9 Glutathione FAQs
Below are 9 common questions we get asked, as well as questions people frequently ask online.
Let’s start with the most basic, just in case you’re completely unfamiliar with glutathione!
1. What is glutathione?
Glutathione is a molecule that is produced naturally in the body. It is a tripeptide, made up of three amino acids (cysteine, glutamic acid and glycine) and is found in high concentrations in the liver.
Glutathione plays a crucial role in many processes in the body, including antioxidant defense, detoxification, and regulation of cellular metabolism. It helps neutralize free radicals and protect cells and tissues from oxidative stress, and is often called the “master antioxidant”.
2. What are the benefits of glutathione?
Glutathione is touted for its many health benefits, including:
- Antioxidant protection: Glutathione acts as an antioxidant in the body, helping to neutralize harmful free radicals and prevent cell damage.
- Immune system support: Glutathione is involved in the regulation of the immune system and may help boost immunity.
- liver health: The liver is the primary site of glutathione production and metabolism, and glutathione is important for liver function and detoxification.
- skin health: Glutathione is sometimes used as a skin lightener and, thanks to its antioxidant properties, it can help improve skin health and reduce the appearance of wrinkles.
- Neurological health: Glutathione has been shown to play a role in regulating neurotransmitters and protecting neurons.
- Cancer prevention: Some research suggests that glutathione may play a role in preventing certain types of cancer by blocking oxidative damage and reducing inflammation.
3. How does glutathione work in the body?
Glutathione works in the body in several ways, including:
-

Molecular model of an enzyme. Antioxidant Defense: Glutathione acts as a powerful antioxidant, neutralizing free radicals and preventing cell damage caused by oxidative stress. Amazingly, it can do this anywhere in the body and has even been shown to boost and replenish other antioxidants for extra support.
- Detox: Glutathione helps detoxify harmful substances, including heavy metals, chemicals, and drugs, by binding to them and making them more soluble for elimination from the body.
- Regulation of the immune system: Glutathione is involved in the regulation of the immune system and has been shown to play a role in the activation of immune cells, such as T cells and natural killer cells.
- Enzymatic regulation: Glutathione plays a role in the regulation of enzymes involved in cellular metabolism and redox reactions.
- Protein synthesis: Glutathione is involved in protein synthesis and the maintenance of protein structure.
In summary, glutathione is involved in many important processes in the body and is essential for overall health and well-being.
4. What are the side effects of glutathione?
Glutathione is generally considered safe when taken as directed. However, some people may experience side effects when taking glutathione supplements, although most of these are special cases or occur when people take extremely high doses.
These include:
- Nausea: Some people may experience stomach upset or nausea after taking large amounts of glutathione.
- Skin irritation: Glutathione is sometimes used as a skin lightener and may cause skin irritation or itching in some people when applied topically.
- Allergic reactions: Rarely, some people may have an allergic reaction to glutathione, including symptoms such as itching, hives, or swelling.
- Drugs interactions: Glutathione may interact with certain medications, such as antipsychotics, chemotherapy drugs, and HIV medications, and may affect their effectiveness.
It is important to speak with a healthcare provider before taking glutathione supplements if you have a pre-existing medical condition or are taking other medications.
5. Is glutathione safe to take?
Glutathione is considered safe when taken as directed. However, as with any supplement, the safety and effectiveness of glutathione can vary depending on a number of factors, including the health status of the individual, the form of supplementation, and the dose taken.
Additionally, the quality and purity of glutathione supplements can vary widely, and it’s important to buy from a reputable source to ensure you’re getting a high-quality product.

6. Does glutathione boost the immune system?
Glutathione is involved in regulating the immune system and studies suggest it may help boost immunity. It does this in three main ways:
- Protection of our immune cells thanks to its antioxidant activity.
- Optimization and improvement of the function of our lymphocytes (these are white blood cells which are also one of the main types of immune cells in the body used to fight infections).
- Decreasing inflammation and preventing damage caused by free radicals. Glutathione-enhanced T cells (another type of immune cell) are able to produce more anti-infective substances, thereby controlling bacterial and viral infections.
7. Can glutathione be used as an anti-aging treatment?
Glutathione has been shown to have anti-aging effects inside and out. These include:
- Decreased production of wrinkles and increased skin elasticity
- Decreased inflammation and/or puffiness of the skin, which tends to increase with age. As a result, glutathione helps make the skin more supple, firmer and able to retain more moisture.
- Protects mitochondria from oxidative damage and free radicals. Mitochondria are the cells that produce ATP used for energy, so glutathione also helps with energy production and fat burning.
- Since many diseases are linked to low levels of glutathione, this can reduce the risk of developing health problems.
- It may be able to slow or prevent hair from graying.
- Free radicals and the oxidative stress they cause can cause you to age faster, so having optimal levels of glutathione to combat this can slow the signs of aging throughout the body.
8. How much glutathione should I take?
The recommended dose of glutathione may vary depending on the form of supplementation and the health status of the individual.
There is no established recommended daily dose for glutathione supplements, and the optimal dose may depend on a number of factors, including age, weight, and general health.
In general, oral glutathione supplements are available in doses ranging from 250 milligrams to 1,000 milligrams per serving, and intravenous (IV) glutathione is administered at a dose of 500 milligrams to 2,000 milligrams per session.
Some supplement companies will increase the dosage because they know their formula is not very absorbable, and they hope that by doing so at least some of it will make it into the bloodstream. However, this is often not the case.
9. Where can I buy high quality glutathione supplements?
The sad truth is that most glutathione supplements simply don’t work. Unfortunately, they do almost nothing. Tests reveal that very little glutathione from supplements is actually absorbed.
Since glutathione is made up of three amino acids, our bodies metabolize it too quickly for proper absorption.
Researchers have tried to find ways around this, such as providing the body with more tools to synthesize glutathione on its own, intravenous therapies, transdermal creams and others. But these are either impractical or simply old don’t work.
This is where a new method has arrived.
The one that raised glutathione levels by 40% after just one week of daily use! It has also been found to decrease markers of oxidative stress and boost immune cells, with some crucial immune cells elevated by 400%! [1]
The method uses liposomal glutathione. If you’re taking glutathione, you have to take it in liposomal form or you’re wasting your time.
Purality Health Micelle Liposomal Glutathione provides you with a dose of quality glutathione every time.
It’s a difference you can FEEL.
And if not, you can get a complete refund within 6 months of delivery. No questions asked.
