Sure. Omega-3, a critical ingredient for having smart kids, is depleted during pregnancy, and few women supplement enough to fully replenish.
Or, the idea that building a human depletes resources could be relatively uncontroversial, because duh.
However, a fixed cocktail of supplements isn't ideal. Some people actually get their bloodwork done and concentrate on what they really need.
How is what I'm saying "disgusting misinformation"? I'm very interested in what precisely you're angry at.
