Sulfur is a considerably “forgotten” nutrient you do not hear talked about fairly often, however it’s crucial for optimum physique perform and well being. You get most of your sulfur from sure proteins in your weight-reduction plan, particularly the amino acids methionine, cysteine, cystine, homocysteine, homocystine and taurine.1
Of those, the 2 most essential sources are methionine and cysteine. Methionine is a necessary amino acid, which suggests it can’t be synthesized by your physique and should be provided by way of your weight-reduction plan. Cysteine is conditionally important, as a result of it may be synthesized from methionine however not from inorganic types of sulfur.2
Neither of those main sulfur-containing amino acids is saved in your physique per se, though glutathione is a key storage kind for sulfur.3 Glutathione consists of three amino acids: cysteine, glutamate and glycine, and is your physique’s most potent antioxidant.
Glutathione additionally retains many different antioxidants acting at peak ranges, and cysteine availability is regarded as a rate-limiting issue for glutathione synthesis.4
Whereas sulfur is discovered in lots of meals, sulfur deficiency should still be fairly frequent5 — partially as a consequence of sulfur deficiency in crops,6 and partially as a consequence of low consumption of sulfur-rich meals7 reminiscent of leafy greens, cruciferous veggies, alliums8 reminiscent of garlic and onions, seafood, grass fed meats and natural pastured eggs.
Frequent use of medicine that require sulfur for excretion and/or detoxing may contribute to an insufficient sulfur standing. Acetaminophen is one such instance.9 A vegan weight-reduction plan may put you at elevated danger for sulfur deficiency, as a result of plant-based meals comprise fewer sulfur-containing amino acids than animal-based meals.10
The Significance of Sulfur
Based on Stephanie Seneff, Ph.D., who has written a number of papers11,12,13,14 on sulfur and sulfur metabolism and its position in human illness, sulfur performs a task in lots of organic processes, together with metabolism15 and the sulfonation of hormones,16 and deficiency seems to play a task in a variety of well being issues and illnesses, together with:
- Weight problems
- Coronary heart illness
- Persistent fatigue syndrome
- Alzheimer’s illness
- Autism17
Required within the creation of connective tissues reminiscent of cartilage, tendons and ligaments, sulfur can be important for wholesome joints, and deficiency has been linked to joint ache and joint-related illnesses.18 Different advantages, makes use of and sources are additionally famous within the paper “Sulfur in Human Vitamin and Functions in Drugs”:19
“Methylsulfonylmethane (MSM), a unstable part within the sulfur cycle, is one other supply of sulfur discovered within the human weight-reduction plan … Natural sulfur, as SAAs [sulfur-containing amino acids], can be utilized to extend synthesis of S-adenosylmethionine (SAMe), glutathione (GSH), taurine, and N-acetylcysteine (NAC).
MSM could also be efficient for the therapy of allergy, ache syndromes, athletic accidents, and bladder problems.
Different sulfur compounds reminiscent of SAMe … taurine, glucosamine or chondroitin sulfate, and decreased glutathione can also have scientific functions within the therapy of quite a lot of situations reminiscent of despair, fibromyalgia, arthritis, interstitial cystitis, athletic accidents, congestive coronary heart failure, diabetes, most cancers, and AIDS.”
Sulfur 101
As defined by the featured examine above, sulfur is the third most plentiful mineral in your physique, primarily based on proportion of complete physique weight.20 Sulfur bonds are required for proteins to take care of their form, and these bonds decide the organic exercise of the proteins.
For instance, hair and nails encompass a troublesome protein referred to as keratin, which is excessive in sulfur, whereas connective tissue and cartilage comprise proteins with versatile sulfur bonds, giving the construction its flexibility.
With age, the versatile tissues in your physique are likely to lose their elasticity, resulting in sagging and wrinkling of pores and skin, stiff muscle groups and painful joints. A scarcity of sulfur possible contributes to those age-related issues.
Along with bonding proteins, sulfur can be required for the correct construction and organic exercise of enzymes. If you do not have enough quantities of sulfur in your physique, enzymes can’t perform correctly.
A cascade of well being issues could thus ensue, since your metabolic processes depend on biologically lively enzymes. You may be taught extra about this in “Enzyme Fundamentals.” Sulfur additionally performs an essential position in:
|
Your physique’s electron transport system, as a part of iron/sulfur proteins in mitochondria, the vitality factories of your cells21 |
|
Synthesizing essential metabolic intermediates, reminiscent of glutathione — some of the essential antioxidants that your physique produces — SAMe, taurine and NAC22 |
|
Detoxing23 — With out sulfur, glutathione (your physique’s built-in detoxifier) is rendered ineffective |
|
Thiamine (vitamin B1) and biotin (B7) conversion, which in flip are important for changing carbohydrates into vitality |
|
Correct insulin perform24 — The insulin molecule consists of two amino acid chains related to one another by sulfur bridges, with out which the insulin can’t carry out its organic exercise25 |
|
Glucose metabolism — One speculation26 is that if a enough quantity of sulfur is obtainable, it should act as a decoy to glucose, successfully diverting it to cut back the sulfur moderately than glycating and inflicting harm. This is able to have the useful impact of decreasing power irritation, as sugar (glucose) is very inflammatory and wreaks havoc in your physique |
Sulfur for Liver Well being
Sulfur can be essential for wholesome liver perform and the prevention of liver illness. As famous in a single examine,27 “a derangement in sulfur amino acid metabolism, presumably positioned at numerous steps alongside the trans-sulfuration pathway” is discovered even in delicate types of liver illness.
A part of its affect in your liver has to do with its affect over glutathione. As famous within the 2015 paper,28 “Metabolism of Sulfur-Containing Amino Acids within the Liver: A Hyperlink Between Hepatic Harm and Restoration”:
“The transsulfuration pathway is related to the manufacturing of glutathione (GSH), which has potent antioxidant capability within the liver. Accumulating knowledge present that GSH depletion renders the liver weak to oxidative stress and vulnerable to development of liver illness.”
Equally, the journal Vitamins studies that MSM has been proven to attenuate “cytokine expression in vivo for induced colitis … and liver damage,” and that MSM has additionally been proven to have a useful impact on liver most cancers.29
One other essential nutrient for liver well being and the prevention of power liver illness, together with nonalcoholic fatty liver illness, is choline,30 detailed in “Choline Is Essential for Liver Well being.”
MSM for Osteoarthritic Knee Ache
Methylsulfonylmethane (MSM) is named a sulfur donor, being 34% elemental sulfur by weight.31 Most of the advantages of MSM supplementation are associated to its potential to cut back irritation, regulate the steadiness of reactive oxygen species and antioxidant enzymes,32 and modulate your immune response.33
As a complement, MSM is broadly used within the therapy of ache, particularly ache related to arthritic situations. One scientific trial34 discovered that individuals with osteoarthritis of the knee who took 3 grams of MSM twice a day for 12 weeks skilled considerably decreased ache and improved bodily perform, in comparison with a placebo.
One other randomized double-blind placebo-controlled examine35 discovered sufferers with delicate to reasonable osteoarthritis benefited from oral glucosamine and MSM, each individually and together. Right here, the therapy teams acquired 500 milligrams (mg) of glucosamine and/or 500 mg of MSM 3 times a day for 12 weeks. Based on the authors:36
“Glucosamine, MSM and their mixture produced an analgesic and anti inflammatory impact in osteoarthritis. Mixture remedy confirmed higher efficacy in decreasing ache and swelling and in enhancing the practical potential of joints than the person brokers.
All of the remedies had been effectively tolerated. The onset of analgesic and anti inflammatory exercise was discovered to be extra speedy with the mix than with glucosamine. It may be concluded that the mix of MSM with glucosamine supplies higher and extra speedy enchancment in sufferers with osteoarthritis.”
Sulfur’s Function in Coronary heart Illness
In 2011, I interviewed Seneff concerning the affect of sulfur on well being and illness. I’ve included that interview above to your comfort. In it, Seneff discusses the essential connections between sulfur, ldl cholesterol and vitamin D.
Her analysis suggests coronary heart illness may very well be associated to ldl cholesterol sulfate deficiency, and within the interview, she explains how elevated LDL (low-density lipoprotein) ldl cholesterol is an indication of this deficiency.
To summarize, excessive ranges of LDL ldl cholesterol is your physique’s method of compensating for ldl cholesterol sulfate deficiency. When LDL is changed into plaque, blood platelets contained in the plaque produce ldl cholesterol sulfate, which your coronary heart and mind want for optimum perform.
Seneff additionally explains why decreasing LDL with statins can result in coronary heart failure. Primarily, by elevating LDL, your physique is defending itself from the dangerous results of ldl cholesterol sulfate deficiency. If you merely take away the LDL, you take away this “backup” mechanism geared toward preserving your coronary heart going robust. Because of this, coronary heart failure turns into a definite risk.
That mentioned, excessive LDL is correlated with heart problems, so the query then turns into: How can your physique produce ldl cholesterol sulfate with out having to create dangerous LDL?
Below regular, wholesome situations, your pores and skin synthesizes each ldl cholesterol sulfate and vitamin D3 sulfate when uncovered to daylight. These two sulfated sterols are water soluble and may journey freely in your bloodstream.
If in case you have enough quantities of ldl cholesterol sulfate in circulation, your physique doesn’t want to supply extra cholesterol-transporting LDL. This leads to much less plaque buildup within the arteries of the guts, as a result of ldl cholesterol sulfate is plentiful.
In essence, wise solar publicity could also be an essential a part of coronary heart and cardiovascular well being. The truth is, research have proven that those that reside in nations with plentiful daylight have a decrease danger to coronary heart illness. Vitamin D3 dietary supplements, however, are unsulfated. It is a vital disadvantage, because the unsulfated kind wants LDL as a car of transport.
Seneff believes that vitamin D is mainly a signaling molecule that informs the tissues that there’s an plentiful provide of ldl cholesterol sulfate, and ldl cholesterol sulfate is the true useful product of daylight publicity to the pores and skin. Her suspicion is that the oral nonsulfated type of vitamin D is unlikely to offer the identical advantages because the vitamin D created in your pores and skin from solar publicity, since it’s not accompanied by ldl cholesterol sulfate, and subsequently supplies a false sign.
Sulfur Intolerance Might Be a Signal of Toxicity
As talked about earlier, sulfur-rich meals37 embody leafy greens, cruciferous veggies, alliums,38 seafood, grass fed meats and natural pastured eggs. One other glorious supply, and maybe one of the best one, is home made bone broth comprised of organically raised animals.
Both drink the broth commonly, or use it for soups and stews. Connective tissues are sulfur-rich, and once you slow-cook the bones, you dissolve these vitamins out of the bone and into the water.
If in case you have poor tolerance for meals excessive in sulfur, it might be a sign of an overgrowth of sulfur-reducing micro organism in your intestine. These micro organism, reminiscent of Desulfovibrio and Bilophila wadsworthia, produce hydrogen sulfide fuel from sulfur-based meals sources, which might destroy the intestine lining and trigger gastrointestinal discomfort.
A defect within the enzyme that oxidizes sulfur to sulfate, referred to as sulfite oxidase, will result in an overgrowth of those sulfur-reducing micro organism, and poisonous chemical exposures could disrupt sulfite oxidase.
Moreover, these micro organism additionally convert mercury to a poisonous natural kind referred to as methyl mercury. When sulfite oxidase is poor, mercury can’t be transformed to mercury sulfate, which is the unhazardous type of mercury that may be excreted by the physique. Thus, disruption of sulfite oxidase leads to impaired sulfation capability and elevated mercury toxicity.
Different meals components reminiscent of meals dyes may exacerbate issues in your phenol sulfur-transferase (PST) sulfation pathway by suppressing PST enzyme exercise. Sulfation is a important step in detoxing of poisonous phenols.
To deal with this case, it is beneficial you initially go on a low-sulfur weight-reduction plan and cut back your poisonous publicity by consuming natural and avoiding family toxins of all types.
As your toxicity degree is decreased, you can begin including sulfur-rich meals again into your weight-reduction plan, separately. Subsequent, it is essential to boost your physique’s detoxing course of by supplying extra sulfate, both by way of weight-reduction plan or supplementation.
Find out how to Increase Your Sulfur Consumption — Weight loss plan and Supplementation
Apart from sulfur-rich meals, sulfur may also be obtained by way of supplementation with MSM. You may be taught extra about MSM in my interview with Rod Benjamin.
Benjamin is the director of technical growth for Bergstrom Vitamin, the most important producer of the best high quality MSM produced by distillation purification. In his interview, we focus on recommended dosages and methods to establish a high-quality complement.
The sulfur-containing amino acids cysteine and taurine may also be used, each of which can be found in complement kind. The complement type of cysteine is NAC.
One other glorious supply of sulfur is taking common Epsom salt baths. Epsom salt (magnesium sulfate) is made up of magnesium, sulfur and oxygen. Whereas a lot of the advantages related to Epsom salt baths pertains to magnesium39 — reminiscent of improved sleep, stress discount and decreased ache and muscle cramping — its sulfur content material can be essential for well being.
Epsom salt baths are sometimes preferable when you’re poisonous, because the sulfur in Epsom salt is available to your physique with out having to be transformed. As a common advice, use 1 to 2 cups of Epsom salt to a bathtub of water. The hotter the water, the extra of the salt that will probably be dissolved, and the extra your physique will be capable to take in as the warmth opens your pores.
In case you expertise a damaging response, reminiscent of irritability or hyperactivity, lower the quantity used and incrementally enhance the quantity primarily based in your tolerance. Alternatively, use 1 half Epsom salt to 2 components water for a foot tub. Soak your toes for about half-hour.
Toxicity knowledge exhibits MSM is extraordinarily secure and may be taken at excessive doses. As famous within the journal Vitamins, “As a Usually Acknowledged As Protected (GRAS) authorised substance, MSM is well-tolerated by most people at dosages of as much as 4 grams every day,”40 though toxicity research have reported no noticed opposed results as much as a degree of 5 grams per kilo per day.41
That mentioned, potential unwanted effects at greater doses embody intestinal discomfort, ankle swelling and pores and skin rashes. These are possible detoxifying results that may sometimes be mitigated or minimized by slicing again on the preliminary dosage and slowly working your method up.
