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 replenish the body's supply of sulfur.

Rated 5 out of 5 by from So far - so good This MSM mixes into liquids really great. To mask the bitter flavor - I would definitely recommend trying different fruit juices until you hit on one that works for you. (In our case, Mango did the trick.) Can not really comment on the effectiveness of this MSM for our particular health issues - as we understand that slow and steady will ultimately win the race.

Rated 5 out of 5 by from Source Natural MSM Is Awesome "I read an article while sitting in the doctor's office regarding MSM. I was so surprised about the benefits of this supplement. I started with the pills, but they did not seem as effective. Now I'm using the powder form and it is indeed-AWESOME. My skin looks wonderful, my hair and nails are VERY strong, thick, and my hair now has a wavy pattern (I'm African-American by the way) , and it eliminated my female problems during my monthly cycle! I WILL NEVER be without it! I do take about 7,800 mg which is 1/2 teaspoon X 3 daily along with Buffered C. Oh by the way, the article stated to use only Optimsm because this form is completely free of any contaminants. Simply amazing:)"

Rated 5 out of 5 by from all about optimsm when buying msm, only two things i look for........... make sure it is in powder form with no additives or preserving agents, and spot the logo saying it is made by OPTIMSM. this fits the bill winner

Rated 5 out of 5 by from Works Wonderfully I read a couple books on MSM and decided it needed to become a part of my life. This is my favorite MSM product because of the source, and because it mixes with water beautifully. There is no taste! I put a teaspoon in 2 cups of water. In fact, I put MSM in all my beverages. The pound container is far more economical for me than the capsules. My hair is so soft and my skin is radiant. Plus my body just feels better on MSM.

Rated 5 out of 5 by from Great Multi-purpose Product I bought this on sale a while back and am just now realizing how many wonderful uses it has. I purchased it for hair/skin/nails purposes but i find it lovely in the bath with dead sea salt. You get alot of product for the price sale or not and it will last you a good long time. I am very happy with it :)
