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

Some people can take MSM with wonderful results and no side effects but I'm not one of those people. It gives me heart palpitations that become very uncomfortable and my blood pressure rises. I did notice that I had less back pain but that was hard to enjoy in light of the fact that my heart was jumping beats! I think that 1000 mg is pretty high for someone just starting to take it. I plan to buy it in powder form and take a very small amount and see if I can increase it slowly. I have heard that it is best to do it that way until your body gets used to it.

Bought this for the detox properties, but did not feel much of a difference even though I increased my dosage beyond the label recommendation. Would not re-purchase, as efficacy is disappointing. Will try the powder form next.

Been using for a month and a half and have felt very little improvement to my knees or lower back which usually hurts a little after a full day of walking (10k+ steps). Hair and nails have not grown thicker/stronger but my scalp has been flaking for a month now. Not sure if that is a side effect of this product or the other products. Taking this in combination with another multi-vitamin product for women. Will review again after I have finished the bottle. Taking 2000mg a day.

I think there might be too many additives in these tablets. I find they don't seem to absorb very well even though it is the opti-MSM. I'm switching back to Source Naturals when I finish this bottle.

I liked this, but I turned to Jarrows OptiMSM powder version, which has more value for your money.
