Flintstones chewables, or Gummi's.
Dead serious. Adult vitamins give me headaches, and prenatal vitamins make me violently ill. The kids ones, otoh, are yummy in my tummy :)
Between 70% and 95% of each vitamin ends up in the toilet, having never been absorbed in the first place. WAY BETTER THAN NOTHING, but you really don't have to stress about them too much, because they're mostly peed away.
