I have used MSM for years for specific areas, so it is easy to forget that all qualities are not the same. I ran across another brand of MSM & since the label had a dr's name attached & it was a significant amount cheaper I bought it. BAD IDEA!!! I ended up taking twice the amount of what I do the Nature's Way product without getting any of the results. Nature's Way product is a good quality at a reaonable price &iHerb aways gives excellent service. Be assured this is a lesson I won't haveta learn again. I don't use price to guage what quality of gas I put in my vehicle so it doesn't make sense to use it for what goes in my body...Deb in Bama

This is powerful stuff and I had a reaction of feeling achy, some trouble breathing, and altered mood. This may have been a detox reaction, but even occured when I would break open a capsule and use a little of it in water. I can handle detoxing effects, but what I cannot handle is how is made me short tempered, moody, and irritable-depressed really. I don't ever feel like this, so I tried it a couple of times to be sure it was the product and the same thing happened. I did not feel like something positive was happening to me so I will no longer use this product. I take another msm brand with no fillers or binders, pure msm, but not opti-msm and have nothing but beneficial results from that one.

I just couldnt function on these. Everyone says they give you energy and I just had the opposite effect of fatigue, unfortunately they were of no benefit at all.

Wish they were capsules instead of tablets. Hard to swallow
