Lignisul is just a brand name of MSM sold by Carrolwood. The word lignisul does not mean pure MSM. Lingni comes from LIGNIN which is the dissolved substance in the waste product of paper making. The MSM source for MSM supplements is often lignin from pine trees. Lignin is a molecule in plants that is part of a plant's cell wall. Lignin oxidation in oak wine barrels results in the vanilla flavors of wines. Lignisul MSM does not come from the United States.
