Does the methylsulfonylmethane in the Horbaach supplement containing a blend of hyaluronic acid and MSM do anything beneficial for vision, so as to be an asset in that choice of low-cost hyaluronic acid supplements?

This is actually the case. We cannot be leading and give you a detailed analysis of how this can play into treatment of eye disease or prevention, but it is safe to comment that MSM has anti-inflammatory and antioxidant activity. That would be of value in adding to the benefit of that nutraceutical in supporting vision well-being for both prevention and recovery of ongoing problems.
