Absorption is a sodium-dependent active process (Ahearn and Murer, 1984; Florin et al., 1991; Langridge-Smith et al., 1983). When soluble sulfate salts (e.g., potassium sulfate or sodium sulfate) are consumed, more than 80 percent of oral sulfate doses are absorbed, as shown by isotopic tracer studies (Bauer, 1976; Florin et al., 1991).
