What is Glutathione?
According to the National Institute of Health, glutathione is a “tripeptide” that includes glutamic acid and cysteinylglycine. Put simply, it is something many of our cells use to carry out a variety of jobs. It helps bind to enzymes that then allow for chemical reactions in our body to be carried out. An example is that our body needs enzymes to stimulate the creation of hormones. So, if we do not have enough glutathione, we do not have the building blocks for our cells to work properly, including to detox the body, or create crucial chemicals in the body, such as the stomach acid we need to adjust our food or the melatonin we need to sleep at night properly. If you want to dig deep into the chemistry, you can view the chemical structure and molecular formula on the NIH website.Do We Really Need Glutathione?
Glutathione levels drop as we age, which can majorly affect every cell in the body. Low glutathione levels lead to an impaired immune system, decreased ability to detoxify, and impaired ability to fight free radicals, which combine to exacerbate the symptoms of aging, such as fatigue, slow recovery from activities, prolonged illnesses, and more.

Glutathione – Why it’s A Powerful Antioxidant (Possibly the King of them All!)
You probably know by now that the real OG and king of antioxidant-town in our bodies is glutathione, so it’s absolutely crucial we work on optimizing these levels if we want to have peak energy and strength. Glutathione is the most-produced and powerful antioxidant our body makes and must be produced consistently to maintain our health. Glutathione can help just about everything our body does. Even more importantly, when our glutathione levels are low, we’re at increased risk for aging faster than necessary, illness, and struggling to detox. Essentially, low glutathione levels are going to cause your body to run less efficiently. This will cause chaos with everything your body does. So, knowing the best glutathione supplements to make sure our levels are where they need to be is crucial. Additionally, if you choose our top recommendation, it may be a game-changer for how your body functions, leading to improved long-term health.Why Glutathione is considered the “Master Antioxidant”
Because glutathione influences hundreds of reactions in our body including those that regulate our genes, immune system, and response to inflammation, and more, glutathione has been coined in research studies as the master antioxidant. Put simply, if we don’t have glutathione, or if we have decreased levels of it, the leader in orchestrating many processes crucial for our body to stay healthy are sacrificed and our health will decline.Do Glutathione Supplements Work? (The Benefits of Glutathione)
Glutathione is responsible for the removal of all kinds of “reactive species” and “Persistent Organic Pollutants” (fancy name for chemicals and pollution in our environment). Glutathione is excellent at the removal of reactive species, which are free radicals AKA JUNK in our body that needs to be cleared out such as xenobiotic compounds (AKA foreign chemical substances we ingest from our environment such as pesticides, VOCs etc.), and much more. When it comes to removing this stuff from our body, glutathione is a #BOSS. So, it would be no surprise to know that glutathione supplements have been proven in the research work. However, asking, “Do glutathione Supplements work” is a tricky question though because it neglects to ask what form of glutathione someone is using. The simple answer is yes, they do work, but some are dramatically more effective than others. Liposomal supplements will work much more effectively than non-liposomal forms. In fact, liposomal glutathione was found to be 100x more effective at restoring depleted glutathione levels in cells vs non-liposomal forms.What Studies Show That Glutathione Supplements Work?
When scanning the research to determine the answer as to do glutathione supplements work, many studies are found with conflicting results. While many studies are show its success in helping cancer patients, there are also many studies on healthy individuals showing it was of little benefit. However, most of the studies showing it was of little benefit for various reasons were studies using non-liposomal forms of glutathione. Understanding that liposomal glutathione is ~100x more effective than non-liposomal forms, we cannot translate how liposomal glutathione supplements may benefit us from analyzing research that used non-liposomal forms. Multiple studies show glutathione supplements help reduce neurotoxicity and neuropathy in cancer patients. These studies are not surprising since it is understood that glutathione helps us detox better. What is really interesting for healthy individuals is the research on liposomal glutathione, which shows the benefits of glutathione supplementation including improved immune function and reduced oxidative stress.What is the Most Effective Form of Glutathione?
Liposomal glutathione is the best form of glutathione to take since it is absorbed about 100x more than non-liposomal forms. The problem with glutathione is that it is an amino acid just like many of the proteins we consume. So, our body will break it down like food unless we consume the glutathione in a unique form to help it absorb into the body. This is why it is important to use a liposomal supplement.
Is Liposomal Glutathione Better Than Other Forms of Glutathione?
Liposomal glutathione is glutathione that is delivered inside a liposome. Liposomal glutathione is not better than glutathione; it is simply a better way to get glutathione in your body when supplementing.
Is it Better to Take Liposomal Glutathione?
If supplementing with glutathione, it is better to take liposomal glutathione than non-liposomal forms. If not taken in a liposomal form, a large amount of the glutathione taken in many supplements is broken down during digestion, and very little is absorbed. So, liposomal glutathione is glutathione, a better form of it, that is used to make it easier to absorb through supplementation.How Can I Absorb Glutathione Better?
If you decide to buy some of this magic potion, please know that it’s good to take glutathione intermittently or at most 6 days a week so that you avoid discouraging your body from making its own glutathione. Glutathione is recommended to be taken first thing in the morning, on an empty stomach or at least 10-minutes before a meal, in a liposomal form, and held in the mouth for ~30 seconds before swallowing if in a liquid form. Glutathione levels are lowest in the mornings, which is why many suggest using glutathione supplementation before bed or first thing in the morning.How Many MG of Glutathione Should You Take?
The optimal dose of glutathione should be determined by a qualified healthcare provider and may vary based on your health. For example, if you’re struggling with mold toxicity, you may need to start with a very small dose to avoid the mobilization of too many mycotoxins. If you’re healthy, you may be able to regularly take a large dose.Clinical trials suggest that a higher mg of glutathione dose is not necessarily better than a lower dosage.
Fun Fact: In a study comparing 500 mg vs 1000 mg of glutathione given to healthy adults daily over 4 weeks, the group that was given 500 mg had a greater increase in glutathione in their blood.
How Long Does Glutathione Take to Work?
If taken in liposomal form, Glutathione will start to be absorbed immediately in the mouth. It is best to hold the liquid in your mouth for ~30 seconds or longer to allow the absorption to start before swallowing. Being in a liposomal form will allow the liquid that is swallowed to bypass the harsh environment of the stomach to allow continued absorption of the glutathione in the intestines. If the glutathione is not in liposomal form, much of it will start to be broken down in the stomach, just like any other protein that is consumed.When to Use Caution With Glutathione Supplementation
Important Note: If you experience increased fatigue, nausea, joint or muscle aches, or any other adverse reaction when taking glutathione, seek the attention of a functional medicine-trained dietitian or physician. As Glutathione helps remove toxins, it can cause negative side effects, and you will need further evaluation by a functional-trained specialist to determine if glutathione supplementation is right for you. Depending on the amount and type of toxins released and your specific genetic makeup, taking glutathione could cause harm or trigger other health issues.
Why Milk Thistle Helps Boosts Glutathione as well as Skin and Liver Health
Silymarin is a powerful flavonoid, much like quercetin that is derived from the seeds of milk thistle and can help increase the amount of glutathione. in the liver. In fact, silymarin has been shown to increase glutathione levels in the stomach and intestines in addition to the liver.Bonus: Silymarin has been shown to help protect the liver when taking acetaminophen, the primary ingredient in Tylenol, and many pain relievers.
The Best Milk Thistle Supplement
If you would like to supplement with milk thistle extract, we recommend using Nanoemulsified Milk Thistle by Quicksilver Scientific, which uses a liposomal delivery system for better absorption of the silymarin. It absorbs into the body much, much better than non-liposomal forms, making it more effective.

What to Look For When Buying Glutathione
There are several essential items to consider when looking for the best liposomal glutathione supplement. We know what to look for because we’ve done extensive research on the best supplement brands, have worked hand in hand with a variety of companies, and have learned the hard way on several occasions that not all supplements are created equal.Essential items of the best glutathione supplements:
- 3rd Party Testing: The brand can confirm and show certification that their supplements have 3rd party testing to confirm the purity and dosage of the supplement.
- Production: Supplements are produced in a GMP Certified facility
- Dosage: Do you know how much you want to take? Have you taken it before? Some people can only tolerate small dosages so starting with a liquid that allows you to adjust the dose as needed is recommended
- Ingredients: Are other ingredients included in the supplement and if so, have you assessed how you react to them? For example, is it pure liposomal glutathione, or is it a combination supplement with a super high dose of B12 that has been shown to impair sleep in some individuals?
What Foods are High in Glutathione?
Your body naturally makes glutathione, and if you want to boost it, the most direct way to do this is with supplementation using liposomal glutathione. The reason for this is that the glutathione in many foods is broken down in the gut and poorly absorbed. However, you can use foods to boost your body’s natural ability to produce glutathione. So keep in mind that eating these foods can help provide support, but they likely will not be able to give you a massive boost if that is what you’re looking for.
- Choose citrus fruits, strawberries, broccoli, and bell peppers to bump up your intake of vitamin C-rich foods! When vitamin C stores are up to par, glutathione is spared and less likely to be broken down for other uses in the body.
- Curcumin (turmeric) has been shown to encourage glutathione biosynthesis (converting enzymes into glutathione) within our cells!
- Choosing high-quality animal and plant-based protein each day provides our body with the amino acids that serve as the building blocks to create glutathione.
- Grass-Fed Whey Protein is a precursor for glutathione production in the body. However, please note that this only makes sense if you tolerate dairy and use a high-quality product. Otherwise, we are doing more harm than good.
- Bonus: Spinach, okra, avocados, and asparagus contain naturally-occurring glutathione.

Is Taking Glutathione Orally Effective?
In its raw state, glutathione taken orally is not well absorbed and is easily broken down in the stomach similar to other proteins. However, when taken in liposomal form, glutathione has been shown in several research studies to be an effective form of glutathione to take orally. When taken in liposomal form, absorption of glutathione starts immediately in the mouth, allowing some of the supplement to bypass the digestive process. So, if you’re taking a liquid liposomal glutathione, try to allow some of if to sit in your mouth for 30 seconds or so before swallowing. Additionally, liposomal forms of glutathione help most of the glutathione supplement to avoid being broken down in the stomach and reach the liver, where it can be effectively absorbed. Anecdotally, we can say that oral glutathione, without a doubt, is effective. How can we say this? From working with countless clients in overcoming various forms of toxicity, as well as our own journey with mold toxicity, we can say that taking too much oral glutathione will cause a release of too many toxins leading to an exacerbation of symptoms. Personally, we can say that brain fog, fatigue, vision disturbance, and other symptoms that we only have experienced when exposed to mold have been provoked by dosing with too much oral glutathione. If oral liposomal glutathione were simply being broken down in the stomach, these symptoms would not occur.What to Take if You’re Concerned with The Effectiveness of Oral Glutathione
If you’re concerned about the effectiveness of oral glutathione, our top recommendation is to consider the bullet suppositories by Mitozen which allow you to skip the harsh environment of the stomach and have absorption occur through the rectum. If you’re looking to enhance your sleep, consider the MitoZen SandMan Bullet suppository. If you simply want a pure glutathione product or don’t tolerate high doses of melatonin well, consider their GlutaMax Bullet suppository. Available in 3 different super supraphysiological dosages (a dose that is larger than that found in the body), the MItozen GlutaMax Bullet is available in 250mg, 600mg (most common), and even a massive 1,500mg dose of glutathione. One thing to remember about using the suppository bullet from MItozen is that if you decide using suppositories doesn’t work for you for whatever reason, you may take the bullets orally. You may cut them up to be taken in smaller dosages if needed as well. Read More >>> Surprising Glutathione Supplement Side Effects. As always, we’ve tried this product and can state that, without a doubt, it is a high-quality, highly potent liposomal glutathione supplement!Reduced Glutathione vs Glutathione
Glutathione is available in two different forms in the body- reduced and oxidized. The reduced form is often abbreviated as GSH, while the oxidized form is abbreviated GSSG. The ratio of reduced glutathione to oxidized glutathione is often a measure of health, as having high amounts of oxidized glutathione is present in times of extreme stress or injury, shock, and in neurodegenerative diseases.Why You Need to Be Careful When Supplementing with Glutathione
One extremely crucial note to keep in mind with glutathione supplementation is that while it can be extremely helpful to a variety of people, it is not for everyone and can in fact be harmful to some. Keeping in mind that glutathione helps our body detox, some people need to be extremely careful in how they detox and how quickly they do it. Whether someone is trying to detox from mold illness, heavy metals, or any other number of issues, detoxing too quickly can cause extreme fatigue, harm the immune system, and lead to additional undesirable health issues.

Final Thoughts on the Best Glutathione Supplements
Hopefully, by now, it is clear there are a lot of great supplement options available, and the best glutathione supplements for you may vary depending on the dosage and delivery system you desire. Determining the best liposomal glutathione is not a one-size-fits-all all answer, and one could easily argue which ones deserve to be at the top of our list. When considering the question, “what is the best form of glutathione to take?”, liposomal forms have hands-down been proven in the research to be better absorbed and more effective than non-liposomal forms. It should be known that when wondering how long does glutathione take to work if taking a liposomal version, whether by powder, liquid, or suppository, it can start to be absorbed almost immediately and begin to work within minutes. However, for glutathione to really “work,” it really requires 2 weeks or more to see glutathione levels in the body increase. In the vast array of delivery systems highlighted in this article, we hope we’ve also answered the question of how to take liposomal glutathione. There are a variety of answers to this question, and none of them are wrong. Once again, the true answer to this question will depend on the individual, as the research has clearly validated that different delivery systems can all be effective. The one key point to consider is that if taking a liposomal liquid, hold it in the mouth for 30 seconds or more to allow it to begin absorption right away. If you’re curious if glutathione is a good fit for you or if you’ve taken it and noted increased fatigue, it would be best to discontinue supplementation and consult a highly qualified dietitian who can perform a detailed evaluation and determine the best path for you to achieve optimal health whether that is with or without glutathione.
