DMS rises as a gas into the upper atmosphere where it's oxidized into DMSO and MSM in the presence of ozone and ultraviolet light. These two compounds dissolve in atmosphere moisture and return to the earth in rain or snow. DMSO and MSM then enter the roots of plants through the soil. In the plant, sulfur and other minerals are bound to carbon and further covered into an absorbable form for humans. It's also found in horsetail herb, spearmint,tea and coffee.
