5. Study Description

Brief Summary
The purpose of this study is to determine whether there is a difference in the human in vivo response to 13C-Spirulina meals manufactured using 13C-Spirulina containing different levels of protein (as measured by %nitrogen).
Detailed Description
In this study participants will be administered the standard FDA-approved GEBT in which the test meals contain 13C-Spirulina that has 7.9% Nitrogen content. On a second occasion, a low nitrogen GEBT in which the test meal will contain 13C-Spirulina with a 6.4% Nitrogen content will be administered. Both sets of GEBTs have been manufactured under full cGMPs and both will be administered to the participants according to the FDA-approved GEBT labeling. The two in vivo results of the two independent GEBT test administrations in the study cohort will be compared to determine whether there is any significant different in in vivo 13CO2 signaling.
