Safe to use old vitamins in my worm bin?

Posted by officedrone 6 (My Page) on

I tend to buy multivitamins in large containers and I always have some left over after the expiration date on the bottom. I'm wondering if I can pulverize them into tiny bits/powder and add to my worm bin? Seems like it wouldn't hurt them and would most likely provide some crop grit at least. Has anyone else done this?

Don't vitamins dissolve in water? I wouldn't count on it providing grit. In any case, most established worm bins have plenty of grit to go around.

I'm not sure what goes in multivitamin tablets. There's plenty of inert material in there besides the active ingredients. It probably won't do the worms any harm in the short term. I just don't know what happens in the long term as material builds up in the bin. It probably won't matter if you're talking about a dozen tablets once a year.
