Nausea and vomiting of pregnancy (NVP) remains difficult to treat. Last century, thalidomide was used to alleviate NVP, but it caused teratogenesis by interfering with angiogenesis. The gasotransmitters hydrogen sulfide (H2S) and nitric oxide are mutually dependent on each other for their angiogenesis-related functions. Pregnancy-related requirements for increased endogenous H2S could create a temporary excess of sulfite, an H2S catabolite, which is toxic and can induce nausea. Sulfite oxidase, a molybdenum-containing enzyme, catalyzes oxidation of sulfite to sulfate, which can then be excreted or reused by the body. Supplementation with molybdenum should facilitate enhanced sulfite oxidase activity, thus lowering gestationally-elevated sulfite levels in the gastrointestinal tract and easing NVP.
