Clinical Trial on Rapid Effects on Stem Cell Surveillance. A Randomized Placebo-controlled Acute Cross-over Trial.

• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 48 (estimated)
• Sponsor: Natural Immune Systems Inc · Academic / Other
• Sex: All
• Age: 18 Years – 75 Years
• Healthy volunteers: Accepted

Summary

The goal for this clinical trial is to compare acute immune effects of three nutraceutical ingredients and blends to a placebo.

Detailed description

The goal for this clinical trial is to compare acute immune effects of anthocyanin-rich botanical extracts and blends to a placebo. Stem cell mobilization and homing will be evaluated through monitoring of changes to the numbers of various types of stem cells in the blood circulation. The testing will show whether consuming the active test products lead to changes in stem cell numbers in circulation above the normal circadian changes for each participant. The normal circadian changes are documented on the clinic visit where placebo is consumed. Several different stem cell populations will be evaluated using flow cytometry.
