I want to invent a vitamin patch!

Can you take prenatal multivitamins as a regular daily vitamin if you're not pregnant? I am so depleted on vitamins and minerals, I'm thinking I need a boost.  As it is now, I double up once in awhile on my regular daily vitamin but I'm too afraid to do that more often because I don't want to OD on any one of the many vitamins in a multi-vitamin. 

I'm bad about remembering to take them regardless.  They need to make a patch for vitamins that you can wear and just absorb what you need for up to a week.  That'd be great!  There are patches for smoking and patches for birth control.  Why not a patch for vitamins?
