Study summary and findings:
Daily consumption of Juice Plus+ for eleven weeks effectively increased plasma levels of important antioxidant nutrients and led to an improvement in a marker of immune function and reduction of DNA damage in law school students.
This research determined the effect of Juice Plus+ on phytonutrient status, on markers of immune function, and on lymphocyte (white blood cell) DNA structural integrity as measured by resistance to damage. Fifty-nine (59) healthy law school students participated in this study. Subjects consumed Juice Plus+ capsules daily for 77 days (eleven weeks). Blood for antioxidant analysis and to obtain lymphocytes was collected at baseline, day 35 and day 77. This study found an increase in a specific type of T cell (gamma delta) which plays a role in protecting the body from microbes associated with infectious illness. In addition, a significant decrease over baseline values in susceptibility to DNA damage after consumption of Juice Plus+ at both 35 and 77 days and a significant increase over baseline values for the phytonutrients beta-carotene, lutein, lycopene, and vitamin C were also observed.
