Glutathione is a peptide made up of three amino acids, known for its anti-ageing properties and its role in a long and healthy life. It is a very powerful antioxidant that is found and continuously produced in the human body, protecting it by neutralising harmful free radicals and reactive toxic molecules.
Glutathione is one of the most important of the many molecules we rely on to stay healthy and protect our bodies. It plays a key role in limiting the damage caused by substances such as tobacco and alcohol, which harm the body over long periods. Free radicals also play an important part in the development of age-related health problems and chronic conditions such as vascular disease and dementia. Because glutathione helps neutralise free radicals, it is considered an important support in reducing this oxidative burden.
As well as helping protect the body against many harmful substances, glutathione’s detox effect helps protect against the damaging effects of free oxygen radicals that accumulate in tissues and cells, and it supports the immune system.
Glutathione, regarded as the most important antioxidant, is not always present in sufficient amounts in the body. When levels are lower than they should be, supplementation may be needed. The most effective way to raise active glutathione levels is intravenous (IV) administration. IV glutathione enters the bloodstream immediately and without loss, helping protect the body against free radicals and supporting the cells.
Benefits of glutathione therapy
Glutathione molecules play a direct role in supporting the immune system. They help protect the body from harmful radicals and contribute significantly to its defence mechanisms. Glutathione therapy may also support energy levels and muscle performance and help ease joint and muscle aches. With its regenerative effect it supports skin renewal and radiance and may contribute to a brighter complexion. Its possible benefits for focus and for neurodegenerative conditions such as Alzheimer’s disease are an area of ongoing research.
Side effects of glutathione therapy
Glutathione therapy is used widely around the world and is generally well tolerated. Because glutathione is a substance that is normally present in the body, side effects are uncommon; mild bruising at the IV site and, rarely, allergic reactions may occur.
How is glutathione therapy given?
Glutathione therapy is the easiest and most effective way to raise glutathione levels in the body, and this is done by IV infusion into a vein. Giving glutathione intravenously is a fast and effective method used widely around the world. Each infusion counts as one session, and the number and frequency of sessions can vary from patient to patient. After the treatment, you can return to daily life straight away.
