Coconut oil alone will make you poop. And it's no surprise that coffee can make you poop too. So, when you add the two together, you become "unstoppable".
The main component in coffee that causes the urge is caffeine while it is MCTs (medium-chain triglycerides) in coconut oil that stimulate bowel movement.
Now you know how "dangerous" these duo are when you put them together. They don't just create bulletproof effect that peps you up. They make you poop like never before.
I'd suggest that you add no more than two teaspoons of coconut oil to your coffee. Just to make sure you don't "explode" in the wrong place at the wrong time.
But if you're severely constipated, you might want to up your coconut oil intake to help relieve constipation.
