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.

For best results, use with Jarrow Formulas JarroSil, the biologically Activated Silicon.

iHerb Customer Reviews

The cheapest & highest-quality Opti-MSM. 51% CHEAPER when compared to Sunfood's MSM power

Posted by iHerb Customer on March 16 2018 | Verified Purchase

Just awesome. The cheapest and highest-quality Opti-MSM I've ever found online. The "Sunfood, Pure Opti-MSM Flakes, 1 lb (454 g)" that I purchased & tried the first month seems to be of the exact same quality -- both in texture, color and taste -- but it's 51% more expensive. Why pay more for the same thing, right? :)

Product appears to be doing what it was advertized

Posted by iHerb Customer on November 30 2017 | Verified Purchase

We transitioned from a capsule product to Jarrow MSM powder. Directions were confusing as it says that one scoop is 1000mg. The volume however between the Jarrows and the GNC capsules is not comparable as it requires 10,000 mg of GNC capsules to equal 1 scoop of Jarrows which is 1,000mg according to the directions. Are we taking 10 times more than we should or was GNC shorting us by a factor of 10?

Thanks for your feedback!

Fantastic product!

Stomach pain

My wife and I both had to stop taking due to severe stomach pain within one week of taking MSM.
