Jarrow Formulas MSM Sulfur is an organic source of bioavailable sulfur. Sulfur is an antioxidant mineral found in major structural tissues of the body such as cartilage. The sulfur from MSM is used to produce glycosaminoglycans (or mucopolysaccharides) present in proteoglycans such as chondroitin sulfate, dermatan sulfate, and hyaluronic acid. These sulfur containing glycosaminoglycans are found in high concentrations in connective tissues, including joint cartilage, skin and collagen.

Suggested Use

Take 1 scoop per day or as directed by your qualified healthcare professional.

iHerb Customer Reviews

Product is quality

Posted by lifeworthchanging on Oct 21, 2016

Good product and can't say I'm sold on MSM doing any good for me personally. Probably won't by this again but nothing against Jarrow, I use a few of their other products and really like them.

It works wonders for me

Posted by 4724775230166134450 on Oct 17, 2016

I have a problem with my knee: as soon as I start regular training, my right knee starts giving me problems. I work out with weights and making squats or leg press was really painful. Running on the treadmill was another exercise I avoided at all, because it hurt too much. I tried many supplements with Chondroitin and Glucosamine and they helped a little bit, but not that much. Since I use this MSM I don't have any more pain. It is almost unbelievable for me, I think anyone who has had a problem for long time and then suddenly find a medication that really works can relate to what I say. Now I can do squats and I can run and everything is fine, my knee is really OK. I use 3 g per day, mixed with water or directly in milk / yogurt... The taste is not good, but who cares? I wish I had discovered it earlier!

Good Product

This is much better product compared to an earlier one I tried. Would be even better if Jarrow has Pure crystal flakes ones too.

This product doesn't come with a scoop!!!

Posted by 4909601168547320220 on Apr 12, 2016

I was extremely frustrated when I didn't find any scoop in this powder. How am I supposed to take one scoop per day? What kind of measurement is it?
