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.

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?

Great value and quality. I've had 1 bottle already :) I don't think that this is a terrible tragedy that it contains (anti-caking agent) (in trace amounts)". Because of trace amounts.
