I've been told that banana splits and root beer floats are both excellent sources of vitamin i.
Most drug stores I visit don't carry those things, but some might sell cartons of vitamin i in its pure form in one-pint containers. Breyers sells a high-quality product, I'm told.
I'm also interested in the best delivery method. Taking it by mouth seems simplest, but I know many babies seem to enjoy administering it transdermally.
My health is important to me so I've come to the Internet for advice about this.
