MSM (Methylsulfonylmethane): Organic Sulfur, Heavy Metal Chelation, and a Comparison with OSR/Emeramide

This week is a clinical reference from my ARP Practitioner Course.

Synthesized from the work of Dr. Sarah Myhill, Dr. Kathleen Janel & Natalie Earle FNTP.

1. What Is MSM?

Methylsulfonylmethane (MSM), also written as methylsulphonylmethane, is a naturally occurring organosulfur compound with the chemical formula C₂H₆O₂S. It is sometimes referred to as dimethyl sulfone, methyl sulfone, organic sulfur, or sulfonylbismethane.

It occurs naturally in small amounts in fruits, vegetables, grains, meat, eggs, milk, and even some beverages. Commercially, pharmaceutical- and food-grade MSM is most commonly derived from pine or birch tree bark through a distillation process. MSM is the oxidised metabolite of DMSO (dimethyl sulfoxide) and shares some of its therapeutic properties, though MSM is odourless and better tolerated.

Sulfur itself is the eighth most abundant element in the human body and is essential for the structural integrity of virtually every tissue. It is a component of two of the twenty standard amino acids (cysteine and methionine), and therefore integral to most proteins.

Key structural fact: MSM contains approximately 34% elemental sulfur by weight, making it one of the most concentrated bioavailable sulfur sources available.

2. Why Sulfur Matters: The Foundation (Dr. Sarah Myhill)

Dr. Sarah Myhill (MBBS, registered with the General Medical Council), author and integrative practitioner specialising in Chronic Fatigue Syndrome and mitochondrial medicine, has written extensively on the importance of sulfur as a ‘multitasking tool.’ Her work emphasises that widespread sulfur deficiency in Western populations drives a cascade of health problems that are frequently overlooked.

2.1 Why Most People Are Sulfur Deficient

Modern agricultural soils are chronically depleted of sulfur. Processing and cooking further reduce sulfur content in food. Additionally, glyphosate (the active ingredient in Roundup herbicide) directly interferes with sulfur metabolism and the gut microbiome’s ability to convert dietary sulfur into usable sulfate. The net result is systemic sulfur insufficiency even in people eating nutritious diets.

2.2 Dr. Myhill’s Summary of Sulfur’s Roles

Disulphide bonds are the ‘molecular glue’ that hold proteins together, skin, tendons, ligaments, gut lining integrity
Sulfur-containing amino acids (cysteine, methionine, taurine, homocysteine) are essential for enzyme systems, protein synthesis, free radical quenching, and liver phase II detoxification
L-cysteine and glutathione, the body’s master antioxidant, are both sulfur-dependent
Sulfur deficiency is associated with obesity, poor glucose control, atherosclerosis, and dementia
A sulfur-deficient gut compensates by proliferating sulfur-reducing bacteria, paradoxically causing bloating, diarrhoea, and intolerance to sulfur-rich foods (onions, garlic, brassicas, pulses)

2.3 Dr. Myhill on MSM for Heavy Metal Detoxification

Dr. Myhill states clearly: “I now know that MSM is a great way to pull out toxic metals.” She notes approximately 70 reported cases of participants moving from moderate or severe heavy metal toxification to negligible levels after 12-15 months of MSM alone, without any other chelation protocol. She describes this as a “safer, less intrusive, and less expensive” approach than conventional chelation. She recommends MSM as part of her ‘Full Monty’ detoxification overview, used alongside zinc, selenium, and sulfur-containing amino acids such as glutathione and methionine.

2.4 The Sulfur Deficiency-Gut Symptom Paradox

Dr. Myhill describes an important clinical paradox: sulfur deficiency presents with symptoms that mimic sulfur intolerance. When patients begin MSM, they may initially feel worse, increased gas, bloating, and discomfort. This is a die-off reaction as sulfur-reducing bacteria initially ferment harder before being crowded out. She advises starting at a very low dose and titrating upward slowly.

Clinical Note: Dr. Myhill recommends beginning MSM only after establishing a good nutritional base (her ‘Groundhog BASIC’ protocol), eliminating upper gut fermenters with Vitamin C (5 g/day) and Lugol’s iodine, and following a paleo-ketogenic diet to reduce fermentable substrates.

3. Dr. Kathleen Janel (“GI Janel”): High-Dose Sulfur Therapy

Dr. Kathleen Janel, ND (graduate of Bastyr Medical School, Biochemistry degree from University of British Columbia, over 25 years in clinical practice) specialises in complex gastrointestinal disorders including SIBO, SIFO, IBS, and gut-driven autoimmunity. She is known in functional medicine circles as ‘GI Janel’ and has developed a clinical protocol using high-dose MSM as a cornerstone intervention.

3.1 Dr. Janel’s Core Thesis

Dr. Janel observed that many patients with persistent SIBO are told to avoid sulfur-containing foods because sulfur-reducing bacteria (SRB) produce hydrogen sulfide (H₂S), an inflammatory gas when in excess. However, her clinical experience reveals the opposite approach works: by saturating the system with adequate sulfur (via MSM), the gut environment rebalances, SRB overgrowth is addressed at its root cause (sulfur deficiency), and bloating, loose stools, and constipation resolve. She describes this as ‘flipping the script’ on conventional SIBO management.

3.2 Conditions Dr. Janel Treats with High-Dose MSM

SIBO (Small Intestinal Bacterial Overgrowth): all subtypes
SIFO (Small Intestinal Fungal Overgrowth): Candida, Aspergillus
IBS-C and IBS-D
Leaky gut / intestinal permeability
Glyphosate toxicity and environmental sulfur disruption
Food sensitivities and histamine intolerance
Chronic fatigue and neurological symptoms driven by gut dysbiosis

3.3 Dr. Janel’s Product

Dr. Janel’s clinical formulation is called GI One Powder, a combination of MSM with marshmallow root, slippery elm, and acacia fibre. The MSM delivers the sulfur load while the botanical additions support mucosal healing and act as prebiotic substrates. She reports consistent patient feedback that this formulation ‘moved the needle’ where antibiotics and other SIBO protocols had failed.

3.4 Her Clinical Approach

Dr. Janel typically starts patients at a low dose and titrates upward over weeks to months, adjusting based on individual tolerance. In exceptional cases, patients with long-standing, treatment-refractory SIBO, she has supervised doses as high as 30 g/day for 8-week protocols with full symptom resolution reported. However, she is clear that this level is unusual and reserved for severe, carefully assessed cases.

4. Natalie Earle FNTP: Terrain, Mucosa & Glyphosate Disruption

Natalie Earle is a certified Functional Nutritional Therapy Practitioner (FNTP) and gut healing practitioner based in Jacksonville, Oregon, working under the umbrella of Nutrition With Confidence. She specialises in chronic fatigue, autoimmunity, PCOS, POTS/dysautonomia, and complex gut-immune dysfunction. Her personal healing journey included mercury poisoning and vaccine injury, which has deeply informed her clinical perspective on sulfur and detoxification.

4.1 Earle’s Framework: The Depleted Terrain

Earle’s central clinical argument is that today’s chronically ill patients are not simply ‘inflamed’, they are depleted faster than they can rebuild. The modern environment, dominated by glyphosate exposure, mineral-poor soils, processed food, and dysbiotic microbiomes, strips the body of bioavailable sulfur at a rate that food alone cannot replenish. She observes that even clients on nutrient-dense ancestral diets are failing to restore sulfur status without targeted supplementation.

4.2 Earle on the Mucosal Lining & MSM

Earle uses a compelling metaphor: the gut lining is a castle with a moat. The mucosal layer (produced by goblet cells as mucin) is that moat, the critical first line of defence. Goblet cells require sulfur to produce mucin. Without adequate sulfur, mucin production falters, the mucosal moat dries up, and the castle walls (epithelial tight junctions and villi) are exposed. The result is food sensitivities, histamine flares, constipation, brain fog, skin reactions, and post-exertional crashes.

She writes: “Most people are told this is ‘inflammation.’ But inflammation is often downstream of mucin depletion, sulfur deficiency, and microbial imbalance. MSM directly supplies safely tolerated sulfur, which your body uses to build glutathione (detox), synthesize collagen (repair), and give structure to the gut’s mucosal lining.”

4.3 Earle on Glyphosate and Sulfur

Earle highlights glyphosate as a key driver of the sulfur crisis. Glyphosate blocks an enzyme pathway (EPSP synthase) critical to beneficial bacteria, Bifidobacterium, Lactobacillus, and Faecalibacterium, while more resistant proteobacteria and sulfate-reducing bacteria fill the void. The result is a microbiome shifted toward H₂S overproduction, depleted sulfate availability, and systemic inflammation. She notes that research shows 100% of people in the United States have been exposed to glyphosate. MSM, by providing direct bioavailable sulfur, bypasses this enzymatic block and replenishes sulfate independently of the disrupted bacterial pathway.

4.4 Earle’s Key Areas MSM Supports

Mucosal lining integrity: goblet cell mucin production
Tight junction strength: leaky gut repair
Glutathione synthesis: master antioxidant and detox capacity
Collagen biosynthesis: joints, skin, hair, nails
Nervous system function, sulfur supports myelin and neurotransmitter metabolism
Microbiome rebalancing, restores sulfate availability, reducing SRB overgrowth
Histamine stability: supports DAO enzyme function via sulfur cofactors
Detoxification from glyphosate and environmental toxins

5. Benefits of MSM: A Comprehensive Overview

5.1 Anti-Inflammatory Action

MSM inhibits the NF-κB (nuclear factor kappa-beta) signalling pathway, a master regulator of inflammation. This reduces downstream production of pro-inflammatory cytokines including IL-1β, IL-6, IL-8, and TNF-α. It also attenuates activation of the NLRP3 inflammasome.

5.2 Antioxidant Support

MSM elevates intracellular glutathione levels. Animal studies show elevated liver glutathione following MSM supplementation, with partial protection against toxic liver injury. It also scavenges free radicals directly and supports the regeneration of vitamins C and E.

5.3 Joint, Connective Tissue & Musculoskeletal Health

Sulfur is integral to the formation and maintenance of cartilage, tendons, ligaments, and synovial fluid. Multiple randomized controlled trials demonstrate MSM’s efficacy in reducing pain, swelling, and functional impairment in osteoarthritis. MSM promotes osteoblast differentiation via the Jak2/STAT5b pathway and stimulates BMP-2 for bone formation.

5.4 Gut Lining and Mucosal Integrity

MSM supports tight junction proteins in the intestinal epithelium, reducing intestinal permeability. It promotes goblet cell mucin production, maintaining the protective mucosal layer. It shifts the gut microbiome away from sulfur-reducing bacteria overgrowth toward a more balanced anaerobic ecology.

5.5 Skin, Hair & Nails

RCTs have demonstrated improvements in facial wrinkle severity and depth, skin firmness, tone, texture, and hydration at doses of 1-3 g/day. Hair shine, volume, and appearance, and nail quality also improved significantly. These effects are attributed to sulfur’s role in keratin and collagen cross-linking.

5.6 Immune & Allergy Modulation

MSM has demonstrated efficacy in reducing symptoms of seasonal allergic rhinitis including sneezing, runny nose, and itching. It modulates both innate and adaptive immunity through its effect on NF-κB and oxidative stress pathways.

5.7 Cardiovascular & Metabolic Effects

A 2021 RCT found that 3 g/day of MSM over 16 weeks significantly raised HDL (‘good’) cholesterol in overweight and obese participants. Animal models of type 2 diabetes and obesity show improvements in insulin sensitivity, glucose metabolism, and body composition.

5.8 Cancer Research

In vitro and animal studies show MSM suppresses breast cancer cell proliferation by downregulating STAT3 and STAT5b pathways and reducing HER2 expression. It has also shown hepatoprotective effects and a tumor-delaying effect in colon and mammary cancer models. These findings are promising but not yet translated into clinical oncology protocols.

5.9 Neurological Function

MSM crosses the blood-brain barrier. NMR studies confirm detectable MSM in cerebrospinal fluid following oral dosing. This makes it relevant for neurological conditions driven by heavy metal accumulation, neuroinflammation, or mitochondrial dysfunction. Earle notes it supports myelin integrity and neurotransmitter cofactor production.

5.10 Exercise Recovery

MSM reduces post-exercise oxidative stress markers and muscle damage. Studies show reduced creatine kinase and malondialdehyde levels following eccentric exercise in supplemented individuals, indicating less oxidative damage to muscle tissue.

6. How MSM Chelates Heavy Metals: Mechanism

6.1 The Role of Sulfur in Metal Binding

Heavy metals including mercury, lead, arsenic, cadmium, and aluminium are strongly electrophilic, they have a strong affinity for electron-rich atoms. Sulfur, with its valence electrons and electronegativity, is one of the most potent electron donors in biological chemistry. The sulphydryl (-SH) group found in cysteine, glutathione, metallothionein, and related compounds is the primary biological anchor for toxic metal sequestration.

MSM functions in metal chelation through several interconnected mechanisms:

Mechanism 1: Direct Sulfur Donation

MSM provides bioavailable sulfur that the body metabolises into functional -SH groups via the transsulphuration pathway. This directly increases the pool of free cysteine and glutathione available to bind and sequester heavy metals. Once a metal is bound to glutathione, the complex is conjugated by glutathione-S-transferase and eliminated via bile or urine.

Mechanism 2: Upregulation of Endogenous Chelators

By replenishing sulfur, MSM increases the body’s production of its natural chelating molecules: glutathione (GSH), metallothionein, and cysteine. Glutathione is the primary intracellular chelator. Metallothionein is a cysteine-rich protein that sequesters cadmium, zinc, copper, and mercury with remarkable affinity. Both require sulfur as their active chelating atom.

Mechanism 3: Improved Cell Membrane Permeability

MSM alters the fluidity and permeability of cellular membranes. This facilitates the movement of toxins out of cells and into circulation where they can be bound by chelating molecules and excreted. This cellular detoxification is distinct from the metal-binding mechanism and enhances overall toxin clearance.

Mechanism 4: Liver Phase II Detoxification Support

Sulfur is a critical cofactor for Phase II liver detoxification, specifically the sulphation conjugation pathway. By supplying sulfur substrate, MSM enhances the liver’s capacity to conjugate and neutralise both heavy metals and organic toxins including glyphosate, pesticides, and environmental chemicals, facilitating their excretion via bile and urine.

Mechanism 5: Antioxidant Protection During Detox

Heavy metal mobilisation generates oxidative stress. MSM’s role in elevating glutathione and directly scavenging hydroxyl radicals helps protect tissues from the oxidative burden of chelation. This makes MSM gentler than pharmaceutical chelators that can mobilise metals without providing antioxidant protection.

Metals for which MSM-mediated chelation has been specifically noted: Mercury, lead, arsenic, aluminium, cadmium, and nickel.

7. Dosing Recommendations

7.1 General Health & Maintenance

The following doses represent a synthesis across the three practitioners referenced:

Minimum daily requirement (dietary sulfur): 800–1,500 mg/day — Dr. Myhill (body does not store sulfur; daily replenishment needed)
General health maintenance: 1–3 g/day — Standard supplementation range; GRAS FDA threshold ~4.8 g/day
Gut health, leaky gut, microbiome support: 3–10 g/day — Dr. Janel & Natalie Earle; begin low, titrate slowly
Therapeutic / chronic conditions: 3–10 g/day — Dr. Myhill: aim for 3 tsp (10 g) over 3 months; split dosing preferred
Heavy metal chelation — moderate load: 10 g/day — Dr. Myhill recommendation; minimum 6 months
Heavy metal chelation — high load / refractory: 10–30 g/day — Dr. Janel; exceptional cases only; titrate over weeks; monitor closely

7.2 Practical Dosing Protocol (Dr. Myhill)

Start: 1/4 teaspoon (~1 g) per day in water
Titrate: increase slowly over days to weeks according to tolerance
Target for gut/detox work: 3 teaspoons (~10 g) per day
Duration for heavy metal clearance: minimum 6 months; full benefit at 12-15 months
Safety ceiling: up to 8 g per kg body weight per day (theoretical maximum), a 70 kg person could theoretically take 560 g/day safely

Important: do NOT take mineral supplements within 3 hours of therapeutic chelation doses (minerals may compete for binding).

7.3 Signs of Starting Too Fast

Increased bloating and flatulence, likely die-off of sulfur-reducing bacteria
Headache, brain fog, or fatigue, detox burden exceeding clearance capacity
Skin flares: toxin mobilisation
Palpitations or loose stools

If these occur: reduce dose by 50% and hold for 1 week before titrating again. These symptoms indicate the protocol is working but is proceeding too quickly.

7.4 Quality Considerations

Use only distilled or crystalline MSM (at least 99.9% purity)
Avoid petroleum-derived MSM: choose pine or birch tree-derived sources
OptiMSM (Bergstrom Nutrition) is the most studied commercial brand
Powder form is preferred for high-dose protocols due to cost-efficiency
Dissolve in warm water; can be added to juice

8. Comparison: MSM vs. OSR/Emeramide vs. DMSA

8.1 Overview of OSR / Emeramide (NBMI)

OSR#1® (Oxidative Stress Relief), now known as Emeramide or NBMI (N,N’-bis(2-mercaptoethyl)isophthalamide), is a synthetic lipophilic chelator developed by Dr. Boyd Haley and commercialized by EmeraMed Ltd. It is structurally built from two natural components: carboxyl benzoate (found in cranberries) and cysteamine (found naturally in meat and as a terminal component of Co-enzyme A).

The molecule features two flexible sulphydryl (-SH) arms that can rotate freely to grasp heavy metal atoms, particularly mercury, from multiple angles. Emeramide is lipophilic, allowing it to cross the blood-brain barrier and reach metals sequestered in CNS tissue, a significant advantage over hydrophilic chelators like DMSA.

Once bound, the Emeramide-metal complex is chemically inert, biologically stable, and excreted through the P-450 detox pathway into the bowel. The bond is so stable it requires 230°C to break. Approximately 2.5 million doses of the original OSR#1® formulation were sold as a supplement with no significant adverse reactions reported. Phase 1 and Phase 2 clinical trials confirm safety at 300 mg/day for 30 days and 600 mg/day for 10 days without adverse events or depletion of essential minerals. In the USA, Emeramide is available as an Investigative New Drug (IND) under IRB supervision, or via right-to-try. It is available in various countries through EmeraMed’s early access program.

8.2 Comparison Summary

MSM (Methylsulfonylmethane): Natural organosulfur supplement; derived from pine/birch trees; crosses blood-brain barrier; sulfur donation supporting glutathione and cysteine; gentle/indirect chelation strength; very low redistribution risk; GRAS dietary supplement; freely available OTC; excellent safety profile (LD50 >17.5 g/kg); 10 g/day (Dr Myhill) up to 30 g/day in severe cases (Dr Janel); months to clear; gut-friendly, supporting mucosa and microbiome; very inexpensive; best used for general health, sulfur repletion, gentle ongoing detox, gut repair, and prevention.

OSR/Emeramide (NBMI): Synthetic lipophilic chelator from benzoate and cysteamine; crosses the blood-brain barrier; dual -SH arms bind metals irreversibly, scavenges hydroxyl radicals, prevents Fenton reaction; targets mercury primarily plus lead, arsenic, iron, cadmium; strong, direct, irreversible binding; very low redistribution risk; Investigational New Drug in USA, available in some countries; excellent trial safety (no adverse events at 300 mg/day for 30 days); 100–300 mg/day typical, higher under supervision; weeks to months timeline; neutral for the gut; moderate to high cost; best used for targeted mercury/heavy metal chelation, especially with neurological involvement.

DMSA (Pharmaceutical, hydrophilic): Synthetic meso-dimercaptosuccinic acid; does not cross the blood-brain barrier (limited CNS access); binds metals via -SH groups and promotes renal excretion; strong, direct, reversible binding; moderate redistribution risk if underdosed or mistimed; FDA-approved drug (Rx required); generally safe but can deplete essential minerals and cause GI side effects; 15 mg/kg once weekly (Dr Myhill protocol); weeks to months; can cause GI upset, nausea, and diarrhoea; moderate cost; best used for acute/moderate-severe poisoning under medical supervision.

8.3 Clinical Decision Framework

The choice between MSM, Emeramide, and DMSA is not binary, they can be used in a staged or combined approach:

Stage 1, Terrain Preparation: MSM at maintenance to therapeutic doses to replenish sulfur stores, support glutathione production, heal the gut, and begin gentle background chelation. This is appropriate for all patients regardless of metal load and should be started months before aggressive chelation.

Stage 2, Targeted Chelation: For confirmed moderate-to-heavy metal burden, especially mercury with neurological involvement, Emeramide offers superior targeted action with better CNS penetration and an excellent safety profile. DMSA remains the conventional pharmaceutical option for confirmed acute/sub-acute poisoning under medical supervision.

Stage 3, Consolidation & Maintenance: Return to MSM maintenance doses long-term alongside a clean diet and regular Epsom salt baths (transdermal sulfate) to prevent re-accumulation.

Note: OSR/Emeramide is not currently licensed as a medicine in the UK or USA. Always advise students to check current regulatory status in their jurisdiction before recommending investigational agents. DMSA requires a prescription and medical supervision.

9. Safety Profile & Contraindications

9.1 Safety

MSM has an excellent safety record across decades of human use. The FDA has granted GRAS (Generally Recognised As Safe) status to OptiMSM at doses under 4,845.6 mg/day. The LD50 in animal studies is greater than 17.5 g/kg body weight, making it as safe as water by comparison. Dr. Myhill notes it can theoretically be taken at up to 8 g/kg body weight per day. No serious adverse events have been reported at standard doses. At very high doses, transient gastrointestinal symptoms (bloating, loose stools, nausea) may occur, typically reflecting the microbiome adjustment discussed above rather than direct toxicity.

9.2 Practical Precautions

Blood thinning: MSM may have mild anticoagulant effects; use caution with patients on warfarin or similar medications
Allergy: rare; usually to sulphites rather than organic sulfur compounds
MTHFR and transsulphuration variants: patients with CBS (cystathionine beta-synthase) upregulation may initially struggle with sulfur supplementation; introduce very slowly
Pregnancy: insufficient safety data in pregnancy; caution advised
SIBO/high H₂S: counter-intuitively, Dr. Janel argues MSM is beneficial, but start extremely low (1/4 tsp/day) and titrate very slowly

9.3 Drug Interactions

No significant drug interactions are established. MSM may enhance the effectiveness of anti-inflammatory medications and potentially reduce their required dose. It may also enhance the effect of blood thinners; monitor INR in anticoagulated patients.

10. Summary and Key Teaching Points

What is MSM? A naturally occurring organosulphur compound providing 34% elemental sulfur. GRAS status. Derived from pine/birch or found in foods.

Why does it matter? Sulfur deficiency is widespread due to soil depletion and glyphosate interference. It underpins leaky gut, poor detox capacity, inflammation, joint disease, and heavy metal accumulation.

Key clinicians: Dr. Sarah Myhill (UK, gut, detox, heavy metals), Dr. Kathleen Janel (USA, SIBO, IBS, high-dose therapy), Natalie Earle FNTP (USA, terrain, mucosa, glyphosate, autoimmunity).

General health dose: 1-3 g/day maintenance; 3-10 g/day therapeutic. Chelation dose: 10 g/day (Dr. Myhill); up to 30 g/day in extreme cases (Dr. Janel). Always titrate from low. Duration: 6-15 months minimum.

Mechanism of chelation: Sulfur donation → glutathione/metallothionein upregulation; improved membrane permeability; Phase II liver sulphation support; antioxidant protection during mobilisation.

Vs. OSR/Emeramide: MSM is indirect, gentle, foundational, and freely available. Emeramide is a direct, targeted, lipophilic chelator that crosses the BBB, ideal for CNS mercury burden. They are complementary, not competitive.

Always start low and titrate: Herxheimer-type reactions are common, especially in sulfur-deficient patients with dysbiotic gut flora.
