From a habit-forming perspective, my household has had a lot of success with gummy multi-vitamins, because they're fun and tasty to take.

In the US, drug stores always seem to have a selection of these.

Id recommend one with vitamin B-12 or B complex.

I take winegums, which are chewy sweets with zero vitamins in, but plenty of sugar. Highly recommend it.
