The Beginning of the Sulfur Story

Published on June 28, 2011


The American Food and Drug Administration, asleep at the switch as usual, has not assigned a minimum daily requirement (MDR) for sulfur. One consequence of sulfur’s limbo nutritional status is that it is omitted from the long list of supplements that are commonly artificially added to popular foods like cereal.

Dr.Gabriela Segura posted an important page on the Internet that introduces something I overlooked in my first report on how to protect oneself from radiation as well as how to treat radiation sickness. We need extra sulfur in our systems to help protect and treat radiation contamination. Segura published that, “Sulfur has a long history of use as an antidote for acute exposure to radioactive material.”

I could probably write a book on sulfur like I did on magnesium, iodine and sodium bicarbonate. Sulfur takes us, like these other basic minerals, down to the very basic structure of life. When we use these common substances as medicines we are treating and addressing the foundations of healthy cell physiology.

In my book New Paradigms in Diabetes I carefully address the issue of disulfide bonds because mercury and other heavy metals like uranium and lead attack these sensitive sulfur bonds. Disulfides dissolved in water are very sensitive to radiation damage. Mercury, in its various forms, all of which have been studied in universities around the world, has shown a great affinity for certain minerals, as well as protein and non-protein molecules in the body.

The science of mercury toxicity shows us that mercurials have a great attraction to the sulfhydryls or thiols. The mercury atom or molecule will tend to bind with any molecule present that has sulfur or a sulfur-hydrogen combination in its structure. A thiol is any organic compound containing a univalent radical called a sulfhydryl and identified by the symbol -SH (sulfur-hydrogen). A thiol can attract one atom of mercury in the ionized form and have it combine with itself. Because it is a radical, it can enter into or leave this combination without any change. Mercury and lead both have a great affinity for sulfur and sulfhydryls and are capable of affecting the transsulfuration pathways in the body. Uranium would be included here because it has the same chemical properties of lead.

The most common mode of breakdown is the sulfur-sulfur bonds. Organic sulfur is an acid-forming mineral that is part of the chemical structure of the amino acids methionine, cysteine, taurine, and glutathione. Sulfur disinfects the blood, helps the body to resist bacteria, and protects the protoplasm of cells. It aids in necessary oxidation reactions in the body, stimulates bile secretion, and protects against the harmful effects of radiation and pollution. It is found in hemoglobin and in all body tissues, and is needed for the synthesis of collagen, a principal protein that gives the skin its structural integrity.

I wrote all about this in New Paradigms in Diabetes because insulin has three sulfur-containing cross-linkages and the insulin receptor has a tyrosine-kinase-containing sulfur bond, which are the preferred targets for binding by mercury, lead and uranium. Should any of these heavy metals attach to one of these three sulfur bonds it will interfere with the normal biological function ofthe insulin molecule.

The average adult inhales thousands of trillions of mercury atoms a day from a mouth full of amalgam, fish provide trillions more, the air more, and in children, vaccines provide one-day surges of trillions of mercury molecules in the form of ethyl-mercury, which is vastly more toxic than metallic mercury. Insulin molecules are directly assaulted as are insulin receptor sites.

If we do not get the correct amount of organic sulfur, or it’s weakened through bonding, it cannot do these four crucial things: (1) facilitate the detoxification of heavy metals, (2) effectively enable the transport of oxygen across the cell membrane, (3) foster healthy cell regeneration, or (4) act as the key agent in the effective utilization of amino acids. Four of the more crucial amino acids, methionine, cystine, cysteine, and taurine, cannot effectively function without organic sulfur.

    Dear Claudia, I know that dr Sircus recommends also oral intake of ancient mineral magnesium. My question is if we can apply same with ancient minerals Ultra oil, MgCl with MSM added. Is it recommended and do you know what is the ratio of MSM to MgCl in this Ultra oil. Thank you. Best regards .

  • Rachel Lazenby, CNC

    To Jess88,
    Sulphur is detoxifying, so you have to start out slow, especially if you have known heavy metal exposure such as amalgam fillings and vaccinations. I usually have people start on 500 mg 1-2 times daily and work up to 4,000 mg per day (with food). If you have a sulfite allergy or intolerance (such as to grapes or wine) it can mean that you have a molybdenum deficiency. Molybdenum taken at low doses would correct that (under 500 mcg).

  • Great article, exactly what I was looking for.

  • Jess88

    I am only 41 and was a relatively healthy person working out 3 days a week. I began taking MSM twice a day in water because I heard of the benefits. I developed tachycardia and complete loss of appetite after starting the MSM. I’m not sure if this is a severe detox reaction and perhaps I have heavy metal poisoning? But now I’m afraid of MSM and other sources of sulfur….

  • Iris

    What if you have an allergy to sulfur, and have had since birth?

    • To Iris,

      A sulfur allergy may not be an allergy to anything containing sulfur. Please see this article explaining :

      where it explains: “Being told that one is “sulfur allergic” commonly causes confusion, as many people wrongly assume that they will be allergic to multiple sulfur-containing medicines or sulfite preservatives. It is important to know that sulfur is an important building block of life, and that allergic reactions to sulfonamide (sometimes called “sulfur”)antibiotics do not increase the likelihood that a person will also be allergic to sulfur powder, sulfite preservatives, or non-antibiotic sulfonamide medicines like some pain killers or diuretics ”
      See the article for further explanation.

  • Mary

    Wouldn’t broccoli and the other crucifers be a source of sulfur?

    • Mary,
      Yes, cruciferous vegetables are a good sourxe of sulfur and are found to be rich sources of sulfur-containing compounds known as glucosinolates. These have been found to be preventative of colorectal cancers, lung cancers and other types.

    • Bill Mcmahon

      Yeah if you eat them raw, and often.

  • is the link on this site still a good company to get MSM from??? Also is the powder form just as good as their crystals???

    • Yes Candy, this is the site we recommend for your organic sulfur needs. The choice is yours as far as crystals or powder…both are fine.

    Mark, how much is enough sulfur in the diet? I have been taking 1-2 grams every day for the past 8 yrs as MSM & not noticed any appreciable difference. I suppose your main supplement use is for detox & not necessarily health supplement as it is naturally occuring in foods.
    Thank you.

    • Claudia – IMVA Staff


      Here is a site with some general instructions on how much sulfur to take. Dr. Sircus cannot give specific dosage recommendations here on his blog but I hope this helps you:

      If you would like more information from Dr. Sircus, please consider a personal consult with him.

  • Bob

    NOW supplement company has a liposomal form of MSM which is very inexpensive:

    • Jay

      They are cheap for a reason. NOW is notoriously low quality and always puts fillers in their products. I avoid them.

  • Isabel

    I live with a form of Multiple Sclerosis that affects my pain & temperature nerve pathways much more than motor nerve pathways. Consequently, I experience much severe, but mercifully, brief pain. I had a major relapse in 2010 – was “locked” in a strait-jacket of pain for many months. Being a retd RN I was worried about the amount of Paracetamol I was taking (though not so much compared with the norm). I found MSM & it has been a wonderful answer for those times when pain becomes less fleeting, more intractable.

    Unfortunately, govt of NZ has made it virtually impossible to obtain DMSO here. Govt., medical profession is shackled to the pharmaceutical corporations. Also, MSM is needlessly expensive & increasingly hard to obtain.

    I “drop” everything when I see your e-letter has arrived Mark. I also send it on asap to my small email list & ask recipients to send it on to family/friends. This way, the gospel of self-health is spread. Thank you.

    • John Hammell

      Try nebulizing MSM, its a lot more economical that way, a little goes a very long way!

  • Dear Dr SIRCUS,

    Thank you so much.

    To answer Johnny’s question, DMSO can do the trick. As well, a preparation maybe not so well knowned in the USA, that works wonders for all kind of functionnal and chronic problems in the joints, the lungs, the kidneys and the liver (as far as detox and bile production and release are concerned), it is the 300 years oil of Haarlem.

    I give you a small instance of the efficiency of this oil (mix of terebentine + “open sulfur” + flaxseed): for most of my life, I have been craking in all of my joints and suffering hayfever. I just took oil of haarlem for a week, and the noise in my joints were gone, as well as reducing by half, the severity of the symptoms of the hayfever.

    Check it out yourself.


  • peggy

    johnny –

    my dog and i use pure msm powder (methylsulfonlymethane) and mix it into distilled water. the link for measurements is below. i add about an ounce of it to my regular water when i take my vitamins or just to a glass of water for drinking. i add a tbsp or two to my dog’s water bowl. hope this helps.


  • Johnny

    How can we get more sulfur into our bodies ? I’ve been to so many different health food stores but I can’t say that I’ve noticed any sulfur supplements on the shelves.

  • Elaine

    Oh, Dr. Mark……I don’t know if you can truly understand how VERY MUCH you and your work are appreciated!
    If I could give you a single dollar for everytime I have felt appreciation for you, and for what you have done, and continue to do for others, you would be……a multi-trillionare!!


    People understand the real truth in things when it is pointed out and taught to us the way you do.
    And it always goes back the basics of what our bodies and our hearts need.

    If we put the good stuff in our bodies, the bad stuff can’t do it’s dirty work. Now if you could just reach those so called “modern doctors” and the FDA….
    (probably not in this life, but you never know)

    Thankyou from my heart.
    I am a better person physically and spiritually thanks to you, my good man.
