Glutathione (GSH) is an important tripeptide with multiple critical functions in cells, including antioxidant, detoxification and intracellular environment maintenance. In recent years, liposomal glutathione has attracted much attention as a delivery system for GSH in drug discovery and biomedical applications. Below we will delve into the similarities and differences between these two forms of glutathione and the advantages of liposomal glutathione over free GSH.
What foods contain glutathione?
There are more foods that contain glutathione, which can be broadly categorized as follows:
Fruits: kiwis, cherries, lemons, etc.
Vegetables: tomatoes, onions, garlic, parsley, etc.
3. Nuts: walnuts, peanuts, etc.

4. Meat: pork liver, lamb liver, chicken liver, fish, etc.
In addition, cabbage, broccoli, cauliflower, and choy sum also contain glutathione, as do whole grains, animal offal, shellfish, and yeast.
Similarities:
♦Core Component: the core component of both free glutathione and liposomal glutathione is the glutathione molecule. This means that both have essential similarities in biological activity, structure and function.
♦Antioxidant properties: Glutathione is one of the most important intracellular antioxidants, capable of scavenging free radicals and reducing oxidative stress, thus protecting cells from damage. This property is retained in both free and liposomal forms.
♦Detoxification: Glutathione plays an important detoxification role in the body, helping cells to eliminate a variety of harmful substances. This is common to both forms of glutathione.
Differences:
♦Stability: free glutathione may become unstable when exposed to air, light, or pH discomfort, resulting in a decrease in its biological activity. In contrast, liposomal glutathione utilizes the protective effect of liposomes, making it more stable under unfavorable conditions.
♦Cell permeability: Liposomal glutathione, due to its special liposome structure, is more likely to penetrate cell membranes, thereby increasing the concentration of GSH within the cell. This is important for improving drug efficacy and reducing side effects.
♦DRUG DELIVERY: Liposomal glutathione is not only a biologically active molecule, but also serves as a drug delivery system. Through liposome encapsulation, controlled release of drugs can be achieved, improving drug targeting and bioavailability.
Advantages of liposomal glutathione over free glutathione:
1.Enhanced stability: as mentioned earlier, the liposome structure provides better stability for glutathione, making it more reliable during storage and use.
2.Improved cell permeability: The liposomal form makes it easier for glutathione to enter cells, thus enhancing its effects in the organism.
3.Drug delivery capability: Liposomal glutathione is not only biologically active, but can also be used as a drug carrier for targeted delivery and controlled release of drugs. This property provides new possibilities for drug development.
4.Reduced side effects: Through the targeting effect of liposomes, the damage of drugs to normal cells can be reduced, thus reducing side effects.
（IMP）To summarize, glutathione and liposomal glutathione share structural and functional similarities, but the liposomal form offers better stability, cell permeability, and drug delivery capabilities. These advantages give liposomal glutathione greater potential for drug discovery, biomedical applications and disease treatment. With further research, we have reason to believe that liposomal glutathione will play an increasingly important role in the biomedical field in the future.
