Here is some info for you about absorption of resveratrol with piperine.
Below is a study from the University of Illinois where they tested absorption rates for resveratrol when combined with piperine, the results were amazing to say the least.
Enhancing the bioavailability of resveratrol by combining it with piperine.
Department of Pharmacy Practice, College of Pharmacy, University of Illinois at Chicago, Chicago, IL, USA.
METHODS AND RESULTS:
Employing a standardized LC/MS assay, we determined the effect of piperine co-administration with resveratrol on serum levels resveratrol and resveratrol-3-O-β-D-glucuronide in C57BL mice. Mice were administered resveratrol (100 mg/kg; oral gavage) or resveratrol (100 mg/kg; oral gavage)+piperine (10 mg/kg; oral gavage), and the serum levels of resveratrol and resveratrol-3-O-β-D-glucuronide were analyzed at different times.
We found that the degree of exposure (i.e. AUC) to resveratrol was enhanced to 229% and the maximum serum concentration (C(max)) was increased to 1544% with the addition of piperine.
CONCLUSION: Our study demonstrated that piperine significantly improves the in vivo bioavailability of resveratrol. However, further detailed research is needed to study the mechanism of improved bioavailability of resveratrol via its combination with piperine as well as its effect on resveratrol metabolism.
