"Bioperine" is a nutritional supplement that may have significant impacts on human metabolism and the bioavailability of vitamins and minerals within the body. The main active ingredient in Bioperine is piperine. A cheap, natural food-source of Bioperine's main ingredient exists, but it comes in only one flavor: spicy.
Piperine--the main active ingredient in Bioperine--is derived almost exclusively from black pepper (Piper nigrum). The only other edible source of piperine is the fruit of the long pepper plant (Piper longum).
The main ingredient of Bioperine is 1-peperoylpiperidine ("piperine"). Piperine is a pungent chemical and has a decidedly peppery or spicy taste.
Although you can get piperine in your diet naturally from black pepper, it would be very difficult to consume enough black pepper to match a daily dose of Bioperine. Additionally, Bioperine's manufacturer claims that its "purified extract of piperine" is more effective than consuming black pepper alone.
Piperine may positively impact metabolism and have a significant antioxidant effect.
Black pepper is a spicy food that should be eaten in moderation. You should consult a medical professional before undergoing a nutritional supplement regimen or consuming abnormally large quantities of any food.
