Glutathione Against Cancer and Viral Infections

Published on March 22, 2021

"My husband was dealing with stage 4 leukemia, and tests showed he developed multiple myeloma (M spike), yet we’re doing well due in large part to following some of Dr. Sircus’ protocols. My husband self-discharged from the hospital in Oct 2019 after a three-week stay nearly killed him. As a parting present from the hospital, we both developed colds that turned onto bronchitis. Desperate to help him, I kept praying and found Dr. Sircus. Based on an article on his site, we started nebulizing glutathione. It’s changed our life. Not only did it quickly clear the bronchitis, but our health is slowly but consistently improving as we continue to nebulize glutathione. We started with 50 mg and worked our way up to a whole capsule (200 mg). We are now also taking a new oral form of glutathione, bringing our daily dosage up to 500 mg."

"My husband’s oncologist is amazed at his progress. He was literally near death, and now he’s feeling MUCH better, and his blood markers GET BETTER EVERY WEEK. All this during the pandemic! We also take other supplements like Vit D (live near Seattle, so can’t make it from sunlight seven months out of the year), magnesium, selenium, quercetin, zinc, etc. We took most of these supplements before hospitalization but didn’t know about glutathione, so it is definitely critical.”

L-Glutathione Plus

I recommend L-Glutathione Plus for nebulization because it is specifically engineered for enhanced absorption using pharmaceutical grade (OPITAC) reduced L-glutathione and sodium bicarbonate. When mixed with distilled or DI  water or saline solution, Reduced L-Glutathione Plus™ becomes isotonic, making it comfortably ideal for lung, nasal, and other soft tissue contacts. No fillers, excipients, preservatives, or additives.

As we have recently seen, nebulized bicarbonate is effective for COVID patients in ICU with severe lung impairment. Thus this formula would be more than excellent for all lung conditions, including lung cancer, pneumonia, tuberculosis, emphysema, idiopathic pulmonary fibrosis, cystic fibrosis, and lung disease in people with HIV disease.

I have been nebulizing glutathione with baking soda for my chronic bronchitis. I was astounded the first time I used it. I did not have any problems coughing up mucus for 24 hours, and I had a lot less discharge over the next few days.

Glutathione, the most critical antioxidant in the body, is the place where sulfur and selenium meet up to protect us from cancer. The immune system cannot function properly without it, and antioxidants such as vitamins C and E rely on it to work appropriately within the body. The glutathione cancer connection is well established. Patients with cancer, chronic severe illness, AIDS, and over 60 other diseases have reduced glutathione levels. Glutathione plays a specific role in the detoxification of many well-known cancer-causing and cell-damaging substances in our environment.

Treatment Recommendations

Dissolve 1/2 capsule of the glutathione and bicarbonate in 10 milliliters of distilled water for the first treatment. If you feel OK with the first application, then increase the dosage to 1 capsule of glutathione for 10 milliliters of water and build it up to a maximum of 2 capsules. Please notice that this is a reasonably new treatment. Each patient’s dosages should be found by sensitive application, starting with minimum dosages and building quickly, especially if it is urgent. Be sensitive to the recipient’s feelings and reactions (if any) during and after each application. Dosages should be adjusted downward obviously for young children and infants. Suggest 2 or 3 treatments a day. For severe COVID and other critical lung conditions, follow the bicarbonate protocol used by medical researchers in Brazil.

Bicarbonate is excellent but consistently underestimated by doctors and the medical press. In reality, it is the ultimate form of chemo but do not say that to your oncologist, for he might have a stroke. There is nothing like bicarbonate for cancer patients.

Glutathione a Tiger Against Viruses

Supplemental GSH has been studied extensively and seen to inhibit viral production, indicating and being valuable in preventing and treating other hemorrhagic viral infections like dengue.[1]

Glutathione is the most important cellular defense that allows the body to prevent and fight infections and disease. Glutathione plays a crucial role in the immune response, DNA repair, and the detoxification process that neutralizes drugs, chemicals, radiation, metabolic wastes, beats down viruses, bacteria and reduces toxins and carcinogens that are increasingly present in our environment.

Glutathione (GSH) and the GSH-replenishing enzymes keep the antioxidant status of normal cells at a level where they can avert oxyradical-derived mutations. When we talk about sulfur pathways and sulfur sufficiency, we are at the same time touching on Glutathione because Glutathione is a sulfur enzyme.[2]

Glutathione is manufactured by every one of our trillions of cells, and the level of glutathione in our cells is predictive of how long we will live. Without the cleaning and chelating work of glutathione (magnesium and sulfates needed), cells begin to decay as cellular filth, and heavy metals accumulate – excellent environments to attract deadly infections. Without sufficient GSH, the body accumulates toxins and acid residues, degenerates rapidly, ages prematurely, and dies more easily from viral and bacterial infections.

Over 98,000 scientific studies and articles on glutathione are recorded in PubMed, the official U.S. Government library of medical research. Those articles reveal the remarkable role glutathione plays in every cell’s protection and function in the human body and the support of optimal health and function. They also show the terrible consequences of low glutathione levels and how those lower levels accelerate the aging process.


Glutathione is a sulfur-based enzyme and can float up to anything and attach itself to it. It is like sticky flypaper. Whatever GSH attaches itself to cannot escape and is removed from the body. GSH is our body’s natural scavenger. It knows what is normal and belongs and what does not. Like bacteria, viruses, and fungi, anything that is not normal will be removed if enough GSH present to do the job.

The first step in anti-viral or bacterial medicine is to build the strength of the immune system. Our immune cells are designed to protect us, but what protects the immune cell? Glutathione is the protector of the immune cell and allows newly formed immune cells to proliferate to attack germs and viruses. Glutathione feeds, protects, and strengthens our immune system.

Glutathione boosts white blood cell production to fight infection, particularly the T-cells, which are called lymphocytes. T-cells are at the core of our immunity and tailor the body’s immune response to pathogens, viral and bacterial infections, or anything the cells recognize as invasive. Studies have shown that glutathione is food for the immune cells, boosting the strength of lymphocytes. B-cell lymphocytes identify the unwanted pathogen that the T-cells then attack.

GSH protects us from viruses, such as the herpes virus, flu viruses, and probably from Ebola. Our white blood cells are cells that help fight off viruses. They need an abundant supply of glutathione to protect us from invading micro-organisms and viruses effectively. Inhibition of cellular respiration, oxidation of glutathione, and apoptosis induction have been reported in epithelial cells infected in vitro with influenza A virus (IAV).[3]

This is the strongest Glutathione 1.5 (1,500mg reduced glutathione) available. Ingesting glutathione does not easily raise normal glutathione levels since it is poorly absorbed through the digestive system. The fragile tripeptide (3-amino acid) structure of glutathione makes surviving the digestive tract a near impossibility. This is why using the above suppositories brings excellent results, as does Glutathione I.V.s.

IV glutathione is used to treat diseases related to the brain (Parkinson’s, Alzheimer’s, M.S.), liver (alcoholism), or help those with suppressed immunity (HIV or patients undergoing some chemotherapies like cisplatin).

Healthcare providers give glutathione intravenously for preventing "tired blood" (anemia) in kidney patients undergoing hemodialysis treatment, preventing kidney problems after heart bypass surgery, treating Parkinson’s disease, improving blood flow, and decreasing clotting in individuals with "hardening of the arteries" (atherosclerosis), treating diabetes and preventing toxic side effects of chemotherapy.

Dr. Julian Whitaker writes, "Alpha-lipoic acid also ramps up glutathione synthesis and significantly enhances detoxification, and we use it at the clinic, along with selenium and silymarin, to treat hepatitis and other liver diseases. Recent research suggests that the "sleep hormone" melatonin boosts glutathione status, too, by stimulating the production of the antioxidant enzyme glutathione peroxidase. We’ve had particularly good success in treating patients recovering from strokes and those with hepatitis, neurodegenerative disorders such as Parkinson’s disease, and other chronic illnesses—conditions associated with dramatic increases in oxidative stress depletions in glutathione. IV glutathione isn’t a slam-dunk, and it’s always used in conjunction with hyperbaric oxygen and other therapies, but we’ve seen remarkable improvements, particularly in patients who’d been told that nothing else could be done."

The pre-cursors of glutathione synthesis are the amino acids glutamate, glycine and cysteine, with cysteine being the most important amino acid. As people age or experience disease, glutathione levels in the blood decrease, causing a reduction in this life-sustaining antioxidant. Dietary sources of glutathione are therefore necessary to replenish stores and avoid losses.

Magnesium and Glutathione

Glutathione requires magnesium for its synthesis.[4] Glutathione synthetase requires a-glutamyl cysteine, glycine, ATP, and magnesium ions.[5] Data demonstrates glutathione’s direct action both in vivo and in vitro to enhance intracellular magnesium and a clinical linkage between cellular magnesium, GSH/GSSG ratios, and tissue glucose metabolism.[6]

According to Dr. Russell Blaylock, low magnesium is associated with dramatic increases in free radical generation and glutathione depletion, which is vital since glutathione is one of the few antioxidant molecules known to neutralize mercury.

Nebulized Hydrogen Peroxide

This essay is about glutathione, but because it promotes nebulization, I share the below testimony of another natural substance, namely H2O2 (Hydrogen Peroxide).

I am so angry about this! I’m 62 and came down with pneumonia. I went to my local urgent care only to be turned away, having them tell me, "come back when I’m worse." Are they kidding me!! So I called my lung doc, and she said she’d call in an antibiotic. That was on a Sat. I called the pharmacy, nothing. I called my doc again Monday, and they finally called something in by the following Wednesday. By now, it was over ten days with no treatment, and I’d started to cough up blood. I mean a lot of fresh blood that looked like it came from a vein, not sputum. I immediately started to nebulize food-grade hydrogen peroxide. The bleeding stopped by the next day. I took high doses of Vit, C, D3, A, and zinc. It took a few days, but I started to feel much better. But now I’m dealing with candida. I’d called my doc about getting some Diflucan but thought better of it, so now I’m nebulizing baking soda.

Nebulization – Transdermal Treatments Into the Lungs

The great strength of nebulizers is their ability to deliver medications and moisture directly to the tracheobronchial tree. Contrary to other treatment options, higher concentrations in respiratory secretions can be achieved with aerosol therapy. With the use of this localized delivery system, effective antimicrobials can have a direct effect on surface organisms in the bronchial system.

1) Nebulization thins secretions & mucus, making it easier to expel pulmonary secretions
2) Nebulization makes coughing easier while lessening the need to cough
3) Nebulization keeps your windpipe & trachea lining and stoma moist & healthy
4) Nebulization moistens the air that goes into your lungs
5) Nebulization hydrates & moisturizes your nasal passages, mouth, and throat

Nebulizers are suitable for young children, people who have trouble using metered dose inhalers, and people who have severe asthma. Even babies can breathe the mist, and nebulizer treatments are fast becoming pediatrician-approved alternatives to over-prescribed antibiotics. For pediatricians and parents, nebulizers are a Godsend because our babies cannot pop pills. Transdermal medicine offers the most to the world of pediatrics with the administration of drugs through their baths and their breathing.
