Not required. Not banned. Optional. Off the main protocol.
We are downgrading MSM (methylsulfonylmethane, often sold as “MSM sulfur”) off the core Copper Revolution protocol. It is not moving to an avoid list. Some people still benefit from it. Many people do fine without it — and some feel better when they stop.
This update comes from reviewing Stanley Jacob’s MSM/DMSO claims, the chemistry of what MSM actually is, clinical patterns we see in our group, and our own long-term use.
Short version
Copper, boron, iodine, zinc, selenium, magnesium, potassium balance, and food basics remain the core.
MSM is optional — useful for some joint responders, unnecessary for many, and a common contributor to bloating at teaspoon doses.
If you use MSM, keep it last in the staging order (after allergies calm), at the lowest dose that helps, and pause it if the belly bloats.
Why we revisited it
MSM got popular through Stanley Jacob’s DMSO/MSM clinic work and books (The Miracle of MSM, MSM: The Definitive Guide). The marketing pitch is big: joints, headaches, allergies, detox, sulfur donation, membrane “detox,” stroke lore, methylation, metallothioneins, and more.
Copper Revolution already covers a lot of what people chase with MSM — especially headaches and joint problems — through copper and boron (and the rest of the mineral sequence). So the fair question was:
Does MSM add enough unique value to stay on the core stack — or is it optional?
What holds up
- Mild anti-inflammatory / antioxidant effects
This is the most believable MSM story. Modern work points more to dampening inflammatory signaling and oxidative stress than to “rebuilding your cartilage because you were sulfur-deficient.” That also fits the timing: people often notice joint comfort changes faster than true structural rebuild would take.
- Some people feel more joint pain when they stop
We have seen this, including in our own household. That is real n=1 data. It does not prove MSM is required for healing. It does prove MSM can still be a useful adjunct for some joint responders.
- Adaptation flares are real
People often have to ease into MSM. Early allergies, fog, or “stirring” symptoms show up — similar to how copper can feel activating early while detox and antihistamine systems wake up. That is why we already said: sulfur last, after copper/zinc/selenium work and after allergies settle.
Anti-inflammatory long-term and “noisy” short-term are not a contradiction. Dose, terrain, and sequence matter.
What does not hold up well enough for “core protocol” status:
Sulfur donor miracle?
MSM is marketed as organic sulfur (~34% S). Fair enough chemically. But if you eat enough protein, you already get sulfur amino acids (methionine/cysteine) — the body’s normal sulfur bricks for glutathione, disulfides, and connective tissue chemistry. MSM is not a mandatory sulfur donor on top of that.
Also, a lot of oral MSM is absorbed and then largely excreted. It is not aggressively “metabolized into your collagen.”
Mercury detox / redistribution hero?
Mercury loves thiols (-SH): cysteine, glutathione, NAC, ALA, pharmaceutical chelators. MSM is a sulfone (dimethyl sulfone) — oxidized sulfur, no free -SH. Conflating “sulfur” with “MSM chelates/redistributes mercury” is a category error.
People often tolerate MSM better after mercury work. That can mean the terrain is calmer — not proof MSM was the mercury shuttle.
Electrolyte?
No. Electrolytes are ions (sodium, potassium, etc.). MSM is a neutral polar molecule. It does not act like salt.
“Reverses membrane polarity so cells detox”
This is Jacob-era clinic poetry more than clean biophysics. Selective permeability is healthy. Nonspecific leakiness is not automatically a virtue. Detox is mostly liver enzymes, transporters, bile, urine — not flipping membrane charge.
Stroke healing?
The serious experimental story is mostly DMSO, not oral MSM. DMSO has multi-hit acute CNS pharmacology (edema, radicals, platelets, inflammation, etc.). MSM is the milder cousin. Do not import DMSO stroke lore onto daily MSM powder and call it protocol law.
Metallothioneins?
Metallothioneins are cysteine-rich proteins turned on mainly by zinc/stress (MTF-1), built with cysteine. MSM is at best a weak, indirect maybe-if-sulfur-amino-acids-are-limiting story — not a reason MSM belongs in the core stack.
Primary methyl donor?
The real methyl economy runs through SAM, fed by methionine via folate/B12 or betaine pathways. MSM is not a substitute for methylfolate, B12, or betaine. There is a thin lab hint that some MSM methyl carbons can show up in DNA methylation in cells; that is not “MSM fixes methylation / replaces methylfolate.”
Copper and iodine help the machine around methylation (energy, enzymes, thyroid, etc.). They are not SAM lookalikes either — and they still do not make MSM mandatory.
Copper depletion scare?
High sulfur can antagonize copper in livestock (especially with molybdenum). That does not cleanly prove teaspoon MSM depletes copper in humans. Still, multi-gram daily sulfur for years is an extra variable you do not need if copper is the point of the protocol.
Oxygenator?
No. MSM mostly passes through the body unmetabolized. It’s not a element, it’s a molecule. Very little is broken down.
Bloating: the practical reason many should pause it
MSM commonly causes GI effects: bloating, gas, loose stools — especially at teaspoon-class doses (~3–4+ grams).
The likely mechanism is boring and local: osmotic water pull in the gut and/or gas from sulfur traffic / microbiome shift — not “enhanced sodium detox.”
We already wrote about bloating on copper (sodium/potassium, die-off, constipation, vitamin C, etc.). MSM belongs on that checklist too. If you are bloated on the protocol and taking MSM, pause MSM for 1–2 weeks while keeping the rest steady. If the belly calms, you MSM may well be rightly blamed.
Absence of giant MSM trials does not automatically mean “suppressed miracle.” MSM already has industry support and short human joint studies. What it lacks is a unique, mandatory mechanism that copper + diet + the rest of the protocol do not already cover for most people.
How to use MSM now (if you use it)
Optional. Skip it unless you have a reason (especially joint comfort that clearly returns when you reintroduce it).
Last in line. After copper/zinc/selenium foundations and after major allergy reactivity settles.
Lowest effective dose. Many people do not need a full teaspoon. Try ¼–½ teaspoon, or pulse on flare weeks.
Pause for bloating. If bloating is a complaint, MSM is a prime suspect.
Not on the avoid list. Quality MSM is fine for people who tolerate it and notice a benefit, especially as an anti inflammatory, for headaches, or for jointpain. But the rest of the Copper Protocol has those areas well covered.
Overall, upon review, MSM Sulfur just does not hold up well enough to fit the pattern of a “miracle mineral”, and thus, we are removing it from the protocol. It’s also costly.
Bottom line
We are not anti-MSM. We are anti-mandatory MSM.
Copper Revolution’s center of gravity is copper and the mineral sequence that makes copper work. It does not need to sit in the middle of the protocol for everyone — especially when a teaspoon a day may be quietly causing the bloating some of you have been reporting.
Sometimes, we heal by stopping taking things that prove up to be counterproductive.
