Basically all pet foods need added vitamins since the food ingredients alone can not meet even the minimum requirements. Further, considerable amounts of vitamins are lost due to manufacturing and environmental conditions. So, the question is what vitamins, how much of those vitamins, and whether the vitamins actually have their efficacy intact until eaten by your pets. Microencapsulation is the best technology available to protect the vitamins from breaking down before reaching the pets' tummy. Currently,Science4Pets is the only one that offers microencapsulated and non-China multivitamin supplements for dogs and cats intended for raw and home cooked foods as well as well as those needing supplementation to mediocre dry kibbles or other pet foods bought from the store.
