Scientific Advisory Group

The Nutritional Science Research Institute is pleased to act as the Scientific Advisory Group for the Greens Plus Family of Products.

Jack F. Bukowski, MD, PhD Chief Scientific Officer for the Nutritional Science Research Institute (NSRI)

"Based on the hundreds of independent studies exhibiting the beneficial effects of the ingredients, I believe that Greens Plus delivers the essential vitamins, minerals, amino acids, antioxidants and enzymes needed for good health and provides the fundamentals essential to a nutritious diet."

Dedicated to the study of the human immune system for over 30 years, Dr. Bukowski began his research career in 1974, while an undergraduate student at Johns Hopkins University to ultimately hold a post as Assistant Clinical Professor of Medicine at Harvard Medical School. Dr. Bukowski is an advisor to the Department of Defense on matters of bioterrorism readiness, and has spent the majority of his career researching the specific factors that encourage a strong, healthy immune system. He has authored over 100 research articles, abstracts, and review articles for many scientific journals, newspapers, and magazines such as Time, US News and World Report, National Geographic, and Discovery and has been featured on Today, Good Morning America, and CNN News.

In 2005, Dr. Bukowski founded the Nutritional Science Research Institute to incorporate his impressive research discoveries into developing products for better health. In 2008, NSRI will conduct a double-blind, placebo-controlled clinical trial that will explore the antioxidant, anti-inflammatory, immune-enhancing and pH balancing effects of the original Greens Plus formula. Dr. Bukowski will direct the project in conjunction with Dr. Sue Percival, Professor of Food and Nutrition Science at the University of Florida.
