Methylsulfonylmethane (MSM) is an organic sulfur compound that supplies sulfur for connective tissue and appears to lower inflammatory signaling and oxidative stress in joints. OptiMSM is a distilled, high-purity form used in most clinical-grade products.
Comfortable, mobile joints support the activity that protects healthspan. In a placebo-controlled pilot RCT, MSM significantly improved WOMAC pain and physical function in knee osteoarthritis, and a systematic review of joint supplements describes its anti-inflammatory, antioxidant mechanism. Human trials are still small and short, and the evidence is for symptom relief rather than longevity.
Peer-reviewed studies on the active compound — citations link to PubMed.
“Compared to placebo, MSM produced significant decreases in WOMAC pain and physical function impairment (P<0.05).”
“Of 20 supplements investigated in 69 studies, seven demonstrated large and clinically important effects for [osteoarthritis] pain reduction at short term.”
“This study indicated that MSM oral consumption improved both knee and systemic health conditions in healthy participants who experienced mild pain in the knee joint.”
“No supplements were identified with clinically important effects on pain reduction at long term.”
