• Should caffeine be restricted during pregnancy? 

    Griebel, Craig; Javed, Mahwesh; Mugo, Leah; Venatta, Adree (Family Physicians Inquiries Network, 2012-04)
    Caffeine consumption <200 mg/d in pregnancy appears safe. (SOR: B, based on an RCT and cohort studies.) Older cohort studies suggest higher doses are associated with harmful effects.
