How To Raise Glutathione Levels

question mark

After my husband and I learned about Glutathione (GSH) the next logical question was how to raise Glutathione levels, and most importantly how to do it safely, naturally and with long-term effect. What we learned has benefited our health and our family greatly.

Wisdom comes from answers, and answers are only obtained by asking questions, so ask lots of questions. The better the question, the greater the wisdom gained from the answer. When you have found the answer to how to raise Glutathione, you will have gained some invaluable wisdom into how to live a healthier life.

People who are in good health can benefit from raising Glutathione, too. These days we are exposed as never before to environmental toxins and newly emerging drug-resistant bacteria. When people lose healthcare benefits and disease prevention becomes urgent, it is essential to learn how to raise Glutathione effectively. The more we learn how to raise Glutathione and implement what we learn, the fewer visits we make to the doctor and the more control we take over our health.

It took time and a lot of questions before my husband and I both understood that Glutathione was the hope and the answer that doctors could not give us. Once we realized this, it was time to find out how to raise Glutathione levels. What we learned on our journey is presented on this page. So, let's get started.

Substances promoting Glutathione production can be divided into three categories: natural products, cofactors of Glutathione production and pharmaceutical drugs.


HOW TO RAISE GLUTATHIONE WITH NATURAL PRODUCTS



Oral Glutathione - if our bodies depend on Glutathione for so many important protective functions, what can be easier than eating it? But before you run to a health food store you should know that, unfortunately, oral Glutathione is useless as most of it gets broken down in the digestive system and does not reach cells. Only very small amounts of Glutathione make it into the bloodstream. One study showed an increase in plasma GSH after administering dietary Glutathione to rats with chemically inhibited Glutathione synthesis; however, no increase in liver was observed where it is most needed since liver is the largest and most important detoxifying organ.


Medical Symbol Researchers have proved that the bioavailability (usefulness) of oral Glutathione is very low, and in this form it cannot seriously affect immune health.

Read the abstracts of the studies confirming ineffectiveness of raising Glutathione with oral or dietary GSH.




In a recent study “Effects of oral glutathione supplementation on systemic oxidative stress biomarkers in human volunteers” published in September 2011 in the Journal of Alternative and Complementary Medicine researchers from Bastyr University Research Institute, Kenmore, WA, examined the effect of oral glutathione supplementation on biomarkers of systemic oxidative stress in 40 healthy adult volunteers. This was a randomized, double-blind, placebo-controlled clinical trial. There were no differences in oxidative stress biomarkers between treatment groups at baseline. One group of volunteers took 500 mg of oral glutathione supplement twice daily for 4 weeks, another group received placebo. At the end of the study total reduced glutathione (GSH), oxidized glutathione (GSSG), and the ratio of GSH to GSSG (indicator of oxidative stress) remained unchanged in both groups compared to the results obtained before supplementation. It was concluded that no significant changes were observed in biomarkers of oxidative stress, including glutathione status, in this clinical trial of oral glutathione supplementation in healthy adults.

broccoli Foods - Cyanohydroxybutene, a chemical found in broccoli, cauliflower, Brussels sprouts and cabbage, and chrolophyll in parsley are thought to contribute to raising Glutathione levels. Various herbs - for instance cinnamon and cardamom - have compounds that can assist in restoring healthy levels of GSH. However, research on these foods' role in Glutathione production is very limited. Glutathione is present in fruit, vegetables and meats. But dietary Glutathione, just like oral Glutathione supplements, gets broken down in the digestive tract and cannot enter cells.

Methionine – an essential amino acid present in many foods and required for production of cysteine which is one of the three building blocks for Glutathione. Methionine is available from health food stores, too. Of great concern is the fact that methionine is also a precursor of homocysteine identified as a high risk factor in atherosclerosis (hardening of arteries).

Lipoic acid (alpha-lipoic acid) - a disulfide compound with several functions: it acts as an antioxidant, it neutralizes several toxins including heavy metals lead and cadmium, it acts as a co-enzyme for recycling other antioxidants including Glutathione and also vitamins C and E. Lipoic acid is produced in the body but also available as a supplement. It plays an important role in converting Glutathione back and forth from its oxidized form to its reduced or non-oxidized form (GSH). This ability of lipoic acid to enhance Glutathione function leads to improved levels of GSH in cases of Glutathione deficiencies – most known diseases show Glutathione deficiencies especially in their chronic state. Recommended dosages of supplemental lipoic acid are 100 to 200 mg/day.

Glutamine - free amino acid found in the body in abundance. It is common in blood, muscles and the brain. Glutamine is very closely related to glutamic acid (glutamate) – second most important Glutathione precursor after cysteine. Glutamine and glutamate have the ability to metabolize into one another which means glutamine supplies the body with glutamate – that is an important function. The studies have shown that when taken orally or intravenously glutamine raises Glutathione concentrations. Glutamine is crucial to the metabolism and maintenance of muscles. It serves as a primary nutrient for the cells of the GI tract lining; supports liver metabolism and function; can boost the immune system – all due to its ability to promote Glutathione production. One study led by Dr. Rouse of University of Arkansas showed that glutamine as a supplement was able to lower Glutathione levels in tumors making them more susceptible to chemotherapy while raising Glutathione in healthy cells making them more resistant to such harsh cancer treatments. Glutamine is abundant in plants and meats but gets easily destroyed by cooking. Good sources are fresh parsley, spinach and sushi with uncooked fish (make sure the restaurant is reputable and serves quality fish). Glutamine supplements vary in dosages from 500 mg to 5,000 mg. They come in pill or powder form, and are often labeled "L-glutamine". Supplemental glutamine can lead to gastrointestinal side effects. Elderly and patients with kidney and liver diseases should be very cautious when taking this supplement. The use of supplemental glutamine, especially long-term, should be monitored by a doctor.


tart cherry juice Melatonin – a hormone known to regulate sleep and waking cycles, produced by the pineal gland in the brain. Melatonin is released into the blood at night time and its production is affected greatly by light. Melatonin is also a powerful antioxidant and plays a role in stimulating other antioxidants as well. Melatonin has been shown to effectively raise GSH levels in many tissues including those of the brain, liver, muscle and blood serum. The only known viable natural source of melatonin is sour (tart) cherries, especially the Montmorency variety, which contain substantial amounts of melatonin, enough to produce a positive effect in the body and without any side effects unlike the synthetic form.

Milk Thistle - a plant used by herbalists for many centuries to treat various liver disorders as it seems to stimulate the growth and regeneration of injured liver cells. The active component of milk thistle called silymarin prevents lipid peroxidation of GSH and maintains its levels. Recommended dosages vary quite a bit from 50 to 500 milligrams three times a day. Toxic reactions can develop with overdose: cramps, gas and diarrhea. Milk thistle should not be used without a professional medical advice.

Cysteine - an amino acid that is required for the production of Glutathione directly in the cells - that's where Glutathione is most needed and produced by the body itself. Cysteine is usually the limiting factor in the production of Glutathione because of its shortages. Cysteine can be found at health food stores as a supplement but consumed this way it can promote hypercysteinemia (homocysteinemia) and potential toxicity. It is also present in many fruits, vegetables, meats and eggs bonded with other amino acids to form proteins, however, it gets destroyed by cooking. Most cysteine from raw produce does not survive the trip from the stomach to cells either. The cysteine that does survive is quickly eaten up by the bacteria in our intestinal tract - all living organisms use cysteine, so it is useful in that it helps our flora to stay healthy.

Raw milk (raw dairy) - this option of how to raise Glutathione belongs in the food category. But the uniqueness of this food deserves special attention. Raw milk whey contains powerful Glutathione precursors - lactoferrin, beta-lactalbumin and serum albumin. They are very easily denatured by heat and mechanical stress during pasteurization and homogenization of milk. After digestion the products of these compounds' breakdown pass readily into the bloodstream, serving as cysteine and cysteine delivery systems, thus enabling cysteine to get into the cells for Glutathione production. This is how our ancestors used to get their cysteine from diet before pasteurization became mandatory. How to raise Glutathione with raw milk? There are three problems: first, you have to have free access to a raw dairy farm; second, you have to be sure the farm delivers safe raw milk free of pathogens; third, to raise Glutathione levels noticeably you will have to drink at least 2 gallons of raw milk a day which is impossible to do. But adding raw milk to the diet is still a good idea: you do get some bioavailable cysteine this way, just not in sufficient quantities.

Find a raw milk dairy in your area.


Undenatured whey proteins - not all whey proteins are made in the same way. Whey proteins that are manufactured from raw milk using the process of cold filtration and segmentation (removal from other agents in milk) leave the final product undenatured or unaltered. As a result, a cysteine molecule is actually double bonded with another cysteine molecule and is now called cystine (note the difference in spelling). Cystine in this manner is resistant to stomach acid breakdown and freely flows across the intestinal wall into the blood. Cystine enters the cells and separates back into two cysteine molecules - exactly where we want it to be. Undenatured whey proteins preserve the original bioactivity of cysteine guaranteeing the highest level of Glutathione promoting activity.

Dr. Gustavo Bounous

This unique quality of undenatured whey proteins was discovered as a result of research done by Dr. Gustavo Bounous at the McGill University in Montreal, Canada, in the early 1980s. He investigated undenatured proteins’ effect on the immune system and published very exciting results.








Immunocal Dr. Bounous and his team went on to develop Immunocal – an undenatured whey protein with bonded cysteine made under conditions to maximize the protein’s bioactivity. It actually takes 1 gallon of raw milk to produce one pouch of Immunocal.

Immunocal has received patents for its immuno-sustaining and glutathione-enhancing effects. This natural supplement is a safe dependable way to raise and sustain Glutathione levels.

There are many reasons why I believe Immunocal is the best answer to how to raise Glutathione levels. Here are a few of them:

  • Immunocal is the only natural product listed in the Physicians’ Desk Reference (PDR) and the Pharmacist’s Red Book;

  • it is patented in the U.S. as an anti-cancer therapeutic composition;

  • it is clinically proven to raise Glutathione levels by 35.5% safely and naturally and maintain these levels;

  • it is classified by the FDA as "GRAS" (generally regarded as safe) and has no known side effects;

  • it is one of the very few natural products that is safe for infants 10 lb. and up;

  • and most importantly, it made a tremendous difference in managing Ray's pain and numbness from his peripheral neuropathy, and in increasing his energy levels to where he could resume working full days in the office again without passing out from exhaustion. Between August 2011 and April 2012 he has been away on business trips for 10 to 14 days a month, every month. Our search for how to raise Glutathione effectively and naturally has not ended with the discovery of Immunocal, but to date nothing we have researched has surpassed the benefits gained from taking Immunocal.


This amount of evidence is convincing enough for me to make the statement that Immunocal is THE BEST natural product on the market for raising Glutathione levels.



HOW TO RAISE GLUTATHIONE WITH COFACTORS

Lemon Vitamins - in one trial, blood GSH levels rose nearly 50% in healthy people taking 500 mg of vitamin C per day for only two weeks. Vitamin C raises Glutathione by helping the body manufacture it.

Vitamin E acts in a similar way as vitamin C - it recycles Glutathione and depends on it for proper function and recycling as well.

Vitamins B6, B12, B1 and B2 are also required in the synthesis of Glutathione. B1 and B2 maintain Glutathione and its related enzymes in their active forms. B2 helps combine amino acids into proteins, and Glutathione is one of them. B6 is crucial for the metabolism and proper function of many amino acids, for example, for converting homocysteine into cysteine. B12 acts as a coenzyme in the production and regulation of red blood cells.

Folate or folic acid (known as B9) - its role as Glutathione booster lies in folate’s ability to divert cysteine preferentially towards Glutathione production rather than homocysteine production, thus helping supply the cells with more cysteine for building intracellular Glutathione. Maximum recommended dosage of folate is 400 mcg/day. Best dietary sources are spinach, turnip greens, lettuce, dried beans and peas, sunflower seeds, peanuts, avocado, asparagus, fortified pastas and cereals. When cooking veggies they should be steamed instead of boiled – less folate leaches into the water this way.

Selenium - the trace element that functions as an antioxidant. It also participates in protein synthesis and other metabolic processes and acts together with other antioxidants, especially vitamin E. Selenium elevates the levels of glutathione peroxidase; the cysteine molecule appearing in the process of digestion of plants grown in selenium-rich soil contributes to GSH production. Recommended Daily Intake (RDI) for adults is 55 mcg. Best dietary sources are Brazil nuts, sunflower seeds, oatmeal, tuna, turkey, chicken breast, beef, eggs and brown rice.

Magnesium - magnesium is necessary for proper functioning of enzyme gamma glutamyl transpeptidase which is important in the synthesis of Glutathione. RDI is 400 mg, but optimum daily intake is considered at 490- 700 mg. Best dietary sources are halibut, spinach, squash, pumpkin seeds, sunflower seeds, toasted sesame seeds, beans, walnuts, almonds, peanuts and Brazil nuts.

Zinc - zinc deficiency leads to low concentrations of reduced (non-oxidized) Glutathione, especially in red blood cells. This is detrimental to Glutathione metabolism. However, high levels of zinc may reduce Glutathione because zinc has a certain toxicity. RDI for adults is 8-11 mg. Best dietary sources are oysters, beef shanks, chicken legs, pork shoulder and tenderloin, and Alaskan King crab. Zinc from beans, legumes and grains has very low bioavailability compared to meat sources.

Vanadium - this element depends on Glutathione to stay in non-oxidized state and to increase vanadium’s bioavailability. It may even recycle Glutathione under certain conditions. At high levels vanadium may deplete glutathione due to its toxicity. Vanadium’s role in health has not been studied very well, so there is no RDI established. Average diet provides 6-18 mcg a day. Safe upper limit is 1.8 mg (1,800 mcg). Dietary sources are: mushrooms, shellfish, dill, parsley and black pepper.

Adequate amounts of vitamins C, E, B1, B2, B6, B12, folate, selenium, magnesium and zinc, either from diet or with additional supplementation, are necessary for raising Glutathione levels.


HOW TO RAISE GLUTATHIONE WITH DRUGS



syringe, pills NAC – N-acetyl-cysteine - is a potent glutathione precursor that has been available as a drug (Mucomist, Parvolex etc.) and also can be found on the shelves of health food stores marketed as a glutathione booster.

Some people taking NAC report rash, wheezing, nausea, vomiting, cramps and diarrhea. NAC is widely used in hospital emergency rooms, usually intravenously, on patients suffering from severe acetaminophen toxicity due to Tylenol overdose in order to quickly spike their glutathione levels and save their lives. These measures often lead to above-mentioned side effects, sometimes resulting in death from complication if there are underlying health conditions such as asthma.

Also, raising GSH levels with NAC has only temporary effect lasting mere hours which requires taking it often to maintain Glutathione levels throughout the day. My advice is to stay away from NAC supplements or any supplements containing NAC as an ingredient.

SAM – S-adenosyl-methionine - is a form of methionine already partially converted into cysteine, it can be useful in the treatment of cirrhosis and cholestasis and is becoming popular in Europe as a mood stabilizing medication. SAM is a drug and cannot be used as a safe and natural method of raising glutathione.

OTC & OTZ – these are synthetic cysteine delivery systems. These drugs are not readily available to doctors or the general public.


HOW TO RAISE GLUTATHIONE BY NOT DEPLETING IT



Glutathione is depleted by a very large number of substances. Some can be avoided, some cannot. Understanding what depletes Glutathione and reducing your exposure to these "offenders" makes your efforts in raising Glutathione levels more effective.

Knowing how to raise Glutathione is very important, but it is also wise to know

what depletes Glutathione.



HOW TO RAISE GLUTATHIONE: CONCLUSIONS



Some of the most important points of this research are:

  • Elevated levels of Glutathione promote long healthy lives that are more resistant to diseases. All clinical studies reviewed showed that raising Glutathione is of great benefit to the human body.

  • While there are many options of how to raise Glutathione, the most effective, with the least side effects, appear to be undenatured whey protein with bonded cysteine (Immunocal), melatonin in its natural state in tart cherries, lipoic acid, glutamine and milk thistle.

  • Immunocal supplies cysteine - the most essential of the three Glutathione precursors; it also maintains elevated Glutathione levels, while natural melatonin, lipoic acid and milk thistle provide only temporary effect and act more as enhancers of Glutathione function.

  • Glutamine can be converted into glutamate - the second most important Glutathione precursor, and thus it plays a significant role in Glutathione metabolism.

  • All cofactors of Glutathione production (vitamins C and E, B vitamins, folate, selenium, magnesium and zinc) are necessary in sufficient quantities. Their deficiencies are detrimental to Glutathione metabolism.

  • It is just as important to know how not to deplete Glutathione as it is to know how to raise Glutathione.


Hopefully, you now have some answers to the question of how to raise Glutathione. Specifically, you should have some answers on how to raise Glutathione levels with natural products, with cofactors and with drugs, and also pros and cons of each of these options. You should have also gained some wisdom concerning how to raise Glutathione, and wisdom is more valuable than gold.
