hi all. I was wondering if any of you tried Vita Pro B vitamin concentrate from first state vet? its supposed to be readily absorbed where other vitamins can just pass on through. I bought some and I'm trying it today. 1/4 tsp. for a gallon of water. its really concentrated and a little goes a long way. just wondering if any of you tried it and how did you like it? Thanks so much for reading. opinions welcome!
