This product is good because contains OptiMSM which is bioavailable sulfur with pharmaceutical quality >99%. I like also the 200g bottle. But I don't like the fact Jarrow company uses anti caking agent - silicon dioxide... SiO2 or Silicon dioxide is an additive they put into various foods to prevent clumping or caking. These are not a problem for customers but purity is... so I give 4 stars.
