Black Pepper Fruit Extract. Suitable for Vegetarians. BioPerine® is a pure form of piperine derived from the fruits of black pepper. Studies indicate that BioPerine® promotes nutrient absorption. This is due to BioPerine®'s interaction with the surface of the intestinal tract. BioPerine® is non-irritating to the gastrointestinal tract.
"BioPerine (black pepper fruit extract) is indeed an important supplement to take to help the absorption of other supplements, but unfortunately, the tablets in this case are not coated at all, and I feel as though they are burning my esophagus on the way down, even though I drink plenty of water with them. I think that a capsule would be a better form for this supplement."
