Homemade Cat Food

I bought this B Complex to use to make homemade cat food and I wanted to make sure my cat receives a complete diet. After doing a little research, and looking up each ingredient, I was looking for the benefits of a high quality vitamin and I was able to find this jar. It actually offers more varieties of Vitamin B than other versions. Most weren't actually a complete B Complex, this was my concern while shopping around. So far, so good!

Recommended for Inflammation

We started giving our dog this supplement on the recommendation of our vet. As our dog recovers from IVDD surgery, it has helped tremendously to manage inflammation and promote general wellness/health. My only complaint is that the bottle seems oversized for what you get, which makes me feel like I'm getting less than what I paid for (which may not be the case!). It would be better in a smaller bottle that was filled more, or just with more in it.

High quality

I’m glad this brand offers supplements like this for dogs with organic, high-quality ingredients. It’s not easy to find products like this, and I appreciate the thoughtful formulation and clean sourcing. I feel good about including this in my pet’s routine and will continue buying from this line.

Easy Way to Support My Pet’s Energy and Overall Health

I’ve been using Dr. Mercola Organic Vitamin B Complex for Cats & Dogs, and I’m very happy with the results. I like that it’s made with organic ingredients and specifically formulated for pets, which gives me confidence in the quality and safety of the supplement. The powder is easy to mix into food, and my pets didn’t seem to notice any change in taste, which is always a big plus. Since starting this vitamin B complex, I’ve noticed improved energy levels and a healthier-looking coat, especially in my older pet. It also seems to support overall wellness and appetite. Overall, this supplement has been a great addition to my pets’ routine. It’s convenient to use, gentle on their system, and provides important B vitamins that support daily health for both cats and dogs.

bottle is barely half way filled, why such a large bottle

I don't know if it helped much with my 4 cats I mixed into wet food. my big boy ran away been gone a while,. The bottle is expensive and it's less than half full. why use such a large container for so little product ? don't think I'll buy this again , gonna try healthier food brands
