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.

iHerb Customer Reviews

Reliable product

Posted by iHerb Customer on Oct 06, 2017 | Verified Purchase

Very satisfied ! I've been using several product from the brand and they all work wonders for me. I used it as a general anti inflammatory but it also helps with hair loss, and to make it stronger. I also saw a different with my nails. Results are noticeable on the long term, don't expect to take it to see it works magic. I prefer powder to tabs because there is no ingredient added, that being said, it can be an inconvenience whent you travel. Better to avoid taking it on an empty stomach, it can cause discomfort.Finally, its gluten and dairy free! High quality, efficient and not too pricey, I recommend.
