise**: During exercise, the body will produce a large number of free radicals. Supplementing Glutathione can help reduce free radical damage, promote muscle recovery, and reduce fatigue after exercise.

### **How ​​it works**

The main mechanisms of action of Glutathione include:

1. **Antioxidant effect**: Glutathione is one of the most important antioxidants in the human body. It can neutralize free radicals and peroxides in the body and reduce the damage to cells caused by oxidative stress. It can "reduce" these free radicals by providing hydrogen atoms to react with free radicals, thereby reducing the risk of cell damage.

2. **Detoxification function**: Glutathione plays an important detoxification role in the liver, converting fat-soluble toxins into water-soluble substances, which are then excreted from the body through urine or bile. In addition, Glutathione is also involved in the detoxification process of heavy metals (such as mercury, lead, etc.) and certain drugs.

3. **Immunomodulation**: Glutathione enhances immune response by supporting the function of T cells and other immune cells in the immune system. It helps maintain the health of cells and promotes resistance to pathogens.

4. **Repair damage**: Glutathione also plays an important role in cell DNA repair and anti-cell aging, helping to delay the cell aging process and reduce the occurrence of chronic diseases.

5. **Improve skin pigmentation**: Glutathione can inhibit the activity of tyrosinase, thereby reducing the production of melanin and achieving a whitening effect.

### **Usage and Dosage**

There are many ways to supplement Glutathione, including oral, intravenous, and topical application. Different methods of administration have different absorption effects and uses. The following are common oral supplementation recommendations:

1. **Oral**:

- **Dosage form**: Common oral forms of Glutathione include tablets, capsules, powders, liquids, etc.

- **Dosage**: The recommended dose for adults is usually 100 to 300 mg per day, but the specific dose varies according to individual needs, health status, and other factors.

- **Time**: Oral Glutathione can be taken after meals to reduce the risk of stomach discomfort.

2. **Intravenous injection**:

- In some clinical treatments, especially for liver diseases, heavy metal poisoning, etc., Glutathione may be given by intravenous injection. This method directly enters the blood system and has a faster absorption effect, but it usually needs to be used under the guidance of a doctor.

3. **Topical application**:

- Glutathione is added to some skin care products because of its whitening effect. Through topical products, Glutathione can be absorbed by the skin, thereby helping to reduce spots and even out skin tone.

### **Precautions**

**Glutathione (GSH)** is a tripeptide that occurs naturally in the body and is composed of the amino acids glutamic acid, cysteine, and glycine. It is considered one of the most important antioxidants in the body and is widely present in cells, especially in the liver. The main function of glutathione in the body is to protect cells from damage by free radicals and harmful substances. It also participates in multiple physiological processes such as cell detoxification and immune function. Its benefits cover many aspects. The following is a detailed introduction to the benefits of glutathione.

### 1. **Strong antioxidant effect**

One of the main functions of glutathione is to act as an antioxidant to help remove free radicals in the body. Free radicals are active molecules produced during metabolism that may damage cell structure, leading to aging, disease, and even cancer. Glutathione reacts with free radicals to neutralize them, thereby reducing oxidative stress and cell damage.

**Studies have shown** that glutathione can help reduce oxidative damage in the body and protect cell membranes, proteins, lipids, and DNA from oxidative stress. It plays an important role in maintaining the health of body cells and delaying aging.

### 2. **Detoxification**

Glutathione is present in very high concentrations in the liver because it plays a vital role in the body's detoxification process. It helps remove harmful substances by combining with them to form water-soluble complexes.

- **Heavy metal detoxification**: Glutathione helps remove heavy metals (such as mercury, lead, and cadmium) that accumulate in the body and can cause damage to the nervous system, immune system, and other organs.

- **Drug metabolism**: It reacts with drugs and other toxins during the liver's detoxification process and helps them be excreted through urine or bile.

- **Improved liver function**: Glutathione also protects the liver, reduces the toxic burden on the liver, and helps liver cells regenerate.

### 3. **Support the immune system**

Glutathione is essential for the proper functioning of the immune system. It improves immunity by enhancing the function of white blood cells. Glutathione can promote the activity of immune cells such as T cells, B cells, and macrophages, helping them identify and eliminate viruses, bacteria, and other pathogens.

- **Anti-viral effect**: Glutathione's antioxidant properties can reduce oxidative stress caused by viruses, enhance immune response, and help fight viral infections such as colds and flu.

- **Anti-inflammatory effect**: Glutathione also has anti-inflammatory effects, which can slow the progression of chronic inflammation, improve the balance of the immune system, and reduce the occurrence of autoimmune diseases.

### 4. **Protect the nervous system**

Glutathione is present in relatively high concentrations in the nervous system, and its protective effect on nerve cells is also very important. Since the nervous system is very sensitive to oxidative stress, glutathione helps reduce the risk of neurodegenerative diseases.
