Abstract
Introduction: Methylsulfonylmethane (MSM) is a commonly used dietary supplement for the alleviation of joint and muscle pain. It is known primarily for its anti-inflammatory and antioxidant properties. While it is believed to have excellent bioavailability, little is known about its serum concentrations following chronic ingestion. Methods: 20 healthy men were supplemented with 3 grams of MSM daily for four weeks. Blood was collected at baseline and after two and four weeks of supplementation. Serum was analyzed for MSM concentration using Nuclear Magnetic Resonance (NMR) spectroscopy. Results: All baseline samples but one (0.028 mM) was below the limit of quantification for the NMR assay (0.002 mM). Serum MSM values increased across time (p<0.0001) to a mean (± SD) of 1.68 ± 0.60 mM at week 2 and 1.91 ± 0.81 mM at week 4. Values at week 2 and week 4 were greater than at baseline (p<0.05), but not different from one another (p>0.05). A total of 13 of the 20 men demonstrated higher serum MSM values at week 4 as compared to week 2. and eight of these men demonstrated an increase at week 4 of at least 25% above what was observed at week 2. Conclusions: Serum MSM concentrations increase following oral MSM supplementation, in somewhat of a timedependent manner in selected subjects. The pattern of increase varies somewhat from subject to subject, although all individuals experience an increase of approximately 1-3 mM after 2-4 weeks of supplementation.
