Do Balance protein powders contain sulphites?

Sulphites are compounds that contain a sulphite ion.  They are present naturally in foods, or can be added as a preservative to food to enhance colour, prolong shelf life and to prevent bacterial growth.  Sulphites are safe to eat for the majority of the population, however some individuals may experience a sensitivity to sulphites. 

Sulphites are not used or added in the processing of our protein powders, however some amino acids naturally contain sulphur in their chemical structure e.g. methionine.
