Lignisul MSM (methyl-sulfonyl-methane), a natural sulfur compound used as a nutritional supplement for a variety of ailments, including muscle and joint pain, has become the first MSM product to receive GRAS (Generally Recognised as Safe) status under the US Food and Drug Administration requirements for GRAS self affirmation, according to its supplier, CarolwoodMSM.

A GRAS report was initially commissioned by Carolwood to support the safe use of Lignisul MSM in foods.  The report was reviewed by a panel of food safety experts who concurred with Carolwood's determination that Lignisul MSM meets the requirements for GRAS status. In making its GRAS determination, the panel reviewed previously published reports of the human consumption of MSM, reports on the purification and processing of other food ingredients containing sulfur, and a large body of published literature covering the safety and technical effects of MSM in food.

"Lignisul MSM is the only brand of MSM that has undergone third-party testing, as well as safety and clinical research trials," said John Turner, vice president of sales for CarolwoodMSM.
