Although long known to the discipline of biochemistry, what is glutathione is only now becoming popular as a dietary supplement. Nicknamed the “master antioxidant,” glutathione has key functions in detoxification and protects the cells from damage due to the effects of oxidative stress. The tripeptide’s other functions have yet to be established definitively, but its physiological importance is unquestioned. Glutathione is a molecule found in virtually every cell of the body. The ability of glutathione to interact with proteins and molecules at several cellular locations can facilitate many physiological processes: DNA repair, protein repair, neutralization of heavy metals, deactivation of drugs and metabolites, and facilitation of immune response. Glutathione can be biochemically distinguished by its chemical structure, which contains its cysteine amino acid bonded to the neurotransmitter glutamate. Biochemically, glutathione benefits contains a chemical structure distinguished by its unique cysteine amino acid bound to the neurotransmitter glutamate. Glutathione is distributed widely among many foodstuffs, although particularly high concentrations are found in foods like globe artichokes and bovine diet. Poultry, eggs, and dairy products also contain more modest amounts of glutathione. Yeast is a base for many fermentative products, such as alcoholic beverages and vinegar; it contains relatively high concentrations of glutathione. Better health conditions are associated with higher blood levels of glutathione, whereas poor health conditions correspond to its depletions, including but not limited to increased levels of lupus, atherosclerosis, Parkinson’s disease, among many more. Some clinical researchers take an interest in studying diseases with a view of glutathione for that reason.
Glutathione has also been called the “master antioxidant.” It is an extremely powerful molecule associated with all the major systems in the cell, whose role is to protect the cells from oxidative stress and maintain health in general. Glutathione is composed of amino acids such as cysteine, glutamine, and glycine, which neutralize the harmful free radicals and, unless regulated, will cause cellular damage and have implicated involvement with the aging process and host chronic diseases. This antioxidant action has reduced inflammation, strengthened the immune system, and assured repair processes at the cellular level. Glutathione benefits also participated in detoxifying the liver and in helping facilitate the excretion of toxins from the body, further preventing pathologies caused by oxidative stress: cardiovascular diseases, diabetes, and certain cancerous conditions.
Besides its role in antioxidant activity, glutathione is important in energy production and metabolic function. This makes the mitochondria better, which are the body cells that produce energy and extremely important in cellular regeneration. The person who suffers from a chronic fatigue or generally, low levels of energy may find this particularly important. Glutathione is also involved in DNA synthesis and the generation of proteins, ensuring skin, hair, and nail health. Glutathione makes the person look younger, clears skin discoloration, and contributes to even skin tone-all those very desirable features for people seeking anti-aging glutathione benefits, hence the reason it is popular for both wellness and skincare routines.
Following findings in the late 1990s that glutathione levels could be different in those who crowded in the initial recovery period after surgery, interest grew in the potential therapeutic application of glutathione supplementation for individuals with poor health. The uses of glutathione benefits in health and medicine can be broadly broken down into: – general detoxification support – ‘whitening’ or other forms of skin health – a source of extracellular thiol groups for antioxidant therapy – down-regulation of the immune response in the treatment of autoimmune diseases – reducing neurological consequences of a diverse range of medical conditions. Glutathione is usually supplied as a powder for oral supplementation or as an injectable for intravenous use. Preliminary studies report potential for decreasing signs and symptoms related to medical treatments and cosmetic appearance depending on the specific lotion used. Although far from unequivocal, many case reports and small studies do show clinical glutathione benefits, especially from the intravenous form. Often these reports and studies discuss improved tolerance of traditional cancer treatments such as chemotherapy. Intravenous aldministration of most compounds increases absorbed dose compared to oral delivery, potentially affecting the overall benefit of the intervention. However, due to the significant inconvenience associated with actual intravenous administration, it has not been widely compared to oral administration, and so evidence suggesting superiority of intravenous delivery must be treated with caution. Collectively, the preponderance of evidence in favor of glutathione as a therapeutic in humans includes a very large number of small clinical studies, case reports, as well as two small to moderate randomized controlled trials. In at least some studies, glutathione has been demonstrated to affect clearance of small molecules from the body via changes to metabolism and inflammation. In other cases, mainly when delivered via intravenous injection, glutathione has been reported to reduce complications and symptoms of idiopathic pulmonary fibrosis, advanced non-small cell lung cancer, diabetes, irritable bowel syndrome, and possibly other conditions.
Many experts criticize glutathione supplementation for its low bioavailability and have questioned the usefulness of supplementing with glutathione. However, many researchers have begun to investigate is glutathione harmful topic, and there are some producers who have begun to enhance glutathione availability and effectiveness. While the opinion on this topic is controversial, the issue is slowly catching the attention of the scientific community. The fact that it is well-tolerated in the body does not imply that glutathione supplementation cannot be abused. Despite the fact that high doses of glutathione have not been found to be acutely toxic, prolonged use may have negative side effects. Is glutathione harmful? In some patients, the use of glutathione can be harmful. Every patient can react differently to a substance because every patient is different. Consequently, the treatment and supplementation of nutrients should be personalized. Using the natural form of glutathione does expose the patient to an overdose risk, even if no known side effects have been reported so far, as it does not involve harmful chemicals. Antioxidant imbalances are a possible safety issue, and glutathione therapy can alter a person’s oxidant/antioxidant balance. Reduced glutathione can then start acting as a pro-oxidant. Most of the medication that has a negative reaction against glutathione is, unsurprisingly, a chemotherapeutic. If you are taking any of these drugs, you may require a replacement glutathione level. There are potential adverse effects when combining glutathione with certain medications. What should be the dosages? We don’t know the appropriate dose of glutathione or how long it should be given. For how long? For how long? Because many people are given antiviral medications and supplements, it is difficult to tell if the injury resulted from the medication, the supplements, or a combination of the two.
Glutathione, in general, is considered very popular through supplement or IV treatment and has shown its comparative before-and-after effects in skin health and detoxification. Usually, clients would describe how, prior to their glutathione supplementation, they had symptoms such as low energy, sallow, uneven skin tone, and even increased susceptibility to infection from low immunity. Many also report inflammation or issues related to oxidative stress, such as fatigue and impairment of detoxification processes, prior to glutathione supplementation. Glutathione before and after works by neutralizing free radicals, supporting liver function, and boosting the immune system-all precursors to noticeable improvements in wellness.
After being on a routine of glutathione-through diet, oral supplementation, or even intravenous treatment-the skin is much brighter and more even, with better skin elasticity due to its potent antioxidant properties. Glutathione before and after plays a detoxifying role in the body, which might improve energy levels by getting rid of some toxins that may increase skin blemishes and lead to general fatigue. Many people also report improvements in symptoms related to chronic fatigue, inflammation, and immune system function. Before-and-after reported changes with glutathione supplementation underscore its role as a “master antioxidant” that supports health, energy, and skin appearance from many perspectives.
In the context of glutathione, future research could seek to explore its functions at a subcellular level. This includes identifying new interaction partners of glutathione and understanding its mechanistic roles during physiological and pathological processes. In addition, future studies could explore the use of glutathione benefits in mental health, since this field has been little studied so far. Aging-related diseases and glutathione, as well as its interactions with other antioxidants and compounds, could be explored more specifically to determine what role glutathione plays in these processes. These are just a few possible indications to guide future research. The gaps in our understanding is glutathione harmful in health and disease suggest that further clinical trials are needed to guide the scientific community and patients about potential applications. The optimal dosage and administration mode, possible contraindications of long-term supplementation with glutathione or its precursors, and its health benefits, especially with regard to preventive effects in the population, must be carefully investigated for indications in research and new findings. In conclusion, this review aimed to synthesize and discuss the contradictory information currently available in the literature on glutathione. The most important message to be conveyed here is that, despite the way these findings may be interpreted, it is always important to view scientific results from a holistic point of view. This holistic view will enable us to draw population-specific policies. Also, it will enable practitioners to advise their clients, following current guidelines. All precautions must be taken to advance in the area of glutathione research in order to establish as much as possible the fine line between the glutathione benefits and risks of its administration.
