Bests & Worsts Reviews from Amazon

Quality seemed and looked good until I tried this. Other MSM supplements I've ingested worked right away and I immediately felt and noticed a difference within a few days. With this - nothing so far. I would have continued to use this longer to see if benefits finally manifest, but I realized this product's sourcing is unclear. I truly thought the product was sourced from Canada, but the company's partners are in Canada. The fact that they cannot clearly state where the crystals actually come from, ain't cool to me as a consumer. If you don't care about this, and this ends up working for you, this review doesn't matter but for me, everything's gotta line up even if it means I'll pay more. Btw, the press and seal feature of this "resealable" pouch is bogus. From first use, it opened with it fully sealed and stuck on one side only.
