Silica Complete methylsulfonimethane

I have seen that in the ingredients of Silica Complete is methylsulfonimethane and I would like to know if it is derived from sulfamide because I am allergic.

R/ Is not the same. Sulfamide is an antibiotic and methylsulfonylmethane (MSM) is an organic sulfur compound also known as methylsulfone or dimethylsulfone. MSM is a chemical that is present in plants, animals and humans. It can also be made in the laboratory.
