Fiber to keep the digestive from blocking.
Tons of water is necessary anyway, but especially with the fiber intake. Without water, fiber will create a brick inside the digestive tract.
Ingesting coconut oil to line the walls of the digestive. It acts as a lubricant to help everything flow.
Magnesium also aids the digestive plus helps with agitation levels.
And just to reiterate... LOTS of water!
