Turmeric (Latin: Curcuma longa) is a spice obtained from the underground stem (rhizome) of the plant of the same name, characteristic of the regions of India and Southeast Asia. Turmeric has a rich history in India as a spice, preservative, and coloring agent, and for centuries has been used in Ayurvedic medicine where it is well-documented as a natural medicinal substance.
The characteristic yellow color of turmeric is due to the polyphenol curcumin, an active ingredient from the group of curcuminoids.
Native curcumin is quickly eliminated unused from the body, thus it has extremely low bioavailability.
What is bioavailability?
Bioavailability is the ratio of the amount of nutrients taken into the body to the amount of nutrients actually digested, absorbed, and metabolized by conventional biochemical processes. It represents the portion of a drug or dietary supplement dose that is actually available to act at the targeted site.
Bioavailability is an important factor in the effectiveness of a product, but not the sole criterion for comparing and evaluating its efficacy.
To enhance the bioavailability of Turmeric 95% Extract BioPerine, piperine, a component of black pepper, specifically its patented and protected form BioPerine, has been added. This enhances the action and absorption of curcumin into the body’s cells by up to 20 times.

A clinical study from St. John’s Medical College, published in Planta Medica, provided clinical evidence of the role of piperine in increasing the bioavailability of curcumin (Majeed M. et al. (1998). Planta Med.;64(4):353-356).
