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 health care professional.

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

This MSM powder is better that any one I have tried. Once you find the proper dosage for yourself, you do not feel the substance at all, you only experience its beneficial effect: it really works against inflammatory processes in your body, and it is stomach-friendly. Highly recommendable!

I prefer the capsules

Posted by currency on Sep 14, 2015

I've been using the capsule form and decided that taking 5-8 capsules a day wasn't the most convenient idea so I bought this. It quickly dissolved in a cup water with a little stirring. I took a sip and I just couldn't bear the taste. I thought I had high tolerance but this one is just too much for me. I love MSM and its benefits but i'll be sticking to capsules. I'm sure this would've been effective if I was able to ingest it so i'm still giving it 3-stars

Good MSM powder

Posted by 5233383557696211263 on Jun 17, 2015

This MSM powder has a very fine texture - it dissolves in water more easily than most MSM-powders I have used. Using it makes a great difference in the condition of my hair and nails: they shine.
