What is the best electrolyte in paste form? I was using the Apple a day which is a powder but the scoops are pretty big and he won't eat it. 

If you can order or find a store that carries the Forelyte paste by forefront equine it’s a super good one!

Electrolyte pastes are designed to be given before or after strenuous exercise?

I do both if it’s a super hot day and I’m anticipating a lot of sweat. Lol
