How much balancer should I give my horse?

As a horse owner, I'm often faced with the question of how much balancer to give my equine companion. Balancers are supplements designed to provide essential nutrients that may be lacking in a horse's regular diet. But with so many different brands and formulations available, it can be challenging to determine the right amount for my horse's specific needs. So, how much balancer should I give my horse? Is there a one-size-fits-all approach, or do I need to consider factors like age, weight, activity level, and existing health conditions? And how do I know if I'm giving too much or too little? I understand that it's important to consult with a veterinarian or equine nutritionist to get a personalized recommendation, but I'm curious to hear your thoughts on the general guidelines for determining the right amount of balancer for my horse.
