It is safe but, in my opinion, it is not necessary with commercial food and not a good choice for homecooked because there aren't enough vitamins/minerals in it. So, for most dogs it is just another thing to spend money on...
If you use it for homecooking, you will have to use other vitamins/minerals also.
