Bioavailability Study of Cinnamon in Healthy Subjects

Completed · Phase 1/Phase 2

Conditions studied: Healthy Males

In brief

A partial double-blind, randomized, placebo-controlled, 4-treatment crossover study design will be used to evaluate bioavailability of various forms of cinnamon and to determine the effects of 3 and 6 g of cinnamon added to instant oatmeal on blood glucose levels in 8 healthy subjects. In the extended dose response study, three subjects will continue the study and be offered 5 day consecutive feedings of 9 g cinnamon extract and on Day 6, and blood samples would be collected over 6 hours after a single morning dose.
