Like oxygen, water, and nourishment, glutathione is an essential tripeptide required for life. Made primarily in your liver and found in virtually every human cell, it is the body’s master antioxidant and arguably the most potent barrier against disease, toxin, and mutation.  It is likewise a key factor to first-line-of-defense immune response, rebound, and repair. Although critical glutathione levels will lower as we age, depletion can be accelerated by stress, illness, infection, poor diet, alcohol, cigarettes, trauma, and environmental toxins. This depletion can manifest itself in ways that might include impaired nutrient absorption and assimilation, gut, lung, eye, blood, skin, and brain issues, keloid scarring, mitochondrial stress for lower energy output, DNA mutation, mass oxidation, and free radical overload (1). Theranaturals Reduced L-Glutathione Plus™ is engineered for enhanced absorption and potency with ultra purity grade OPITAC glutathione and sodium bicarbonate. We do not use fillers, excipients, or flow agents.  Supplementation has proven clinically favorable and may be beneficial to you. Naturally support optimal cellular function and immune response with Reduced L-Glutathione Plus™. Breathe easy, enjoy, live life. 

How to prepare:

Break capsule open and empty content into container or nebulizer cup. Add 1-2 ml (~1/2 tsp) distilled water or pure saline solution. Let stand or agitate briefly until solution is perfectly clear. It’s now ready to use.  

Note: Do not use Ultra-Jet, heat based vaporizers, or any enhanced high speed type nebulizers – these can destroy the glutathione. We have tested and can recommend the following nebulizers: 

Omron NE-C801 Lightweight, Omron NE-C30 Compact Portable, or Omron NE-U22V Ultra Compact Portable

NOTE: the above tested nebulizers are not required to use our glutathione. Any standard nebulizer should work fine.

Warning: it is not recommended that you take glutathione if you are undergoing chemo or radiation therapy for cancer or any other condition. As a powerful antioxidant, glutathione can cancel out the treatments and render them ineffective. Consult with your doctor first before supplementation. In addition, Whey Protein Isolate and NAC should also be avoided if undergoing treatments as they both stimulate glutathione production in the body and can likewise counteract the therapy. Thirdly, If you have been exposed to the black mold Stachybotrys chartarum (a toxic mold that infects the lungs) and have a lung infection suspected or diagnosed to be related, it is not recommended that you nebulize (oral is okay) with glutathione until the mold is treated by a medical professional via antifungals. The black mold appears to absorb the free glutathione very readily through it's slime head and protects itself from normal human immune response. Use extreme caution if you suspect a Stachybotrys chartarum infection and toxicity or have been diagnosed with a related stahybotrys chartaum issue by a medical professional.

Exceptional Product - Lessons Learned


My name is Marilyn, I am now 60 years old, and I was diagnosed with Primary Progressive Multiple Sclerosis in 1992. My MRI showed hundreds of pinpoint lesions. By 2004, I could not walk at all. I do not have remissions and I have continuously progressed. I have never taken the standard MS medications because I did not see much evidence that they were worth the side effects or the cost. After seeing dozens of doctors of all sorts, the only laboratory tests that showed any obvious problems were those involving mercury toxicity and the metabolic functions that the toxin disrupted.

My journey has been lengthy. I have done every conceivable naturopathic therapy I could find that I thought might improve my situation, including intravenous chelation agents. I am almost embarrassed to list how many different protocols I followed without result. While some things were beneficial, indeed critical, like liothyronine (thyroid medication), I was not successful at reversing any of the creeping paralysis that was slowly removing any ability to move any limb. I found some pain relief using cannabis oil (doctor prescribed), and it also helped sleep, but I did not see any improvement in mobility, in fact, within one year I lost all hand function in both hands. I seemed to be in an accelerated decline.

Fortunately, in Seattle I met a physician whose brilliance was immediately apparent and I began to work with her. Employing her years of knowledge treating environmental illness/toxicity, she recommend a 3 component cocktail that would be best nebulized. As I have some nutritional background, and some knowledge of alternative therapies, I recognized what this original cocktail of synergistic ingredients should be capable of. Also, and I truly believe this due to my experience that I will delineate shortly, I believe that this cocktail could very well be beneficial in treating any of the neurological conditions that have exploded in the last few years. I am talking Alzheimer's, Parkinson's, TIA damage… This therapy can be done at home at your convenience, painlessly without side effects and affordably, and in my personal case, it is only made me feel better. My paralyzed hands are responding to this treatment, they are no longer frozen into claws, but are able to stay extended and I can now move my fingers to some degree. This is to me miraculous is remember I am considered incurable, hopeless Primary Progressive. All my joints are looser.

So what is this cocktail that I am talking about?

It is a mixture of liquid zeolite ACZ (, ACS liquid silver ( and Theranaturals buffered glutathione. I am going to record my method of administration. Understand, I am not giving medical advice, I am simply relating what my experience has been. Your mileage may vary.

First, I had to obtain a nebulizer that would handle a mask. Then I had to acquire the proper glutathione that I could nebulize:

The next step was to acquire the products from resultsRNA, I would not even consider any other brand because my doctor knows how trustworthy the manufacturer is. So, in a small dose cup, I measure out 1/4 teaspoon of the liquid silver, add 1/2 teaspoon of the liquid zeolite. (See lessons learned below). Into this combination, I break open 3 capsules of glutathione and tap out the contents. It fizzles as it dissolves. I take this bubbling liquid and pour it into the nebulizer cup. Then I place the mask over my face and turn on the machine. It takes about 15-20 min. for the liquid to disappear.

I love how simple it is to get the same accurate dose each time. I love that it is easy to adjust dosage according to reaction. I love the fact that nebulizing gets this cocktail into my brain through the sinus/nasal passages when I breathe through my nose. I love that when I breathe this cocktail into my lungs, I know it is getting into my bloodstream. I love bypassing the digestive tract because I tend to overreact to any changes of intake and with this therapy, when done correctly, there should be absolutely no Herxheimer meltdowns. In fact, there should only be positives. Like increased energy, lessened joint pain, increased mental clarity. Decreased inflammation. Better sleep. In my personal case, all the above has occurred. But in addition, I am regaining movement in my fingers. I can lift my left hand, which has been made of concrete for the last three years. My limbs are no longer so spastic and stiff. My caregivers have noticed the amazing alleviation of tension in my muscles. I have only been nebulizing this cocktail for about 5 weeks. I feel like a living miracle. I promise I will write a follow-up in another 5-6 weeks.

I do want to mention a couple of LESSONS LEARNED:

I have found that it is important to start slow, especially with the silver. I have found that the ratio of silver to zeolite is important, that in the beginning I could only tolerate less than 1/8 teaspoon of silver, to 1/2 teaspoon of zeolite. If I tried to take a higher amount of silver, I felt nauseous, shaky, typical die off flulike symptoms. So I had to stay with this combination silver/zeolite, plus the 3 capsules of buffered glutathione for 3 weeks. I am now able to tolerate 1/4 teaspoon silver to 1/2 teaspoon zeolite. I have learned from my doctor that there is absolutely no need to feel anything but better when doing this therapy!
If you have any feelings of being ill, adjust amounts. I was told that sometimes it is wise to nebulize just zeolite for 2-3 days. Drink water.

I have found zeolite to be a diuretic. If I do not stay well hydrated, I experience constipation, headaches, fatigue, heat intolerance.

I have found it beneficial to to take powdered micronized zeolite as well, somewhere between 1/4 teaspoon-1 teaspoon everyday. However, even this I find to be a diuretic and once again I have to stay on top of the water intake.

I have found it useful to take magnesium. Without some extra magnesium, I get extreme muscle/joint pain. I believe this is actually a positive, because as I am removing mercury, lead, cadmium, arsenic, I need to replace these bad guys with nutrient metals like magnesium.
