The "MESACA" study: methylsulfonylmethane and boswellic acids in the treatment of gonarthrosis.

RCTn = 60Joint Bone Health

RCT of 60 subjects with knee arthritis comparing 5 g of MSM and 7.2 mg of BA daily to placebo for 60 days. Pain was worse in the MSM and BA group at 2 months but not at 6 months. No significant differences in joint function were observed, but the need for anti-inflammatory drugs was significantly reduced in the experimental group.
