                                The Food and Drug Administration (FDA) has classified sodium sulfate as Generally Recognized As Safe (GRAS) for certain indirect food additive uses. The question of whether sodium sulfate is safe for humans, however, is not a simple yes or no answer and depends entirely on the context and quantity of exposure.
