Overview

Now MSM delivers 1000 mg of methylsulfonylmethane per vegetarian capsule, in a 400 count bottle that's kosher, non-GMO and unflavored, made in the USA.

With 400 capsules in one bottle, this is a bulk option for buyers who already take MSM regularly rather than a trial size. The vegetarian capsule shell and kosher certification widen who can take it compared to gelatin based versions.
