Turmeric is a spice that has been used for millennia for its medicinal purposes.  Today, modern science is starting to pay attention to the spice as a source of curcumin, a chemical with strong anti-oxidative, antimicrobial, anticancer, and anti-inflammatory properties. Curcumin by itself, however, suffers from poor bioavailability, poor absorption, rapid metabolism, and rapid elimination. This is where piperine comes in. Piperine, an alkaloid in black pepper, when combined with curcumin, has been shown to increase bioavailability by 2000 percent. ⠀⠀⠀⠀⠀⠀⠀⠀⠀
A piperine-circumin complex was offered to 30 adults over 10 weeks in a randomized double-blind trial, which found that a 500-mg dose elicited a significantly better response to Beck Anxiety Index scores than placebo after four, six, and 10 weeks. The effects on Beck Depression Inventory scores were negligible. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
One easy way we incorporate curcumin-piperine into our diets is by dusting scrambled eggs with turmeric and sprinkling on ground black pepper.
