MSM
Methylsulfonylmethane
MSM (Methylsulfonylmethane) is an organosulfur compound naturally found in green plants, animals, and humans. As a dietary supplement, MSM provides bioavailable sulfur for protein and connective tissue synthesis. Most clinically researched for joint pain (osteoarthritis), inflammation, and exercise recovery.
Divided doses or single dose with largest meal.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
MSM provides bioavailable sulfur with multiple effects:
Sulfur Substrate
Sulfur is required for synthesis of methionine, cysteine, glutathione, taurine, and many connective tissue components. MSM provides easily-absorbed sulfur.
Anti-Inflammatory
NF-κB pathway modulation reduces inflammatory cytokine production - mechanism for joint and muscle effects.
Collagen / GAG Synthesis
Sulfur is required for chondroitin sulfate and other GAG synthesis - supports cartilage matrix.
Exercise Recovery
Reduced post-exercise muscle damage markers and faster recovery in some trials.
Antioxidant Support
Glutathione and taurine synthesis depend on sulfur substrate.
What to expect
Days 1-14: minimal subjective change.
Weeks 4-12: peak joint and recovery benefit.
Long-term: sustained effect.
Evidence
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 1.5-3g daily; Oral capsule or powder; 1-3x daily. No checked live PubMed abstract verified this exact displayed dose, route, and frequency for the same molecule/formulation and relevant population.
Mechanism: MSM provides bioavailable sulfur with multiple effects: 1. Sulfur Substrate: Sulfur is required for synthesis of methionine, cysteine, glutathione, taurine, and many connective tissue components. MSM provides easily-absorbed sulfur. 2. Anti-Inflammatory: NF-κB pathway modulation reduces inflammatory cytokine production - mechanism for joint and muscle effects. 3. Collagen / GAG Synthesis: Sulfur is required for chondroitin sulfate and other GAG synthesis - supports cartilage matrix. 4. Exercise Recovery: Reduced post-exercise muscle damage markers and faster recovery in some trials. 5. Antioxidant Support: Glutathione and taurine synthesis depend on sulfur substrate.. No checked live PubMed abstract provided an exact-molecule/formulation sentence supporting this source-JSON mechanism claim.
Primary safety claim: No primary safety text present in source JSON. No checked live PubMed abstract directly verified this source-JSON safety claim at the displayed formulation, route, and regimen.
