Piperine (or Piperaceae) is the active compound in black pepper. When taken as a dietary supplement, Piperine has the ability to significantly improve the absorption and uptake of many dietary supplements. Piperine is used for its ability to inhibit phase 2 detoxifying enzymes and to prevent the process of glucuronidation.
Piperine is the alkaloid responsible for the pungency of Black Pepper, giving Black Pepper its medicinal properties.
Piperine may also slow intestinal removal of supplements. These effects allow your body to better absorb many supplements (non-endogenous supplements that are metabolized by the liver). The recommended serving size for Piperine is 20mg. Do not use Piperine if you are taking any medication.
