What’s the latest cleanse? Sipping on fresh lemon juice, in a near IR sauna, covering your body with avocados, and giving yourself a coffee enema simultaneously. Yeah, have fun with that! The problem with all of these cleanses and detox fads is that they go against basic biology. When the body detoxifies a toxin, it uses a compound called glutathione.
What is Glutathione?
Glutathione is one of the most important compounds in nature. It is made up of a peptide (a very short protein) comprised of the amino acids glutamate, cysteine, and glycine. In biology, we refer to this unique pattern as a thiol, which is a chemical group that carries an extra electron so that it can be donated.
What are Antioxidants and Free Radicals?
There are many antioxidant compounds out there, but none are as important as glutathione. An antioxidant is a compound that carries a negative charge and is capable of donating electrons. A free radical is a compound that carries a positive charge. When a compound becomes positively charged, we call this oxidation. It is a little confusing because oxidation sounds like oxygen, but they have no relationship with each other. Opposites attract, and glutathione is perfect for scavenging free radicals, donating a free electron, and neutralizing the radical. The free radical is positively charged because it lacks an electron, and the glutathione molecules give their electrons to the free radicals making the charge neutral.
What about toxins that are not positively charged?
Free radicals are not the only toxins in the body. There are lipid peroxides, heavy metals, and metabolic waste. Glutathione uses a different mechanism for detoxifying these compounds called conjugation. This is when glutathione binds to the toxin at a specific site so that it is neutralized and can be excreted. Both the antioxidant method and the conjugation methods use up glutathione in the body and the liver must produce more.
What happens to the Glutathione that is used up?
When glutathione is used as an antioxidant, it gives up an electron, or oxidizes. It then becomes a positively charged ion. Two glutathione ions find each other and bind together forming a compound called glutathione disulfide (GSSG). If it is used in a conjugation (binding) reaction, the molecule is usually excreted from the body and lost, whereas GSSG can be recycled back into reduced (gaining an electron) glutathione. This can be done with the aid of other antioxidants like vitamin C.
How does the body make Glutathione?
When the body loses enough glutathione, it must produce more to prevent cellular damage. The liver produces the enzymes gamma-glutamylcysteine synthetase (connecting the glutamate and cysteine amino acids) and glutathione synthetase (finalizing the chain with glycine). The body uses amino acids from the food that we eat. Glycine and glutamate are abundant in the body and in our foods, but cysteine is rarer and is one of the determining factors in how much glutathione the body can make.
What can you do to make the body produce more Glutathione?
N-acetylcysteine (NAC) is the supplement form of the amino acid cysteine which is one of the rate-limiting factors in the synthesis of glutathione in the liver. Taking N-acetylcysteine supplements the body with the cysteine required to make glutathione. The supplement is kind of a double edged sword because excess cysteine is toxic and can have the opposite effect of what you are looking for. We recommend the Jarrow brand if you want to try it:
- It does a good job of raising glutathione levels in the body on a limited scale.
- It chelates bad biofilms in the gut.
- It has been shown to have toxicity when taken in doses over 1200mg.
- It chelates good biofilms in the gut.
- If you are under heavy toxic pressure, it may not be enough.
Oral GSH, or Glutathione
Some companies sell glutathione powders, capsules or tablets. The problem with the oral route is that glutathione is broken down into glutamate, cysteine, and glycine by enzymes in the digestive system. It’s not that it won’t raise glutathione levels (because it will to some degree). The body will use the cysteine (which is the conserved amino acid needed to make glutathione). It is an inefficient way to raise glutathione, and so we do not recommend the oral route.
- It is sometimes cheaper than some of the other options.
- It does not raise glutathione in the body effectively.
Intravenous (IV) glutathione is the most effective way to increase glutathione levels in the body. If I were in the hospital, and my liver was failing, I would do everything I could to get myself hooked up to an IV bag with a glutathione solution in it. It bypasses the digestive system, so it is 100% absorbed.
- It is the most effective way to raise glutathione in the body.
- It is invasive.
- It requires special equipment and should be done by a healthcare professional.
- It is the most expensive method.
- It is not very practical.
Liposomal technology is an innovation from the pharmaceutical world that allows compounds to enter into human cells taken orally, yet bypassing the digestive system. Engineers have found a way to wrap the compound in a liposome, or a spherical bilayer sheet.
- It is the most practical way to raise glutathione levels in the body.
- It can raise glutathione levels higher than natural levels for extra support.
- The liposomes are also good for your cell membranes.
- Liposomal glutathione is difficult to make.
- It is unregulated and there are a lot of counterfeits on the market.
- It is hard for the consumer to find a quality product.
Producing liposomal glutathione is expensive, and it is difficult to achieve the specific phase state to allow the fats to surround the precious glutathione molecule. Let it get too hot or too cold, and you have some expensive sludge. Use the wrong pH, and the liposomes break apart. Fail to stabilize the electric charge, the glutathione leaks out. Some manufacturers of liposomal glutathione simply don’t have the science background to know what they are doing. Others know they are ripping off the public and think that they can get away with it.
[UPDATE: We currently recommend Formline Performance Liposomal Glutathione]
We used to recommend a brand of glutathione that we thought would help people, but the company that sold it changed their formula. We reached out to them for comment and followed up with them several times. They simply keep responding, “I have forwarded your email to our product team and will let you know once they send me a response. Thanks!” After a few months of this, we decided to do our own independent testing of this product, and it turned out to be another inferior glutathione supplement. We had to look for a new product to recommend and ran across many other ineffective formulations like it. Some of the common problems that we see in just about every glutathione supplement are:
There is a loophole in the marketplace. You are allowed to advertise that an ingredient in your product is phosphatidylcholine as long as it contains 30% phosphatidylcholine. Most manufacturers simply substitute sunflower lecithin instead. The ingredients look right on paper, but lecithin will not form liposomes. Almost every product we tested used lecithin rather than phosphatidylcholine, and it is the wrong phospholipid for the job. Only pure phosphatidylcholine will work.
Many companies store their product in warehouses without climate control. They make large batches and some sit on the shelf for a year or more. Liposomes do not have a very long shelf life and the heat will destroy them.
Uncontrolled Phase State
Manufacturing liposomes is a mathematical process:
Ntot = [4π(d/2)2 + 4π[(d/2) – h]2 / a
Companies mess this formula up because they:
- Use supporting lipids that are too short.
- Are not sufficiently hydrating the liposomes.
- Fail to use sufficient amount of phospholipids.
We have even seen products that look as if they were simply blended instead of using sonic or high-pressure techniques.
If you see a “liposomal” product that is not liquid, it is not liposomal. I have asked some companies selling powdered, or encapsulated “liposomal” products about their rationale and they tell me that their product is “pre-liposomal” and say that once you drink the solution, it will form the liposomes in your stomach. If you were able to read and understand even half of the information above, you know that that is impossible. Don’t waste your money on this. It is the least effective way to increase glutathione in any of the areas that we have mentioned.
When to Take Glutathione
People who are sick or are on medications benefit from taking glutathione every day. In other people, taking glutathione, every day will actually prevent your body from making its own glutathione. I recommend that people take a large dose once per week to optimize their health, or just take it as needed. If you are stressed out, had a night of heavy drinking, were on an airplane, or spent time in a toxic environment, your body may not produce enough glutathione to keep up with the need, and you might want to supplement.
Bulletproof was the company that changed it and we never could find out why i took it by spoon everyday then never got it again because they changed it
Thanks for this post. I would like to use some portion of this post on my blog if you permit. Thanks
Is it accurate that glutathione reducing melanin pigment ?
Hi – my husband has been taking Quicksilver liposomal glutathione and now I’m questioning this as he definitely sways towards Th1 immunity as he has psoriasis (which started nine years ago after a flu shot and amalgam removal (done improperly). The more we read and research (Cutler, Klingjardt, Chris Shade and so man others the more confused we get (about detox). He has been on a paleo diet (strict – we focus on pastured meats, good fats and wide variety of organic vegetables) for 8 years – we’ve done every variation (GAPS, Low FODMAP, AIP, Keto, etc) and he’s been to so many holistic and functional practitioners (his case is severe). Latest doctor believes it’s histamine and yeast so did antifungals, DAO/histamine blockers/quercetin, etc with no luck. He has consistently taken probiotics (GutPro and currently Seeking Health Probiotica Histamix). Husband gets plenty of sun, sleeps well and has low stress (except his body covering psoriasis). He’s 44 and is in phenomenal shape (personal trainer) – blood markers are impeccable and no other health issues. Normal/regular bowel movements. We are at such a loss……Any insight?
Skin problems are often liver related. Possibly some mercury toxicity as you mentioned improper amalgam removal.
Maybe look into mineral and heavy metal hair analysis by ARL
have you tried colostrum? sovereign labs has colostrum backed by lots of research. you can read lots of success stories on their website about people with skin issues
When should it be taken?
Actually, Oral glutathione does increase glutathione stores in the body. (https://www.ncbi.nlm.nih.gov/pubmed/24791752) Even though some glutathione gets oxidized during digestion, it still can get absorbed. (https://www.ncbi.nlm.nih.gov/pubmed/25198144) Unless you think these studies are flawed? Thanks for all your awesome work.
Thanks for the information about supplemental glutathione. I have Hashimoto’s (including elevated antibodies to thyroid gland), but how do I know if I’m Th1 dominant?
My nutritional DNA variants include ACAT so metabolically, the protein, fats, and carbs I consume don’t produce energy. I am also anemic from malabsorption problems after cholocystecomy-gall-bladder removal and I don’t absorb iron well
although I’ve recovered from using organic blood builders. Undiagnosed Type II diabetes – A1C hovers at 6 because I am diligent with diet.
I’m age 58, female,think,active from lots of glutamate variant also, but still
have gut issues that I think could be helped with your product. I do take glutathione capsules from Tree of Life Health Ministries is Ephrata, PA because I have glutathione variant also.Found a glutathione product from Amazon for half the price.
What do you think of using glutathione recycling supplements?
“Glutathione is one of the most important compounds in nature. It is made up of a peptide (a very short protein) comprised of the amino acids glutamate, cysteine, and glycine. In biology, we refer to this unique pattern as a thiol, which is a chemical group that carries an extra electron so that it can be donated.”
The part where you say “this unique pattern” implies that it’s the three amino acids that make it a thiol. That is incorrect. “Thiol” refers to any molevule with a sulfhydryl group (-SH) attached; -SH is present on glutathione due only to the presence of cysteine, the amino acid containing a sulfhydryl group. There’s nothing unique about the pattern Glu-Cys-Gly that causes this, it’s just the Cys itself.
Another powerful antioxidant to consider is CoQ10. What are your thoughts on this?
I have two caveats on glutathione. First, if you read the work of Andrew Cutler, you’ll find anecdotal evidence of those with mercury amalgams or otherwise mercury burdened having issues with glutathione, and I cannot recommend it for them (definitely not IV glutathione). Second, individuals who are suffering from Th1 dominance might do better not supplementing glutathione. These things aside, I have known glutathione to help many people with their health issues and I recommend it in the Fix Your Gut eBook and to my clients. http://www.pnas.org/content/95/6/3071.full.pdf, http://cutlersuccessstories.weebly.com/what-not-to-do.html, http://www.livingnetwork.co.za/chelationnetwork/chelation-the-andy-cutler-protocol/
What issues does it cause for those of us with mercury fillings — which I venture to say, is many of us!
It would displace mercury throughout the body. It could deposit it to other parts of the body without fully chelating it.
