Only B12 we use

Posted by Reviewer2392333 on Mar 18, 2010

I only use Natural Factors because it's clean and has no added sweeteners or fillers. I use this for myself and for my cats! I have used this product for a year and will not change. I love it.

Very good

I use this for my kitty who needs the extra B12. I am able to break the tablet into tiny pieces so that I don't offer kitty too much.
