The Acute Effect of a Theacrine-based Supplement on Mobilization of Various Stem Cell Populations.
January 12, 2024 updated by: University of Memphis
The goal of the study is to determine the acute and short-term supplementation effect of a commercially available theacrine-containing supplement (NAD3) on numbers of various circulating stem cell populations in older adults.
Study Overview
Detailed Description
This is a double-blind, placebo-controlled crossover study with 12 participants randomized to receive either NAD3® or a placebo for seven days.
Blood samples are collected after an overnight fast, before and after the seven-day supplementation period, as well as one and two hours after the final supplement/placebo dose.
Using flow cytometry, circulating stem cells, including lymphocytoid CD34+ stem cells (CD45dimCD34+), stem cells associated with vascular maintenance and repair (CD45dimCD34+CD309+), CD34+ stem cells linked to a progenitor phenotype (CD45dimCD34+CD309neg), circulating endothelial stem cells (CD45negCD31+CD309+), and mesenchymal stem cells (CD45negCD90+) are quantified.
