One A Day vitamins shouldn't necessarily be taken only once per day, reports Laura Northrop at the Consumerist. You have to check the instructions first.

"One A Day is a well-known brand of vitamins, but its name is just that. A name. A brand. Not dosage instructions," she writes.

A reader noticed that the bottle of One A Day VitaCraves (for adults) gummies that he bought actually instruct you to take two each day.

There are 50 total gummies in a bottle, so it lasts for less than a month if used as instructed. He felt like he was completely misled.

Upon further investigation at our friendly neighborhood Duane Reade, we found that the One A Day VitaCraves kids' version also tells you to take two per day if the child is four or older.

However, all the One A Day tablets that we checked instruct the customer to take them only once per day, as the brand name would suggest.
