i've been on a quest to create the perfectly balanced gel food for my goldies..but it seems no matter how much stuff i add, theres always too little of one thing or too much of another thing. i've noticed some recipes use dog vitamins, so i'm thinking of adding some powdered multi-vitamins to mine, hoping that'll help to make everything a bit more balanced. what kind of guidelines are there for adding vitamin supplements to gel food? should i use human, dog, or reptile vitamins?
