Overview
Jarrow Formulas' MSM capsules deliver 1000 mg of methylsulfonylmethane per serving in a 200-count veggie capsule bottle, marketed as a sulfur source to support and strengthen joints.
With up to 200 servings per bottle at a one-capsule dose, this is priced and sized for long-term daily use rather than a short trial. Beyond the MSM dose and capsule count, no further formula details are provided in this listing.

Who it's for
Suits people already taking a daily MSM supplement for joint support who want a long-running veggie capsule supply. Anyone looking for MSM combined with glucosamine or chondroitin should check other Jarrow formulas, since this is MSM alone.

Performance notes
MSM is an organic sulfur compound, and Jarrow's formula delivers 1000 mg per capsule in a vegetarian capsule shell, with up to 200 servings per bottle at a one-a-day dose. The listing doesn't specify additional ingredients, so this functions as a single-compound joint-support supplement rather than a combination formula.
