MSM (Methylsulfonylmethane) is an organic sulfur compound naturally found in small amounts in foods like cruciferous vegetables, onions, and garlic. Sulfur is the third most abundant mineral in the body and is a critical building block for keratin (the structural protein of hair and nails), collagen cross-linking (the disulfide bonds that give collagen its strength), glutathione synthesis (the body's master antioxidant), and chondroitin sulfate (the primary component of joint cartilage). Modern diets are often sulfur-deficient due to food processing and soil depletion.
The sulfur connection: Sulfur forms disulfide bonds — the chemical bridges that give keratin its rigidity (strong hair, hard nails) and collagen its tensile strength. Without adequate sulfur, your body can produce collagen but it will be structurally weak. MSM provides a bioavailable sulfur pool for all these processes.

|---|---|
| Product | Lake Avenue OptiMSM Flakes (992 g) |
| Dose | 3 g/day powder mixed with breakfast |
| Timing | With breakfast (food reduces potential GI sensitivity) |
| Rationale | 3 g is the evidence-based dose for joint, hair, and anti-inflammatory benefits. OptiMSM is the distillation-purified form (vs crystallization) with highest purity. |
| Duration | 4-6 weeks for joint/inflammation benefits; 3-6 months for visible hair/nail improvements |

A 2025 study in Nutrients was the first to demonstrate significant post-exercise immune effects with lower MSM doses (0.5–1.0 g/day), compared to previous work requiring 3 g/day. Healthy experienced runners supplemented with MSM (1.0 g/day) for 30 days prior to a 21.1 km running event showed modulated immune response-related mRNA expression, including improved markers of oxidative stress and inflammation. The study reinforces MSM's role as an exercise recovery supplement at more practical dosages. MSM maintains its GRAS (Generally Recognized As Safe) status with well-tolerated doses up to 4 g daily, with only mild gastrointestinal side effects reported most commonly.
