Product Overview

  • Dietary Supplement
  • (Methylsulfonylmethane)

MSM serves as an important source of bioavailable dietary sulfur, a mineral that plays a critical role in maintaining the integrity and elasticity of connective and other tissues. It is an important component of proteins found throughout the body, such as in hair, nails, skin and tendons. MSM is a naturally occurring form of organic sulfur found mainly in protein-rich foods such as eggs, fish and lean meat. Taking MSM each day helps to replenish the body's supply of sulfur.

MSM gives extra soft skin & thick, fast growin hair

Posted by Reviewer1313800 on May 07, 2007

Began taking MSM 1 yr. ago.Noticed that skin became MUCH softer.(I didn't even know then that MSM could have this effect.)Also, hair, which has always been very fine and thin became much thicker and grew much faster.(Also, at the time I didn't know MSM could have this effect.)I began taking MSM tablets but later added taking MSM in powder form.My skin became A LOT softer than it was when I just took the tablets.(I was taking it for pain.)I'm not sure if it helps the pain or not.I still have to take 6-8 200mg Ibuprofen tablets each day.(I have a very bad back injury from 30 yrs. ago.)I still take the MSM along with gelatin and gluscosamine.I haven't stopped taking them since I began 1 yr. ago.I don't know if I would notice a difference if I stopped.In the past sometimes I had very, very bad pain when I walked a lot.I've been walking an average of 1/2 hr. per day for the last 7.5 months.I didn't have unbearable pain during this time.(I usually walk for 3 hrs. at a time.)I recently began weight lifting for the 1st time.I avoided exercises I thought would hurt my back.2.5 weeks into it I got a very bad back strain with VERY bad pain.I take 2 teaspoons of powdered MSM in KoolAid which I drink all day long.I can't taste that amount.
