It is the curcumin in turmeric that is not very well absorbed into the bloodstream. Therefore, adding a little black pepper to anything with turmeric will greatly assist its absorption into your body so you can enjoy the benefits. In fact a 2017 study found that when combined with black pepper, curcumin (turmeric) has its ability to be absorbed increased by a whopping 2000%. And you only need a pinch of pepper for this to happen.
