Curcumin is not well absorbed if taken by alone but adding quarter teaspoon of black pepper, curcumin levels skyrocket. The same amount of curcumin consumed, but the bioavailability shoots up 2,000 percent. Even just a little pinch of pepper—1/20th of a teaspoon—can significantly boost levels.”
Also use curcumin with fat. “Turmeric needs to be combined with a fat in order for your body to fully absorb it and experience its amazing health benefits. When eaten with healthy fats, such as coconut, ghee, or olive oil, curcumin can be directly absorbed into the bloodstream through the lymphatic system thereby in part bypassing the liver.”
You can also try heating turmeric, sauteing it in about half a teaspoon of oil in a saucepan and then adding it to your cooking.
