■ NUTRITIONAL OUTLOOK 38 JUNE 2018 Antioxidants study to these two previous investigations wherein they plan to examine the ef ects of trans-resveratrol on cerebrovascular function, cognitive performance, and bone health in a longer crossover trial involving 160 postmenopausal women. "First results from this study are expected by mid-2019," he says. Stronger Together Resveratrol, notes Sabinsa's Majeed, is poorly bioavailable. "T ough a number of human clinical trials have been performed over the years," he says, "conf icting f nd- ings have precluded its applicability in clinical settings, partially due to this poor bioavailability." Yet in a randomized, double-blind, place- bo-controlled clinical trial 3 published in 2016 in the journal Applied Physiology, Nutrition, and Metabolism, researchers investigating the combined ef ects of resveratrol supple- mentation plus exercise on human skeletal muscle mitochondrial capacity coincidental- ly demonstrated that piperine, "a natural bio- enhancer from black pepper that research shows enhances bioavailability for a variety of nutritional substances," Majeed says, ap- pears to also enhance the bioavailability of resveratrol. T e study used Sabinsa's propri- etary piperine ingredient, BioPerine. In the trial, 16 healthy young adults un- derwent four weeks of supplementation with resveratrol at 1,000 mg and piperine at 20 mg. Results showed that volunteers in the res- veratrol-piperine group demonstrated sig- nif cant muscle oxidative capacity recovery following short bouts of exercise compared to the placebo group. Notes Majeed, "T e in- f uence of resveratrol on low-intensity stim- ulus during submaximal endurance training is one of the most eye-catching recent f nd- ings." T e current data, he said, "could be signif cant to the general population, espe- cially to those who may be unable to perform high-intensity exercise." References 1.
