The following publications are of relevance to athletes as they demonstrate, among other benefits, immune stabilization and reduction of oxidative stress. The last two cited publications show that Juice Plus+ provides bioavailable polyphenols and other phytonutrients. 

1. Lamprecht et al 2007, Journal of Nutrition 137:2737-2741. https://academic.oup.com/jn/article/137/12/2737/4750748

Data of this study suggest that Juice Plus+® improves stability of the immune system, with regard to reduction of duty days lost due to illness, and reduces oxidation and inflammation in a group of trained men. Data from this study suggests that JP+ reduces oxidation in a group of trained men.  

2. Lamprecht et al 2013, Medicine and Sport Science 59:70-85. https://www.karger.com/Article/Abstract/341960

This review indicates that Juice Plus+ helps to manage oxidative stress in athletes.

3. Nantz et al 2006, Journal of Nutrition 136:2606-2610. https://academic.oup.com/jn/article/136/10/2606/4746704

This paper describes the increase in plasma nutrients and antioxidant capacity, reduction in DNA strand breaks, and an increase in immune cells in stressed but healthy law students after 11 weeks of Juice Plus+® intake. 

4. Lamprecht et al 2015, Antioxidants in Sport Nutrition, Chapter 12. https://www.ncbi.nlm.nih.gov/books/NBK299051/

This book chapter reviewed the literature on fruit and vegetable concentrates in regards to redox homeostasis and immune stabilization in exercising people. It also provides a “decision path” for sport nutrition advisors to guide them whether supplementation with a fruit and vegetable concentrate is indicated.

5. Bloomer et al 2006, Medicine and Science in Sports and Exercise 38(6):1098-1105. https://journals.lww.com/acsm-msse/fulltext/2006/06000/Oxidative_Stress_Response_to_Aerobic_Exercise_.13.aspx

  Data of this randomized, double-blinded, placebo-controlled trial demonstrate that supplementation with Juice Plus+ attenuates protein oxidation in trained men and women.

6. Lamprecht et al 2009, Medicine and Science in Sports and Exercise 41(1):155-163. https://journals.lww.com/acsm-msse/fulltext/2009/01000/Protein_Modification_Responds_to_Exercise.18.aspx

Another paper which demonstrates the protection of proteins against oxidation after Juice Plus+® supplementation in trained men. 

7. Jin et al 2010, Molecular Nutrition and Food Research 54:1-9.

https://onlinelibrary.wiley.com/doi/abs/10.1002/mnfr.200900579

This study demonstrates the anti-inflammatory properties of Juice Plus+® in 117 healthy subjects.

8. Cui et al 2012, Molecular Nutrition and Food Research 56:666-670. https://onlinelibrary.wiley.com/doi/abs/10.1002/mnfr.201100496

In the second publication of this research project (1st paper is Jin et al 2010) the researchers demonstrate the ability of Juice Plus+ to protect DNA from oxidation.

9. Lamprecht et al 2013, British Journal of Nutrition 110:1685-1695. https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/supplementation-with-a-juice-powder-concentrate-and-exercise-decrease-oxidation-and-inflammation-and-improve-the-microcirculation-in-obese-women-randomised-controlled-trial-data/451DF71104D867B79B1AB87E6326943A

This study shows the effective and beneficial influence of Juice Plus+® on markers of redox biology in overweight but physically active women.

10. Bresciani et al 2015, Pharma Nutrition 3:11-19.

This study measured polyphenol concentrations in Juice Plus+® and suggests a concentration of about 600mg in daily dose (equivalent to 6 capsules).

11. Bresciani et al 2017, Nutrients 9:194; doi:10.3390/nu9030194. https://www.mdpi.com/2072-6643/9/3/194

This paper demonstrates that many phenolic compounds in Juice Plus+ are also absorbed in physiological relevant amounts.
