The main purpose of this study is to determine the oral bioavailability of flavanols (polyphenolic compounds) from apple granules and an apple extract delivered in a water based beverage at two different doses. We will also investigate the effects of apple flavanols on nitric oxide production.
This study is a randomized four phase crossover trial investigating the bioavailability of apple flavanols and the effects on nitric oxide products, a surrogate marker for changes in endothelial function. Each test phase will comprise a 3 day period of intervention which will be identical in nature (except for the test product consumed) and separated by a minimum of 1 week. On days 1-3 of each test phase volunteers will consume a low flavanol diet. After consumption of the test product on the morning of day 2, blood and urine samples will be collected at regular intervals for the next 24h.
Allocation: Randomized, Endpoint Classification: Bio-availability Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Basic Science
